Countries that trade more with each other tend to have more correlated business cycles. Yet, traditional international business cycle models predict a much weaker link between trade and business cycle comovement. We propose that the international diffusion of technology through trade in...

Growth and imports are correlated across countries, but the mechanisms underlying this relationship are not well understood. I develop a multi-country model in which imports and growth are connected by technological innovations and their international diffusion through trade. Fitting the model...

In this paper, we establish the importance of experience in international trade in reducing unmeasured trade costs and facilitating bilateral trade. We find a strong role for experience, measured in years of positive trade, for both aggregate and sectoral bilateral trade. In an augmented gravity...

We compute welfare gains from trade in a dynamic, multicountry model with capital accumulation. We examine transition paths for 93 countries following a permanent, uniform, unanticipated trade liberalization. Both the relative price of investment and the investment rate respond to changes in...

I develop a multicountry-model in which economic growth is driven mainly by domestic innovation and the adoption of foreign technologies embodied in traded intermediate goods. Fitting the model to data on innovation, output per capita, and trade in varieties for the period 1996-2007, I estimate...

This paper studies the role of international trade of essential goods during a pandemic. We consider a multi-country multi-sector model with essential and non-essential goods. Essential goods provide utility relative to a reference consumption level, and a pandemic consists of an increase in...

Growth and imports are correlated across countries, but the mechanisms underlying this relationship are not well understood. I develop a multi-country model in which imports and growth are endogenous variables connected by technological innovations and their international diffusion through...
