Rather than focusing all attention on safety issues of working faces, supervising departments of coalmines are advised to pay much more attention to institutional factors that may impact people’s attitude and behavior, which are responsible for most coalmine accidents. It is believed that such a shift of attention can effectively reduce coalmining production accidents and greatly enhance supervision efficacy.展开更多

Financial reporting is a main component of them, being the basis for information necessary to investors＇ decisions. Managers have a chance to manipulate information provided in financial statements, in order to offer a better image of a firm to its potential and effective investors. The objective of this study is to evaluate the possibility of detecting extreme cases of earnings management and to check the predictive ability of the discretionary accruals models on the event of fraudulent earnings restatement. Through the abuse of reporting incentives, a manager gives out false information that should be averted and punished by regulators in a fair market system. The authors check the efficacy of different earnings management detection models in predicting discretionary manipulations and study the correlation between the frequency of manipulation and the event of fraud.展开更多
