This paper provides detailed empirical evidence on the scope of mismatch in Germany in the past decade, using a comprehensive administrative data set that allows for disaggregation at the levels of industry, occupation and region. The findings suggest that regional mismatch did not play an important role in explaining movements of aggregate unemployment. Across industries and occupations, there was a decrease in mismatch unemployment from over 5 percent to below 4 percent (on the highest disaggregation level), whereas the share of mismatch unemployment (across industries and occupations) within total unemployment remains almost unchanged between 2000 and 2010. Concluding, mismatch unemployment fell but the Hartz reforms did not reduce mismatch overproportionally compared with search frictions, in line with the fact that reallocation across occupations appears not to have been eased.
