This paper analyzes dynamic equilibrium risk sharing contracts between profit-maximizing intermediaries and a large pool of ex-ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex-post. In any given period, after having observed her income, the agent...

Empirical examinations of capital structure have led some to conclude that firms are under-levered. Implicit in this argument and much of the empirical work on leverage is the assumption that the availability of incremental capital depends solely on the risk of the firm's cash flows and...

This paper examines the impact of bank regulations, market structure, and national institutions on bank net interest margins and overhead costs using data on over 1,400 banks across 72 countries while controlling for bank-specific characteristics. The data indicate that tighter regulations on...

Do efficient financial markets and institutions promote economic growth? Have they done so in the past? In this essay, to be included in the Handbook of Finance and Development (edited by Thorsten Beck and Ross Levine), I survey a large and diverse historical literature that explores the...

On average, the stocks of the top 10% financial companies in a country account for over a quarter of total market capitalization, but these stocks earn returns that are significantly lower than...

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...

Financial institutions have both investors and customers. Investors, such as those who invest in stocks and bonds or private/public-sector guarantors of institutions, expect an appropriate risk-adjusted return in exchange for the financing and risk-bearing that they provide. Customers of a...

Can peer-to-peer lending (P2P) crowdfunding disintermediate and mitigate information frictions in lending such that choices and outcomes for at least some borrowers and investors are improved? I offer a framing of issues and survey the nascent literature on P2P. On the investor side, P2P...
