We evaluate the impact of large minimum wage hikes on employment and wage growth in Poland between 2004 and 2018. We estimate panel data models utilizing the considerable variation in wage levels, and in minimum wage bites, across 73 Polish NUTS 3 regions. We find that minimum wage hikes had a significant positive effect on wage growth and a significant negative effect on employment growth only in regions of Poland that were in the first tercile of the regional wage distribution in 2007. These effects were moderate in size, and appear to be more relevant for wages. Specifically, if the ratio of minimum wage to average wage had remained constant after 2007, by 2018, the average wages in these regions would have been 3.2% lower, while employment would have been 1.2% higher. In the remaining two-thirds of Polish regions, we find no significant effects of minimum wage hikes on average wages or on employment.

波兰最低工资的异质区域效应

我们评估了 2004 年至 2018 年间大幅提高最低工资对波兰就业和工资增长的影响。我们利用波兰 73 个 NUTS 3 地区工资水平和最低工资的巨大差异来估计面板数据模型。我们发现，仅在 2007 年处于区域工资分布的前三分之一的波兰地区，最低工资上涨对工资增长产生了显着的积极影响，而对就业增长产生了显着的负面影响。这些影响的规模适中，并且似乎与工资更相关。具体而言，如果最低工资与平均工资的比率在 2007 年之后保持不变，那么到 2018 年，这些地区的平均工资将下降 3.2%，而就业率将上升 1.2%。在其余三分之二的波兰地区，
