We study the theoretical properties and counterfactual predictions of a large class of general equilibrium trade and economic geography models. By combining aggregate factor supply and demand functions with market-clearing conditions, we prove that existence, uniqueness, and-given observed trade flows-the counterfactual predictions of any model within this class depend only on the demand and supply elasticities ("gravity constants"). Using a new "model-implied" instrumental variables approach, we estimate these gravity constants and use these estimates to compute the impact of a trade war between the United States and China.
