Motivated by the findings that the aggregate (discretionary) accruals positively predicts oneyear-ahead firm-level stock returns and that there is a considerable amount of co-movement in firm-level (discretionary) accruals, we decompose firm-level (discretionary) accruals into a market-wide component and a firm-specific component. We document robust evidence that the two orthogonal (discretiona...

We find that the positive relation between aggregate accruals and one-year-ahead market returns documented in Hirshleifer, Hou and Teoh [2009] is driven by discretionary accruals but not normal accruals. The return forecasting power of aggregate discretionary accruals is robust to choices of sample periods, return measurements, estimation methods, business condition and risk premium proxies, an...

The paper analyses the existence and efficiency of discretionary industrial assistance schemes under asymmetric information between an uninformed government and a uniform distribution of firms with differing productivities. Discretionary assistance allows the government to scrutinise projects in an effort to learn the type, which can reduce the ‘informational rents’ of automatic assistance, whe...

This paper develops a method based on data envelopment analysis (DEA) for efficiency assessments taking into account the effect of non-discretionary factors. A typology that classifies the non-discretionary factors into two groups is proposed: the factors that characterize the external conditions where the decision making units (DMUs) operate (external factors), and the factors that are interna...

This thesis examines anomalies related to the discretionary accruals usage during the tenures of CEOs in listed U.S. companies since the implementation of Sarbanes-Oxley Act. The approach used in this thesis is quantitative in nature. Four well-known discretionary accruals models: Healy model, DeAngelo model, Jones model and modified Jones are used in to separate discretionary accruals from the...

BACKGROUND The Health Star Rating (HSR) is an interpretive front-of-pack labelling system that rates the overall nutritional profile of packaged foods. The algorithm underpinning the HSR includes total sugar content as one of the components. This has been criticised because intrinsic sugars naturally present in dairy, fruits, and vegetables are treated the same as sugars added during food proce...

The behaviors of heavy vehicles drivers in mandatory and discretionary lane changes are analyzed in this paper. 640 mandatory and 2,035 discretionary lane change events were extracted from a naturalistic driving database. Variations in gap acceptance and lane change duration were investigated. Statistical analysis showed that mandatory lane changes are more aggressive in gap acceptance and lane...
