Putting industries into the Eaton–Kortum model

The article introduces the industry dimension into the Eaton-Kortum model of trade. Industries are linked with each other by domestic and international trade in intermediate goods. The model is parametrized using data for eight industries in 1989. It is used to perform several counterfactual simulations that are relevant to today's policy debates. First, the model is used to study the effects of the US--EU trade wars. It is found that trade wars have a greater negative effect on countries with large initial net export positions. It is also found that some trade war scenarios are more beneficial to the US while others to the EU. Second, the model is used to study the effects of trade barrier reductions between the high-income and middle-income countries. The results show that this trade liberalization tends to reinforce the pattern of trade according to technological comparative advantages. The results also show which industries should be targeted for barrier reductions depending on policy goals. The third set of simulations investigates spillovers from the technological growth in the US machinery industry. The results show how geography, technology, and industry links affect the propagation of this growth across countries and industries.
