Trade networks and economic fluctuations in Asian countries

The paper presents a new methodology, based on tensor decomposition, to map dynamic trade networks and to assess its strength in forecasting economic fluctuations at different periods of time in Asia. Using the monthly merchandise import and export data across 33 Asian economies, together with the US, EU and UK, we detect the community structure of the evolving network and we identify clusters and central nodes inside each of them. Our findings show that data are well represented by two communities, in which People's Republic of China and Japan play the major role. We then analyze the synchronisation between GDP growth and trade. Furthermore we apply our model to the prediction of economic fluctuations. Our findings show that the model leads to an increase in predictive accuracy, as higher order interactions between countries are taken into account.     

The Market's Assessment of the Financial Services Modernization Act of 1999

We examine the impact of the events leading up to and including the passage of the Financial Services Modernization Act (FSMA) of 1999 on the stock returns of banks, brokerage firms, and insurance companies. We find that the impact is positive for all institutions. Bank gains are positively related to size and capitalization. Brokerage firms gain regardless of size, but the gains are inversely related to capitalization and insurance companies gain regardless of size or capital position. The strong positive reaction suggests that the market expects the institutions to benefit from the new opportunities created by the FSMA's passage.

美国Sarbanes-Oxley Act对会计的治理及其启示

为加强对会计的治理,美国出台并通过了SOX Act,该法案对加强注册会计师行业管理、提高注册会计师的独立性、完善会计信息披露制度等方面作出了详细规定.对于国内注册会计师行业治理而言,在继续加强行业自律的同时,借鉴美国的做法,加大对注会行业的外部监管力度,采取有效措施提高注册会计师的独立性,继续坚持以基本原则为基础的准则制订方针,增加披露表外信息、非财务信息等信息内容等.     

《萨班斯法案》孰是孰非:基于成本与效率(收益)的分析视角

《萨班斯法案》的出台堪称注册会计师行业的一件大事，从理论上看，该法案各项条款的出台确实具有积极的意义，但仍然存在缺陷，它更多地强调监管的作用，而监管的效率往往不如制衡的效率；它更多地强调经济处罚和刑事处罚的作用，而这两种处罚却必须以民事赔偿为前提，并最终使作假行为的作假成本大大高于作假收益。

Camouflaged Indicators of Earnings Management†

Abstract

We argue that, in response to increased scrutiny and greater attention to accruals versus sales, firms become more likely to engage in accrual conversion (AC) cash management aimed at aligning cash and accruals with earnings and sales (e.g. by factoring of receivables). In doing so, they reduce the statistical power of standard indicators of accrual-based earnings management – in effect, camouflaging their earnings management activity. This proposition is of interest because many influential papers on earnings management have utilized accrual-based indicators to reach their conclusions. Our results indicate that firms indeed became more likely to engage in AC cash management after the passage of the Sarbanes-Oxley Act (SOX), and that this tendency was particularly pronounced among firms with strong incentives (or enhanced ability) to perform and hide earnings management. In particular, our findings suggest that the post-SOX decrease in standard measurements of accrual-based earnings management, identified in prior research, is partially attributable to firms’ increased engagement in AC cash management activity.

Employer Penalties for Failure to Provide Individual Employee Notification Under the Family and Medical Leave Act: “Clarifications” Following Ragsdale v. Wolverine Worldwide, Inc.

This article examines the Supreme Court's ruling in Ragsdale v. Wolverine Worldwide, Inc. (2002) and considers its implications for employer and employee rights and responsibilities relative to implementing the FMLA policies. We provide an overview of the pre-decision regulatory environment including the general leave provisions of the FMLA and DOL's regulations requiring employer notification of leave designated as FMLA leave. We also identify those provisions that the decision did not alter and provide a broader consideration of the issues and implication of this decision for employers and employees.
