An Analysis of the Out-of-Market Gap for DVDs in the U.S.

We examine the out-of-market gap – the time between the end of a film’s theatrical run and its release on DVD – for a sample of U.S. films during 1988-2005. The average gap declined from 58.14 days in 1998 to 27.93 days in 2005; by 2005, 39% of the films were released on DVD prior to leaving the theaters. Probit and hazard models are estimated to explore the factors that influence a distributor’s decision to release a film on DVD before it exits the theaters, and the timing of the release for films that appear on DVD after they leave the theaters.      

Homogeneity and endogeneity in systems of demand equations

In estimating systems of demand equations one of the right-hand-side explanatory variables, expenditure, may be endogenous in the sense that it is correlated with the equation error. If the assumption of homogeneity of degree zero in prices and nominal income is imposed on the system, it turns out it is still possible to estimate the parameters of the system even when expenditure is endogenous. The estimation procedure is simple requiring just one additional ordinary least squares regression.The paper also demostrates that a model in which homogeneity is tested with expenditure assumed exogenous is exactly equivalent to a model in which the exogeneity of expenditure is tested with homogeneity imposed. Previous tests of demand systems which have rejected the homogeneity postulate might therefore be reinterpreted instead as rejecting the hypothesis of exogeneity of expenditure with homogeneity of degree zero in prices and nominal income taken as given.     

The Success of American Communes

This study analyzes the effect of the structure of communes on their success, using the data of 281 communes started in America from 1683 to 1937. Factors increasing the likelihood of success include (i) being a pietist religious sect, (ii) inducing commitment as measured by an index of several underlying variables, (iii) allowing some private property, and (iv) with some qualification, having anarchic governance. These results support the prevailing commitment hypothesis. They additionally indicate that communes can increase their likelihood of success by making some concessions to egoistic concerns.     

Test validation from a conceptual and legal perspective: Issues and trends

A little-explored issue in the psychological and legal literature involves test validation. This article discusses issues of test validation from both psychological and legal perspectives. Areas of inconsistency are noted and probable future directions are high-lighted.     

Government Failure in Urban Transportation

This paper assesses governmental performance in its investment, provision and regulation of urban transportation. Attention is given to public bus and rail transit and road transportation. Evidence based on urban transport in US cities reveals substantial allocative and technical inefficiencies that have led to large public transit deficits and severe highway congestion. I argue that it is futile to expect public officials to remedy the situation by pursuing more efficient policies such as congestion pricing and weighing costs and benefits when deciding transit service. The problem is that urban transportation policy is largely shaped by entrenched political forces that inhibit constructive change. The only realistic way to improve the system is to shield it from those influences and expose it to market forces by privatising it. This position is supported by empirical evidence based on simulations for the US and the UK's early experience with privatisation.     

Actual Share Reacquisitions in Open-Market Repurchase Programs

Unlike Dutch auction repurchases and tender offers, open-market repurchase programs do not precommit firms to acquire a specified number of shares. In a sample of 450 programs from 1981 to 1990, firms on average acquire 74 to 82 percent of the shares announced as repurchase targets within three years of the repurchase announcement. We find that share repurchases are negatively related to prior stock price performance, suggesting that firms increase their purchasing depending on its degree of perceived undervaluation. In addition, repurchases are positively related to levels of cash flow, which is consistent with liquidity arguments.     

Texas treasury notes and market manipulation, 1837-1842

This paper examines the course of the value of the paper money issued by the Republic of Texas in New Orleans, from 1837 to 1842, using a newly-constructed weekly time series of quotations, and focusing on the possibility of market manipulation. Specifically, during 1841, misleading information concerning a possible foreign loan reached New Orleans three different times. The first time, the information substantially raised the value of Texas Treasury Notes. The second time, the information raised the value, but to a lesser extent. The third time, the information had no impact.
