We present direct evidence of the importance of matching in wage determination. It is based on an empirical specification that estimates the returns to person-, firm-, and match-specific determinants of match productivity. We call these person, firm, and match effects. The distinction between...

We consider the problem of estimating and decomposing wage differentials in the presence of unobserved worker, firm, and match heterogeneity. Controlling for these unobservables corrects omitted variable bias in previous studies. It also allows us to measure the contribution of unmeasured...

One approach to limiting disclosure risk in public-use microdata is to release multiply-imputed, partially synthetic data sets. These are data on actual respondents, but with confidential data replaced by multiply-imputed synthetic values. A mis-specified imputation model can invalidate...
