This paper studies how uncertainty about fundamentals contributed to currency crises from both a theoretical and an empirical perspective. We find evidence - based on a monthly dataset of Consensus forecasts for six Asian countries in the period January 1995-May 2001 - confirming the theoretical...

Abstracting from self-protection and self-insurance e ects of export produc-tion choices, exporting rms usually have access to a number of risk sharingmarkets that have an efficient risk management role. Two of the most strikingresults achieved from the existence of risk sharing markets are the...

In light of the recent discussion regarding the measurement of uncertainty and its impact on economic activity, this paper derives forward-looking measures of uncertainty and directional expectations for the CHF/EUR exchange rate based on over-the-counter option data and analyses its impact on...

When financial securities are modeled as claims on stochastic processes, each trader's beliefs at time can be summarized by a subjective probability distribution . The dominant Rational Expectations approach typically treats as a singleton that correctly gauges risks. In reality, financial risks...

Financial markets enable risk sharing and efficient allocation of capital. We characterize how these roles interact in a “feedback effects” model with diversely informed, risk-averse investors and a manager who learns from prices when making an investment decision. While learning from prices...

Recent empirical studies suggest that, during times of unexpected innovation, agents heterogeneously update their beliefs about an asset fundamental value, and they are uncertain about other agents' beliefs on it. In this paper I show that, when there is uncertainty about the market sentiment,...

Using the mutual fund industry as a laboratory, we demonstrate theoretically and empirically that economic policy uncertainty an affect investment decisions through an information rather than real options channel. Specifically, we find that fund flow-performance sensitivity decreases in...

The regulatory use of banks' internal models makes capital requirements more risk-sensitive but invites regulatory arbitrage. I develop a framework to study bank regulation with strategic selection of risk models. A bank supervisor can discourage arbitrage by auditing risk models, and implements...

We analyse the effect of the uncertainty about the fundamentals on the probability of sudden stops of capital flows from a theoretical and empirical perspective. Our model predicts that the probability of crises increases with the uncertainty, ie. the dispersion of private signals about the true...

This paper reconsiders a central bank's problem of determining rules for information dissemination and risk taking behavior that minimize the probability of currency crises. In a global games approach, we find that optimal transparency is adversely related to prior market beliefs. In countries...
