This article provides new evidence on the effect of changes in employment protection on worker absence. We use novel multi‐organization data to examine changes in worker absence as workers move from temporary to permanent employment contracts. We demonstrate a robust positive effect of employment protection on sickness absence. It has also been suggested that the impact of employment protection on absence and effort is due to a fear of dismissal. We also provide evidence that suggests that temporary workers' absence is influenced by incentives to attain jobs with protection that is unrelated to threat of dismissal. This has not been considered in earlier research. This channel of employment protection effects has important policy implications.  相似文献

Although there has been significant interest among researchers in audit-quality-threatening behaviours (QTBs), the decision process through which staff auditors engage in those behaviours has received relatively little attention. It seems likely that the ethical intensity of the behaviours perceived by auditors may play an important role in that process; to date, this has not been tested. This study examines the mediating role of perceived ethical intensity in the relationship between perceived ethical culture of the firm and the auditors' ethical evaluation of, and intention to engage in, three different forms of QTBs. A multi-item measure of ethical intensity is developed and the findings provide the first empirical evidence of a direct relationship between perceived ethical intensity and ethical decision-making regarding QTBs. Moreover, the findings show that perceived ethical intensity fully mediates the relationship between perceived ethical culture and ethical decision-making. Implications of the findings for accounting firms and for researchers are discussed and areas for future research on the mediating role of perceived ethical intensity are suggested in the paper.  相似文献

Abstract

In recent years, the validity of the weak form efficient market hypothesis (EMH) has been called into question as several studies have uncovered evidence that technical trading rules have predictive ability with respect to both developed and emerging stock market indices. This study analyses the forecasting power of 2 of the most popular trading rules using index data for a selection of 11 European stock markets over the January 1991 to December 2000 period. The findings indicate that the emerging markets included in this paper are informationally inefficient; these markets displayed some degree of predictability in their share returns, although the developed markets did not. Furthermore, the results point to large differences in the performance of the rules examined; while small size filters consistently outperformed the buy-and-hold strategy in the emerging markets examined even after the consideration of transaction costs, the performance of the moving average rules was erratic and varied dramatically from market to market.  相似文献

The frequency and opportunity for unethical behavior by MIS professionals is examined empirically. In addition, the importance of top management's ethical stance, one's sense of social responsibility and the existence of codes of ethics in determining perceptions of the frequency and opportunity for unethical behavior are tested.Results indicate that MIS professionals are perceived as having the opportunity to engage in unethical practices, but that they seldom do so. Additionally, successful MIS professionals are perceived as ethical. Finally, while company codes of ethics were uncommon, top management was seen as supporting high ethical standards. Scott J.

Spatial disparity in incomes and productivity is apparent acrossand within countries. Most studies of the determinants of suchdifferences focus on cross-country comparisons or location choiceamong firms. Less studied are the large differences in agriculturalproductivity within countries related to concentrations of ruralpoverty. For policy, understanding the determinants of thisgeography of agricultural productivity is important, becausestrategies to reduce poverty often feature components designedto boost regional agricultural incomes. Census and endowmentdata for Ecuador are used to estimate a model of endogenoustechnology choice to explain large regional differences in agriculturaloutput and factor productivity. A composite-error estimationtechnique is used to separate systemic determinants from idiosyncraticdifferences. Simulations are employed to explore policy avenues.The findings suggest a differentiation between the types ofpolicies that promote growth in agriculture generally and thosethat are more likely to assist the rural poor.  相似文献
