Unlike studies that estimate managerial bias, we utilize a direct measure of managerial bias in the U.S. insurance industry to investigate the effects of executive compensation and corporate governance on firms’ earnings management behaviors. We find managers receiving larger bonuses and stock awards tend to make reserving decisions that serve to decrease firm earnings. Moreover, we examine the monitoring effect of corporate board structures in mitigating managers’ reserve manipulation practices. We find managers are more likely to manipulate reserves in the presence of particular board structures. Similar results are not found when we employ traditional estimated measures of managerial bias.
