Abstract

Existing estimates of the public/private wage gap allow for possible sorting of individuals into one sector, but they rely on parametric assumptions that may introduce substantial bias in the parameter of interest. Solutions are semi- and nonparametric approaches. For Italy, the latter methods yield a gap of approximately 20%, whereas the bias from parametric assumptions is as large as 10%.
