Measuring the dispersion of productivity or efficiency across firms in a market or industry is rife with methodological issues. Nevertheless, the existence of considerable dispersion now is well documented and widely accepted. Less well understood are the economic features and mechanisms...

This paper uses cross-country micro-aggregated data on firm dynamics and productivity from the ECB CompNet database to provide empirical evidence on factor reallocation in the European Union (EU). The analysis finds that reallocation is towards more productive firms although the magnitude varies...

This paper uses cross-country micro-aggregated data on rm dynamics and productivity from the ECB CompNet database to provide empirical evidence on factor reallocation in the EU. The analysis finds that reallocation is towards more productive firms although the magnitude varies across countries...

Applications tend to ignore that measured TFP reflects the variation of output that cannot be explained by changes in inputs. Such a change is not necessarily technological, so measured TFP differences across firms are an amalgam of technological, efficiency and other differences in attributes,...
