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,...

Recent empirical studies have been searching for evidence on and driving forces for offshoring. Frequently, this has been done by analyzing gross trade flows related to offshore activities using gravity equations augmented by ad hoc measures of supply-side country differences. This paper...

We suggest that bilateral gravity equations augmented by ad hoc measures of absolute supply-side country differences are misspecified. Building on Haveman and Hummels (2004), we develop and test an alternative specification rooted in incomplete specialization that views bilateral gravity...

Motivated by growth models based on the variety of capital goods, recent empirical studies have established links between productivity and several trade-based measures of product variety, carrying the implication that these measures may represent technology. We study this implication by...
