Since the 2008 global financial crisis, and after decades of relative neglect, the importance of the financial system and its episodic crises as drivers of macroeconomic outcomes has attracted fresh scrutiny from academics, policy makers, and practitioners. Theoretical advances are following a...

How much of carry trade excess returns can be explained by the presence of disaster risk? To answer this question, we propose a simple structural model that includes both Gaussian and disaster risk premia and can be estimated even in samples that do not contain disasters. The model points to a...

Can banks maintain their advantage as liquidity providers when they are heavily exposed to a financial crisis? The standard argument - that banks can - hinges on deposit inflows that are seeking a safe haven and provide banks with a natural hedge to fund drawn credit lines and other commitments....

We study interventions to restore efficient lending and investment when financial markets fail because of adverse selection. We solve a design problem where the decision to participate in a program offered by the government can be a signal for private information. We charac terize optimal...

We explore a view of the crisis as a shock to investor sentiment that led to the collapse of a bubble or pyramid scheme in financial markets. We embed this view in a standard model of the financial accelerator and explore its empirical and policy implications. In particular, we show how the...

A regulator resolving a bank faces two audiences: depositors, who may run if they believe the regulator will not provide capital, and banks, which may take excess risk if they believe the regulator will provide capital. When the regulator's cost of injecting capital is private information, it...

This paper makes a case that the global imbalances of the 2000s and the recent global financial crisis are intimately connected. Both have their origins in economic policies followed in a number of countries in the 2000s and in distortions that influenced the transmission of these policies...

This paper builds a dynamic general equilibrium macro-finance model with two types of borrowers: entrepreneurs who want to produce and gamblers who want to play a lottery. It links central bank's interest rate policy to expected cash flows of both types. This link enables us to study how the...

This Paper develops a test of contagion in financial markets based on bivariate correlation analysis, which generalizes existing tests, and applies it to the international effects of the Hong Kong stock market crisis of October 1997. Contagion is defined as a structural break in the...

High frequency arbitrage opportunities arise when the price of one asset follows, with a lag, changes in the value of another related asset due to information arrival. These opportunities are toxic because they expose liquidity suppliers to the risk of being picked off by arbitrageurs. Hence,...
