International Economics

Spencer Family Professor of Economics, Professor

My primary research interests focus on the intersection of international trade and environmental economics. I study how firm-level responses to trade liberalization and to environmental regulation have contributed to the decline in the emission intensity of the manufacturing sector that has been observed in most advanced economies, how environmental regulations have affected the international competitiveness of exporters, and how international trade and economic growth interact in determining cross-country differences in pollution.

Research Chair, Associate Professor

My research interests are in the field of International Trade. In particular, I specialize in settings with firm heterogeneity and variable market power with applications to gains from trade, various industrial policies, regional trade agreements, and the determinants of firm and industry-level productivity.

Chair of Graduate Studies, Professor

My research interests are in many areas of macroeconomics, monetary economics and their intersections with international economics and development. My recent interests lie in understanding the economics of sovereign defaults and the government sector more generally with an emphasis on the role of institutions and political economy. My earlier work was more focused on business cycles in closed and open economies.

Chair, Associate Professor

My research has focused on understanding business cycle fluctuations. In my work, I use dynamic stochastic general equilibrium models to look for macroeconomic shocks and propagation mechanisms that help theoretical models produce business cycle fluctuations that looked like those observed in Canada, the United States, and emerging countries. Many of my research projects have focused on open-economy dimensions like movements in the trade balance, the current account, and the co-movement of economic fluctuations across countries.

Associate Chair, Associate Professor

My research is in International Trade and in Macroeconomics, where I explore theoretical, empirical, and quantitative questions. In my research in International Trade, I have studied the sources of the welfare gains from trade, the adequacy of current trade models to predict trade liberalization, and the changing patterns between rich and poor countries over the last two centuries. In my research in Macroeconomics, I have studied the fiscal policy nature of default episodes, the adequacy of modern macro models considering the labor share decline, and the sources of the Canadian economy’s productivity slowdown.
