Theory predicts that information sharing among lenders attenuates adverse selection and moral hazard, and can therefore increase lending and reduce default rates. To test these predictions, we construct a new international data set on private credit bureaus and public credit registers. We find...

We analyze contagious sovereign debt crises in financially integrated economies. Under financial integration banks optimally diversify their holdings of sovereign debt in an effort to minimize the costs with respect to an individual country's sovereign debt default. While diversification...

This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...

On May 9, 2010 euro zone countries announced the creation of the European Financial Stability Facility as a response to the sovereign debt crisis. This paper investigates the impact of this announcement on bank share prices, bank CDS spreads and sovereign CDS spreads. The main private...

Crowding-out during the British Industrial Revolution has long been one of the leading explanations for slow growth during the Industrial Revolution, but little empirical evidence exists to support it. We argue that examinations of interest rates are fundamentally misguided, and that the...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value added output, we calculate for each state the efficient frontier for investments in the real economy, the efficient Sharpe...

I propose a simple theory of intertwined business and financial cycles, where financial regulation both optimally responds to and influences the cycles. In this model, banks do not internalize the effect of their credit expansion on other banks’ expected bankruptcy costs, which leads to...

We examine the pricing of financial crash insurance during the 2007-2009 financial crisis in U.S. option markets. A large amount of aggregate tail risk is missing from the price of financial sector crash insurance during the financial crisis. The difference in costs of out-of-the-money put...

This paper examines the quality of credit ratings assigned to banks in Europe and the United States by the three largest rating agencies over the past two decades. We interpret credit ratings as relative assessments of creditworthiness, and define a new ordinal metric of rating error based on...

The paper establishes that sovereigns, like banks, need a lender of last resort (LoLR). In the euro area the ECB, with its estimated €3.4 trillion non-inflationary loss absorption capacity, is the only credible sovereign LoLR. The ECB/Eurosystem has been acting as sovereign LoLR through its...
