This study investigates the scope of an audit conducted during the first part of the annual auditing cycle. It measures empirically the probability of auditing various balance sheet and income statement accounts. The results indicate that current assets and liabilities have a higher probability for an interim audit than fixed assets, long-term debt and equity accounts. Furthermore, the likelihood of including each account in an interim audit increases with client size, so the larger an auditee, the wider the audit scope during the beginning of the audit cycle. Also, the empirical results indicate that the lower the familiarity of the auditor with the auditee, the wider the scope of an interim audit. These results seem to be consistent with auditing theory and intuition. 相似文献

The intertemporal risk-return relation and investor behavior are both important pricing factors that jointly determine the expected market risk premium. Using the price adjustment process as a control variable, we find that the intertemporal risk-return relation is positive conditional on bad market news, but is non-positive conditional on good market news. This implies that good (bad) market news weakens (strengthens) the positive risk-return relation. The pattern in the distortion of the risk-return relation is consistent with short-term mispricing in which investors overvalue (undervalue) the stock market in reaction to good (bad) market news. We also show that ignoring the price adjustment process in the estimation of the risk-return relation leads to model misspecification and induces an upward (downward) bias in estimates of the relative risk aversion parameter conditional on good (bad) news. Our model of the asymmetric risk-return relation along with the price adjustment process is capable of generating the return dynamics that is attributable to technical trading profits. We suggest that the profitability of technical trading rules is not a violation of market efficiency, but a consequence of trading rules exploiting the asymmetric effect of price changes on the risk-return relation, along with the persistence property of price changes. 相似文献

Food Stamp Benefits and Child Poverty 总被引:2,自引:0,他引:2

In 2000, 8.8 million children lived in households participating in the Food Stamp Program, making this assistance program a crucial component of the social safety net. Despite its importance, little research has examined food stamps' effect on children's overall well-being. Using the Current Population Survey from 1989 to 2001, we consider the impact of food stamps on three measures of poverty—the headcount, the poverty gap, and the squared poverty gap. We find that in comparison to the headcount measure, food stamp benefits lead to large reductions in the poverty gap and squared poverty gap measures. 相似文献

This paper investigates causation contemporaneously and dynamically to elucidate the persistent lack of agreement about what "causes" changes in farmland prices. The analysis synthesizes and extends previous investigations in this area by employing a combination of directed acyclic graphs (DAG), a recently developed modeling technique, and cointegrated VAR model. DAG theory and algorithms offer a powerful tool for analyzing contemporaneous causal relationships among economic variables. The results from this study confirm the importance of measures of return to farming, financial (credit market constraints) and/or macroeconomic activity as significant determinants of fluctuations in farmland prices.
Le présent article examine la causalité de façon contemporaine et dynamique pour élucider le manque persistant de consensus quant aux causes de variations du prix des terres. L'analyse est une synthèse des études antérieures de même qu'un prolongement effectuéà l'aide d'une combinaison de graphes acycliques orientés (DAG), technique de modélisation mise au point récemment, et du modèle VAR cointégré. La théorie des DAG et les algorithmes constituent un outil puissant pour analyser les liens causals contemporains des variables économiques. Les résultats confirment l'importance du rendement de l'activité agricole, des contraintes financières (contraintes du crédit) et/ou de l'activité macroéconomique comme déterminants significatifs des variations du prix des terres agricoles. 相似文献

This paper investigates the role of the stock of unionized labor in determining equity investment risk. I estimate a labor stock measure based on expected compensation costs, and use the ratio of labor stock to total assets as a risk proxy. At the median, the labor stock is comparable in magnitude to total assets. Regression estimates show the associations between labor-based risk proxies and equity market risk measures are both economically and statistically significant. In addition, the labor-based measures provide risk information over and above information contained in standard risk proxies such as financial and operating leverage. 相似文献

International labour rights organisations pay considerable attention to the working conditions in less developed countries. For labour rights activists, labour standards such as collective bargaining rights and maternal leave promote economic progress. We argue that this perspective has the causation backwards and that it is economic development that causes the codification of improved working conditions. 相似文献

This article considers the outsourcing choice of a downstream firm with its own upstream production resources or assets. The novelty of the approach is to consider the outsourced function as involving resources consistent with the resource‐based view of the firm. From a bargaining perspective, we characterize a downstream firm's decision whether to outsource to an independent or to an established upstream firm. In so doing, the downstream firm faces a trade‐off between lower input costs afforded by independent competition, and higher resource value associated with those who can consolidate upstream capabilities. We show that this trade‐off is resolved in favor of outsourcing to an established firm. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Using longitudinal survey data collected in collaboration with a treatment program, this paper estimates the economic impacts of antiretroviral treatment. The responses in two outcomes are studied: (1) labor supply of treated adult AIDS patients; and (2) labor supply of individuals in patients' households. Within six months after treatment initiation, there is a 20 percent increase in the likelihood of the patient participating in the labor force and a 35 percent increase in weekly hours worked. Young boys in treated patients' households work significantly less after treatment initiation, while girls and adult household members do not change their labor supply. 相似文献
