DVD sales and the R-rating puzzle

In the last decade, attendance at movie theaters has been relatively stagnant, while sales of digital versatile discs (DVDs) have grown dramatically. In this paper, we look at the factors determining sales of individual DVDs in the United States. Using data on new motion pictures released on DVD between 2006 and 2008, we find the demand for new DVDs is price-inelastic and that DVD sales are counter-cyclical. We find that previous box office success has strong positive effects on DVD sales. Production budget also has a positive effect on DVD sales, albeit indirectly through its effect on box office revenues. Critical acclaim has significant positive effects on both box office revenue and DVD sales, but the effect is smaller in regard to DVDs. There is some evidence to suggest that DVD sales are higher for movies with more sexual content and more violent content and lower for movies with more profanity, but these effects are indirect through the changes in the box office of these movies. We find that sales of R-rated DVDs are not as dependent upon critical acclaim as movies of other ratings, and are thus less risky for movie studios to produce. Our findings provide another explanation for the R-rating puzzle.
