This paper reassesses the wage curve applying regional price deflators, whereas in the literature only uniform national price levels are generally used in wage curve regressions. Existing estimates for the unemployment elasticities vary across countries but lie mostly in the neighborhood of −0.1. Using the data for the 49 US states over the 2008–2015 period and 16 Polish NUTS2 regions over the 2000–2015 period, we test the impact of regional prices on the wage curve employing a variety of approaches. We confirm the existence of wage curves for both countries. Following the theory of monopsonistic competition, this inverse relationship stems from the costs faced by both firms and workers. However, the elasticity of local unemployment and spatial spillovers decreases significantly if regional price deflators are applied. This is due to the fact that there exists a negative relationship between regional prices and unemployment.

本文使用区域价格平减指数重新评估工资曲线，而在文献中，工资曲线回归通常只使用统一的国家价格水平。失业弹性的现有估计因国家而异，但大多在 -0.1 附近。使用 2008-2015 年期间美国 49 个州和 2000-2015 年期间 16 个波兰 NUTS2 地区的数据，我们使用各种方法测试区域价格对工资曲线的影响。我们确认了两国工资曲线的存在。根据垄断竞争理论，这种反向关系源于企业和工人面临的成本。然而，如果应用区域价格平减指数，当地失业和空间溢出的弹性将显着降低。
