Temporary Layoffs and Unemployment Insurance: Is Experience Rating Desirable?

Abstract. This paper explores how the introduction of an experience-rated system of unemployment insurance affects employment and welfare in a model where implicit contracts between firms and workers give rise to wage rigidities and unemployment. In the literature, it has been argued that experience-rated systems of unemployment insurance may reduce long-term employment as firms anticipate the higher costs of layoffs implied by experience rating. Our analysis shows that the introduction of experience rating may increase or decrease long-term employment but it unambiguously raises welfare.     

The Campus Parking Game: A Demonstration of Price Discrimination and Efficiency

This article presents a classroom game that allows students to directly experience the welfare improvements that can result from price discrimination. The demonstration uses a very familiar decision-making scenario, campus parking, to introduce the concept of price discrimination as well as reinforce the concepts of opportunity cost, consumer surplus, and search costs. This game can be used in a variety of classes, including principles, intermediate theory, industrial organization, or environmental economics, and can be conducted in a 50-minute class period with follow-up discussion in the next class.     

Shareholders and Corporate Community Involvement in Britain

Corporate community involvement is attracting increasing interest in Britain, but what do shareholders feel about this use of company assets? This timely survey of top UK corporate donors provides interesting data on current practice and explores the degree to which shareholders are consulted.

Competition Policy Convergence: Where Next?

As the 20th Century dawned, there were radical divergences in the policies individual nations pursued toward restraints of competition by cartels and monopolies. Since World War II there has been considerable convergence; many nations have adopted explicit pro-competition policies. This paper traces the reasons for the divergence and then convergence and asks what important steps remain to be taken, especially where the concerns of international trade policy and competition policy intersect. A proposed augmentation of the World Trade Organization's functions to deal with competition policy issues is examined.     

Nonf arm Labor Market Participation of Farm Women

Structural changes in Saskatchewan agriculture have led to significant changes in the time allocation of labor of farm women. This paper analyzes the nonfarm labor market participation and labor supply of farm women in the theoretical context of a household production function and contrasts them with those of men. Participation is analyzed using probit models, and nonfarm labor supply functions are estimated using tobit models. Personal characteristics such as age, education, number of children and nonfarm labor participation of the spouse are significantly related to the nonfarm labor market participation and labor supply of farm women, and the direction of influence is as expected. Farm characteristics such as farm size and type are significant in the case of males but not for females. Labor market characteristics are represented only by distance to the nearest center of Complete Shopping Center status or higher and, while this variable is negatively significant for males as expected, it is not significant for females Les changements structurels qui on frappé l'agriculture de la Saskatchewan ont entraîné des modifications significatives à la répartition du temps des agricultrices en matière de travail. L'article présente une analyse de la participation au marché du travail non agricole, ainsi que de l'offre de main-d'oeuvre des agricultrices, dans le contexte théorique d'une fonction de production de ménage, en comparaison avec la situation observée chez les hommes. Le degré de participation e'tait analysé à partir de modèles probit et les fonctions d'offre de main-d'oeuvre non agricole étaient estimées à partir de modéles tobit. Les caractères personnels comme l'âge, I'instruction, le nombre d'enfants et la participation du conjoint à un travail non agricole étaient significativement reliés, dans le sens attendu, à la participation des femmes au marché du travail non agricole et au temps qu'elles pouvaient y consacrer. Les caractères de l'exploitation, superficie et type, n'étaient significatifs que pour les hommes mais pas pour les femmes. Le seul caractére du marché de main-d'oeuvre considéré était la distance entre la ferme et l'agglomération la plus proche de niveau de centre commercial complet ou de niveau supérieur. Bien que, comme on pouvait s'y attendre, cette variable était significativement négative dans le cas des hommes, elle n'avait pas de valeur significative pour les femmes     

A note on the returns from minimum variance investing

Disappointed with the performance of market weighted benchmark portfolios yet skeptical about the merits of active portfolio management, investors in recent years turned to alternative index definitions. Minimum variance investing is one of these popular concepts. I show in this paper that the portfolio construction process behind minimum variance investing implicitly picks up risk-based pricing anomalies. In other words the minimum variance tends to hold low beta and low residual risk stocks. Long/short portfolios based on these characteristics have been associated in the empirical literature with risk adjusted outperformance. This paper shows that 83% of the variation of the minimum variance portfolio excess returns (relative to a capitalization weighted alternative) can be attributed to the FAMA/FRENCH factors as well as to the returns on two characteristic anomaly portfolios. All regression coefficients (factor exposures) are highly significant, stable over the estimation period and correspond remarkably well with our economic intuition. The paper also shows that a direct combination of market weighted benchmark portfolio and risk based characteristic portfolios will provide a statistically significant improvement over the indirect pickup via the minimum variance portfolio.     

Duell oder Berichterstattung?

Televised debates between the German Chancellor and his challenger were held for the first time in the election campaign in 2002. Hence we had the opportunity to examine the effects of debates as well as the impact of the follow-up news coverage of the debate. By combining a content analysis of debate coverage and a representative survey, we explored how voters’ reception of the first TV debate and their reception of the debate coverage interacted. Voters were influenced both by the impression they formed by directly viewing the debate and by the indirect impression they gained from follow-up media coverage. On the one hand we found an impact on voters’ views of the candidates’ appearance and of who won the debate. On the other hand we found an impact on voters’ general notions of the candidates’ personalities and competences. Furthermore there were — probably rather short-lived — shifts of candidate and party preferences.     

Challenges of AACSB international accreditation for business schools in the United States and Europe

The Association to Advance Collegiate Schools of Business International (AACSB International) is committed to its role in setting worldwide standards to enhance the quality of management education. The organization is expanding its brand presence in Europe, where business schools are beginning to seek AACSB International accreditation. In the United States, an increase in the number of business schools seeking AACSB International accreditation is also occurring. Business school leaders not only see the transcendent importance of AACSB International accreditation; they also realize the challenges that are involved in the accreditation process. The focus of our discussion is on the challenges confronted by business schools in both the United States and Europe. We compare and contrast the challenges on both continents. © 2005 Wiley Periodicals, Inc.
