Asian Americans faced a disproportionately larger surge in unemployment rates than other racial and ethnic groups during the Covid-19 pandemic. While existing literature typically examines labor demand channels to explain this, we instead explore a labor supply channel. Our hypothesis is that...

We study the importance of international trade in structural change. Our framework has both productivity and trade cost shocks, and allows for non-unitary income and substitution elasticities. We calibrate our model to investigate South Korea's structural change between 1971 and 2005. We find...

This paper investigates both aggregate and distributional impacts of the trade integration of China, India, and Central and Eastern Europe in a quantitative multi-country multi-sector model, comparing outcomes with and without factor market frictions. Under perfect within-country factor...

This paper evaluates the global welfare impact of China's trade integration and technological change in a quantitative Ricardian-Heckscher-Ohlin model implemented on 75 countries. We simulate two alternative productivity growth scenarios: a "balanced" one in which China's productivity grows at...

What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore cross-country spillovers of tax...

We estimate productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, comparative advantage has become weaker: productivity grew systematically faster in sectors that were initially...

We develop a quantitative framework to assess the cross-state implications of a U.S. trade policy change: a unilateral increase in the import tariff from 2% to 25% across all goods-producing sectors. Although the U.S. gains overall from the tariff increase, we find the impact differs starkly...

Covid-19 became a global health emergency when it threatened the catastrophic collapse of health systems as demand for health goods and services and their relative prices surged. Governments responded with lockdowns and increases in transfers. Empirical evidence shows that lockdowns and...

In this paper we empirically explore the relationship between debt and output in a panel of 72 countries over the period 1970–2014 using a vector autoregression (VAR). We document two puzzling empirical findings that contrast with what is predicted by a standard small open economy model by...

Empirically, net capital inflows are pro-cyclical in developed countries and counter-cyclical in developing countries. That said, private inflows are pro-cyclical and public in flows are counter-cyclical in both groups of countries. The dominance of private (public) in flows in developed...
