Consumer Willingness to Pay for Seafood Safety Assurances

Despite its many health benefits, seafood consumption has declined partially due to consumers' safety concerns. Efforts to provide safety assurance to consumers have focused on provision of government inspection programs; programs that both consumer groups and the seafood industry have called inadequate. This study explores consumer preferences for a wide array of alternative safety assurances. Consumers' selection of and willingness to pay for seafood safety assurances were elicited using an in-person market-like experiment. Results indicate that consumers are able to demonstrate clear preferences and values for alternative assurances. This indicates further consumer research is warranted to provide a basis for public policy recommendations regarding seafood safety assurances.     

Trends in Charitable Giving

The charitable giving of UK households has changed considerably over the past 20 years. In particular, the proportion of households giving to charity fell by 5 percentage points between 1974 and 1993–94. An increase in the average size of donations meant that total voluntary income increased in real terms over the period, but, since 1988, voluntary income has stagnated. The greatest falls in the number of givers are among households in their twenties and thirties. There are clear trends in giving across households by age and income, with younger and poorer households tending to give less. But not only are today's younger households less likely to give than today's middle-aged households; they are also less likely to give than today's middle-aged households did when they were young. These generational trends in giving do not bode well for levels of voluntary income in the future. JEL classification: D12. D16.     

Bureaucrats and Babies: Government Regulation of the Supply of Genetic Material*

One might object to the sale of genetic material on the ground that it constitutes a trade in human beings. We argue that such exchange does not constitute a morally significant departure from current practice concerning the sale of other bodily property. Some utilitarians have argued that there is no justification for suppliers of genetic material receiving the competitive market-clearing price for their product. They maintain that utilitarian objectives would be better advanced by distributing genetic material through a government board. We contend that competitive market exchange of genetic material is preferable both because it does more to further individual liberty and because it is more efficient.     

Volume and Autocovariances in Short-Horizon Individual Security Returns

This article tests for the relations between trading volume and subsequent returns patterns in individual securities' short-horizon returns that are suggested by such articles as Blume, Easley, and O'Hara (1994) and Campbell, Grossman, and Wang (1993) . Using a variant of Lehmann's (1990) contrarian trading strategy, we find strong evidence of a relation between trading activity and subsequent autocovariances in weekly returns. Specifically, high-transaction securities experience price reversals, while the returns of low-transactions securities are positively autocovarying. Overall, information on trading activity appears to be an important predictor of the returns of individual securities.     

The Nutritional Impact of the Dairy Price Support Program

This paper examines the impact of the dairy price support program and its resultant higher prices on nutritional intake, especially calcium. This assessment is particularly important because calcium is one of the two nutrients whose average intake is below the Recommended Dietary Allowance. A demand system with emphasis on dairy products is estimated, and in conjunction with data on the nutritional content of various foods, impacts on nutritional intake are measured.
