This paper examines how the degree of competition among firms in an industry affects the optimal incentives that firms provide to their managers. A central assumption is that there is free entry and exit in the industry, which implies that changes in the nature of competition lead to changes in the equilibrium market structure. The main result is that as the intensity of product market competition increases (as a result of greater product substitutability or greater market size), principals unambiguously provide stronger incentives to their agents to reduce costs. At the same time, more intense competition also leads to more volatile firm-level profits. Consequently, managers’ incentives are positively correlated with firm-level risk, consistent with empirical evidence. A decrease in the cost of entering the market has the opposite effect on incentives, but still induces a positive correlation between risk and incentives.

Abstract We analyze how the availability of internal funds affects a firm's investment. We show that under fairly standard assumptions, the relation is U-shaped: investment increases monotonically with internal funds if they are large but decreases if they are very low. We discuss the tradeoff that generates the U-shape, and argue that models predicting an always increasing relation are based on restrictive assumptions. Using a large data set, we find strong empirical support for our predictions. Our results qualify conventional wisdom about the effects of financial constraints on investment behavior, and help to explain seemingly conflicting findings in the empirical literature.
