Evolution of the Labor Market in a Regional City: The Changing Economic Performance of Emigrants from Mexico City*
利用墨西哥城移民的收入轨迹数据，研究区域城市莱昂的劳动力市场演变，发现早期和近期移民的收入增长斜率不同，后期趋于收敛，为区域劳动力市场理论提供了微观基础。
Abstract. This paper draws on micro-level data to fully inform the debate on decentralization and regional development. Using labor-income trajectories of emigrants from Mexico City, the paper analyzes how the labor market in a regional city, Leon, evolves. Results from the econometric model suggest that migrants’ labor-income trajectories differ between the large agglomeration and the regional city in an early stage of the evolution of the labor market, but converge in a later stage. Specifically, the slope of the earning function for recent migrants is steeper and statistically different from the slope for early migrants. The findings presented in this paper enrich the existing theory by providing microfoundations to a typically macroeconomic area of research and enable policy makers to better understand the processes underpinning the evolution of regional labor markets.
