The Heckscher-Ohlin and Travis-Vanek theorems under uncertainty

The Heckscher-Ohlin theorem is valid under uncertainty of the special benchmark sort modelled by Helpman-Razin. Their pessimism over its validity is vanquished by more structure: rational expectations are imposed on consumers and identical and constant relative aversion to income risk is assumed. Under these circumstances, with free commodity trade, the Heckscher-Ohlin theorem holds for the international exchange of equities.
