An enduring puzzle is why credit ratings are coarse indicators of issuer credit quality, with a relatively small number of ratings categories being used to describe credit qualities that lie in a continuum. We develop a theoretical model to explain why ratings are coarse even though coarseness...

We develop a theory of optimal financing for R&D-intensive firms. With only market financing, the firm relies exclusively on equity financing and carries excess cash, but underinvests in R&D. We use mechanism design to examine how intermediated financing can attentuate this underinvestment. The...

We develop a structural model to quantitatively analyze the effects of asymmetric beliefs and agency conflicts on capital structure. Capital structure reflects the dynamic tradeoff between the positive incentive effects of managerial optimism and the negative effects of risk-sharing costs....

An enduring puzzle is why credit rating agencies (CRAs) use a few categories to describe credit qualities lying in a continuum, even when ratings coarseness reduces welfare. We model a cheap-talk game in which a CRA assigns positive weights to the divergent goals of issuing firms and investors....

We present a dynamic model of an IPO market in which firms go public to raise capital for investment. The original shareholders have inside information with respect to the quality of their firm's investment opportunities, and they decide whether to go public, how much capital to raise and...

The search of valuable investment opportunities is one of the fundamental responsibilities of corporate managers. Existing studies of this search process usually model the investment opportunity as a binary signal and the role of the manager ends when such signal arrives. This paper studies a...

We offer a model in which sequences of individuals often converge upon poor decisions and are prone to fads, despite communication of the payoff outcomes from past choices. This reflects both direct and indirect action-based information externalities. In contrast with previous cascades...

Moral hazard and disagreement are important economic frictions. How do their individual effects on economic behavior differ and how do these frictions interact when operating together? This paper addresses these questions by developing a canonical model of disagreement (generated by...

This paper analyzes the effects of the way information is produced and transmitted through an organizational structure on the business dynamics of a firm. Specifically, I study its effects on the agency problem, concluding that it proves to be an efficient and effective solution to overcome the...
