ABSTRACT
This article examines how quality affects heterogeneous multiple-product firms’ exporting behaviours. We develop a structural model of the global movie market, including both consumers’ movie demand choices and firms’ exporting decisions. A movie studio is a multi-product firm that releases many movies within a year. We model movie quality as a combination of firm-level appeal and product-level attractiveness. We find that both studio-level and movie-level heterogeneity affect demand for movie, and movie-level heterogeneity is relatively more important. We also explore the counterfactual effects of quality improvement and trade liberalization on trade. Our results show that improvement of quality increases both intensive margin and extensive margin of trade. By elimination of quota, we find that trade liberalization increases movie exports to a foreign market by 19%. The results of our study can also help improve understanding of trade in the service industry. For instance, we do not find a positive correlation between the foreign entry costs and the geographic distance, as in the case of manufacture goods.

Notes
1 These values are computed based on the average box-office of $2,186,283 for a movie in our dataset.
2 Abramitzky and Sin (Citation2014) take advantage of the fall of communism in Eastern Europe as a ‘natural experiment’ and estimate the extent to which communism slowed the trade in book translations using data from UNESCO’s Index Translationum. Ferreira and Waldfogel (Citation2013) study trade in popular music.
3 We follow the standard setup in the discrete choice model literature (Berry Citation1994).
4 The choice of these variables is based on the literature of movie demand (Ainslie, Drèze, and Zufryden Citation2005; Eliashberg, Elberse, and Leenders Citation2006; Einav Citation2007; Moul Citation2007). A sequel is a movie that continues the story of some earlier work.
5 Hanson and Xiang (Citation2011) also mentioned that the popularity of a movie depends on the ‘ability’ of its studio. But in their model, each firm produces a single variety, as in the work by Melitz (Citation2003).
6 This pricing practice is called the uniform pricing puzzle in the movie exhibition market (Orbach and Einav Citation2007). The only exception is 3D movies, which is a few more dollars than the regular movie price.
7 In the rest of this section, we suppress the time subscript but note that all our specifications have year fixed effects.

9 Budget data are also reported at BoxOfficeMojo.com and IMBD. But both data sources report production budget information for only a subset of movies.
