搜寻摩擦下降、失业与自雇

Declining Search Frictions, Unemployment and Self-Employment
The Economic Journal · 2024 · Piotr Denderski、Florian Sniekers

中文摘要

在多数OECD国家,失业率没有呈现趋势性变化;若信息与通信技术的进步降低了劳动力市场摩擦,这一现象便令人费解。我们从解析和定量两方面表明,考虑自雇率的长期下降即可解开这一谜题。尽管劳动力市场摩擦下降在理论上能够解释这些趋势,我们却提供了相反的因果证据:宽带互联网的推广提高了自雇率并降低了失业率。我们用一个同时包含劳动力市场与商品市场摩擦的新模型来调和这些观察。我们通过劳动力市场摩擦相对于商品市场摩擦下降得更多,在定量上解释了自雇率下降与失业率无趋势这两点。

Abstract

Abstract In most OECD countries, unemployment rates show no trend, which is puzzling if advancements in information and communication technologies decrease labour-market frictions. We show, both analytically and quantitatively, that accounting for the secular decline in self-employment rates solves the puzzle. While declining labour-market frictions can theoretically explain these trends, we provide contradictory causal evidence that the roll-out of broadband internet has increased self-employment and decreased unemployment rates. We reconcile these observations with a new model featuring frictions in both labour and goods markets. We explain falling self-employment and non-trending unemployment quantitatively by labour-market frictions declining relatively more than goods-market frictions.
