This paper empirically examines the heterogeneity in the effects of multiple dimensions of distance on trade across detailed product groups. Using finite mixture modelling on bilateral trade data at the 3-digit SITC level, we endogenously group product categories into an, a priori unknown, number of segments based on estimated coefficients of multiple dimensions of distance in the gravity equation. The paper contributes to the literature by offering a new classification of products into homogeneous groups. We find that distance decay functions in a gravity model of international trade at a disaggregate level reveal a complex process that involve location characteristics (comparative and natural advantages, demand patterns or preferences) as well as intrinsic sensitivity of trade to multiple dimensions of distance. Keywords: bilateral trade, gravity models, cultural distance, institutions, product heterogeneity, finite mixture modelling JEL code: F14, F21, F23
