The terms of authority

Many exchanges involve only a partial transfer of ownership rights. The employment relation is the standard example — an employer purchases the authority to use the worker's time in the most profitable way, within specified limits. This paper develops a model of the forces which determine the terms of authority.     

On interpreting security returns during the ex-dividend period

In this paper we examine the ex-dividend day returns of several taxable and non-taxable distributions. The ex-dividend day returns for the taxable common stocks are consistent with the hypothesis that dividends are taxed more heavily than capital gains. However, the ex-dividend day returns of preferred stocks suggest that preferred dividends are taxed at a lower rate than capital gains; non-taxable stock dividends and splits are priced on ex-dividend days as if they are fully taxable; and non-taxable cash distributions are priced as if investors receive a tax rebate with them. We also find that each of these distributions exhibits abnormal return behavior for several days surrounding the ex-dividend day. We investigate several possible explanations for this anomaly, but none is capable of explaining the phenomenon.     

A Market-based Risk Classification of Financial Institutions

In this article we derive, estimate, and analyze a multifactor model of the monthly holding period returns on the stocks of exchange-traded financial institutions. In addition to bond and equity returns, the factors include default, liquidity, and term structure risk premiums plus variables that measure changes in deposit demand. To ensure that our sample has a large number of firms, we use data from January 1981 through December 1988. The equity return explains a large share of time-series variation in financial institutions' returns. The additional factors implied by theory have little incremental explanatory power. The two-factor model regression coefficients have considerable cross-sectional variation. This permits us to group intermediaries into portfolios with similar risk exposures. These portfolios bear no relation to the SIC codes that group intermediaries by their charters and lines of business.     

Spontaneous selection: The influence of product and retailing factors on consumer impulse purchases

Our research examines the effect of product characteristics and retailing factors on the likelihood a consumer makes an impulse purchase. We present a framework for understanding the impulse buying process and use it to explain our findings. Our nested logit model uses data from an adult panel of grocery shoppers over three major household grocery shopping trips. The results indicate that product characteristics have a fifty percent greater influence on impulse buying than do retailing factors. Of the three product characteristics investigated, the hedonic nature of the product has the greatest influence on impulse buying. Of the three retail factors, a store environment with a high–low pricing strategy influences impulse buying the most. Our findings suggest that retailers who want to encourage impulse buying behavior utilize promotional activities and merchandising tactics that attract consumers' attention to emotionally appealing products.
