PATENT LENGTH AND THE TIMING OF INNOVATIVE ACTIVITY

The standard result in patent policy, as demonstrated by Gilbert and Shapiro (1990), is that infinitely lived but very narrow patents are optimal as deadweight losses are minimised and spread through time but inventors can still recover their R&D expenditures. By extending their innovative environment to include timing as an important choice, we demonstrate that a finitely lived, but broader, patent can be socially desirable. This is because a patent breadth is a better instrument than length to encourage socially optimal timing. Thus, patents need not be infinitely long in order to encourage a greater number of inventions     

ENDANGERED SPECIES CONSERVATION ON PRIVATE LAND

This paper analyzes the effect of alternative institutional arrangements on the conservation of endangered species and economic activity on private land. Because a landowner does not capture the full value of species conservation, her preferences on land use will not coincide with social preferences. Under current law, the landowner has incentives to invest in lowering conservation value and to deny access to regulators in order to prevent collection of information. Paying compensation corrects many of these perverse incentives. An alternative approach is to limit the ability of landowners to affect the regulatory outcome. Whether it is better to entice landowners to make socially efficient decisions by paying compensation or to limit the ability of landowners to affect outcomes through changes in the regulatory regime depends on both practical implementation difficulties and distributive justice considerations.     

What Factors Lead Management to Support or Oppose Employee Participation—With and Without Works Councils? Hypotheses and Evidence from Germany

This paper provides the first econometric analysis to distinguish between works councils in establishments where managers have a positive or negative view toward employee involvement in decision making. We similarly distinguish between establishments where no council is present in which management supports or does not support worker participation. We stress the potential role of works councils and participation in motivating employees. Our theoretical analysis and empirical results from German manufacturing establishment data show that the structure of the workforce, principal‐agent problems between owners and managers, collective bargaining, direct employee involvement, human resource management practices, and market strategy and innovativeness all play important roles. Some conflicting conclusions in the works council literature may be due to the failure to distinguish among industrial relations participation regimes characterized by cooperative or uncooperative relationships between works councils and management.     

What Works at Work: Overview and Assessment

This article discusses why it is difficult to measure the effects of management practices on organizational performance. In spite of these difficulties, a collage of evidence suggests that innovative workplace practices can increase performance, primarily through the use of systems of related practices that enhance worker participation, make work design less rigid, and decentralize managerial tasks. A majority of U.S. businesses have adopted some innovative work practices. However, only a small percentage of businesses have adopted a full system of innovative practices. We outline several constraints on the diffusion of new work practices, and suggest directions for future research     

Testing Market Efficiency: Evidence From The NFL Sports Betting Market

This article examines the efficiency of the National Football League (NFL) betting market. The standard ordinary least squares (OLS) regression methodology is replaced by a probit model. This circumvents potential econometric problems, and allows us to implement more sophisticated betting strategies where bets are placed only when there is a relatively high probability of success. In-sample tests indicate that probit-based betting strategies generate statistically significant profits. Whereas the profitability of a number of these betting strategies is confirmed by out-of-sample testing, there is some inconsistency among the remaining out-of-sample predictions. Our results also suggest that widely documented inefficiencies in this market tend to dissipate over time.     

ECONOMIC MODELING AND THE FALSE TRADEOFF BETWEEN ENVIRONMENTAL PROTECTION AND ECONOMIC GROWTH

One important element of the current policy debate on what measures should be taken to reduce greenhouse gas emissions is the controversy over the costs of reducing those emissions. "Top-down" macroeconomic and general equilibrium models give much higher estimates of the costs than "bottom-up" models based on microeconomic and engineering data. This paper investigates the causes of the divergence between the two modeling approaches. The conventional top-down models incorporate strong implicit assumptions about maximization, technical progress, and organizational efficiency that predetermine their results. However, these assumptions are questionable on both theoretical and empirical grounds. Economic assessment of policy alternatives would benefit. from analyses that take account of the actual characteristics of business firms and other organizations that emit greenhouse gases in the course of their activities.     

Cross-Quarter Differences in Stock Price Responses to Earnings Announcements: Fourth-Quarter and Seasonality Influences*

Abstract. This article examines the impact of one form of sales seasonality on the response of equity returns to earnings announcements in different quarters. We regress unexpected announcement period returns on unexpected earnings and compare the results for seasonal firms—those with sales consistently concentrated in the same quarter each year—to those of other firms. For seasonal firms, we find robust evidence of a greater regression intercept and some evidence of a greater earnings response coefficient in peak sales quarters than in nonpeak quarters. These results are consistent with a greater resolution of the uncertainty about seasonal firms' prospects in their peak sales quarters than in other quarters. Our evidence also shows that fourth-quarter earnings announcements have smaller stock price response coefficients than do interim announcements. Some prior has found smaller fourth-quarter earnings response coefficients for small but not large firms. We find some evidence that fourth-quarter earnings response coefficients are smaller than interim-quarter response coefficients for large firms as well as for small firms. This suggests that explanations for smaller fourth-quarter earnings response coefficients need to be applicable to both large and small firms. Résumé. Les auteurs examinent, pour différents trimestres, l'incidence d'une forme de caractère saisonnier des ventes sur la réaction du rendement des actions aux déclarations de bénéfices. Ils effectuent une analyse de régression des rendements imprévus des trimestres par rapport aux bénéfices imprévus et comparent les résultats obtenus dans le cas des entreprises dont les activités sont saisonnières—c'est-à-dire dont les ventes sont systématiquement concentrées dans le même trimestre chaque année—aux résultats obtenus dans le cas des autres entreprises. Dans le cas des entreprises dont les activités sont saisonnières, les résultats de l'analyse démontrent vigoureusement que l'intersection de la régression est supérieure et confirment avec moins de fermeté que le coefficient de réaction aux bénéfices déclarés est supérieur pour les trimestres où le volume des ventes culmine, par rapport aux autres trimestres. Ces résultats permettent de conclure à une plus grande résorption de l'incertitude relative aux perspectives des entreprises dont les activités ont un caractère saisonnier dans les trimestres où les ventes de ces entreprises culminent que dans les autres trimestres. Les résultats de l'analyse démontrent également que les déclarations de bénéfices au quatrième trimestre donnent lieu à des coefficients plus faibles de réaction du cours des actions que les déclarations des trimestres intermédiaires. Certains travaux antérieurs ont établi que les coefficients de réaction aux déclarations de bénéfices du quatrième trimestre étaient plus faibles pour les petites entreprises que pour les grandes. L'analyse des auteurs tend ici à démontrer que les coefficients de réaction aux déclarations de bénéfices du quatrième trimestre sont plus faibles que les coefficients de réaction des trimestres intermédiaires pour les grandes entreprises aussi bien que pour les petites entreprises. Ces constatations donnent à penser que les facteurs qui expliquent les coefficients de réaction plus faibles aux déclarations de bénéfices du quatrième trimestre devraient pouvoir s'appliquer tant aux grandes qu'aux petites entreprises.     

TAX REFORM

After brief individual presentations, panelists discuss among themselves and with the audience a broad spectrum of issues regarding various taxes and tax reform proposals. The discussion includes such issues as privatizing Social Security and Medicare, eliminating income tax withholding, and the merits and demerits of income taxes, consumption taxes, value added taxes, sales taxes, and taxes on resources that have an inelastic supply. One panelist relates his recent experiences using his tools as an economist to deal with tax and related issues as a current member of the Canadian Parliament. Another cites practical problems of implementing tax reform from his long experience advising governments, especially in Latin America. A major focus of the exchange of views is on public choice problems involved in passing and implementing a so-called flat tax. However, the discussion also deals with economic efficiency and equity considerations and with nearly all other types of taxes. The discussion includes not only the impact on the country within which tax reform occurs, but international implications, as well.
