This paper extends previous tests of the Heckscher-Ohlin-Vanek (H-O-V)
model by restricting testing to a group of countries expected to best
conform to the assumptions of the model. Specifically, this study res
tricts the sample to the G-7 countries which are similar in relative e
ndowments and technology. In this sample, limited empirical support fo
r H-O-V is found in the ''rank'' test of factors across countries and
the regressions. The results suggest that serious consideration of the
assumptions of the model may improve the concordance of the theory to
the data.
