On Gravity,Specialization and Intra-industry Trade
AbstractThis paper derives the necessary and sufficient condition for the simple gravity equation to hold: the market share of an exporting country is constant across all importing countries. Specialization is just one example satisfying this condition. It holds in a variety of situations where multiple producers compete with a homogeneous good.Further, this paper shows that the ratio of bilateral trade to the product of partner incomes is increasing in the extent of specialization and in the intensity of intra-industry trade. Since the relationship is not model-specific, the correlations among these variables do not support any specific model.
