Predicting Earnings Management: The Case of Earnings Restatements

Abstract: This paper examines the usefulness of accounting information in predicting earnings management. We investigate a comprehensive sample of firms from 1971-2000 that restated annual earnings. We find that firms restating earnings have high market expectations for future earnings growth and have higher levels of outstanding debt. We also find that a primary motivation for the earnings manipulation is the desire to attract external financing at a lower cost. Furthermore, our evidence suggests that restating firms have been attempting to maintain a string of consecutive positive earnings growth and consecutive positive quarterly earnings surprises. Together, our evidence is consistent with capital market pressures acting as a motivating factor for companies to adopt aggressive accounting policies. Finally, we document that information in accruals, specifically, operating and investing accruals, are key indicators of the earnings manipulation that lead to the restatement. Collectively, the evidence suggests that market participants can gain substantial value from a careful consideration of information in financial statements.

Forecasting loads and prices in competitive power markets

Abstract: This paper provides a review of some of the main methodological issues and techniques which have become innovative in addressing the problem of forecasting daily loads and prices in the new competitive power markets. Particular emphasis is placed upon computationally intensive methods, including variable segmentation, multiple modeling, combinations, and neural networks for forecasting the demand side, and strategic simulation using artificial agents for the supply side.

Bankruptcy Codes and Innovation

Abstract: Do legal institutions governing financial contracts affect the nature of real investments in the economy? We develop a simple model and provide evidence that the answer to this question is yes. We consider a levered firm's choice of investment between innovative and conservative technologies, on the one hand, and of financing between debt and equity, on the other. Bankruptcy code plays a central role in these choices by determining whether the firm is continued or liquidated in case of financial distress. When the code is creditor-friendly, excessive liquidations cause the firm to shy away from innovation. In contrast, by promoting continuation upon failure, a debtor-friendly code induces greater innovation. This effect remains robust when the firm attempts to sustain innovation by reducing its debt under creditor-friendly codes. Employing patents as a proxy for innovation, we find support for the real as well as the financial implications of the model: (1) In countries with weaker creditor rights, technologically innovative industries create disproportionately more patents and generate disproportionately more citations to these patents relative to other industries; (2) This difference of difference result is further confirmed by within-country analysis that exploits time-series changes in creditor rights, suggesting a causal effect of bankruptcy codes on innovation; (3) When creditor rights are stronger, innovative industries employ relatively less leverage compared to other industries; and (4) In countries with weaker creditor rights, technologically innovative industries grow disproportionately faster compared to other industries. Finally, while overall financial development fosters innovation, stronger creditor rights weaken this effect, especially for highly innovative industries.

The Consequences of Mandatory Corporate Sustainability Reporting

Abstract: A key aspect of the governance process inside organizations and markets is the measurement and disclosure of important metrics and information. In this chapter, we examine the effect of sustainability disclosure regulations on firms’ disclosure practices and valuations. Specifically, we explore the implications of regulations mandating the disclosure of environmental, social, and governance (ESG) information in China, Denmark, Malaysia, and South Africa using differences-in-differences estimation with propensity score matched samples. We find that relative to propensity score matched control firms, treated firms significantly increased disclosure following the regulations. We also find increased likelihood by treated firms of voluntarily receiving assurance to enhance disclosure credibility and increased likelihood of voluntarily adopting reporting guidelines that enhance disclosure comparability. These results suggest that even in the absence of a regulation that mandates the adoption of assurance or specific guidelines, firms seek the qualitative properties of comparability and credibility. Instrumental variables analysis suggests that increases in sustainability disclosure driven by the regulation are associated with increases in firm valuations, as reflected in Tobin’s Q. Collectively, the evidence suggest that current efforts to increase transparency around organizations’ impact on society are effective at improving disclosure quantity and quality as well as corporate value.
