Earnings management in times of natural disasters

Purpose - The main purpose of this study is to examine the determinants of firms’ earnings management (EM) activities during natural disasters, specifically the 2011 floods in Thailand. The motivation for conducting this study is that although disasters stem from natural processes, such events affect firms’ actions, resulting in adverse economic and social outcomes. Design/methodology/approach - Based on data from listed companies in Thailand and using a sample of 5,786 firm-year observations from 2008 to 2013, this study uses the differences-in-differences method to estimate the relation between earnings quality (EQ) and floods. Additionally, this study uses the same research design to observe how fast firms engage in EM, as reflected by the trends in EQ following the floods. Findings - This study finds that firms engage in EM to increase their earnings numbers and misrepresent their performance after experiencing the 2011 floods in Thailand. The evidence is consistent with the hypothesis that natural disasters are related to EQ. In addition, this study finds that firms’ responses are observed only in the year after the floods (2012). Originality/value - This study contributes to the literature on EM and quality in two ways. First, this study provides new evidence that during crisis situations such as natural disasters, firms strive to signal good news to capital markets, consistent with the market expectation hypothesis. Second, this study shows that natural disasters are as useful and equal as other exogenous shocks such as financial crises for economic research.
