基于资产质量的会计报表项目附注披露内容改进研究——兼谈可靠性与相关性

传统观念认为可靠性和相关性在大多数情况下此消彼长，不能同方向服务于会计信息使用者。但本文基于封相关性和可靠性关系的重新思考，认为相关性是封会计信息内容的要求，可靠性是封会计信息质量的要求，相关性必须与可靠性相结合才能有效地服务于会计信息使用者。本文以此为出发点，在简要探讨相关性内涵及其与可靠性之间关系的基础上，着重探讨相关性具体信息内容，并主要以资产负债表项目附注披露内容为研究对象，建议改进应收款项、存货、长期股权投资、固定资座、在建工程和无形资产等部分报表项目附注的披露内容，以反映企业资产的变现及预期收益能力，从而提高会计报表决策相关性。

An alternative interpretation of the discontinuity in earnings distributions

We show that the asymmetric effects of income taxes and special items for profit and loss firms contribute to a discontinuity at zero in the distribution of earnings. Income taxes draw profit observations towards zero while negative special items pull loss observations away from zero. These earnings components are thus expected to contribute to a discontinuity even in the absence of discretion. We show our results are not an artifact of deflation and that other common components of earnings do not have similar effects on the earnings distribution around zero.

A New Measure of Disclosure Quality: The Level of Disaggregation of Accounting Data in Annual Reports

We construct a new, parsimonious, measure of disclosure quality—disaggregation quality (DQ)—and offer validation tests. DQ captures the level of disaggregation of accounting data through a count of nonmissing Compustat line items, and reflects the extent of details in firms’ annual reports. Conceptually, DQ differs from existing disclosure measures in that it captures the “fineness” of data and is based on a comprehensive set of accounting line items in annual reports. Unlike existing measures, which are usually applicable for a subset of firms or are based on a subset of information items, DQ can be generated for the universe of Compustat industrial firms. We conduct three sets of validation tests by examining DQ's association with variables predicted by prior literature to be associated with information quality. DQ is negatively (positively) associated with analyst forecast dispersion (accuracy) and negatively associated with bid‐ask spreads and cost of equity. These associations continue to hold after we control for firm fundamentals. Taken together, results from this battery of validation tests are consistent with our measure capturing disclosure quality.
