Credit market freezes in which debt issuance declines dramatically and market liquidity evaporates are typically observed during financial crises. In the financial crisis of 2008-09, the structured credit market froze, issuance of corporate bonds declined, and secondary credit markets became...

Monetary policy shocks have a large impact on stock returns in narrow windows around press releases by the Federal Reserve. We use spatial autoregressions to decompose the overall effect of monetary policy shocks into a direct effect and an indirect (network) effect. We attribute 50%-85% of the...

We analyze the empirical determinants of liquidity in debt markets in light of predictions stemming from debt-based information theories. We conduct a battery of tests confirming predictions of asymmetric information models of bond liquidity, including those that predict a``hockey-stick"...

We study the Rothschild-Stiglitz model of competitive insurance markets with endogenous information disclosure by both firms and consumers. We show that an equilibrium always exists, (even without the single crossing property), and characterize the unique equilibrium allocation. With two types...
