Price Discrimination and Copyright Law: Evidence from the Introduction of DVDs

This paper examines the welfare effects of intellectual property protection, accounting for firms’ optimal responses to legal environments. I examine firms’ use of indirect price discrimination in response to U. S. copyright law preventing direct price discrimination. Using data covering VHS and DVD movie distribution, I explain studios’ optimal pricing strategies under U. S. copyright law, and determine optimal pricing strategies under E. U. copyright law, which allows for direct price discrimination. I find that studios’ use of indirect price discrimination benefits consumers and harms retailers. Optimal pricing under E. U. copyright law further benefits studios and consumers. I also reanalyze these issues assuming continued DVD adoption.

Price Discrimination, Copyright Law, and Technological Innovation: Evidence from the Introduction of DVDs

This paper examines the welfare effects of intellectual property protection, accounting for firms' optimal responses to legal environments and technological innovation. I examine firms' use of indirect price discrimination in response to U.S. copyright law, which effectively prevents direct price discrimination. Using data covering VHS and DVD movie distribution, I explain studios' optimal pricing strategies under U.S. copyright law, and determine optimal pricing strategies under E.U. copyright law, which allows for direct price discrimination. I analyze these optimal pricing strategies for both the existing VHS technology and the new digital DVD technology. I find that studios' use of indirect price discrimination under US copyright law benefits consumers and harms retailers. Optimal pricing under E.U. copyright law also tends to benefit studios and consumers. I also reanalyze these issues assuming continued DVD adoption.

The Effects of Revenue-Sharing Contracts on Welfare in Vertically-Separated Markets: Evidence from the Video Rental Industry

In this study I analyze the implications of contractual innovation in vertically-separated industries, using the example of the video rental industry. Prior to 1998, video stores obtained inventory from movie distributors using simple linear pricing contracts. In 1998, revenue-sharing contracts, which include inventory restrictions, were widely adopted. I investigate the effect of using revenue-sharing contracts on firms' profits and consumer welfare, relative to linear pricing contracts. I analyze a new panel dataset of home video retailers that includes information on individual retailers' contract and inventory choices, weekly rentals and sales, and contract terms (prices and quantity restrictions) for 1,114 movie titles and 6,594 retailers in the U. S during each week of 1998 and 1999. A structural econometric model of firms' behavior is developed and estimated, and counterfactual experiments are performed. The results indicate that total upstream and downstream profits increase by three to six percent, and consumers benefit substantially when revenue-sharing contracts are adopted. I also examine the effects of the observed quantity restrictions. I find that these restrictions serve to increase profit for upstream firms and decrease profits for downstream firms, relative to revenue-sharing contracts without inventory restrictions.

The Effects of Capacity on Sales Under Alternative Vertical Contracts

Retailer capacity decisions can impact sales for products by affecting, for example, availability and visibility. Using data from the U.S. video rental industry, we report estimates of the effect of capacity on sales. New monitoring technologies facilitated new supply contracts in this industry, which lowered the upfront costs of capacity and required minimum capacity purchases, strongly impacting stocking decisions. Under the traditional supply contract, capacity costs $44 per tape (avg) and the marginal tape produces 10.4 to 18.0 additional rentals. Under the new contract, capacity costs$7 per tape (avg) and the marginal tape produces 0 to 4.9 additional rentals.

Effects of Product Availability: Experimental Evidence

Product availability impacts many industries such as transportation, events, and retail, yet little empirical evidence documents the importance of stocking decisions for firm profits, vertical relationships, or consumers. We conduct several experiments, exogenously removing top-selling products from a set of vending machines and analyzing substitution patterns and profit impacts of the changed product availability using nonparametric analyses and structural demand estimation. We find substantial switching to alternate products, and evidence of misaligned incentives between upstream and downstream firms in the choice of which products to carry. We discuss the trade-offs of both empirical approaches for analyzing product availability effects generally.

Analyzing the Welfare Impacts of Full-line Forcing Contracts

Theoretical investigations have examined both anti-competitive and efficiency-inducing rationales for vertical bundling, making empirical evidence important to understanding its welfare implications. We use an extensive dataset on full-line forcing contracts between movie distributors and video retailers to empirically measure the impact of vertical bundling on welfare. We identify and measure three primary effects of fullline forcing contracts: market coverage, leverage, and efficiency. We find that bundling increases market coverage and efficiency, but has little impact on one distributor gaining leverage over another. As a result, we estimate that full-line forcing contracts increased consumer and producer surplus in this application.

The Use of Full-line Forcing Contracts in the Video Rental Industry

We provide an empirical study of bundling in a supply chain, referred to as fullline forcing. We use an extensive dataset on contracts between video retailers and movie distributors to analyze the choices made on both sides of the market: which distributors offer full-line forcing contracts, which retailers take them up, and whether their decisions are profitable. Most large distributors offer full-line forcing contracts in our data. Our simulations indicate that their choices of which contracts to offer are profit-maximizing. However, many retailers prefer to utilize linear pricing contracts even when our model indicates that this may not be profit-maximizing.

Predicting the Efficacy of Future Training Programs Using Past Experiences

We investigate the problem of predicting the average effect of a new training program using experiences with previous implementations. There are two principal complications in doing so. First, the population in which the new program will be implemented may differ from the population in which the old program was implemented. Second, the two programs may differ in the mix of their components. With sufficient detail on characteristics of the two populations and sufficient overlap in their distributions, one may be able to adjust for differences due to the first complication. Dealing with the second difficulty requires data on the exact treatments the individuals received. However even in the presence of differences in the mix of components across training programs comparisons of controls in both populations who were excluded from participating in any of the programs should not be affected. To investigate the empirical importance of these issues, we compare four job training pro-grams implemented in the mid-eighties in different parts of the U.S. We find that adjusting for pre-training earnings and individual characteristics removes most of the differences between control units, but that even after such adjustments, post-training earnings for trainees are not comparable. We surmise that differences in treatment components across training programs are the likely cause, and that more details on the specific services provided by these programs are necessary to predict the effect of future programs. We also conclude that effect heterogeneity, it is essential, even in experimental evaluations of training programs record pre-training earnings and individual characteristics in order to render the extrapolation of the results to different locations more credible.

Creating Tourism Employment Opportunities for the Topnaar in the Namib Sand Sea

Our project created a plan to employ Topnaar community members in tourism activities at the Namib Sand Sea World Heritage Site. Our team determined that the creation of a Topnaar community tourism association would improve communication between the community and tour operators, thus facilitating Topnaar employment. The Topnaar are interested in developing community-based tourism activities and we identified a number of cultural and ecological attractions that appeal to both the Topnaar and tour operators. The village of Utuseb and the Lauberville campsite are two potential hubs for these tourism activities. The proposed tourism association will facilitate joint tourism efforts between tour operators and the Topnaar to ensure benefits to the entire community
