A leximin characterization of strategy-proof and non-resolute social choice procedures

Summary. We characterize strategy-proof social choice procedures when choice sets need not be singletons. Sets are compared by leximin. For a strategy-proof rule g, there is a positive integer k such that either (i) the choice sets g(r) for all profiles r have the same cardinality k and there is an individual i such that g(r) is the set of alternatives that are the k highest ranking in i's preference ordering, or (ii) all sets of cardinality 1 to k are chosen and there is a coalition L of cardinality k such that g(r) is the union of the tops for the individuals in L. There do not exist any strategy-proof rules such that the choice sets are all of cardinality to k where . Received: November 8, 1999; revised version: September 18, 2001     

The effect of globalization and legal environment on voluntary disclosure

We examine how interactions with foreign capital, product, and labor markets affect the disclosure practices of non-U.S. multinational firms. Drawing on literature related to multinationals, country-level legal institutions, and accounting disclosures, we expect that the relation between globalization and voluntary disclosure will be conditioned by the legal environment in a firm's home country. Specifically, while firms from countries with a strong legal environment (e.g., common-law countries) already face pressure for good disclosure, globalization can increase the benefits associated with good disclosure to firms from weak legal environments (e.g., civil-law countries). We use a self-constructed voluntary disclosure index and hand-collected disclosure and foreign activity data for 643 non-U.S. firms from 30 countries for 2003. We find a significant interaction between globalization and the legal environment. This indicates that for the same level of globalization, there is more voluntary disclosure for firms based in weak legal environments. Our results suggest that globalization is an important variable that has been overlooked in much of the previous cross-country research.     

A Bayesian mixed logit–probit model for multinomial choice

In this paper, we introduce a new flexible mixed model for multinomial discrete choice where the key individual- and alternative-specific parameters of interest are allowed to follow an assumption-free nonparametric density specification, while other alternative-specific coefficients are assumed to be drawn from a multivariate Normal distribution, which eliminates the independence of irrelevant alternatives assumption at the individual level. A hierarchical specification of our model allows us to break down a complex data structure into a set of submodels with the desired features that are naturally assembled in the original system. We estimate the model, using a Bayesian Markov Chain Monte Carlo technique with a multivariate Dirichlet Process (DP) prior on the coefficients with nonparametrically estimated density. We employ a “latent class” sampling algorithm, which is applicable to a general class of models, including non-conjugate DP base priors. The model is applied to supermarket choices of a panel of Houston households whose shopping behavior was observed over a 24-month period in years 2004–2005. We estimate the nonparametric density of two key variables of interest: the price of a basket of goods based on scanner data, and driving distance to the supermarket based on their respective locations. Our semi-parametric approach allows us to identify a complex multi-modal preference distribution, which distinguishes between inframarginal consumers and consumers who strongly value either lower prices or shopping convenience.     

Response Format Effects in Encounter Norm Questions

Survey response format has been shown to influence norm prevalence (percentage reporting a norm) and the numerical value of the reported norm. This article summarizes an experiment where respondents were randomly assigned to one of two conditions. In the semi-open response format treatment, respondents (n = 817) “wrote in a number” for an acceptable number of visitor encounters. In the closed format treatment, individuals (n = 826) “circled a number” of acceptable encounters along a range of possible responses. Hypothesis 1 predicted that norm prevalence would be higher for the closed format than the semi-open. Hypothesis 2 predicted that the mean tolerance level would differ in the two treatments. Results supported hypothesis 1. The percent reporting a norm was statistically higher in the closed versus the semi-open treatment. Results failed to support hypothesis 2. The average tolerance levels for the closed and semi-open formats were statistically equivalent.     

Industry specialist auditors, outsider directors, and financial analysts

This study investigates the relationships among industry specialist auditors, outside directors, and financial analysts. Specifically, we examine the effect of analyst coverage on the association between auditor industry specialization and outside directorship. We find that outside directors are less likely to hire industry specialist auditors for firms with high analyst coverage than for firms with low analyst coverage. Our findings suggest that analyst coverage moderates outside directors’ demand for industry specialist auditors, that is, financial analysts may compete with industry specialist auditors to some extent in monitoring financial reporting process.     

Modeling the currency issue

This paper, which includes a critique of an article that appeared in the [New Zealand]Reserve Bank Bulletin, considers the difficulties of building a forecasting model of the optimum structure of the currency (that is, notes and coins) in circulation. The reviewed model leads to predictions that are not consistent with recent experience and there are theoretical objections to the specification of both the independent and the dependent varibles. Alternative approaches are explored, but the conclusion is that this aspect of money is probably not amenable to mathematical modeling.     

The impact of the CSRC Regulation No. 12-1996 on the credibility of Chinese IPO earnings forecasts

This study examines whether the Chinese Securities Regulatory Commission (the CSRC) Regulation No. 12-1996, Announcement of Some Rules on the Issuance of Shares, may enhance the credibility of management earnings forecasts in Chinese IPO prospectuses. Using a sample of 858 IPO earnings forecasts over the period 1991–2005, we find that earnings forecasts have been less optimistic and more accurate after the regulation was promulgated on December 26, 1996. Overall, our findings suggest that the CSRC Regulation No. 12-1996 can improve the reliability of Chinese IPO earnings forecasts.     

Korean American Males’ Serious Leisure Experiences and Their Perceptions of Different Play Styles

This study examined Koreans Americans’ serious leisure experience with different racial groups. Interviews were conducted with 15 Korean male basketball and soccer players. A key finding was that participants recognized different styles of play between Korean Americans and other racial groups. While some participants cared little about other players’ race/ethnicity, other participants played exclusively with Korean Americans and preserved or promoted their ethnic identity. While Stebbins (1982) argues that serious leisure provides eight durable benefits, our findings suggest self-identification may be another durable benefit, at least among ethnic and/or racial minorities.
