Growth, Trade, and Inequality
将企业和工人异质性引入内生增长模型，研究封闭与开放经济中增长与收入不平等的共同决定，以及一国政策对他国的溢出效应。
We introduce firm and worker heterogeneity into a model of innovation†driven endogenous growth. Individuals who differ in ability sort into either a research activity or a manufacturing sector. Research projects generate new varieties of a differentiated product. Projects differ in quality and the resulting technologies differ in productivity. In both sectors, there is a complementarity between firm quality and worker ability. We study the co†determination of growth and income inequality in both the closed and open economy, as well as the spillover effects of policy in one country to outcomes in others.
