This study investigates the effect of procrastination on academic performance. Prior research has often relied upon self-reported measures of procrastination, which are only weakly correlated with actual procrastination. We use the start and submission of a set of online homework problems as two objective, direct measures of student procrastination and the grade on the assignments as a measure of performance. In our study, there were a number of potential benefits to submitting online assignments ‘just-in-time’. Thus, there was a direct benefit to procrastination, which students had to weigh against potential drawbacks. With a sample size larger than those previously reported in the literature, we find that for both procrastination measures, task procrastination is associated with lower task performance. To ensure that our results are not just an association between performance and student quality, we test for the association between task procrastination and task performance, while controlling for student quality. We find that even after controlling for student quality, task procrastination is associated with lower task performance.  相似文献

Summary. We report a policy experiment that illustrates a potential problem of using historical pass-through rates as a means of predicting the competitive consequences of projected firm-specific cost savings in antitrust contexts, particularly in merger analysis. The effects of cost savings on welfare can vary vastly, depending on how the savings affect the industry supply schedule. In a capacity-constrained price-setting oligopoly, we observe that cost savings can overwhelm behaviorally salient market power incentives when the savings affect marginal (high cost) units. However, cost savings of the same magnitude on an infra-marginal unit leave market power unchanged.  相似文献

Input substitution theoretically invalidates the resource flow predictions of effective rates of protection calculated in a partial equilibrium framework. Partial equilibrium effective protection analysis, despite this "substitution problem," has nevertheless quietly settled into the trade economistÕs toolbox. This paper presents a new, transparent review of the substitution problem in effective protection. It finds that partial equilibrium effective protection analysis, although theoretically susceptible to misleading results, is in practice a reasonable estimator of certain short-run general equilibrium effects of protection.  相似文献

Capital management by mutual financial institutions (such as credit unions) provides a valuable testing ground for assessing the impact of capital regulation and theories of managerial behaviour in financial institutions. Limited access to external equity capital means that capital accumulation must be met primarily by reliance on retained earnings. To deal with shocks to the capital position and avoid breaching regulatory requirements, managers will aim to have a buffer of capital in excess of the regulatory minimum. Moreover, mutual governance arrangements and an absence of capital market discipline mean that managers have discretion to set target capital ratios which differ significantly from industry averages. This paper develops a formal model of capital management and risk management in mutual financial institutions such as credit unions which reflects these industry characteristics. The model is tested using data from larger credit unions in Australia, which have been subject to the Basel Accord Risk Weighted Capital Requirements since 1993. The data supports the hypothesis that credit unions manage their capital position by setting a short term target profit rate (return on assets) which is positively related to asset growth and which is aimed at gradually removing discrepancies between the actual and desired capital ratio. Desired capital ratios vary significantly across credit unions. There is little evidence of short run adjustments to the risk of the asset portfolio to achieve a desired capital position.  相似文献

The natural gas transmission industry, once paternalistic towards its employees, is feeling the effects of challenges to the doctrine of employment at will, and is responding with policies that will increase managerial prerogatives. This article approaches the issue from the points of view both of law and of economics, and includes a survey of pipeline managers who must develop viable work rules in an environment of increasing expectations of employee rights and tightening market competition.  相似文献

This study statistically analyzes two-year college students' attitudes toward cheating via a survey containing academic and business situations that the students evaluated on a seven point scale from unethical to ethical. When both the general questions concerning attitudes about cheating and the opinions on the ethical statements are considered, the business students were generally more unethical in their behavior and attitudes than non-business majors. These results indicate a need for more ethical exposure in business courses to help students distinguish ethical from unethical decisions.  相似文献
