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,...

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...
