Selecting Pesticides and Nonchemical Alternatives: Green Thumbs' Rules of Thumb Decision Tools

This study of a sample of home gardeners indicates that rules of thumb, or heuristics, are used to select between chemical pesticides and nonchemical alternatives. Such rules of thumb serve to simplify otherwise complicated choice decisions. Heuristics commonly used to choose pesticides include how safe, effective, efficacious, and economical they are, whereas for alternative products consumers more often take into account convenience, efficiency, competency, and handiness. Generally, in an overall ranking of 24 individual choice attributes, pesticies rank low on these attributes where alternatives rank high and vice versa. Gender, age, and years using pesticides are significantly correlated with pesticide selection.     

In-Kind Food Assistance and Consumer Food Choice

In-kind food assistance was the mainstay of federal food programs until the food stamp program expanded. Analysis of aggregate data suggests that large donations of cheese and butter since 1982, through the Temporary Emergency Food Assistance Program, replaced recipients’ normal purchases of the donated products, reduced consumption of close substitutes, and increased consumption of certain other protein foods. Programs of this type appear to have limited ability to enhance total demand for products in surplus.     

A Test of Consumer Awareness for Adults

The purpose of this study was to develop an instrument to measure adult awareness of consumer product/service information sources, consumer protection laws and channels of recourse. The process included identification of prevalent consumer problems, development of test items based on the identified problems, and assessments of the content validity and the reliability of the instrument. The process of construct validity was initiated by developing and testing hypotheses concerning the relationships between scores on the instrument and selected socio-economic characteristics of consumers. Low consumer awareness scores were predominant, supporting the need for consumer education for adults.     

An Economic Analysis of Interest Rate Swaps

Interest rate swaps, a financial innovation in recent years, are based upon the principle of comparative advantage. An interest rate swap is a useful tool for active liability management and for hedging against interest rate risk. The purpose of this paper is to provide a simple economic analysis of interest rate swaps. Alternative uses of and the appropriate valuation procedure for interest rate swaps are described.     

Arbitrage Chains

A privately informed trader will engage in costly arbitrage, that is, trade on his knowledge that the price of an asset is different from the fundamental value if: (1) his order does not move the price immediately to reflect the information; and (2) he can hold the asset until the date when the information is reflected in the price. We study a general equilibrium model in which all agents optimize. In each period, there may be a trader with a limited horizon who has private information about a distant event. Whether he acts on his information, and whether subsequent informed traders act, is shown to depend on the possibility of a sequence or chain of future informed traders spanning the event date. An arbitrageur who receives good news will buy only if it is likely that, at the end of his trading horizon, a subsequent arbitrageur's buying will have pushed up the expected price. We show that limited trading horizons result in inefficient prices, because informed traders do not act on their information until the event date is sufficiently close. We also show that limited horizons can arise because of the cost-carry associated with holding an arbitrage portfolio over an extended period of time.     

Testing the Monopoly Union Model: A Stochastic Frontier Approach

This study applies stochastic frontier analysis to test the monopoly union model. This approach allows the use of a wider data set than has been previously employed. We fit a stochastic cost frontier to data from the U.S. manufacturing sector that includes exogenous sources of potential inefficiency including unionization. Our findings suggest that over the 1972–1982 time period, more heavily unionized industries in the U.S. manufacturing sector were more likely to operate off their labor demand curve. This result is inconsistent with the monopoly union model predictions.
