FACULTÉ & RECHERCHE

This paper studies whether government’s participation in product market, as a customer, affects supplier firms’ stock price crash risk. Using a sample of U.S. firms from 1980 to 2015, we find robust evidence that the presence of major government customers is associated with a lower level of stock price crash risk for supplier firms. Further, we show that government customers can lower suppliers’ crash risk by imposing monitoring activities on suppliers and/or reducing suppliers’ operational risk, leading to a reduction in supplier managers’ bad news hoarding behavior. Overall, our results indicate that government spending, as an important public policy, can significantly affect shareholders’ value by mitigating stock price crash risk.
