Romer, Co-Chair Two concerns in international economics motivate the essays. I. Does foreign trade harm or foster growth? Two essays look at this question from different perspectives. The first essay takes a dynamic general-equilibrium approach. Contrary to earlier partial-equilibrium models, the essay shows that trade can contribute to reducing the productivity gap between less developed and more advanced regions even if the advanced region hosts most of the innovative industries with dynamic externalities. Productivity may diverge in some cases. Even then both regions generally benefit more from trade than they lose. The second essay investigates microeconomic effects empirically. It analyzes the channels through which trade has induced productivity change in Brazil after the country liberalized its tariff act in 1990. The facilitated access to foreign inputs plays a minor role for productivity change. However, foreign competition pushes firms to raise efficiency markedly. Counterfactual simulations indicate that this competitive push is a salient source of immediate productivity change. In addition, the shutdown probability of inefficient firms rises with competition from abroad and exerts a positive 2 impact on aggregate productivity over time. II. What role does information play in financial markets? Evidence from financial crises suggests that investors possess information about troubled assets early on but do not act upon the information until a crisis looms. This behavior has consequences for the timing and prevention of crises. The two essays in this part introduce an integrated model of information acquisition and portfolio choice. The essays provide new tools for the analysis of information in financial markets, resolve a long-known no-equilibrium paradox, and clear the way for subsequent applied research into international financial crises. Employing different conjugate prior distributions, the essays demonstrate when investors value information and act on it. More information allows investors to select less risky portfolios. When the asset price is fully revealing, markets do provide information but less than socially desir- able. However, more information has a negative effect when becoming commonly known. Commonly shared information moves the asset price closer to the individually expected return, thus reducing the value of the risky asset. Professor Maurice Obstfeld, Co-Chair Professor David H.
