Gender and competition

In almost all European Union countries, the gender wage gap is increasing across the wage distribution. In this 2008 presidential lecture I briefly survey some recent studies aiming to explain why apparently identical women and men receive such different returns and focus especially on those incorporating psychological factors as an explanation of the gender gap. Research areas with high potential returns to further analysis are identified. Several examples from my own recent experimental work with Patrick Nolen are also presented. These try to distinguish between the role of nature and nurture in affecting behavioural differences between men and women that might lead to gender wage gaps.     

Does santa have a great job? Gift shopping value and satisfaction

For good or bad, shopping and gifting are intertwined. This research looks at sources of gratification associated with shopping for gifts. More particularly, the roles played by general and specific shopping orientations in shaping gift shopping value and satisfaction are examined. Results from testing a theoretical model suggest that gift shopping orientations, such as agape, may dominate general shopping orientations, such as price consciousness. Also, the important role played by utilitarian shopping value is consistent with gift shopping more as a job than as a source of leisure. However, the results fall short of suggesting a negative relationship between gift shopping and hedonic shopping value. So gift shopping may be a job, but a job that is not so horrible after all. © 2007 Wiley Periodicals, Inc.     

FUTURE DIRECTIONS IN UNDERGRADUATE INSURANCE EDUCATION: ACADEMIC AND REAL WORLD PERSPECTIVES

Abstract: The authors discuss the hiring patterns of some insurers and examine why insurers do not always seek out students with risk management and insurance backgrounds. The authors suggest that it is important for universities and insurers to work more closely so that students coming out of college insurance programs are well prepared to work in the insurance industry.     

A Monte Carlo investigation of the accuracy of multivariate CAPM tests

In a multivariate regression model relating individual returns to the market return, CAPM implies non-linear restrictions on the parameters. Several asymptotically valid tests of these restrictions have been suggested. The existing Monte Carlo evidence shows that some of these tests are unreliable for reasonable sample sizes, but does not indicate well which tests are reliable. This paper reports the results of an extensive Monte Carlo experiment. Shanken's CSR test and Jobson and Korkie's corrected likelihood ratio test are quite accurate in all cases we consider.     

Evolution of global airline strategic alliance and consolidation in the twenty-first century

Global airline strategic alliances have emerged since the late 1980s, and their number has slowly risen through the years. Will the number of such alliances continue to proliferate? Or will airlines consolidate with one another to form mega-carriers? In this paper, the likelihood of various airline consolidation and alliance development possibilities was examined based on a number of high-level trends and forces. The most probable near-term industry alliance and consolidation structure is described, accompanied with a probable path of evolution. These predictions have important implications for managers of strategic alliances, carriers who are currently in an alliance as well as carriers who are planning to join one.     

THE RISK STRUCTURE OF INTEREST RATES AND INTERDEPENDENT BORROWING COSTS: THE IMPACT OF MAJOR DEFAULTS

This paper develops a new methodology for evaluating the impact of economic events on bond yields. Term structure information and implicit forward rates are used to generate expected bond yields, and the difference between actual and expected yields is interpreted as the information effect of the event. The methodology is applied to two studies of municipal default: the New York City default and the more recent Washington Public Power Supply System (WPPSS) default. The analysis provides evidence that the New York City default did have a significant impact on the interest cost of municipal financing in general. In the case of WPPSS, however, there is no indication of a significant default impact.     

Capital management in mutual financial institutions

Capital management by mutual financial institutions (such as credit unions) provides a valuable testing ground for assessing the impact of capital regulation and theories of managerial behaviour in financial institutions. Limited access to external equity capital means that capital accumulation must be met primarily by reliance on retained earnings. To deal with shocks to the capital position and avoid breaching regulatory requirements, managers will aim to have a buffer of capital in excess of the regulatory minimum. Moreover, mutual governance arrangements and an absence of capital market discipline mean that managers have discretion to set target capital ratios which differ significantly from industry averages. This paper develops a formal model of capital management and risk management in mutual financial institutions such as credit unions which reflects these industry characteristics. The model is tested using data from larger credit unions in Australia, which have been subject to the Basel Accord Risk Weighted Capital Requirements since 1993. The data supports the hypothesis that credit unions manage their capital position by setting a short term target profit rate (return on assets) which is positively related to asset growth and which is aimed at gradually removing discrepancies between the actual and desired capital ratio. Desired capital ratios vary significantly across credit unions. There is little evidence of short run adjustments to the risk of the asset portfolio to achieve a desired capital position.
