Abstract | ||
We use comparable micro level panel data for 14 countries and a set of
identically specified empirical models to investigate the relationship
between exports and productivity. Our overall results are in line with
the big picture that is by now familiar from the literature: Exporters
are more productive than non-exporters when observed and unobserved
heterogeneity are controlled for, and these exporter productivity
premia tend to increase with the share of exports in total sales;
there is strong evidence in favour of self-selection of more
productive firms into export markets, but nearly no evidence in favour
of the learning-by-exporting hypothesis. We document that the exporter
premia differ considerably across countries in identically specified
empirical models. In a meta-analysis of our results we find that
countries that are more open and have more effective government report
higher productivity premia. However, the level of development per se
does not appear to be an explanation for the observed cross-country
differences.
