Services, which are less traded than goods, rose from 58 percent of world expenditure in 1970 to 79 percent in 2015. In a trade model featuring nonhomothetic preferences and input-output linkages, we find that such structural change has restrained the growth in world trade to GDP by 16...

This paper assesses the quantitative importance of including sectoral heterogeneity in computing the gains from trade. Our framework draws from Caliendo and Parro (2015) and Alvarez and Lucas (2007) and has sectoral heterogeneity along five dimensions, including the elasticity of trade to trade...

Almost 80 percent of capital goods production in the world is concentrated in 10 countries. Poor countries import most of their capital goods. We argue that international trade in capital goods has quantitatively important effects on economic development through two channels: (i) capital...

In this paper we show that price equalization alone is not sufficient to establish that there are no barriers to international trade. There are many barrier combinations that deliver price equalization, but each combination implies a different volume of trade. Therefore, in order to make...

In this paper I quantitatively address the role of trade barriers in explaining why prices of services relative to tradables are positively correlated with levels of development across countries. I argue that trade barriers play a crucial role in shaping the cross-country pattern of...

International trade in capital goods has quantitatively important effects on economic development through two channels: capital formation and aggregate TFP. We embed a multi country, multi sector Ricardian model of trade into a neoclassical growth framework. Our model matches several trade and...

I quantitatively examine the effects of location-and sector-specific productivity growth on structural change across countries from 1970-2011. The results shed new light on the “hump shape" in industry's share in GDP across levels of development. There are two key features. First, otherwise...

The age distribution evolves asymmetrically across countries, influencing relative saving rates and labor supply. Emerging economies experienced faster increases in working age shares than advanced economies did. Using a dynamic, multicountry model I quantify the effect of demographic changes on...

We compute welfare gains from trade in a dynamic, multi-country Ricardian model where international trade affects capital accumulation. We calibrate the model for 93 countries and examine transition paths between steady-states after a permanent, uniform trade liberalization across countries. Our...
