标题：The Case of the Missing Trade and Other Mysteries作者：DANIEL TREFLER *

简介：The Heckscher-Ohlin-Vanek (HOV) theorem, which predicts that countries will
export products that are made from factors in great supply, performs poorly.
However, deviations from HOV follow pronounced patterns. Trade is missing
relative to its HOV prediction. Also, rich countries appear scarce in most factors
and poor countries appear abundant in all factors, a fact that squares poorly
with the HOV prediction that abundant factors are exported. As suggested by the
patterns, HOV is rejected empirically in favor of a modification that allows
for home bias in consumption and international technology differences. (JEL
