This study examines the influence of day-of-the-week patterns in security returns on long-run IPO underperformance. Comparisons are made between the IPOs in Ritter's [20] database, and a constructed set of matching firms based on SIC code and size, using NYSE, AMEX, and NASDAQ securities. It is found that virtually all of the IPO underperformance occurs on Mondays and Tuesdays and that the degree of underperformance significantly differs from other days. Thus, a common explanation may exist for the general day-of-the-week pattern in security returns and IPO long-run underperformance. 相似文献

Summary Economic design of one-sided screening procedures for improving outgoing product quality based on a screening variable is
considered for the case with all parameters unknown. It is assumed that the performance and screening variables are jointly
normally distributed and that costs are incurred by screening inspection, acceptance of an imperfect item, and disposition
of a rejected one. A method for finding optimal cutoff value based on the predictive distribution is presented. 相似文献

Our paper provides a brief review and summary of issues and advances in the use of latent structure and other finite mixture models in the analysis of choice data. Focus is directed to three primary areas: (1) estimation and computational issues, (2) specification and interpretation issues, and (3) future research issues. We comment on what latent structure models have promised, what has been, to date, delivered, and what we should look forward to in the future. 相似文献

Business ethics has gained much attention over the past decade in both work and educational settings. This study used a version of Lysonski and Gaidis' (1991) ethical vignettes to examine by gender the ethical views of 165 Canadian undergraduate management students, to examine the psychometric properties and construct validity of the instrument, and to determine if the instrument is a useful tool for introducing undergraduates to the topic of ethics in management practice. Results showed that while the instrument is a useful teaching tool, it has psychometric and validity inadequacies that need to be corrected.Robert Loo is currently a Professor of Human Resource Management and Organizational Studies in the Faculty of Management at the University of Lethbridge, Canada. Over the past 20 years, he has published extensively in the management and psychology literature. Ethics is a key theme throughout every management course he teaches. Bob strives to make ethics a relevant and interesting issue for students by using a variety of learning techniques such as cases, videos, self-assessment tools, and research projects. 相似文献

Empirical studies provide compelling evidence that economic agents do not adopt the complete range of energy-efficient technologies that are cost-effective under prevailing prices and market conditions. Analysts commonly attribute this anomaly to the use of high discount rates in energy-related decisions-an interpretation that is difficult to reconcile with standard models of rational choice. This paper recasts the controversy from the perspective of economic theory and finds that market failures related to asymmetric information, bounded rationality, and transaction costs are major contributors to the so-called "efficiency gap." 相似文献

This paper presents the basic analytics of a debt/equity swap and illustrates the concept with a detailed example of American Express Bank's swap transactions that began in 1986 and have resulted in construction of seven hotels in Mexico during the course of the swap agreement. The economics of the swap are presented from the lending bank's view, from the foreign direct investor's view, and from the borrowing country's view. It is concluded that: swaps offer net benefits to the borrower country when additional investment is generated (from the swap transaction itself and/or from encouraging further investment as a result of the swap policy); they offer net benefits to the lender when future loan servicing prospects are poor and viable investment opportunities exist; and they offer net benefits to the direct investor when the cost of financing the investment through the swap is less than for alternative financing sources.
The analytical framework presented here allows the bank lender to formally compare alternatives of holding impaired LDC loans on its books, selling the loans in the secondary market, trading the loans for loans from another country, and swapping the loans for equity investments in the borrowing country. It similarly allows the government policymaker to compare the relevant economic costs and benefits of swaps, so that better swap policies can be developed. 相似文献

Technological and financial approaches to risk management in agriculture: an integrated approach* 总被引:1,自引:0,他引:1
Robert G. Chambers John Quiggin 《The Australian journal of agricultural and resource economics》2004,48(2):199-223
In the present paper, risk‐management problems where farmers manage risk both through production decisions and through the use of market‐based and informal risk‐management mechanisms are considered. It is shown that many of these problems share a common structure, and that a unified and informative treatment of a broad spectrum of risk‐management tools is possible within a cost‐minimisation framework, under minimal conditions on their objective functions. Fundamental results are derived that apply regardless of the producer's preference towards risks, using only the no‐arbitrage condition that agricultural producers never forego any opportunity to lower costs without lowering returns. 相似文献

Summary. Combining a strategy model, an inference procedure and a new experimental design, we map sequences of observed actions in repeated games to unobserved strategies that reflect decision-makers’ plans. We demonstrate the method by studying two institutional settings with distinct theoretical predictions. We find that almost all strategies inferred are best responses to one of the inferred strategies of other players, and in one of the settings almost all of the inferred strategies, which include triggers to punish non-cooperators, are consistent with equilibrium strategies. By developing a method to infer unobserved repeated-game strategies from actions, we take a step toward making game theory a more applied tool, bridging a gap between theory and observed behavior.Received: 23 December 2002, Revised: 19 April 2005, JEL Classification Numbers:
