We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...

Goods trade and international mobility of labor are typically analyzed separately. While there is excellent research in both fields, far less is known about the interrelationships between international migration and international trade. This paper provides a first structurally estimable model of...

Quantifying the welfare effects of trade liberalization is a core issue in international trade. Existing frameworks assume perfect labor markets and therefore ignore the effects of aggregate employment changes for welfare. We develop a quantitative trade framework which explicitly models labor...

The future international climate policy architecture will most likely consist of partial climate policy initiatives like the EU's Emission Trading System. Trade integration threatens to undermine these systems' environmental effectiveness by shifting emissions to other countries. We estimate a...

Krugman's (1979, 1980) monoplistic competition model of trade showed that countries with more similar per-capita GDP trade more with each other. Does this mean that developing countries shift trade towards developed countries as a result of high economic growth? The results reported in this...

We offer a new explanation as to why international trade is so volatile in response to economic shocks. Our approach combines the uncertainty shock idea of Bloom (2009) with a model of trade, extending the idea to the open economy. Firms import intermediate inputs from home or foreign suppliers,...

Earlier work established the notion that international terrorism harms international trade. This evidence was based on annual data with responses in the same year as attacks and incidents and on empirical models which ignored general equilibrium effects. We provide evidence that, if at all,...
