Diversity and Economic Performance in a Model with Progressive Taxation
在一个动态一般均衡模型中，研究了消费者在劳动生产率和时间偏好上的差异如何通过劳动力构成和边际税率分布两个渠道影响长期经济绩效。
Abstract Is a more heterogeneous population beneficial or harmful to long-term economic performance? This article addresses this and other questions in a dynamic general equilibrium model where consumers differ in their labour productivity and time preference. We show how differences in the cross-sectional distribution of these characteristics can affect the economy via two channels. The first one involves changing the composition of the labour force; and the second one involves changing the cross-sectional distribution of the marginal tax rate. We show how these channels are, respectively, determined by the shape of the labour supply function and the curvature of the marginal tax function.
