A Representative Consumer Theory of Distribution
在单部门代表性消费者增长模型中引入消费者异质性，开发工具研究消费、资产和收入分布的演化，并应用于Ramsey-Cass-Koopmans和Arrow-Romer模型，展示分布动态和收入流动性的广泛可能性。
This paper introduces various sources of consumer heterogeneity in one-sector representative consumer (RC) growth models and develops tools to study the evolution of the distribution of consumptions, assets, and incomes. These tools are applied to the Ramsey-Cass-Koopmans model of optimal savings and the Arrow-Romer model of productive spillovers. The RC property per se places very few restrictions on the nature of observed distributions, and a wide range of distributive dynamics and income mobility patterns can arise as the equilibrium outcome. An example illustrates how to use these tools to generate quantitative predictions and compare them to the data.
