We develop a theory of optimal financing for R&D-intensive firms that uses their unique features—large capital outlays, long gestation periods, high upside, and low probabilities of R&D success—that explains three prominent stylized facts about these firms: their relatively low use of debt,...

Several past studies have found health risk to be negatively correlated with the probability of voluntary health insurance. This is contrary to what one would expect from standard textbook models of adverse selection and moral hazard. The two most common explanations to the counter-intuitive...

In an integrated world capital market with perfect information, all forms of capital flows are indistinguishable. Information frictions and incomplete risk sharing are important elements that needed to differentiate between equity and debt flows, and between different types of equities. This...

We analyze a model of informed trading where an activist shareholder accumulates shares in an anonymous market and then expends costly effort to increase the firm value. We find that equilibrium prices are affected by the position accumulated by the activist, because the level of effort...

This paper applies direct tests for adverse selection and moral hazard in the market for child care. A unique data set containing quality measures of various characteristics of child care provided by 746 rooms in 400 centers, as well as the evaluation of the same attributes by 3,490 affiliated...

This paper tests for asymmetric information in the U.K. annuity market of the 1990s by trying to identify 'unused observables,' attributes of individual insurance buyers that are correlated both with subsequent claims experience and with insurance demand but that insurance companies did not use...

This paper develops a model to study how entrepreneurs and venture-capital investors deal with moral hazard, effort provision, asymmetric information and hold-up problems. We explore several financing scenarios, including first-best, monopolistic, syndicated and fully competitive financing. We...

We derive testable implications of model in which first best allocations are not achieved because of a moral hazard problem with hidden saving. We show that in this environment agents typically achieve more insurance than that obtained under autarchy via saving, and that consumption allocation...

It is by now well-known that, in the presence of moral hazard or adverse selection, randomization of insurance premia and benefits may be Pareto efficient. This paper: i) provides a typology of the various forms that randomization may take; ii) derives necessary and/or sufficient conditions for...

This paper uses an asymmetric information framework to understand the causes of the recent financial crisis in Korea. It shows that the Korean data is consistent with this explanation of the crisis. It then draws on this analysis to discuss several lessons that can help guide Korean policymakers...
