Mayor re-election and earnings management: evidence from Portuguese municipalities

Purpose - The aim of this paper is to investigate whether Mayors in Portugal engage in earnings management close to zero with the motivation of re-election. Design/methodology/approach - The data used in this study were annual financial information from Portuguese municipalities from 2005 to 2016, as well as data on elections and Mayor re-elections involving three political cycles. The methodologies employed were quantitative, including graphical and panel data regressions. Findings - The results indicate that municipalities used discretionary accruals to engage in earnings management to report net earnings close to zero, and re-election seems to be a motivation for earnings management behaviour. Furthermore, the results suggest that municipalities in which the Mayor is re-elected are less likely to report positive net earnings close to zero. Originality/value - This paper makes a valuable contribution to the literature on earnings management in municipalities. At the theoretical level, it makes it possible to identify whether re-election is a motivation for earnings management and, in this sense, to identify patterns of behaviour by managers. On a practical level, the knowledge of a manager's behaviour patterns will help to anticipate his or her future behaviour and, consequently, may prevent inefficiencies.
