Imperfect Mileage Information and Changing Utility: A Model and Survey Results

This paper extends work which integrates misinformation into consumer utility theory. It provides a framework for measuring the cost of misinformation or the value of improved information. If automobile purchases are based on imperfect gasoline mileage information, a discrepancy results between consumers' expected and actual fuel expenditures. Based on a survey of new car buyers, the empirical analysis yields estimates of the private and social cost of inaccuracies in automobile buyers' pre-purchase gasoline mileage estimates. The reliability of mileage information varied from different sources, but many consumers found the EPA fuel-economy ratings relatively unreliable.     

Socialization,Gender, and Adolescent's Self-Reports of Their Generalized Use of Product Labels

This study examines how various aspects of the consumer socialization process affect male and female teenagers' tendencies to use product labels in general. In contrast to the traditional information-processing perspective used in many studies of gender differences and studies of labeling, this research focus more on sociological explanations for gender differences in teens' tendencies to read product labels. Specifically, because males and females are likely to receive differential consumer socialization, differences are expected in the genders' use of product labels. Male and female teenagers may be differentially taught about the importance and use of product labels through differences in exposure to marketplace-related communication from parents, peers, and mass media. Exposure to marketplace-related communication, in turn, is likely to have positive effects on teens' tendencies to use product labels in general. With the exception of exposure to mass media, results based on data from a sample of high school students generally supported this mediational model.     

Incremental Information Content of the Change in the Percent of Production Added to Inventory*

Abstract. Manufacturing firms can manipulate income by producing in excess of the quantity needed to meet current period demand, thereby allocating part of current period fixed manufacturing overhead costs from cost of goods sold to inventory. Because it is subject to manipulation, the component of earnings due to producing in excess of sales may be of lower quality than the remaining component of earnings. We investigate this possibility using a regression of security returns on unexpected income and an estimate of the change in percent of production added to inventory (CPAI). An analytical model indicates that CPAI determines the “earnings surprise” subject to manipulation by overproducing. Assuming the market recognizes this, the coefficient on CPAI should be negative because this low quality component must be deducted from the total “good news” conveyed by the change in reported earnings. Alternatively, CPAI may convey good or bad news to the market that is unrelated to the manipulation of current period earnings. Firms may increase the percent of production added to inventory in anticipation of high levels of future sales. In this case, the estimated coefficient on CPAI should be positive. Or, if the increase in the percent of production added to inventory reflects anticipation of a strike or an unexpected downturn in current sales, the estimated coefficient should be negative. Cross-sectional tests using a large sample of manufacturing firms indicate a significant positive relation between security returns and CPAI. This finding is consistent with market participants viewing CPAI as a leading indicator of firm performance. Although the results are most supportive of CPAI conveying good news, there is some evidence that CPAI is used by managers to smooth earnings and, for firms classified as smoothing earnings, there is weak evidence that the component of earnings related to CPAI is viewed by market participants to be of lower quality.     

PAY EQUITY AND COMPARABLE WORTH

An important and emerging public policy consideration… generally called equal pay for comparable worth…has received great attention from those who influence or report public policy initiatives. The comparable worth movement is directed at pay equity issues, primarily between men and women. The source of controversy surrounding comparable worth concerns the mechanism for determining wages in the economy…either an unrestricted market process or a subjective valuation process by designated "pay equity experts." Although the pay and allocation mechanisms and their side effects are controversial, other important questions concern the actual method of equity determination to be used in implementing comparable worth. This paper analyzes, from a general public policy perspective, many of the issues and much of the evidence surrounding comparable worth initiatives.
