Fiscal Policy, Specialization, and Trade in the Two-Sector Model: The Return of Ricardo?
构建了一个包含内生资本积累和跨期最优的两部门新古典国际贸易模型，发现政府支出政策难以改变既有的专业化与贸易格局，但税收政策变化可能导致世界生产格局的剧烈重组。
This paper develops a two-sector neoclassical model of international trade with endogenous capital accumulation and intertemporal optimization. In contrast to the traditional "2 x 2" model, there is a Ricardian implication that countries specialize according to comparative advantage. Consequently, the theory predicts that government expenditure policies are unlikely to affect the established pattern of specialization and trade, but that changes in tax policies can result in a dramatic reorganization of world production. Further, the dynamic 2 x 2 x 2 model can explain many of the salient features of international trade that are problematic for the standard Heckscher-Ohlin-Samuelson model.
