摘要
Using microdata of firm exports and international patent activity, we find that Greek innovative exporters, identified by their patent filing activity, have substantially higher export revenues by selling higher quantities rather than charging higher prices. To account for this evidence, we set up a horizontally differentiated product model in which an innovative exporter competes for market share in a destination against many non-innovative rivals. We argue that as the competition among the exporters of the non-innovative product becomes more intense, the innovative firm exports more compared with its non-innovative rivals in more distant markets, a prediction that is empirically confirmed in the dataset for Greek innovative exporters. Resume Innovation, brevets et commerce : analyse au niveau de l'entreprise. A l'aide de microdonnees d'entreprises relatives aux exportations et aux activites de brevetage international, nous montrons que les exportateurs grecs innovants, identifies par leurs depots de brevets, realisent des gains a l'exportation nettement superieurs en misant davantage sur les volumes de vente que sur l'augmentation des prix. Pour expliquer cette situation, nous avons elabore un modele de differenciation horizontale de produits dans lequel les exportateurs novateurs sont en competition avec de nombreux concurrents non innovants afin de gagner des parts de marche. Nous montrons qu'a mesure que la competition s'intensifie entre les exportateurs de produits non innovants, l'entreprise innovante exporte davantage que ses concurrents vers les marches plus eloignes ; cette prediction se verifie de fac,on empirique grace aux donnees relatives aux exportateurs grecs innovants.
