We use institutional-related theories and a unique natural experiment that enables an exogenous test of the influence of controlling shareholders on managerial accountability to corporate fraud. In China, prior to the Split Share Structure Reform (SSSR), state shareholders held restricted shares that could not be traded. This restriction mitigated state-owned enterprise controlling shareholders' incentives to monitor managers. The data examined show the SSSR strengthens incentives of stateowned enterprise controlling shareholders to replace fraudulent management. Our findings support the view that economic incentives are important to promote corporate governance and deter fraud.
