The Use of Unsigned Earnings Quality Measures in Tests of Earnings Management

This paper examines the implications of using the absolute value of discretionary accruals when testing for earnings management. First, we analytically develop the mean and variance of the distribution of absolute discretionary accruals, and show that the expected value is an increasing function of the variance in the underlying error term from the first‐stage discretionary accrual estimation model. Second, we highlight several firm characteristics that are related to the error variance in discretionary accrual estimation models. Using simulations, we show that correlation between the earnings management partitioning variable and these firm characteristics leads to an overrejection of the null hypothesis of no earnings management. Third, we provide research design suggestions to help researchers mitigate the potential bias arising from the use of unsigned measures of earnings management. Using these suggestions, we replicate a recent study, and demonstrate that the inferences change after controlling for operating volatility.     

Effects of Consumption Frequency on Believability and Attitudes Toward Alcohol Warning Labels

Alcohol consumption frequency and alcohol warning label type are examined for their influence on label believability, attitude toward the label, and attitude confidence. Findings from a convenience sample of students indicate a differential impact among five warning labels on label believability and label attitudes. As expected, frequent alcohol users find the labels to be significantly less believable and less favorable than occasional/nonusers of alcohol. However, occasional/nonusers of alcohol hold more confident attitudes toward the labels than frequent alcohol users.     

The Use of Vivid Stimuli to Enhance Comprehension of the Content of Product Warning Messages

Thousands of consumers are injured annually using consumer products. It is intuitively plausible that vivid product warnings may improve communication of the hazards associated with product use, yet vividness effects have been difficult to demonstrate empirically. Vivid product warnings are shown to increase accurate memory of the hazards associated with product use by enhancing cognitive elaboration on the content of a product warning message. Moreover, vivid product warnings may not, in and of themselves, generate negative elaborations regarding the safety of the product in question.     

SIZE MATTERS: THE ECONOMIC VALUE OF BEACH EROSION AND NOURISHMENT IN SOUTHERN CALIFORNIA

Despite the widespread use of nourishment in California, few studies estimate the welfare benefits of increased beach width. This paper relies on panel data funded by National Oceanic and Atmospheric Administration and other agencies. Beach choices of respondents were combined with beach attribute data to reveal how changes in width affect choice and the economic value of beach visits. We use a random‐utility approach to show that the value of beach width varies for different types of beach uses: water contact, sand‐, and pavement‐based activities. We also find that the marginal value of beach width depends on initial beach width. (JEL Q50)     

Cross-Cultural Generalizability of a Scale for Profiling Consumers' Decision-Making Styles

Most studies that have developed and validated models and instruments in consumer affairs research have used U.S. samples. As a result, their cross-cultural generalizability remains unknown. This study reports a cross-cultural examination of a scale for profiling consumers' decision-making styles using a New Zealand sample. Examination of the scale's psychometric properties (i.e., dimensionality and reliability) offers general support for the scale's applicability to a different culture. Some differences were detected, however. The paper concludes with a discussion of these differences and the implications of the findings.     

Age,Product Nutrition,and Label Format Effects on Consumer Perceptions and Product Evaluations

Nutrition label format effects across different levels of product nutrition value and groups of younger (under 58 years; average 46 years) and older consumers (58 years or more; average 70 years) are examined using a 3 × 2 × 2 experimental design. Age interacts with nutrition level in affecting nutrition evaluation measures with older consumers displaying smaller differences in nutrition attitude and purchase likelihood for a low versus a high nutrition value product. Older consumers also perceive all labels as more difficult to understand. Consumer performance on judgment tasks vary across label formats and nutrition value manipulations. Implications for consumer welfare and future research are offered.     

Using Generalized Method of Moments to Test Mean-Variance Efficiency

This paper develops tests of unconditional mean-variance efflciency under weak distributional assumptions using a Generalized Method of Moments framework. These tests are potentially more robust than commonly employed tests which rely on the assumption that asset returns are normally distributed and temporarily i.i.d. Using returns for size-based portfolios from 1926 to 1988 we show that the conclusion concerning the mean-variance effilciency of market indexes can be sensitive to the test considered.
