This paper proposes an explanation of the shifts in the volatility of exchange rate returns that relies on standard present value exchange rate models. Agents are uncertain about the true data generating model and deal with the model uncertainty by making inference on the models and their...

This paper studies the role of financial frictions in explaining the heterogeneous effect of exchange rate uncertainty on international trade. Empirically, exports in industries in which firms have less tangible capital or rely more heavily on external finance decrease more in times of high...

This paper examines the effects of time-varying volatility on welfare. I construct a tractable endogenous growth model with recursive preferences, stochastic volatility, and capital adjustment costs. The model shows that a rise in volatility can decelerate growth in the absence of any level...
