A Gravity Model for Components of Imports


  • Kandogan, Yener


This paper develops a gravity model to explain different components of imports. It is shown that specific variables from competing trade theories affect each component differently: As economic sizes or relative factor endowments become similar, the volume of intra-industry imports, especially that of its horizontal component increases. Furthermore, the typical variables of an extended gravity model have different impact on each component: Colonial relations are important determinants of inter-industry imports whereas cultural proximity based on religion and language plays a more crucial role in determining intra-industry imports. Overall, the significance of these different effects suggests that the proposed decomposition of imports into its components removes a widespread but unnecessary restriction in the gravity models.
