This paper introduces a novel consumption-based variable, cyclical consumption, and examines its predictive properties for stock returns. Future expected stock returns are high (low) when aggregate consumption falls (rises) relative to its trend and marginal utility from current consumption is high (low). We show that the empirical evidence ties consumption decisions of agents to time variation in returns in a manner consistent with asset pricing models based on external habit formation. The predictive power of cyclical consumption is not confined to bad times and subsumes the predictability of many popular forecasting variables.  相似文献

The purpose of this research was to investigate the efficiency of laundering at low and recommended water temperatures using a heavy-duty biological detergent and a low-temperature detergent. The effectiveness of the process was measured in terms of the degree of stain/soil removal from laundered garments, and in the removal and transfer of bacteria from infected test pieces. The results indicate that with both detergents a reduction in washing efficiency occurs as the temperature of laundering is decreased, except when the difference between the recommended and low water temperature is small. Evidence was also obtained that shows that reducing wash temperatures decreases the degree of disinfection and increases the cross-infection of articles washed in the same load.  相似文献

Determining the appropriate degree of protection to provide intellectual property in the United States and abroad is an important public policy issue. This paper addresses the role of intellectual property protection in the firm's decision on the level of investment in research and development. It also focuses on the stimulus that such protection provides for economic growth in both developed and developing countries. The main conclusion is that the benefits of designing and enforcing a mechanism for strong protection of intellectual property generally exceed the costs.  相似文献

In applying economic theory to evaluate antitrust laws, Judge Robert Bork explicitly favors a partial equilibrium over a general equilibrium approach. He believes the general model assumes away too many real-world aspects to be usefully employed as a criterion by which to judge real-world laws.
However, Bork's partial equilibrium replacement, the Oliver Williamson trade-off model, implicitly contains many of the same assumptions as general equilibrium theory. Equilibrium prices in all industries, an absence of external effects, and well-defined demand curves are assumptions of both general equilibrium theory and the Williamson trade-off model. If one theory is judged inadequate because of these assumptions, so should the other.
Bork's analysis is more consistent with market process theory than with his own partial equilibrium approach. Market process theory assumes neither the absence of externalities, nor the presence of well-defined demand and equilibrium prices in all industries.  相似文献

This paper examines two forces that may soon increase competition in the U.S. secondary conforming mortgage market: (1) the Federal Home Loan Bank mortgage purchase programs, and (2) the adoption of revised risk-based capital requirements for large U.S. banks (Basel II). We argue that this competition is likely to reduce the growth and relative importance of Fannie Mae and Freddie Mac and hence reduce their charter values and effective capital. Such developments could, in turn, lead to more risky behaviors by these two companies. This last consequence warrants greater supervisory awareness and legal authorities.  相似文献

We analyze personal open market trades by managers around stock repurchases by tender offer. With the exception of Dutch auction offers, managers trade their firm's shares prior to repurchase announcements as though repurchases convey favorable inside information to outsiders. Prior to fixed price repurchase offers that do not follow takeover-related events, managers increase their buying and reduce their selling of their firm's shares. Prior to repurchases that follow takeover-related events, only a decrease in selling is found. No abnormal trading precedes Dutch auction repurchase offers.  相似文献

Abstract. This paper examines the probability judgments made by auditors for their financial statement footnote disclosure decisions and their audit report additional paragraph decisions in the presence of material loss contingencies. In the United States these judgments are governed by SFAS No. 5 and SAS No. 58. Two prior studies have reported inconsistent results pertaining to the degree of compliance of auditors with the judgment and decision-making process implied by SFAS No. 5. In contrast, SAS No. 58 has not previously been examined with respect to auditor compliance. Results from an experiment with 64 audit partners from six firms were consistent with the hypothesis that audit partners employ the same (compensatory) judgment process when making footnote disclosure decisions as when making additional paragraph decisions. This process led the partners to make judgments for the additional paragraph decision that were in accordance with SAS No. 58. In contrast, their judgments for the footnote disclosure decision were consistent with a decision theory model of auditor behavior rather than the noncompensatory process implied by SFAS No. 5. Additional aspects of the study pertain to the additional paragraph decision of auditors. Observed judgments for these decisions are consistent with the hypothesis that additional information is conveyed beyond that provided by only a footnote disclosure. This is contrary to some recent discussions of the standards. Résumé. Les auteurs étudient les jugements relatifs aux probabilités portés par les vérificateurs dans le cadre de leurs décisions relatives à la présentation des pertes éventuelles importantes sous forme de notes infrapaginales dans les états financiers ou de paragraphes supplémentaires dans le rapport des vérificateurs. Aux États-Unis, ces jugements sont régis par le SFAS no 5 et le SAS no 58. Deux études antérieures ont donné des résultats dissemblables en ce qui a trait à la mesure dans laquelle les vérificateurs se conforment au processus de jugement et de prise de décisions que suppose le SFAS no 5. Le respect par les vérificateurs des normes du SAS no 58 n'a fait, quant à lui, l'objet d'aucune analyse. Les résultats d'une expérience menée auprès de 64 associés reponsables de la vérification dans six cabinets ont confirmé l'hypothèse selon laquelle les associés responsables de la vérification utilisent le même processus de jugement (compensatoire) lorsqu'ils décident de présenter les pertes éventuelles sous forme de notes infrapaginales que lorsqu'ils optent pour les paragraphes supplémentaires. Ce processus a amené les associés à porter des jugements pour l'ajout de paragraphes supplémentaires conformes au SAS no 58. Par opposition, leurs jugements relatifs à la présentation sous forme de notes infrapaginales étaient conformes à un modèle de comportement du vérificateur inspiré de la théorie de la décision plutôt qu'au processus non compensatoire que suppose le SFAS no 5. D'autres aspects de l'étude portent sur la décision des vérificateurs relative à l'ajout de paragraphes supplémentaires. Les jugements observés relativement à cette décision sont conformes à l'hypothèse selon laquelle d'autres renseignements sont transmis, outre ceux qui sont fournis par voie de simples notes infrapaginales. Ces résultats viennent contredire certaines analyses récentes portant sur les normes.  相似文献
