Revenue Sharing and Vertical Control in the Video Rental Industry

Revenue sharing contracts, in which retailers pay a royalty on sales to their suppliers, are now widely used in the video rental industry. We show that revenue sharing is valuable in vertically separated industries in which demand is either stochastic (unpredictable) or variable (e.g., systematically declining), downstream inventory is chosen before demand is realized and downstream firms engage in intrabrand competition. Unlike two-part tariffs, revenue sharing achieves the first best outcome by softening retail price competition without distorting retailers' inventory decisions. Our theories are also consistent with trends in prices and availability following retailers' adoption of revenue sharing contracts.     

The U.S. Motion Pictures Industry: An Empirical Approach

We hypothesize that the U.S. motion pictures industry is structured so that star presence increases box office receipts and (less so) admissions, but places Ricardian limits on the output of blockbusters. The few dominant studios (majors) rely on a modified star system to generate supra-normal box office by stimulating admissions at exhibitors. Rising costs (from stars and their promotion) are required for rising revenues; that is, the majors gain revenue only at higher costs. Although the industry has unique features, the empirical results are surprisingly relevant to other industries.     

Determinants of the ARM share of national and regional lending

We model the ARM share of mortgage lending and provide several unique contributions to the mortgage choice literature. First, we motivate the use of the price spread between fixed- and adjustable-rate credit as a regressor by constraining the effect of FRM and ARM prices to be symmetric and show that the data support this restriction. Second, our data span a far longer time period (six years) than previous research. Third, we estimate separate share equations by region, allowing us to contrast geographic variation in ARM shares. Fourth, we examine the effect of convertible ARMs—which became prevalent in mid-1987—on overall ARM lending.     

The impact of jump risks on nominal interest rates and foreign exchange rates

This article investigates the relationship between the nominal interest rate and inflation and also the forward exchange rate under a general specification of the underlying processes govering the foreign exchange rate. There are three distinct risks that affect the relation between the real rate of interest and the nominal rate namely, consumption risk, diffusion risk, and the existence of jump risks of inflation. Jump risks lower the nominal interest rate because of jump hedging of a nominal bond. The forward exchange rate depends on the expected depreciation of the domestic currency as well as these three risks. As the domestic jump risks increase, the domestic nominal interest rate decreases and the forward exchange rate decreases.     

CAPITAL CHOICES: CHANGING THE WAY AMERICA INVESTS IN INDUSTRY

The Project on Capital Choices, sponsored by the Harvard Business School and the Council on Competitiveness, initially set out to determine the extent to which the competitiveness of American industry is being undermined by a short time horizon. The project has since evolved into a broader examination of how private capital is allocated in the United States, Japan, and Germany and an assessment of the relative effectiveness of the American corporate governance system. Eighteen research papers were prepared by 25 prominent scholars in a wide range of disciplines. Professor Porter's paper, from which the following article is excerpted, develops an overall framework for understanding national investment systems and their consequences, drawing on the project papers and his own research. The complete paper is available through the Council on Competitiveness. A book containing all the project papers will be published by the Harvard Business School Press.     

A note on weekday, intraday, and overnight patterns in the interbank foreign exchange and listed currency options markets

Transactions data are used to investigate returns patterns for close-to-close, close-to-open, and intraday long positions in spot currency (interbank) and currency put options (listed) for the years 1983 through 1988. Both trading-day and calendar-day hypotheses are investigated. Under the former, spot market returns are found to be significantly higher from Friday close to Monday close and from Friday close to Monday open. Under the calendar-day hypothesis, however, no significant close-to-close pattern emerges, and the Friday close to Monday open effect is reversed. Finally, spot (put) market returns are found to be significantly lower (higher) for Tuesday and Friday afternoons.     

Seasonal Variation in Cost-of-Funds at Thrift Institutions

The purpose of this note is threefold. First, in addition to the well-known seasonal pattern to the eleventh-district cost-of-funds (COF), we document a twelve-month seasonal in the national median COF. Second, we demonstrate that the cause of seasonality in each of these COF series is due to the maladjustment of length-of-month effects. In particular, the eleventh-district COF is biased upwards in relatively short months while the national median is biased downward. Third, we show that the popular partial adjustment model for modeling the COF is misspecified.     

Taxation,imperfect competition,and discontinuities

Most work on taxation assumes that market adjustments to taxation will be small and continuous and so analyzes the effects of taxation using standard marginal methods. However, the world often changes in large and discontinuous ways. This paper looks at the effects of taxation when discontinuities in market adjustments are allowed because market structure is determined endogenously by the discrete entry and exit decisions of firms. The results indicate that the potential for discontinuities generates tax effects that are considerably different from those that emerge when adjustments are small and continuous. With discontinuities, taxes can have large and discrete effects, for example, by increasing prices far in excess of the tax itself or by changing utility in a highly nonmarginal way. Of more significance, with discontinuities taxes can actually increase welfare even when they lessen competition and raise prices. Taxes can also have markedly different effects on the income and welfare of different groups. Consumers are always made worse off by a tax, but a tax may be supported by the firms in an industry if the tax limits entry and thereby increases firm profits.
