The Strong-Factor-Intensity Hypothesis: A Multisectoral Test
TLDR
In this article, the authors provide an empirical test of the strong-factor-intensity hypothesis among U.S. Census regions, based on a test based on regional, rather than international, data.Abstract:
T HE so-called strong-factor-intensity hypothesis is a crucial element in both the Heckscher-Ohlin theory of comparative advantage and the ancillary factor-price-equalization theorem which was deduced by Heckscher (1919) and developed fully by Samuelson (1948, 1949). In view of its central role in these two theories, it is important to have some notion of the empirical content of the hypothesis. Accordingly, this paper provides an empirical test of the hypothesis among U.S. Census regions. It seems that a test based upon regional, rather than international,' data is preferable on at least two grounds (see Sec. III).read more

A survey of trade and wage inequality: anomalies, resolutions and new trends
TL;DR: The authors surveys recent studies on trade and wage inequality and links new trends in inequality, such as job polarization and within-group inequality, to the trade and inequality literature, and concludes that the effect of trade, though relatively small compared to that of technological change, is more significant than generally believed.

Is a skill intensity reversal a mere theoretical curiosum? Evidence from the U.S. and Mexico
TL;DR: In this article, the authors show clear-cut evidence for the existence of a skill intensity reversal in the HeckscherOhlin model, and they also show that a rising skill premium in two countries can be explained by the heckscher-ohlin model assuming a "skill intensity reversal."
