In a two-country model, complete asset markets do not guarantee that individuals will choose to eliminate all (diversifiable) risk in aggregate consumption. The presence of nontraded goods forces individuals to choose between reducing uncertainty in aggregate consumption and in the composition between traded and nontraded goods. This choice depends on a comparison of the standard coefficient of relative risk aversion with a second type of risk aversion that becomes relevant when nontraded goods are present, one that captures aversion to risk in composition. Regardless of the decision made, asset trade always reduces the risk premium. Copyright 1994 by Blackwell Publishing Ltd.
