Matching and Difference in Difference (DID) are two widespread methods that use pre-treatment outcomes to correct for … values. I find that Matching generally underestimates the average causal effect of the program and gets closer to the true … still performs better than Matching, especially in the middle of the life-cycle. These results are consistent with estimates …

This paper refers to an analysis of matching processes in occupational labour markets in terms of classes of jobs that … on the assumption of separate occupational labour markets. This assumption suggests that job search and matching … cross-sectional dependency lags for regressors to test the hypothesis that job search and matching occur across occupational …

This work refers to analyses of matching processes on occupational labour markets in Germany. Up to now, all studies in … "spatial" lags for regressors. The results show considerable dependencies between similar occupational groups in the matching …. This has important implications for estimating the matching efficiencies of unemployed and vacancies, because the matching …

Job mobility equilibrates disparities on local labor markets and influences the efficiency of the job matching process …. In this paper, we describe a job matching model that allows for simultaneous regional and occupational mobility … occupations in distinct regions. We specify a matching function for these local labor markets with regional spillovers …
