A theory of money needs a proper place for financial intermediaries. Intermediaries diversify risks and create inside money. In downturns, micro-prudent intermediaries shrink their lending activity, fire-sell assets and supply less inside money, exactly when money demand rises. The resulting...

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...

Motivated by empirical evidence, we propose an open-economy New Keynesian model with financial integration that allows financial intermediaries to hold foreign long-term bonds. We find financial integration features an amplification for a domestic monetary policy shock and a negative spillover...

In most countries, equity is a cheap source of funding for a country's largest financial institutions. 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...

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...
