Abstract
Many movie markets are characterised by extensive uniform pricing practices, ham-
pering the ability to estimate price elasticities of demand. Australia presents a rare
exception, with most cinemas offering cheap Tuesday ticket prices. We exploit this
feature to estimate a random coefficients discrete choice model of demand for the
Sydney region in 2007. We harness an extensive set of film, cinema, and time-
dependent characteristics to build a rich demand system. Our results are consistent
with a market expansion effect from the practice of discounted Tuesday tickets,
and suggest that cinemas could profit from price dispersion by discounts based on
observable characteristics.

“One of the more perplexing examples of the triumph of convention over rationality
is movie theatres, where it costs you as much to see a total dog that’s limping its way
through its last week of release as it does to see a hugely popular film on opening night.”

1 Introduction
Product differentiation in movies is self-evident to even the most casual enthusiast. How-
ever, as Orbach and Einav (2007) discuss in detail, to the puzzlement of many observers,
the practice of (almost) uniform pricing is a long-standing feature of the market for movies
screened in cinemas.
1
The Australian cinema market offers a rare partial exception. For
example, in Sydney almost all cinemas offer discounted tickets every Tuesday for the entire
day.
2
Based on typical multiplex prices, this reduces the price of an adult ticket by about
40%, a student ticket by about 25%, and a child ticket by about 20%. We exploit this
rare (and arguably exogenous) price variation in the Sydney cinema market to estimate
the demand for cinema using a comprehensive data set of daily film revenues for cinemas
in the greater Sydney region over the year 2007.
Our first goal is to investigate whether this experiment with discounting has been
successful. Has it led to an increase in cinema attendance, or has it simply induced
consumers to switch the timing of their attendance? The purpose of discounted pricing
is typically to lure consumers into the market and away from competitors. In the case
of the Sydney cinema market, discounting is quite well coordinated across cinemas with
almost all cinemas engaging in “cheap Tuesday” pricing. In aggregate then, cinemas are
likely to benefit only if discounting leads to a market expansion.
To tackle this problem, we consider two alternative market definitions in our demand
specification. Our daily market definition includes all films exhibited on a specific day in
the choice set of each consumer. An outside good is also available, permitting consumers
to opt out of the movie market. Discounting can then lead to substitution away from
the outside good or other movies offered on the same day, but not substitution away
from movies on other days of the week. By not allowing such temporal substitution, this
definition could overstate the market expansion due to cheap Tuesday pricing. Our weekly
market definition is designed to address this problem by including all films screening over
the week within the choice set of each consumer.
3
Using this definition, we can examine
whether discounting has led to substitution away from the outside good or substitution
away from other films offered during the week.
1
Orbach and Einav (2007) provide detail that during the pre-Paramount era (i.e. before 1948) variable
pricing strategies were used with respect to films categorised by quality. This practice subsequently
continued into the 1950s and 1960s where ‘event’ movies were often priced above other movies. Price
variation between weekends and weekdays and by type of seat within an auditorium was also evident.
This kind of price variation has more recently been largely absent in most markets. Orbach and Einav
(2007) conclude that exhibitors could increase profits if they practiced variable pricing strategies.
2
In the U.S. on certain days matinee performances may be priced lower, but not the evening sessions
where there is likely to be more demand.
3
We thank Philip Leslie for suggesting this alternative market definition.
2
Our second goal is to examine the potential profitability of additional price dispersion.
Despite weekly discounting, a remarkable degree of price uniformity remains in the Syd-
ney market. In particular, we observe the two pricing puzzles discussed by Orbach and
Einav (2007): i) the ‘movie puzzle’ (why different movies attract the same price); and
ii) the ‘show-time puzzle’ (why different times, days, and seasons are priced uniformly).
Armed with our demand estimates, we simulate optimal pricing for different types of films,
ranging from a film in the middle of its run to an opening week film to a blockbuster in
opening week. This allows us to examine the returns to price adjustments for different
categories of films.
Price uniformity itself hampers attempts to formulate an optimal pricing strategy.
Without variation in price, demand elasticities cannot be inferred from the data, and the
enterprise is destined for failure. An additional contribution of our work is then to obtain
demand estimates in a setting with substantial price variation. We observe prices that
vary by around 30% in every week of the sample for each cinema-film pair. We also make
use of a rich data set, enabling us to estimate a detailed characteristics-based demand
system. In particular, we control for film characteristics (e.g. genre, budget, advertising,
reviews, cast appeal), theatre characteristics (e.g. location, number of screens), the day
of observation (e.g. day of week, public/school holidays, weather), and the demographics
of the local population (e.g. age, income).
We adopt a random coefficients discrete choice model of demand. We define a product
as a combination of a film, a theatre and day of screening. There are a large number
of such products in our sample, making a characteristic-based estimation strategy the
only feasible means of extracting the full set of cross-price elasticities. To accommodate
heterogeneous preferences for movie offerings, our strategy is based on the empirical model
of Berry et al. (1995) (hereafter, “BLP”). Following Nevo (2001), we permit heterogeneity
in “observable” characteristics (local region-specific demographic characteristics) as well
as “unobservable” characteristics; and we include movie-specific fixed effects. Following
Davis (2006), we incorporate a spatial dimension to product characteristics that accounts
for travel costs. In the spirit of Imbens and Lancaster (1994) and Petrin (2002), we include
additional moment conditions based on external population demographic data.
Our estimation strategy relies on the assumption that the demand for movies on Tues-
days is essentially the same as for regular weekdays. That is, we assume the choice of
Tuesday (as opposed to Monday, Wednesday or Thursday) as the cheap ticket day is not
related to demand conditions.
4
Under this assumption, an indicator variable for Tuesdays
represents a valid instrument for prices.
5
Moreover, it is an important instrument, ac-
counting for much of the variation in prices. We note that we are unable to explicitly test
this assumption. Because the vast majority of weekly price variation is due to Tuesday
discounts, we are unable to separately identify variation in attendance on Tuesdays from
4
Our correspondence with industry participants has not yielded a conclusive explanation for the emer-
gence of “Cheap Tuesdays”. However, the propensity for public holidays to fall on Mondays and new
movies to be released on Thursdays suggests a narrowing down of the available days for an off-peak
discount that is unrelated to demand (once we control for public holidays and opening days).
5
In fact, in estimation we include a ‘cheap day’ dummy variable as four independent cinemas actually
offer a cheap Monday ticket and one cinema offers a cheap Thursday ticket in our sample. Further details
are provided in Section 4.

variation in price on Tuesdays. However, we have no reason to suspect demand differs
systematically between Mondays, Tuesdays, Wednesdays, and Thursdays. A consequence
of this choice of instrument is that much of the identification of the price elasticity of
demand stems from temporal variation in prices as opposed to cross-sectional variation.
The profit maximisation problem of a cinema is a complicated one. In particular, we
see the consideration of ancillary sales to be an important issue. We are not armed with
data to rigorously tackle this problem.
6
Accordingly, we do not introduce supply side
moment conditions, but rely only on our demand model to estimate demand parame-
ters. Instead, given our estimated demand parameters, we consider the cinema’s revenue
maximisation problem in the absence of concerns about ancillary sales. Given the likely
positive relationship between cinema attendance and concession sales, we argue that this
places an upper bound on the cinema’s profit-maximising prices.
As in most applied settings, our data constrain the performance of our estimation
strategy. In particular, we rely on repeated observations of a single (large) geographic
market. This provides cross-sectional variation between connected local markets, but
not between geographically separated markets. Our data exhibit intra-week temporal
variation in price, but no other systematic time-series price variation; and cinemas charge
the same price for all movies screened on a given day. Hence, it is intra-week temporal
variation in price coupled with cross-sectional variation at the level of a cinema (rather
than a film) that identifies our demand estimates. Further, films tend to be introduced
simultaneously across multiple cinemas, constraining our ability to identify heterogeneity
in preferences for films. We return to these issues in the discussion of our results.
To preview our results, consistently across the set of specifications we consider, we
observe that: cinema demand is relatively elastic, with the median own-price elasticity of
a film-at-theatre around 2.5 or higher; cross-price elasticities are quite low, leading us to
believe that much substitution takes place with the outside good; and there are intuitive
relationships between cinema attendance and a range of film-, cinema-, and time-specific
characteristics. Both our daily and weekly models suggest that the effect of discounting
has been not only a market expansion, but an increase in revenue. Finally, our revenue-
maximisation problem is consistent with systematic overpricing for a substantial subset
of cinema tickets. For a typical film in our dataset, our demand estimates suggest that
a price reduction would raise revenue without stretching screening capacity. However,
for a subset of films (such as opening week films with wide release), it is plausible that
screening capacity could be constrained in the presence of substantial discounting.
7
Our research bears most similarity in its method to the studies of Davis (2006), Einav
(2007) and Moul (2007, 2008) in that we adopt a discrete choice approach to modeling de-
mand. Einav (2007) and Moul (2007) both employ nested logit models on weekly revenue
data (observed at the national level), exploring seasonality of demand and word-of-mouth
6
By contrast, Davis (2006) and Moul (2008) attempt to overcome this problem by imposing assump-
tions about the relationship between these variables based on aggregate industry data.
7
It is worth noting that we perform a demand estimation exercise rather than a forecasting exercise.
Cinema managers are likely to have additional information at their disposal such as film- and session-
specific attendance information as it develops. If our demand study reveals opportunities to profitably
vary price based on observable information, a forecasting exercise could be even more revealing. However,
an important complicating factor is the role of word-of-mouth.

effects, respectively, whilst Moul (2008) uses similar data to explore distributor conduct
in terms of rental pricing and advertising. Our data and method, however, most closely
resembles Davis (2006) in that we use daily film-at-theatre revenues and follow the ap-
proach of Berry (1994) and Berry et al. (1995) by employing a random coefficients model.
Like Davis (2006), we exploit information about the spatial distribution of consumers
and theatres in our empirical strategy. Relative to the dataset harnessed by Davis, our
data has a more extensive time-series dimension (365 days compared to seven), but a
more limited cross-section dimension (we only observe one distinct (geographic) market,
in contrast to his 36).
The paper is organised as follows. In section 2 we provide a brief background of the
Australian industry and the specific market we consider. In section 3 we outline the
discrete choice demand framework. In section 4 we describe the data set. In section 5 we
describe the estimation procedure. In section 6 we discuss the results, and in section 7
we conclude.
2 Industry background and market characteristics
As in many other countries, distribution and exhibition are both highly concentrated in
the Australian industry, with concentration of exhibition especially pronounced as the two
largest theatre circuits (Hoyts and Greater Union) account for more than 77% of sales
in our sample.
8
Theatrical distribution is dominated by the six major U.S. based studio
distributors who account for 75% of turnover in our sample.
9
This is also reflected in the
number of U.S. productions released relative to the local content. Of the 314 films which
opened in 2007, 172 of these were of U.S. production origin whilst only 26 were recorded
as Australian by the Motion Picture Distributors Association of Australia (MPDAA).
Although the cinema industry may be regarded as small by other industry standards, it
is by far the largest of the cultural sectors of the economy and in 2007 took over 895m
Australian dollars (A$) in box office receipts (MPDAA).
The relationship between film distributors and cinema exhibitors operating in the Aus-
tralian market is in many respects similar to the U.S. model. As in the U.S., distributors
and exhibitors operate at ‘arms length’, and the typical exhibition contract resembles
those observed in many other countries with a share division of box office revenues which
shifts in favour of the exhibitor in the later weeks of a film’s run.
10
In Australia, the
general rate of ‘film rental’ (the portion of box office remaining with the distributor) is
commonly acknowledged to be in the region of 35-40%.
As is the case in most other countries, Australian distributors are legally precluded
from specifying an admission price in the exhibition contract, but can choose not to
8
In our sample, the Hirfindahl-Hirschmann index is 0.33 for exhibition and 0.11 for distribution.
9
This figure also includes Roadshow who, whilst not a U.S. studio, operate a joint distribution ar-
rangement with Warner Bros. Roadshow is also jointly owned by major exhibition companies Village
and Greater Union.
10
Unlike many U.S. exhibition contracts, however, Australian exhibition contracts do not usually in-
clude the exhibitor’s fixed costs known commonly as the ‘house-nut’. The first week splits are therefore
usually in the order of 60/40 revenue for the distributor/exhibitor rather than as much as 90/10 as is
often the case in the U.S.
5
supply a cinema should they deem the admission price too low to be profitable for them.
Exhibitors naturally prefer a lower session price than a distributor given that they receive
high profit margins from the sales of popcorn, drinks and other snacks.
3 Model
3.1 Demand
We employ a random coefficients discrete choice model to estimate demand (see, for
example, Berry (1994); Berry et al. (1995); and Nevo (2001) for a detailed discussion
of this class of model). Our model most closely resembles that of Davis (2006), and
we follow his exposition. Consumer choices depend on film and theatre characteristics.
The indirect utility enjoyed by consumer i by attending film f {1, . . . , F

includes time-varying film characteristics (e.g.
an opening day indicator and week of run indicator variables), theatre characteristics
(e.g. number of screens, shopping centre location), and the time of screening (e.g. day of
week, public or school holiday, weather). In the spirit of Davis (2006), consumers incur
travel costs, with d

i and theatre h. Film-specific fixed effects are captured by φ

. Time-invariant film
characteristics (e.g. budget, advertising, reviews, cast, genre) are then recovered in an
auxiliary regression in the manner of Nevo (2001). The remaining error structure includes
a common component, ξ
fht
, capturing remaining unobserved product heterogeneity once
film fixed effects, φ

, have been accounted for; and an idiosyncratic term,

type-I extreme value distribution.
Consumer heterogeneity is embedded in our definition of a consumer type, τ

and

heterogeneity in preferences over price (α

We define the scope of the market to be the greater Sydney region within 30km of a
cinema, yielding a market size of just over 4 million people.
13
We consider two separate
definitions of a market. Our first definition equates a market with a day: consumers
choose between all available films (plus the outside good) on a given day. This definition
presumes that consumers see at most one movie each day. More restrictively, it prevents
substitution between films on different days. Under this definition, the set of consumer
types who choose film f at theatre h on day t is

are the (H

are the (H

and θ = (α, β, λ, Π, Σ) is a vector of parameters. Our second definition equates a market
with a week. This permits substitution between films on different days of the week, while
imposing a maximum of one film per week on our consumers. With the majority of new
releases occurring on Thursdays, we define a week as the period Thursday to Wednesday.
Equation (4) is analogously defined in this context.
The market share of film f at theatre h on day t is then given by

where the notation P

the equality in equation (5) follows from Bayes’ rule and the assumption of independence
of the error terms (, ν) with location, L, and demographics, D. Again, equation (5) can
be defined in either the daily or weekly market context.
3.2 Simulation of revenue-maximising prices
Plausibly, the marginal cost of the attendance of an additional patron at a capacity
unconstrained cinema is zero. A cinema manager could thus focus on maximising revenue
if a session is not expected to sell out. However, the manager must also account for the
important role played by concession sales.
14
We do not have data on concession sales or
session-specific attendance rates. Accordingly, we do not attempt the joint estimation of
parameters of the cinema’s profit maximisation problem. Instead, we simulate revenue-
maximising prices given our estimated demand parameters. Effectively, this delivers us

Additional details are contained in Section 4.3.

and concession sales.
7
the film- and theatre-specific profit-maximising price for capacity unconstrained sessions
were cinema managers to be unconcerned with concession sales. In our sample, average
attendance rates are low (we discuss this in more detail in Section 6). Thus, we view the
omission of concession sales to be the more serious limitation. If sales of concession items
are positively related to cinema attendance (as we would expect), then our simulation
exercise places an upper bound on profit-maximising prices given our estimated demand
parameters.
For exposition, let us start by assuming the manager of cinema h seeks to maximise
the static profit of cinema h. She then solves the following problem at time t:

We consider four alternative definitions of the ownership matrix
t
, corresponding to
four forms of theatre competition. First, we consider the possibility outlined above that
theatre managers seek to simply maximise profits of their own theatre:
t
(f, g) = 1 if
films f and g are exhibited at the same theatre at time t, and 0 otherwise. Next, we
account for the ownership structure of theatres by assuming that each theatre manager
seeks to maximise the profits of the “circuit” (owner) to which her theatre belongs. That
is,
t
(f, g) = 1 if films f and g are exhibited at theatres belonging to the same circuit
at time t, and 0 otherwise. Third, we consider market structure at the distributor level
by assuming that distributors choose prices to maximise the profits of their basket of
exhibited films. That is,
t
(f, g) = 1 if films f and g are associated with the same
distributor, and 0 otherwise. Finally, we also examine the joint-revenue maximisation
problem of the industry by defining
t
as a matrix of ones.

4 Data
4.1 Film characteristics and other explanatory variables
The data used in this study are primarily derived from Nielsen Entertainment Database
Inc. (EDI). We observe every film at every cinema in the greater Sydney region playing
from January 1, 2007 until December 31, 2007. Nielsen EDI track daily revenues of all
films playing at all 61 cinemas in this region. This sample is reduced to 50 cinemas
by excluding Sydney’s Darling Harbour IMAX theatre, a number of open-air (seasonal)
cinemas, drive-ins, and occasional theatres on the grounds that they provide something of
a different product to the typical cinema experience. Of these 50 cinemas, 13 are owned
by Hoyts, 12 by Greater Union, four by Palace, three each by Dendy and United, with the
remainder being independents. One theatre (Merrylands, an eight screen Hoyts cinema
complex) closed midway through the sample on June 21, meaning we only observed 49
cinemas in the second half of the year. The locations of the 50 cinemas across the greater
Sydney area are shown in Figure 1. Across these 50 theatres 373 distinct titles were
recorded. From these, a further 59 films were dropped because they were either re-releases
(45 films), or had 6 or less screenings in 2007 (14 films). In total we observe 148,680 daily
film-at-theatre revenue data points over the 365 days of 2007. The daily film-at-theatre
revenue data consistently reflect large levels of skew and (excess) kurtosis. In our sample,
the average (median) daily film-at-theatre revenue was A$1,288 (A$569), with the top
earning film, Harry Potter and the Order of the Phoenix, making A$65,052 on its opening
day at Macquarie Megaplex.
Table 1 provides summary statistics of the 314 films used in estimation. Data is
incomplete in relation to some of these variables (in particular advertising, budgets, and
reviews).
16
Data on total box office revenue, opening week screens, and advertising were
sourced from the Motion Picture Distributors Association of Australia (MPDAA). At the
national box office level, the average film earned just over A$3.65m, but the median is
less than A$1m. As observed in the daily film-at-theatre revenues, the ‘hit’ films skew
the revenue distribution markedly as is apparent by the top film earning A$35.5m (Harry
Potter and the Order of the Phoenix )—more than five standard deviations above the
calculated mean.
17
The average opening week number of screens is also highly skewed,
with the largest opening film (Pirates of the Caribbean: At World’s End) taking up 608
screens. Budget data, derived from IMDb, Box Office Mojo, and Nielsen EDI, are also
skewed, with the most expensive film of the sample costing US$300m (Pirates of the
is likely to be confounded by a number of other considerations beyond the simple ownership structure
we have posited. For example, the exhibitor likely considers sales of popcorn, drinks and other snack bar
items in her objective function, while the distributor likely considers ancillary (potentially substitute)
markets related to DVD/Blu-ray sales or on-demand viewing. In addition, many exhibitors practice more
subtle forms of price discrimination with respect to loyalty programs and promotions which would affect
optimal price setting behaviour. Also, the repeated interaction between large distributors and exhibitors
might impact on the nature of price setting. This last consideration is a potential motivation for our
market-level definition of the ownership matrix Ω

to some of these possibilities.

We, in part, address this problem by the use of film fixed effects in estimation.

Reviews were compiled from weekly Thursday, Friday and Saturday editions of The
Sydney Morning Herald—the second largest circulation newspaper in Sydney and with the
most comprehensive set of film reviews available—based on a five star system. Although
there are many other review sources available to consumers, we argue this particular
source is likely to be amongst the most visible to Sydney filmgoers and provide the best
proxy for the potential effect of critical reviews. Also, because of the fact reviews from this
source generally appear before, on, or the day after release, this source is likely to capture
any potential ‘influence’ (beyond simply a ‘prediction’ effect) as discussed by Eliashberg
and Shugan (1997) and Reinstein and Snyder (2005). Review ratings were obtained for
257 out of the total 314 films of the sample.
We include a number of film-specific dummy variables to account for the effects of
sequels, stars, awards, genre, and rating. Sequel data were obtained from MPDAA and
Nielsen EDI and represent approximately 6 per cent of the sample. The ‘Star’ variable
was constructed using James Ulmer’s Hollywood Hot list, Volume 6, which rates stars
according to their ‘bankability’ as derived from survey results of numerous industry pro-
fessionals. We classify a star according to whether any of the leading actors were rated as
an A+ or A actor on the Ulmer list. Star films represent approximately 13% of all films
in our sample.
We also include two dummy variables for the effect of Academy Award nominations
and awards in the categories Best Picture, Best Actor in a Leading Role, and Best Actress
in a Leading role. For the 14 unique films which were nominated in these categories, we
assign a value of one to observations for dates equal to and beyond 23rd of January for
nominations, and a value of one to the three winners (The Departed, The Last King of
Scotland, and The Queen) for dates equal to and beyond the 25th of February. We include
three dummy variables for the main genre categories: action, comedy, and drama. The
numeraire category is the composite of all other genres.
18
Finally, rating is classified
under G, PG, M, MA15+, and R18+ as defined by the Office of Film and Literature
Classification.
In addition to the award-nomination/-win variables, which are obviously time-variant,
we consider other time-variant variables relating to what point of the run the film was at
the specific cinema of observation. We consider films at preview stage (mostly one week
prior to actual release), opening day at theatre, and week-of-run at theatre. As expected,
(unreported) average daily revenues decline at higher weeks of release. We account for
week-of-run in a relatively flexible manner by including individual dummy variables for
weeks 1-10.
19
We also consider school/public holidays and daily weather as important time-variant
explanatory variables in the local Sydney market. Consistent with Einav (2007), we
observe that films typically earn more on public and school holidays. Relative to Einav
(2007), our daily data suggests the additional insight that the peaks are most obvious
in the weekdays rather than the weekend days. We control for weather by including
measures of temperature and rainfall. Our temperature measure is the difference between

the daily maximum temperature and the monthly average, while rainfall is measured by
the daily rainfall. Both temperatures and rainfall are measured at Sydney’s Observatory
Hill weather station as recorded by the Bureau of Meteorology. We are only aware of
two recent studies (Dahl and DellaVigna (2009) and Moretti (2011)) that have considered
weather in broader models of movie demand.
4.2 Theatre characteristics, ticket prices, and admissions
Table 2 summarises the characteristics of the 50 theatres in our sample. There is con-
siderable heterogeneity across cinemas. The largest cinema, George St. in the heart of
Sydney CBD, has 17 screens and seating capacity in excess of 4,100, while the smallest
has just 64 seats. Cinemas located in shopping centres (known as multiplexes) account
for 21 of the theatres, with an average size of just under 10 screens.
Table 2 also includes pricing information by theatre. Our price and quantity data are
constructed from 3 sources. Dataset 1, our primary dataset, described above, contains
daily revenues by theatre and film. Dataset 2 contains pricing information disaggregated
by ticket type for each theatre. Most theatres in our dataset had a fixed menu of prices
throughout our sample, with prices varying by ticket type. In most instances, a sepa-
rate menu of prices operated on Tuesdays. Ticket price information was collected either
directly from the cinema, or from the Australian Theatre Checking Service (ATCS). In
instances where there had been a change in ticket price over the year, the highest price
was used.
20
Dataset 3 comprises annual revenue for the Greater Union national chain,
disaggregated by ticket type. In 2007, within their national chain, the revenue share
of ‘Adults’, ‘Students’, ‘Seniors’, and ‘Children’ was 44.7%, 13.1%, 10.9%, and 3.1%,
respectively.
21
Our primary revenue data are aggregated across ticket types while our price data are
disaggregated by ticket type. We therefore construct daily weighted average prices and
admissions by theatre and film. We use supplementary data on revenues for Greater Union
(Dataset 3), which is disaggregated by ticket type, to construct weights for different ticket
types. We then use these weights to calculate weighted average prices and quantities at
the theatre level, aggregated across ticket types.
More precisely, we use the following procedure. We use superscripts to specify datasets
and subscripts to indicate the dimension of variation, and abuse our earlier notation
slightly.

Using this method, the weights we apply are 0.56 to the price of an adult ticket, 0.21
to the price of a student ticket, 0.18 to the price of a child ticket, and 0.05 to the price of
a pensioner ticket. The weighted average ticket price ranged from $5.82 at Campbelltown
Twin-Dumares ($6 adult ticket), to $14.90 at Academy Twin ($16.50 adult ticket). The
nature of temporal variation in prices is highlighted by Table 2. With the vast majority
of theatres offering Tuesday discounts, the theatre-average price is substantially lower on
Tuesdays than for most other days. Four theatres offer cheap Monday tickets (all owned
by Palace) and one theatre offers cheap Thursday tickets (Mt. Victoria Flicks). Of the
remaining 45 theatres, only three independents do not offer cheap tickets.
Using our (weighted) average cinema ticket prices, the top panel of Table 3 provides
summary statistics of aggregated estimated daily admission across all cinemas by day of
week. The estimates suggest, on average, approximately 42,000 people (about 1% of the
population) attend a cinema each day in the greater Sydney area, and that Saturday is the
most popular day of the week followed by Sunday then Friday and Tuesday, which have
approximately equal average (and median) attendance rates. In fact, Tuesday records the
highest attendance in a single day across the sample period on January 2, 2007 where
almost 140,000 individuals were estimated to have patronised a cinema.
One of our critical assumptions in identification relies on the fact that weekdays
(Monday-Thursday) are implicitly treated the same by consumers. The top panel of
Table 3 suggests that Monday and Wednesday generate similar levels of attendance but
Thursday tends to attract more attendance. In Australia, however, films typically open on
a Thursday. In fact, of the 4,542 openings recorded in this sample, 3,988 (88%) opened on
Thursday. Once the opening day effect is removed from the week day summary statistics,
Thursday attendance is very similar to Mondays and Wednesdays as shown in the bot-
tom panel of Table 3. This is consistent with consumers treating all weekdays (excluding
Fridays) as equal. As discussed in more detail in Section 5, we exploit this observation in
our estimation strategy.
4.3 Market definition, demographics, and survey data
Our discussion of the data is complete with details of our market size, demographic infor-
mation, and the additional industry survey data we employ as extra moment conditions
in estimation. Table 4 reports summary statistics of the demographic variables we use,
based on Australian Bureau of Statistics (ABS) Census data from 2006. We include “col-
lection districts” (see Figure 2) whose centroid latitude and longitude coordinates place

12
it no further than 30kms from a theatre location. We use Google Earth to “geo-code” the
latitude and longitude of each cinema, and use this to create a distance variable from each
collection district to each cinema. All distances are calculated as driving distances. Using
our 30km definition, the total population of our market (the greater Sydney region) is a
little over 4 million people. Given that the official ABS population count is a little over
4.3 million, this gives us approximately 93% coverage of the market. Over this area, there
are a total of 6,587 collection districts with an average of 613 people in each. In our final
model, we restrict attention to demographic information on income and age. For these
variables we are able to construct an empirical distribution conditional on location. In
particular, the empirical distribution of age conditional on location, P (a|L), and the em-
pirical distribution of income conditional on age and location, P(y|a, L), are both available
from the Census. This allows us to construct P (D|L) = P (a, y|L) = P (y|a, L)P (a|L).
Finally, we exploit additional information on the profile of the cinema going audience.
In particular, we obtain cinema attendance rates by age in 2007 from Roy Morgan and
Co. Pty Ltd., and cinema attendance rates by income in 2006 from the ABS based on
the Attendance at Selected Cultural Venues and Events (cat no 4114.0). As discussed in
Section 5, we use this information to introduce an additional set of moment conditions.
The Morgan and ABS statistics suggest higher cinema attendance rates for younger people
and higher income earners.
5 Estimation
Our estimation strategy must account for the joint determination of prices and market
shares. Following Berry (1994) and BLP, we adopt a generalised method of moments
(GMM) estimator.
23
Our first set of moment conditions requires the existence of a set
of instrumental variables, Z = [z
1
, . . . , z
L
z
], that are correlated with market price, but
uncorrelated with the unobserved product characteristics, ξ:

where θ

represents the true parameter vector. For a candidate parameter vector, θ, we
solve for ξ(θ) in the usual way. First, we solve for the vector of mean utilities, δ

taken with respect to film, cinema, time, and individual characteristics. This set of
moment conditions thus places discipline on the model’s predicted conditional attendance
probabilities of different demographic groups.
Defining ˆg(θ) = [ ˆg

as a vector of sample equivalents of our population

where

gives less weight to moments with higher variance. Because we include the film fixed
effects, φ
f
, in equation (1), our GMM estimator does not identify the role of time-invariant
film characteristics in consumer choice. Following Nevo (2001), we perform an auxiliary
regression to recover these additional parameters.
An important component of the empirical strategy is the choice of instrumental vari-
ables. A great deal of intertemporal price variation stems from the common cinema
practice of offering discounted ticket prices on Tuesdays. We include a dummy variable
for the cheap ticket day in our instrument set. For most cinemas in our sample the cheap
ticket day is a Tuesday, for a small minority of four it is a Monday, and for a single theatre
it is a Thursday. Average attendance is relatively constant during the week with the ex-
ception of Fridays, weekends and opening days. We include dummy variables for Friday,
Saturday, Sunday, and opening day in our set of explanatory variables. Effectively then,
our maintained assumption is that the choice to offer cheap tickets on Tuesdays instead
of Mondays, Wednesdays, or Thursdays, is unrelated to demand conditions. BLP suggest
that rival product characteristics may provide useful instruments. Davis (2006) considers
the characteristics of rival theatres within five miles of the theatre, such as consumer
service, DTS, SDDS, Dolby Digital, Screens, THX, weeks at theatre, first week of na-
tional release, and local population counts (of different definitions). Accordingly, we also
include a range of other instruments which relate to i) the characteristics of the nearest
rival cinema including number of seats, number of screens and distance from the reference
cinema; and ii) the characteristics of all rival cinemas within a certain distance of theatre
h (e.g. total number of cinema screens, seats, or shopping centre theatres within [0,5],
and [0,10] kms of h).
For our additional moment conditions, we use information about attendance rates
conditional on age and income. In particular, we match attendance rates for the age
brackets {15-24}, {25-34}, {35-49}, and {≥ 50}; and the weekly income brackets {<
400}, {400-600}, {600-800}, {800-1000}, {1000-1300}, {1300-1600}, {1600-2000}, and
{≥ 2000}, where all figures are in Australian dollars.
We close this section by briefly discussing the nature of variation in our data that
identifies our parameter estimates. In principle, we can exploit time-series variation,
cross-section variation within the greater Sydney market, and, because consumers face
transport costs, some variation between local markets within Sydney. In practice, the
variation in price takes a restricted form. The primary source of time-series variation is
the common practice of offering cheap Tuesday tickets. There is very little other time-
series variation in price, with a small number of small theatres offering cheap tickets on
Mondays instead. This time series variation allows identification of the average price
14
sensitivity, α. However, to separately identify heterogeneity in preferences toward price,
we need variation in relative prices. For this we rely on cross-section variation in relative
prices of similar movies at neighbouring theatres in different areas.
There is sufficient heterogeneity in film offerings in our sample to identify mean pref-
erences towards film characteristics. We need variation in the mix of films to identify
heterogeneity in preferences towards film characteristics. In our sample, most new films
are introduced simultaneously in many theatres, limiting such heterogeneity. Accordingly,
we struggled to separately identify heterogeneity parameters relating to film characteris-
tics. We briefly return to this issue in the discussion of our results.
5.1 Identification
Our parameter estimates are identified by time-series variation, cross-section variation
within the greater Sydney market, and, because consumers face transport costs, some
variation between local markets within Sydney. In practice, the variation in price takes a
restricted form. Most cinemas offered a fixed menu of prices over our sample, with prices
varying by ticket type and day of the week. The primary source of time-series variation
is the common practice of offering cheap Tuesday tickets. In addition, a small number of
small theatres offered cheap tickets on Mondays instead. Cross-section variation is limited
by uniform pricing practices. Cinemas charge the same price for all offerings on a given
day. The source of cross-section variation is then price differences across cinemas.
The above price variation is sufficient to identify the average price sensitivity, α. In
fact, the depth and regularity of price discounting permits precise estimates of α. How-
ever, to separately identify heterogeneity in preferences toward price, we need variation in
relative prices. For this we rely on variation in relative prices of similar movies at neigh-
bouring theatres in different areas. The existence of a small number of cinemas offering
discounted prices on Mondays aids identification. As we discuss in the next section, we
found our estimates of heterogeneity to be sensitive to specification.
There is sufficient heterogeneity in film offerings in our sample to identify mean pref-
erences towards film characteristics. We need variation in the mix of films to identify
heterogeneity in preferences towards film characteristics. This variation was somewhat
limited, leading to challenges in identifying heterogeneity parameters. Accordingly, we
restricted attention to heterogeneity with respect to the week of run of a film. Variation
in week of run identifies mean preferences for recent movies, while we need variation in the
mix of film vintages to identify heterogeneity in such preferences. With the coordinated
release of new films, such variation was somewhat limited. We briefly return to this issue
in the discussion of our results.
Heterogeneity in movie attendance conditional on product characteristics identifies the
random coefficient on the constant. With regard to our demographic characteristics, we
require variation in attendance rates across cinemas surrounded by local regions exhibiting
differing demographic distributions. With a sample of 50 cinemas, we found that our
supplementary moment conditions (equation (11)) did much of the work in identifying
our age and income parameters, while similar moment conditions were not available to
assist in identifying our travel cost parameter.
Features of our data also had more fundamental implications for our demand model.
15
As an alternative to our random coefficients model, we also considered a variety of nested
logit models. The nested logit model incorporates heterogeneity by permitting substitu-
tion patterns to differ within and between groups. Relative to the MNL model, estimation
of the (single-level) nested logit model requires inclusion of an inside share variable as an
explanatory variable, where the inside share is the market share of a product within its
product grouping. The principal empirical challenge lies with the potential endogeneity
of this inside share variable; the inside market share of a product is likely related to unob-
served characteristics of the product. Instrumental variables are a common solution; for
example, Ho et al. (2012) and Einav (2007) use this strategy to estimate nested logit mod-
els in similar contexts. In these settings, the presence of multiple markets is an important
element of the instrumental variables strategy. In our setting, we are restricted to a single
market, hampering our ability to devise valid instrumental variables. Consequently, we
do not present estimates of the nested logit model.

6 Results
Parameter estimates are contained in Tables 5 and 6. Table 5 presents estimates of equa-
tion (1), while Table 6 presents the results of an auxiliary regression to recover parameter
estimates for time-invariant film characteristics. Columns 1-3 of Table 5 consider our daily
market definition, while columns 4-6 relate to our weekly market definition. Columns 1
and 4 present estimates of a simple multi-nomial logit (MNL) model in which our hetero-
geneity parameters are absent, while the remaining columns present estimates from our
random coefficients (RC) model. In our MNL model, demographic variables are included
as additional product characteristics and are considered as ‘distance rings’ around each
theatre following Davis (2006). For example, ‘Pop[0,5]’ and ‘Pop(5,10]’ measure the pro-
portion of the total population (approximately 4 million) living within 5 kilometres of
theatre h, and living between 5 and 10 kilometres from theatre h, respectively. An exam-
ple distance ring is provided in Figure 2. ‘log(Age)[a,b]’ and ‘log(income)[a,b]’ measure
the (log) weighted-averages of the median age and median income, respectively, of each
collection district within the distance ring [a,b], where weights are population proportion
of each collection district within the distance ring. Columns 2 and 5 contain estimates
of the RC model where we allow heterogeneity with respect to consumer location, age
25
Notice that our empirical setting presents different challenges for the nested logit and random co-
efficients models. In particular, the endogeneity problem that surfaces in the nested logit model is less
relevant for the random coefficients model. To see this, compare closely related versions of each model.
The nested logit model with two groups consisting of the outside good and all “inside” goods has similar
economic implications to the random coefficients model in which consumer heterogeneity is limited to
the constant term. Specifically, both models could generate the same substitution patterns. However,
the econometric challenges presented by each model are different. In the nested logit model, the nesting
parameter which determines substitution patterns is identified by the relationship between the normalised
market share of a product and its inside share. Inferring this relationship is complicated by the likely
correlation of the inside share with unobserved product characteristics. By contrast, with the random
coefficients model, the heterogeneity parameter is determined by the variance in the outside share condi-
tional on product characteristics. The relationship between unobserved product characteristics and the
variance in the share of the outside good is likely to be much weaker, and the same endogeneity problem
does not arise.
16
and income, and heterogeneity in preferences for the outside good and attendance in the
opening week of a film. In columns 3 and 6, we include, in addition, heterogeneity in
preferences over price.
The coefficients on price suggest that demand is relatively elastic. In the MNL model
and the RC model that omits the price heterogeneity term, the price sensitivity parameter
is in the vicinity of 0.2 for each specification.
26
This translates to a median film-level
own-price elasticity of around 3.34 for the daily RC model (column 2) and 2.45 for the
weekly RC model (column 5). This magnitude is similar to other (mostly time series)
studies which have found elastic own price demand.
27
Our estimates of mean preferences
towards price were sensitive to the inclusion of heterogeneity in price preferences, and this
is particularly evident in our daily model estimates of column 3. However, the implied
estimates of demand elasticities are somewhat less sensitive. We estimate median film-
level own-price elasticities of 3.91 and 1.72 for the daily (column 3) and weekly (column 6)
models, respectively. In (unreported) first stage regressions for our MNL model, our cheap
ticket indicator variable plays an important role, accounting for much of the variation in
price.
We include time-variant theatre-specific film variables relating to previews and opening
day sessions, and we include indicator variables (unreported) for each week of the run of
a film. Consistent with Davis (2006), Einav (2007), and Moul (2007), consumers prefer
to see a film earlier in its run with opening day being particularly attractive. Interest in
movie attendance declines approximately linearly with the week of the run, particularly for
the first 8 weeks of a movie’s run (which accounts for the bulk of our data). The numeraire
is a film running beyond week 10 of its release, and the Preview coefficient is consistent
with interest similar to a mid-run film. Academy Award nominations have a mixed
relationship with attendance, but the effect of a win is estimated to be negative. This is a
likely manifestation of the fact that the eventual winners had all spent considerable time
in cinemas prior to their wins.
28
Saturday followed by Sunday, followed by Friday are the most popular days, with
coefficients relative to a non-Friday weekday numeraire. Public and school holidays also
attract movie goers. Weather also plays a role, with rainy days and cooler days tending
to draw larger attendances. Turning to theatre characteristics, we see that location in
a shopping centre and the number of cinema screens (at the theatre location) are both
associated with greater attendance.
In the MNL model, the fact that the coefficient of ‘Pop[0,5]’ is substantially greater
than that of ‘Pop(5,10]’ is consistent with travel costs associated with cinema attendance
as in Davis (2006). Against a-priori expectations, we see that an increase in the median
age increases attendance, and consistent with a-priori expectations an increase in median
weekly income is associated with increased attendance, with these relationships being
26
In unreported OLS estimation, when price was not instrumented the price coefficient was found to
be in the region -0.15 to -0.17, i.e. less elastic in all specifications. This is consistent with expectations
given that price endogeneity creates an upward bias on the OLS estimator.
27
For example, Dewenter and Westermann (2005) find the own price elasticity of demand to be in the
range of 2.4-2.76 using annual German data between 1950 and 2002.
28
Notice that, while our specification of the dynamic path of attendance is quite flexible, it is still
restrictive: we impose the same dynamic pattern of attendance for all firms. Our results suggest that the
dynamic path of attendance is different for these successful films.
17
weaker or even negative at greater distances (i.e. 5 to 10 kilometres away). This suggests
that the demographic profile further away from a cinema has little direct bearing on
cinema performance. These observations are consistent with the existence of travel costs
in cinema attendance.
Table 6 presents coefficient estimates on time-invariant film characteristics. As we
might expect, there is a positive relationship between attendance and a film’s budget and
advertising spending (with the exception of our daily model allowing for price heterogene-
ity), while screening a film at a greater number of locations dilutes the audience at any
one theatre. Sequels, and films attracting favourable reviews are associated with larger
audiences. We observe a negative relationship between attendance and the presence of
stars in a film. A possible explanation is that the film’s budget and advertising already
controls for the appeal of marquee cast. Coefficients on our genre and ratings indicator
variables suggest that attendance is greater for comedies, action movies, and ‘M’ and ’PG’
rated movies, and is lower for dramas.
Consider next the parameters related to consumer heterogeneity in Table 5. Recall
that travel costs enter with a negative sign. In all specifications, the distance coefficient
is highly significant, but estimated to be quite small, particularly for the weekly spec-
ifications. Compared to the effect of a one dollar increase in ticket price, travelling an
additional kilometre to a movie venue appears a relatively minor imposition. This is
consistent with the idea that consumers decide first on the film they intend to see before
considering the most appropriate venue.
29
Heterogeneity in the constant term suggests
consumers differ in their propensity to substitute between movies rather than forego movie
attendance altogether. Columns 2 and 5 permit heterogeneity in preferences for opening
week films, and columns 3 and 6 allow, in addition, heterogeneity in preferences towards
price. We observe heterogeneity in preferences for opening offerings. However, for our
weekly models, the extent of heterogeneity identified is quite sensitive to specification
changes. We also identify heterogeneity in price sensitivity, but we found the magnitude
of this parameter to be relatively sensitive in alternative specifications we considered.
Finally, in each of these specifications, we also consider the relationship between cinema
attendance and local demographic characteristics. We do not find a consistent relation-
ship between attendance and the local proportion of young adults (those aged 15-30),
while we do find a positive relationship between log income and attendance.
As we presaged in Section 5.1, our empirical setting constrains our ability to identify
heterogeneity parameters and this led to sensitivity in our estimates. The restrictive na-
ture of price variation in our sample limited our ability to separately identify the mean
and variance of preferences for price.
30
The tendency of cinemas to coordinate the release
of new films hampered the identification of the random coefficient on opening week films.
Similar considerations led us to rule out more flexible specifications of consumer hetero-
29
Indeed, according to a Cinema and Video Industry Audience Research survey (conducted by the
Cinema Advertising Association) the majority of people decide which film to see in advance of their
visit (CAVIAR Consortium, 2000). An additional complication is that some movie goers may see movies
near their workplace rather than near their home. We calculate distances relative to the distribution of
residential rather than commercial locations.
30
For example, we note that, while the random coefficient on price is precisely estimated in the models
presented, this coefficient is quite sensitive to changes in specification. We have omitted other hetero-
geneity parameters for this reason.
18
geneity. For the results that follow, we focus attention on the random coefficients model
contained in columns 2 and 5. This specification allows heterogeneity over preferences for
opening week attendance but not over price.
6.1 Elasticities
Our demand estimates yield film-level median and mean elasticities of 3.34 and 3.13,
respectively, for the daily model, with a standard deviation of 0.45. Elasticities for the
weekly model are somewhat lower, with a median, mean, and standard deviation of 2.45,
2.30, and 0.33, respectively. These suggest that film-level demand is relatively elastic. At
the market level, estimated elasticities are lower but less than one. We obtain market-level
median elasticities for the daily and weekly models of 2.27 and 1.26, respectively.
Tables 7-10 detail a selection of demand elasticities, disaggregated by week of run and
by cinema.
31
Table 7 presents summary information on film-level own-price elasticities
for the daily and weekly models. The daily (weekly) model is presented in the columns on
the left (right). In the top panel, we show elasticities by the week of a movie’s run. Our
specification allows heterogeneity in preferences for opening week films, but does not ad-
mit additional heterogeneity over the life of a film. The variation in own-price elasticities
beyond week one of a film then stems from changes in the mix of films and cinemas con-
ditional on week. The bottom panel presents analogous information indexed by cinema.
We see a greater degree of variation in own-price elasticities, reflecting heterogeneity in
preferences across cinemas with different locations and local demographic conditions.
Table 8 presents median film-level cross-price elasticities by week of run. Estimates
for the daily (weekly) model are presented in the top (bottom) panel. The first two rows
and columns represent previews and opening days, with the remainder increasing in week
of run. Element (j, k) contains the median price elasticity of a film screening in week j 2
with respect to the price of a film screening in week k2. As we can see from the diagonal
for both market definitions, elasticities tend to fall with week of run as more consumers
switch to the outside good. The weekly market definition admits a larger set of substitute
products. The propensity to substitute to any specific product is then reduced, leading
to lower estimated cross-price elasticities for the weekly model.
Table 9 presents analogous information with cross-price elasticities disaggregated by
cinema. Again, we see predominantly lower elasticities in the weekly model, reflecting
the greater number of substitute products. The higher estimated travel costs of the daily
model are also reflected in the substitution patterns. We observe a greater sensitivity to
location in the daily model. In particular, cross-price elasticities for films within the same
cinema are markedly higher in the daily model, but not the weekly model.
Table 10 presents cinema-level cross-price elasticities. Diagonal elements represent
own-price elasticities, and off-diagonals contain cross-price elasticities. At the cinema
level, demand is still elastic, with own-price elasticities in the vicinity of 3 - 3.5 for most
cinemas in the daily model and in the range 2 - 2.5 for most cinemas in the weekly model.
This finding is consistent with our conjecture that the daily model may overstate the
extent of market expansion due to the daily model not permitting substitution between

19
days—by definition. Once we aggregate to the cinema level, we see noticeable substitution
across cinemas. In the daily model, the higher estimated travel cost parameter is again
reflected in elasticities that are more sensitive to location.
6.2 Market expansion or cannibalisation?
The effect of the entry of a new product into a market can be decomposed into a mar-
ket expansion effect (attracting new customers to the market), a market stealing effect
(poaching customers from rival firms), and cannibalisation (diverting customers from one
of your existing products to the new product). We could think of the effect of a decrease in
price in similar terms. In this section, we discuss the extent to which our estimates point
to a market expansion effect arising from the policy of cheap Tuesday cinema pricing.
More pertinently, we are interested in whether discount pricing has led to an expansion
in revenues.
The major source of price variation in our data set is the discounts offered on films
shown on Tuesdays at most theatres. Our daily model, by definition, does not permit
substitution across days; the only products in the consumer’s choice set are the movies of-
fered on a given day (and the outside good). Hence, when prices are lowered on Tuesdays,
the increase in consumption is at the expense of other movies shown on Tuesdays and the
outside good. With most movies receiving discounts on Tuesdays, the aggregate effect is a
decrease in the market share of the outside good; that is, a market expansion. In practice,
some consumers might substitute away from movie consumption on a Wednesday when
they decide to see a movie on a Tuesday. By ignoring this, our daily model overstates the
market expansion effect of a decrease in prices.
Our weekly market definition is designed to overcome this limitation. Our weekly
model incorporates in the choice set all films at all theatres showing in the week. Con-
sumers are therefore able to substitute between movies shown on different days of the
week. This opens up the possibility that the “cheap Tuesday” policy has led to substi-
tution away from other days in the week. In fact, in this specification, consumers see at
most a single movie over the week. That is, any consumer attending a movie on a Tues-
day cannot also attend on Wednesday. This specification may therefore also place too
much restriction on consumer behaviour. In practice, some consumers who are attracted
to cheap Tuesday movies may decide not to visit the cinema on other days in the week,
but some consumers may be willing to attend more than once in the week. Consequently,
our weekly market definition has the potential to overstate the degree of cannibalisation
and/or market stealing.
Because we are unable to account for all of the sources of preference heterogeneity
for movies, whether our weekly model overstates or understates the extent of market
expansion is ambiguous. In particular, we do not allow for heterogeneity in preference
towards the day of screening of a film. To see why this may be important, consider the
extreme case provided by the simple MNL with our weekly market definition. It is well
known that under the MNL, substitution patterns are driven by market shares: consumers
substitute to products in proportion to their market share. Consider the preferences of
a consumer contemplating seeing film f shown at theatre h on a Tuesday. In the weekly
model, also included in her choice set are film g shown at theatre h on a Tuesday and
20
film g shown at theatre h on a Wednesday. Her substitution patterns to either of these
films will be identical because they share the same characteristics (except possibly price)
and thus have the same market share. We may suspect that in practice consumers will be
more willing to substitute to films screening on the same day. The implications for our
estimates of the market expansion effect are ambiguous, but we have no reason to suspect
market expansion is substantially overestimated in our weekly model.
32
Both our daily and weekly models suggest that the effect of discounting policies on
Tuesdays has led to an increase in revenue. Demand elasticities are greater than 1 at
the film, cinema, and market level with both market definitions. In both specifications
the outside good has a large market share, and much of the substitution is away from
the outside good. In the next section, we examine the implications for profit-maximising
prices.
6.3 Revenue-maximising prices
In Table 11, we present revenue-maximising prices for a selection of cinemas based on our
demand estimates. We present results from both the daily and weekly models. Results
are based on a selection of cinemas for screenings taking place on January 4.
33
The first
column presents the actual price offered at a specific cinema. The left (right) hand side
of the table contains revenue-maximising prices for the daily (weekly) model. Revenue-
maximising prices are calculated for a range of ownership structures. Columns (1-4)
for each market definition present optimal prices based on cinema-level, circuit-level,
distributor-level, and market-level ownership, respectively. In each specification, revenue-
maximising prices are below actual prices. Optimal prices are higher for the weekly model,
consistent with our lower elasticity estimates for the weekly model. Optimal prices are
also higher for more concentrated market structures, with optimal prices under monopoly
ownership in the weekly model approaching the observed level of prices. Optimal prices at
the circuit level are similar but sometimes higher than at the distributor level, reflecting
greater concentration of ownership at the circuit level. Consequently, our results do not
suggest a substantial conflict between distributors and exhibitors.
Recall from the discussion in Section 3.2 that we implicitly impose two main assump-
tions: cinemas are capacity unconstrained, and concession sales do not enter the profit-
maximisation problem. Under these assumptions, optimal prices are quite low relative
to prevailing cinema prices. In light of this result, it is worth briefly interrogating our
maintained assumptions.
To investigate the importance of capacity constraints, we focus on a selection of our
data for which we have more detailed information. We have session time information
for the 13 largest multiplex cinemas in our sample over four complete weeks in April
2007.
34
This dataset comprises 21,206 session times covering 4,821 daily film-at-theatre
data points across 41 unique films, and represents approximately 3.3% of our full sample.
With screens (seats) ranging from 10 to 17 (1,980 to 4,112), these cinemas are larger than
average in our dataset. The average seats-per-screen at these 13 locations ranges from

Results are not sensitive to our particular selection of cinemas and date.
34
Session time information was collected from old newspapers using an optical reader.
21
168 to 270, with the average cinema screen among these catering for 217. We calculate
average daily capacity for a film-at-theatre by multiplying the average seats-per-screen
by the average number of daily screenings-per-film. On average each film screened 4.4
times per day with a standard deviation of 2.48. Naturally, new release and more popular
films tend to be allocated a greater number of sessions each day. Restricting attention to
opening week films, the average number of daily sessions increased to 5.37. A number of
popular films had significantly more screenings than this average. For example, the film
300 occupied 15 sessions per day in its opening week at two locations. Accordingly, we
consider further subsets of our data contingent upon national opening week screen count.
Conditioning in this manner we observe average (opening week) daily sessions for films
opening on more than 200 and 300 screens as 7.38 and 8.95, respectively, which would be
regarded as a large (wide) release in the Australian industry.
35
This capacity information is contained in the far right column of Table 12.
36
The
remaining columns contain information about actual and simulated attendance for our
April selection of cinemas and films. Columns from left to right contain, respectively,
information based on actual attendance, model simulated attendance based on actual
prices, and model simulated attendances based on cinema-, circuit-, distributor-, and
market-based revenue maximisation. The top (bottom) panel contains information based
on our daily (weekly) model. Rows contain information about different cuts of this data:
the first row uses this full dataset; the second row restricts attention to films in their
opening week; and the next two rows, respectively, further restrict attention to films
opening on more than 200 and 300 screens nationally.
37
The first row (“All Sessions”) of each panel suggests that there is substantial excess
capacity on average in the data. Further, our model simulations suggest excess capacity
for a sizeable selection of screenings even if cinemas were to substantially reduce prices.
However, once we restrict our attention to more popular films, capacity constraints start
to bind. Taken together, these results paint a picture of an industry with substantial
excess capacity for the vast majority of screenings, but with binding capacity constraints
for a small selection of screenings.
We are unable to bring direct evidence to our second maintained assumption; that
cinema managers do not consider concession sales. If concession sales are positively related
to attendance (as we would expect), then our results place an upper bound on optimal
prices for the vast majority of sessions which are anticipated to be capacity unconstrained.
This suggests non-trivial gains from deviating from the practice of uniform pricing across
films.
35
Across the full sample of 314 films, opening screens above 200 and 300 represent approximately the
75th and 85th percentiles, respectively, of this variable.
36
We do, of course, realise that cinema operators manage with-in theatre auditoria as well as number
of sessions during the course of a film’s run but do not attempt to integrate this into our exercise. Given
the likely allocation of larger capacity auditoria for new films, this would subsequently increase capacity
even further than our estimates.
37
Note that these sample selections are based only on (a minimal set of) observable information for
cinema managers. The week of a film’s run is clearly an important determinant of attendance, while the
number of opening week screens will be related to the industry’s forecast of attendance.
22
7 Conclusion
In this paper, we develop a random coefficients discrete choice model of cinema demand
using a large sample of daily film-at-theatre box office revenues from the Sydney region
over the 365 days of 2007. With price uniformity across film and session a common feature
of movie markets, a critical component of our identification strategy derives from the
cheap Tuesday ticket prices which characterise the Sydney market. We find an intuitive
relationship between attendance and a range of characteristics which relate to the film,
theatre, and timing of consumption.
We find that movie demand is price elastic. This suggests that the “cheap Tuesday”
discounting experiment has been successful at raising revenue. This conclusion survives
several robustness checks. Elasticities are greater than one at the film-, cinema-, and
market-level. This result holds both using our daily market definition in which substitu-
tion across days of the week is not permitted, and using our weekly market definition in
which such substitution is mandated.
Our results imply that cinemas could increase profits by offering more off-peak pricing,
and by employing variable film pricing practices. This doesn’t necessarily imply that the
pricing strategy should be particularly complex it could be as simple as categorising
certain films as ‘blockbusters’, or offering a ‘new release’ and ‘old release’ price contingent
upon some (commonly known and pre-specified) week of the run. For example, our
simulations suggest mid-run films could be discounted without running into screening
capacity constraints.

Appendix
In this appendix, we provide additional detail on our demand estimation algorithm. Much
of the material is drawn from Berry et al. (1995) and Nevo (2000, 2001), where additional
discussion can be found. We break the demand estimation details into several components.
We first outline the calculation of the GMM objective function for a given parameter
vector. Next, we discuss the gradient of the vector of moment conditions, required both for
the application of gradient-based optimisation algorithms, and the calculation of standard
errors. We also outline the calculation of the variance-covariance matrix of the objective
function.
First, let us briefly introduce some additional notation. Let J =

the number pertaining to
period t. We define S to be the J ×1 vector of observed market shares and S
.t
the J
t
×1
vector of observed period t market shares. Similarly, s(x, p, L, ξ; θ) is the J × 1 vector
of predicted market shares from our model, and ˜s(τ, x, p, L, ξ; θ) is the J × NS matrix
of purchase probabilities of NS simulated individuals drawn from P
(L, D, ν). Following
Nevo (2001), we partition the parameter vector into two components, θ = (θ
1
, θ
2
). An
important interim step in estimation is the calculation of the vector of mean values, δ.
Given S, the parameter vector θ
2
= (λ, Π, Σ) enters δ = δ(S, θ
2
) in a nonlinear manner.
By contrast, the vector θ
1
= (α, β) can be extracted as a linear function of δ(S, θ
2
).
The GMM objective function
Calculating the GMM objective function, G(θ), involves several steps:
1. given the vector of non-linear parameters, θ
2
, and a vector of observed market shares,
S, solve for the vector of mean values (defined below) of each product, δ(S, θ
2
);
2. given θ
2
and δ(S, θ
2
), solve for the vector of linear parameters, θ
1
;
3. calculate the moment conditions, ˆg
1
(θ) and ˆg
2
(θ), and the GMM objective function,
G(θ).
We decompose the indirect utility enjoyed by consumer i by attending film f

Our first exercise is to calculate δ, which is implicitly defined by the relationship
s

(δ

. (16)
26
In turn, we calculate the market share vector, s, by aggregating over the individual
purchase probabilities of consumers. We simulate NS consumers, with consumer i’s
characteristics (L

, D

, ν
i
) drawn from P
(L, D, ν). The purchase probabilities of consumer

assumption that our two sets of moment conditions, g

Given the vector of mean utilities, δ(S, θ

Our method for dealing with our film fixed effects follows Nevo (2001). We proceed in
two stages. First, we obtain our GMM estimator,
ˆ
θ, by minimising G(θ) using equation
(24). This requires removing from x any explanatory variables that are specific to each
film and time invariant, and including a set of film indicator variables. We then perform an
auxiliary regression of our film-fixed explanatory variables on the estimated fixed effects,
