We present a model to study the dynamics of risk premia during crises in asset markets where the marginal investor is a financial intermediary. Intermediaries face a constraint on raising equity capital. When the constraint binds, so that intermediaries' equity capital is scarce, risk premia...

We find that shocks to the equity capital ratio of financial intermediaries--Primary Dealer counterparties of the New York Federal Reserve--possess significant explanatory power for crosssectional variation in expected returns. This is true not only for commonly studied equity and government...

Banks are optimally opaque institutions. They produce debt for use as a transaction medium (bank money), which requires that information about the backing assets - loans - not be revealed, so that bank money does not fluctuate in value, reducing the efficiency of trade. This need for opacity...

This paper examines the structure, behavior and performance of the N95 respirator market in the U.S. before and during the COVID-19 pandemic (2020-early 2022). It focuses on the behavior and performance of government and private sector organizations in the allocation of scarce supplies of N95...

Public-private partnerships (PPPs) have emerged as a new organizational form to provide public infrastructure over the last 30 years. Governments find them attractive because PPPs can be used to avoid fiscal check-and-balances and increase spending. At the same time, PPPs can lead to important...

This paper summarizes economic research on investment in public infrastructure and introduces the findings of several new studies on this topic. It begins with a review of several potential justifications for the public sector's involvement in building, financing, and operating infrastructure,...

We present a model of public procurement in which both contractual flexibility and political tolerance for contractual deviations determine renegotiations. In the model, contractual flexibility allows for adaptation without formal renegotiation while political tolerance for deviations decreases...

Public-private partnerships (PPPs) are increasingly used to provide infrastructure services. Even though PPPs have the potential to increase efficiency and improve resource allocation, contract renegotiations have been pervasive

We offer empirical information on the correlates of commercialization activity for research projects funded through the U.S. National Institutes of Health's (NIH's) Small Business Innovation Research (SBIR) award program. Based on this analysis we suggest possible recommendations for improving...

Public-private partnerships (PPPs) cannot be justified because they free public funds. When PPPs are justified on efficiency grounds, the contract that optimally balances demand risk, user-fee distortions and the opportunity cost of public funds, features a minimum revenue guarantee and a...
