Agency conflicts and short- versus long-termism in corporate policies

Erwan Morellec

We build a dynamic agency model in which the agent controls both current earnings via short-term investment and firm growth via long-term investment. Under the optimal contract, agency conflicts can induce short- and long-term investment levels beyond first best, leading to short- or long-termism in corporate policies. The paper analytically shows how firm characteristics shape the optimal contract and the horizon of corporate policies, thereby generating a number of novel empirical predictions on the optimality of short-versus long-termism. It also demonstrates that combining short- and long-term agency conflicts naturally leads to asymmetric pay-for-performance in managerial contracts. (C) 2019 Elsevier B.V. All rights reserved.

Short-term debt and incentives for risk-taking

Erwan Morellec, Francesca Maria Zucchi

We challenge the view that short-term debt curbs moral hazard and demonstrate that, in a world with financing frictions and fair debt pricing, short-term debt generates incentives for risk-taking. To do so, we develop a model in which firms are financed with equity and short-term debt and cannot freely optimize their default decision because of financing frictions. We show that when firms are close to distress, the dynamic interaction of operating and rollover losses fuels default risk. In such instances, shareholders find it optimal to increase asset risk to improve interim debt repricing and prevent inefficient liquidation. These risk-taking incentives do not arise when debt maturity is sufficiently long. (C) 2020 Elsevier B.V. All rights reserved.

Product Market Competition and Option Prices

Erwan Morellec

Most firms face some form of competition in product markets. The degree of competition a firm faces feeds back into its cash flows and affects the values of the securities it issues. Through its effects on stock prices, product market competition affects the prices of options on equity and leads to an inverse relationship between equity returns and volatility, generating a negative volatility skew in option prices. Using a large sample of U.S. equity options, we provide empirical support for this finding and demonstrate the importance of accounting for product market competition when explaining the cross-sectional variation in option skew.
