Export behavior and productivity growth: Evidence from Italian manufacturing firms

Export Behavior and Productivity Growth: Evidence from Italian Manufacturing Firms. — This paper provides econometric evidence supporting the hypothesis that exporting implies learning effects. Learning-by-exporting is modeled as a change, induced by export behavior, in the stochastic process governing firms’ productivity. Empirically, this is implemented by specifying cross-section regressions of labor productivity growth on measures of export behavior, controlling for past productivity growth and other firms’ characteristics. Using a sample of Italian manufacturing firms, it is found that exporters do not exhibit faster productivity growth. Nevertheless, growth in value added per worker has a positive and significant relation with firms’ export intensity. In other words, only firms substantially involved in exporting have a significantly higher rate of productivity growth. This result suggests that learning-by-exporting is by no means simply the outcome of the presence in the export market.
