Travail de recherche/Working paper
| Résumé : | This paper studies the implications of imperfect competition in firm-to-firm trade. Using a dataset on all transactions between Belgian firms, we find that firms charge higher markups if they have higher input shares among their buyers. We build a model where firms charge different markups to buyers depending on the input shares they have in each buyer. The estimated model suggests large distortions due to double marginalization: Reducing all markups in firm-to-firm also highlight the importance of accounting for endogeneities in firm-to-firm markups in predicting the effects of shock transmissions. |
