A set of panel and spatial panel data models of employment and investment is estimated for 379 Polish counties over the 2003–2012 period using unique firm-level dataset for Polish special economic zones (SEZs). SEZs have strong positive impact on employment in the host county as well as in neighboring counties. The effects of SEZs on investment are weaker but nonetheless positive—investment in a given SEZ neither crowds out nor crowds in investments outside the SEZ. These findings are robust to changes in the estimation methods, the sample composition, the set of explanatory variables and the selection of a spatial weight matrix.
