In a two-cone Heckscher–Ohlin model with CES preferences and a continuum of goods, new northern goods increase the northern skill premium if they are skilled-labor intensive, and may increase the premium if they are unskilled-labor intensive. Thus, the introduction of new goods into US technology could have done more to increase the US skill premium than a closed-economy model would predict. I ...

This article recapitulates some of the trade theories reputed to be twentieth century. Here, Heckscher-Ohlin theory (with its variants), endogenous growth theory, product cycle and new were considered. review thereof, amidst others, highlight assumptions these thus present critique same theories.

In the paper we introduce technological comparative advantage and transaction costs into the Heckscher-Olin (HO) model and refine the HO theorem, the Stolper-Samuelson theorem, the Rybczynski theorem, and factor equalization theorem. The refined core theorems can be used to accommodate recent empirical evidence that is at odds with the core theorems.

Previous empirical tests have found that,contrary to the conclusions of the HeckscherOhlin model, the factor composition of traded goods fails to reveal relative factor abundance rankings. Using a nonparametric approach, this paper discusses the refutability of two of the assumptions of the HO model: that countries have identical homothetic preferences and identical constant returns to scale pr...
