We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selection into trade, while accommodating asymmetries in trade flows.  A new equation for the proportion of exporting firms takes a gravity form: the extensive margin is also affected by...

Do better international logistics reduce trade costs, raising a developing country's exports? Yes, but the magnitude of the effect depends on the country's size. The authors apply a gravity model that accounts for firm heterogeneity and multilateral resistance to a comprehensive new...

Drawing on a new and comprehensive measure of logistics quality, our gravity model suggests logistics in the exporting and partner-country can have an important impact on bilateral exports.  A one standard deviation improvement in the exporter's logistics quality, which for example would...
