Does labor market polarization push large and small cities apart?
Core argument: In France's large cities between 1994 and 2015, middle-wage jobs declined sharply and were replaced two-to-one by high-paid positions, while low-paid jobs grew modestly.
Between 1994 and 2015, large cities in France experienced significant labor market polarization, characterized by a sharp decline in middle-wage jobs, which were replaced two-to-one with high-paid positions. This shift resulted in a dramatic change in the employment landscape of large cities, where high-skill jobs expanded greatly, while low-paid jobs saw modest growth. Conversely, smaller cities faced a different pattern, with a more moderated loss of middle-wage jobs primarily replaced by low-paid positions, leading to a divergence between large and small cities. The data from 117 French cities confirm that labor market polarization is nearly ubiquitous, with 115 cities exhibiting this trend. The study highlights the importance of understanding the heterogeneity within middle-wage jobs and the implications for economic policy, as large cities continue to attract high-skill employment while smaller cities struggle with job quality and wage disparities.



















Ed Comment:Add how the pandemic broke the valley’s hold on tech jobs. I think this will accelerate something I fear—the offshoring of tech jobs abroad, especially the most technical jobs. That’s going to lead to the more entrepreneurialism abroad or the most valuable kind. The more our tech giants can zoom in the talent and breakthrough, the less they will care about US working. There will be tech hubs in every country attracting their best talent.
