Services, which are less traded than goods, rose from 58 percent of world expenditure in 1970 to 79 percent in 2015. Using a Ricardian trade model incorporating endogenous structural change, we quantify how this substantial shift in consumption has affected trade. Without structural change, we...

Motivated by increasing trade and fragmentation of production across countries since World War II, we build a dynamic two-country model featuring sequential, multistage production and capital accumulation. As trade costs decline over time, globalvalue-chain (GVC) trade expands across countries,...

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

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...

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...

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...

We add to recent evidence on deindustrialization and document a new pattern: increasing industry polarization over time. We assess whether these new features of structural change can be explained by a dynamic open economy model with two primary driving forces, sector-biased productivity growth...

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 develop a structural framework to identify the sources of cross-state heterogeneity in response to US tariff changes. We quantify the effects of unilaterally increasing US tariffs by 25 percentage points across sectors. Welfare changes range from −0.8 percent in Oregon to 2.1 percent in...

Europe's debt crisis casts doubt on the effectiveness of fiscal austerity in highly-integrated economies. Closed-economy models overestimate its effectiveness, because they underestimate tax-base elasticities and ignore cross-country tax externalities. In contrast, we study tax responses to debt...
