June 2009Crash Risk in Currency Markets
with Emmanuel Farhi, Samuel Paul Fraiberger, Xavier Gabaix, Adrien Verdelhan: w15062
Since the fall of 2008, option smiles have been clearly asymmetric: out-of-the-money currency options point to large expected exchange rate depreciations (appreciations) for high (low) interest rate currencies, suggesting that disaster risk is priced in currency markets. To study the price of disaster risk, we propose a simple structural model that includes both Gaussian and disaster risk and can be estimated even in samples that do not contain disasters. Estimating the model over the 1996 to 2011 period using exchange rate spot, forward, and option data, we obtain a real-time index of world disaster risk premia. We find that disaster risk accounts for more than a third of currency risk premia in advanced countries over the period.
December 2006Decomposing the Effects of Financial Liberalization: Crises vs. Growth
with Aaron Tornell, Frank Westermann: w12806
We present a new empirical decomposition of the effects of financial liberalization on economic growth and on the incidence of crises. Our empirical estimates show that the direct effect of financial liberalization on growth by far outweighs the indirect effect via a higher propensity to crisis. We also discuss several models of financial liberalization and growth whose predictions are consistent with our empirical findings.

May 2006Exchange Rate Volatility and Productivity Growth: The Role of Financial Development
with Philippe Aghion, Philippe Bacchetta, Kenneth Rogoff: w12117
This paper offers empirical evidence that real exchange rate volatility can have a significant impact on long-term rate of productivity growth, but the effect depends critically on a country%u2019s level of financial development. For countries with relatively low levels of financial development, exchange rate volatility generally reduces growth, whereas for financially advanced countries, there is no significant effect. Our empirical analysis is based on an 83country data set spanning the years 1960-2000; our results appear robust to time window, alternative measures of financial development and exchange rate volatility, and outliers. We also offer a simple monetary growth model in which real exchange rate uncertainty exacerbates the negative investment effects of domestic credit market co...

January 2005Systemic Crises and Growth
with Aaron Tornell, Frank Westermann: w11076
In this paper, we document the fact that countries that have experienced occasional financial crises have, on average, grown faster than countries with stable financial conditions. We measure the incidence of crisis with the skewness of credit growth, and find that it has a robust negative effect on GDP growth. This link coexists with the negative link between variance and growth typically found in the literature. To explain the link between crises and growth we present a model where contract enforce-ability problems generate borrowing constraints and impede growth. In the set of financially liberalized countries with a moderate degree of contract enforceability, systemic risk-taking relaxes borrowing constraints and increases investment. This leads to higher mean growth, but also to gre...
