Safety of the U.S. food supply: consumer concerns and behaviour

To examine consumer concern about food safety, identify characteristics of those most concerned, and determine behavioural responses to concerns, we used mailed questionnaires to survey a random sample of 630 adults. Eighty-eight percent of respondents were very or somewhat concerned about safety of the food supply. Subjects perceived greatest likelihood of harm from chemicals and lowest likelihood of harm from bacterial contamination. Relative to other concerns about food such as cost or taste, food safety ranked low. Because the concern was across all ages, education levels, genders, and places of residence, we were unable to define a type of person most likely to be concerned about food safety. Less than half the subjects had changed dietary behaviour in response to food safety concerns. Foods reduced or eliminated from the diet most often were meats, fruits, eggs and vegetables. The findings indicate that consumers need risk assessment education and help in making food choices that do not compromise diet quality.     

Trading volume reactions to a change in dividend policy: the Canadian evidence*

Abstract. This study examines the volume of trading in the stock of 34 Canadian companies that initiated a policy of regular cash dividends during the period 1972–1982. Using a time-series methodology linked to changes in Canadian tax legislation, we test whether the volume of trading surrounding first-time dividend adoptions declined after 1978, a year when tax legislation changed the taxation of dividends toward tax neutrality for investors in high tax brackets. We observe a significant trading volume decline after 1978, which we interpret as implying that fewer investors wanted to dispose of initial dividend stocks after 1978. The result is inconsistent with dividend irrelevance theories and possibly points to tax clientele relevance in Canada. Résumé. Les auteurs examinent le volume de titres négociés pour 34 sociétés canadiennes ayant mis en place une politique de versement périodique de dividendes en espèces durant la période 1972–1982. À l'aide d'une méthodologie de séries chronologiques liée aux changements apportés à la législation fiscale canadienne, les auteurs vérifient si le volume des titres négociés dans le contexte de l'adoption initiale de cette politique de dividendes a décliné après 1978, année au cours de laquelle le fisc a modifié l'imposition des dividendes pour pencher vers la neutralité fiscale pour les investisseurs appartenant aux tranches d'impôt élevées. Ils observent un déclin appréciable du volume de titres négociés après 1978, déclin qui suppose, selon eux, qu'un moins grand nombre d'investisseurs ont voulu se défaire de telles actions après 1978. Ce résultat s'oppose aux théories de la non-pertinence du dividende et pourrait indiquer la pertinence de la «clientèle fiscale» au Canada.     

Information,Ownership Structure,and Shareholder Voting: Evidence from Shareholder-Sponsored Corporate Governance Proposals

This paper examines how information and ownership structure affect voting outcomes on shareholder-sponsored proposals to change corporate governance structure. We find that the outcomes of votes vary systematically with the governance and performance records of target firms, the identity of proposal sponsors, and the type of proposal. We also find that outcomes vary significantly as a function of ownership by insiders, institutions, outside blockholders, ESOPs, and outside directors who are blockholders. These results suggest that both public information and ownership structure have a significant influence on voting outcomes.     

Can Capital Income Taxes Survive in Open Economies?

Optimal-tax theory forecasts that small open economies should not tax capital income. Yet, countries do tax capital income. Why the inconsistency? This paper shows that use of the double-taxation convention, whereby governments credit taxes paid abroad against domestic taxes, helps explain this inconsistency. In particular, capital income will be taxed if a dominant capital exporter acts as a Stackelberg leader when setting its tax policy. Due to the convention, other countries will then tax capital imports, making it attractive for the dominant capital exporter to tax capital income. Without a dominant capital exporter, however, the model still forecasts no capital-income taxes.     

Bank Capital Regulation of Trading Portfolios: An Assessment of the Basel Framework

In setting minimum capital requirements for trading portfolios, the Basel Committee on Banking Supervision (1996, 2011a, 2013) initially used Value‐at‐Risk (VaR), then both VaR and stressed VaR (SVaR), and most recently, stressed Conditional VaR (SCVaR). Accordingly, we examine the use of SCVaR to measure risk and set these requirements. Assuming elliptically distributed asset returns, we show that portfolios on the mean‐SCVaR frontier generally lie away from the mean‐variance (M‐V) frontier. In a plausible numerical example, we find that such portfolios tend to have considerably higher ratios of risk (measured by, e.g., standard deviation) to minimum capital requirement than those of portfolios on the M‐V frontier. Also, we find that requirements based on SCVaR are smaller than those based on both VaR and SVaR but exceed those based on just VaR. Finally, we find that requirements based on SCVaR are less procyclical than those based on either VaR or both VaR and SVaR. Overall, our paper suggests that the use of SCVaR to measure risk and set requirements is not a panacea.
