How does output-price stickiness affect managers’ incentive to manipulate earnings and their firms' financing costs? We show firms with sticky-output prices experience more negative returns during tight windows around the Enron scandal and are more likely to misreport earnings when securities regulation is lenient, and their misreporting drops significantly after regulation becomes stringent. Sticky-price firms also face improved credit-market conditions following securities regulation. We build a model of earnings manipulation with endogenous manipulation costs to rationalize our empirical findings. The study suggests firms' stickiness in product pricing facilitates insiders' selfinterested behavior, imposing agency costs on firms.
