Time as a Direct Source of Utility: The Case of Price Information Search for Groceries

A “joint production” model that combines aspects of household production and the economics of information is formulated to explain variation in time spent in price information search for groceries by dual earner households. Enjoyment of search time, a psychological variable, is incorporated into the model. Empirical estimation using grocery expenditure data indicates that enjoyment, income, age, the price of search time, presence of young and teenage children, daily use of a microwave oven, and the percentage of a market basket filled with name brand items are significant factors in explaining variation in time spent in price information search.     

Consumer microwave use of melt-blown material for fat reduction

Consumers, who use their microwave oven to heat bacon, were asked to heat either bacon or sausage on non-woven, melt-blown material and on paper towels in the microwave oven. The consumers were surveyed about their concerns for fat and cholesterol in the diet. The panelists also were asked to evaluate the appearance, greasiness, ease of use and overall acceptability. A survey of the consumers indicated that they were concerned about fat and cholesterol in the diet and purchased items lower in fat. However, 28% of these individuals save and re-use bacon fat. Panelists liked the appearance of bacon heated in the melt-blown pad better than on the paper towels and found it easier to use. Sausage heated in the melt-blown pad was found to be less greasy and more acceptable than that heated on paper towels.     

A METHOD FOR EVALUATING SUPPLY RESPONSE TO PRICE UNDERWRITING

In this paper a method for evaluating the supply response of individual producers to a price underwriting scheme is presented. The method includes precise formulae to take account of the impact of price underwriting on the producer's uncertain conditions. The Australian Wheat Board's guaranteed minimum price scheme is taken as a specific example of price underwriting in practice. Results show the scheme to lead to only relatively small supply responses. The impact on producer behaviour of an increase in price uncertainty in the presence of an underwriting scheme is also demonstrated in the paper.     

Productivity of New York Dairy Farms Measured by Nonparametric Malmquist Indices

The productivity of 70 individual New York dairy farms, decomposed into technical efficiency change and technological change components, was measured annually from 1985 to 1993 from output distance functions estimated using nonparametric programming methods. Technology is measured regressively only if it is regressive to all previous periods rather than just the immediate previous period. Productivity increase averaged 2.6 per cent annually, mostly from gains in technological improvements, since average efficiency decreased slightly. Twenty-five per cent of the farms failed to increase productivity sufficiently over the period to offset the decreased ratio of output to input prices.     

Economics and the treatment of AIDS: a preliminary assessment

This paper applied cost-effectiveness analysis to the use of drug therapy in the treatment of AIDS. The empirical approach adopted overcame the facts that the samples of patients had varying clinical prognoses, had variable entry dates into the samples and, because AIDS is a terminal disease, had variable exit dates. Holding these variables constant, administration of the drug AZT proved to be a less costly alternative than other existing palliatives for AIDS. The sub-sample of patients treated with AZT had lower hospitalization costs, lower caring costs and sufferers had an increased ability to continue to participate for longer as economically active members of society.
