Are the most productive regions necessarily the most successful? Local effects of productivity growth on employment and earnings
研究美国县级层面生产率增长对就业、收入和工资增长的影响，发现生产率增长通常抑制就业增长，但提升工资和人均收入，且效果因地区而异。
Abstract Economists typically celebrate productivity growth as the chief way to improve living standards. Productivity growth may reduce costs, improve quality, or lead to innovation and new products, but if demand is insufficiently elastic, productivity growth can lead to weakening of labor markets. We study county‐level effects of productivity growth and productivity levels on growth in employment, income, and earnings. The results suggest that productivity growth generally suppresses job growth but has boosting effects on earnings and, to a lesser degree, on per‐capita income, although there is considerable variation across geographies and specific outcomes.
