Aggregate Productivity with Heterogeneous Agents

We develop a welfare-based measure of aggregate productivity for economies with heterogeneous households. For any change in the economic environment, we define the associated change in aggregate productivity as the largest shift in total factor-augmenting productivity that makes it feasible to leave

本文针对存在异质性家庭（heterogeneous households）的经济体，构建了一种基于福利的总生产率（aggregate productivity）测度方法。针对经济环境的任意变动，本文将与之对应的总生产率变动定义为可使得可行脱离得以实现的全要素增进型生产率（total factor-augmenting productivity）的最大变动幅度。
