Technology, Geography, and Trade
构建了一个融入真实地理特征的李嘉图贸易一般均衡模型，利用1990年19个OECD国家的双边贸易、价格和地理数据估计参数，并探讨了贸易收益、新技术扩散和关税削减的影响。
We develop a Ricardian trade model that incorporates realistic geographic features into general equilibrium. It delivers simple structural equations for bilateral trade with parameters relating to absolute advantage, to comparative advantage (promoting trade), and to geographic barriers (resisting it). We estimate the parameters with data on bilateral trade in manufactures, prices, and geography from 19 OECD countries in 1990. We use the model to explore various issues such as the gains from trade, the role of trade in spreading the benefits of new technology, and the effects of tariff reduction.
