Within a higher-dimensional incomplete specialization Heckscher-Ohlin framework, we first develop a gravity model that views bilateral gravity equations as statistical relationships constrained on countries’ multilateral specialization patterns. Second, we test our model empirically by using a...

By combining and extending the previous literature, we develop and test a gravity specification that views bilateral gravity equations rooted in a Heckscher-Ohlin framework as statistical relationships constrained on countries’ multilateral specialization patterns. According to our results,...
