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,...

This meta-analysis summarizes and explains the variation in the deterring effect of distance on tourism flows by analyzing 870 estimates from 139 primary studies utilizing data covering the last 25 years. We find substantial heterogeneity among studies that mostly correlates with (unobserved)...

This paper studies the effect of institutions on trade flows, using a gravity model approach. We start from a standard gravity equation that incorporates geographical proximity, language, trade policy and common history. These factors reflect the costs of trade across geographical and cultural...

To serve foreign markets, firms can either export or set up a local subsidiary through horizontal Foreign Direct Investment (FDI). The conventional proximity-concentration theory suggests that FDI substitutes for trade if distance between countries is large, while exports become more important...
