摘要:This paper uses detailed micro data on service exports at the firm-destination-service level toanalyse the role of firm heterogeneity in shaping aggregate service exports in Belgium, France,Germany and Spain from 2003 to 2007. We decompose the level and the growth of aggregateservice exports into different trade margins paying special attention to firm heterogeneity withincountries. We find that the weak export growth of France is at least partly due to poorperformance by small exporters. By contrast, small exporters are the most dynamiccontributors to the aggregate exports of Belgium, Germany and Spain. Our results highlightthe importance of firm heterogeneity in understanding aggregate export growth.
