一般均衡中的工作阶梯与财富动态

Job Ladder and Wealth Dynamics in General Equilibrium
Econometrica · 2026 · Leo Kaas、Étienne Lalé、Nawid Siassi

中文摘要

本文构建了一个宏观经济模型,将不完全市场的世代交叠经济与工作阶梯相结合,该工作阶梯具有序贯工资议价、就业与非就业劳动者内生的搜寻努力以及匹配质量的差异。借助这些要素,我们的模型为总量生产的三个主要投入——资本、就业和劳动效率——提供了统一的微观基础。校准后的模型能够很好地拟合搜寻活动、求职成功率、工资和储蓄的经验年龄剖面。我们运用该模型,通过资本、就业和劳动效率渠道分析税收与转移支付政策对劳动力市场动态和总体经济活动的影响。降低失业保险金和降低累进性的税制会给新生劳动者带来福利损失,这主要由更高的消费风险和更昂贵的搜寻努力所驱动;这两项政策在年龄、收入和财富维度上具有差异化效应。

Abstract

This paper develops a macroeconomic model that combines an incomplete‐markets overlapping‐generations economy with a job ladder featuring sequential wage bargaining, endogenous search effort of employed and non‐employed workers, and differences in match quality. With these ingredients, our model provides a joint microfoundation for the three main inputs in aggregate production: capital, employment, and labor efficiency. The calibrated model offers a good fit to the empirical age profiles of search activity, job‐finding rates, wages, and savings. We use the model to analyze the impact of tax and transfer policies for labor market dynamics and aggregate economic activity via capital, employment, and labor efficiency channels. Lower unemployment benefits and a less progressive tax schedule bring about welfare losses for a newborn worker which are mainly driven by higher consumption risk and costlier search effort; both policies have differential effects along the age, income, and wealth dimensions.
