Latin American economies are exposed to ubstantial external vulnerability. Domestic imbalances and terms of trade shocks are often exacerbated by sudden financial distress. In this paper we explore ways of overcoming external vulnerability drawing lessons from a detailed comparison of the...

This paper investigates whether the presence of financial frictions can help explain the differences in the variability of output and inflation between the Pre- and the Post-Volcker periods. I use a limited participation model with credit market imperfections, in which financial frictions may...

Most work showing the yield curve predicts future economic growth relies on post WWII data. We demonstrate that the yield curve has predictive content for most of the post Civil War period. This predictive ability, however, is closely related to the credibility of the monetary regime in place,...

This paper revisits the Chilean experience with dollarization, indexation and nominalization in the 1958-2003 period. The purpose is to understand how Chile generally avoided dollarization and actually dedollarized in the 80s in order to draw some lessons for other countries. We find that many...

Financial dollarization has been placed at the forefront of the policy debate in many developing economies, for reasons that include its influence on inflation performance and, most prominently, the currency imbalance and associated financial fragility that it introduces for the economy as a...

A currency attack fails on its own when the speculator suffers from her financial problem. This paper extends the existing models and argues that the monetary authority?s willingness to peg and the speculator?s cost of attack are private information. Our model thus accounts for the duration of...

The fact that the expected payoffs on assets and call options are infinite under most log-stable distributions led Paul Samuelson and Robert Merton to conjecture that assets and derivatives could not be reasonably priced under these distributions, despite their many other attractive features....

The phenomenon of "choice shifts" in group decision-making is fairly ubiquitous in the social psychology literature. Faced with a choice between a ``safe" and ``risky" decision, group members appear to move to one extreme or the other, relative to the choices each member might have made on her...

We develop a Savage-type model of choice under uncertainty in which agents identify uncertain prospects with subjective compound lotteries. Our theory permits issue preference; that is, agents may not be indifferent among gambles that yield the same probability distribution if they depend on...

This paper investigates the uncertainty in variance and covariance of asset returns. It is commonly believed that these second moments can be estimated very accurately. However, time varying volatility and nonnormality of asset returns can lead to imprecise variance estimates. Using CRSP value...
