The purpose of this study is to analyse the regional diversification of the impact of post-accession emigration from Poland on the Polish labour market with particular focus on the wage formation process. The analysis is performed on the Polish LFS data from 2004 to 2011 and employes the measure of the elasticity of wages with respect to emigration. Results show significant differences in the wage adjustment processes to new labor market conditions caused by emigration from different regions. Differences were identified between groups of regions characterised by different scales of emigration, population densities, dominant types of residence, unemployment rates, and economic situations. A 10 percent decline in the labour supply due to emigration increases wages by about 1,5-6,5 percent, depending on the assumptions made.
