On the Relation between Conservatism in Accounting Standards and Incentives for Earnings Management

Abstract

This paper studies the role of conservative accounting standards in alleviating rational yet dysfunctional unobservable earnings manipulation. We show that when accounting numbers serve both the valuation role (in which potential investors use accounting reports to assess a firm's expected future payoff) and the stewardship role(in which current shareholders rely on the same reports to monitor their risk-averse manager), current firm owners have incentives to engage in earnings management. Such manipulation reduces accounting numbers' stewardship value and leads to inferior risk-sharing. We then show that risk-sharing, and hence contract efficiency, can be improved under a conservative accounting standard where, absent earnings management, accounting earnings represent true economic earnings with a downward bias, compared to under an unbiased standard where, absent earnings management, accounting earnings represent true economic earnings without bias.
