The overlap problem is crucial in propensity score matching. Recently, Crump et al. (2009) showed that trimming provides a simple and robust solution to the overlap problem. In this study, we use a simulation approach to show that trimming is inferior to the caliper mechanism. We show that in...

This paper approaches the question of efficiency in job placement using regional data for Polish regions (policy-relevant NUTS 4 level) over the time span of 2000-2008. Using a unique data set we estimate the matching function using stochastic frontier as well as difference-in-difference...

We study empirically the impact of social indicators on growth in the context of FDI and trade. In this article, we argue that the positive growth effects of FDI and trade arise from factors such as knowledge spillovers or technological upgrading. Therefore, the effect of FDI and trade depends...
