In this study, we find that product market competition gives rise to a higher stock crash risk for a large sample of international firms. However, country-level institutional quality, measured with a set of governance indices and the world-wide board reforms, weakens the positive relationship between product market competition and stock crash risk. With accruals quality and accounting conservatism as information hoarding proxies, we find that stock crash risk in competitive industries can be attributed to managerial incentive in withholding information (especially the bad news) and that institutional quality mitigates such incentive.
