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. 相似文献

The frequency of retail price adjustment differs across goods, both in low inflationary environments, such has the United States, and in high inflationary environments typical of less developed countries. We develop a multishock menu cost model in which retailers intermediate trade between producers and consumers. Since the cost share of intermediate inputs varies across goods, the model produces a cross-sectional distribution of frequency of price adjustment even though firms face a common menu cost. The model is evaluated using a rich micropanel of retail prices in Ecuador in a period spanning a financial crisis and subsequent dollarization. 相似文献

This study examines the effect of unionization on manufacturing firm profits, extending earlier research by combining industry-level and firm-level measures of unionization. Using several profit measures, we find that quasi-rents from firm investments in intangible assets are a relatively greater source of union profit effects than product market concentration and that union profit effects occur largely in the first 10 percent of firm coverage, suggesting spillover effects on nonunion employees. 相似文献

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. 相似文献

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) 相似文献

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. 相似文献

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. 相似文献
