It is well known that the law of comparative advantage breaks down when applied to individual commodities or pairs of commodities in a many-commodity world. This paper shows that the law is nonetheless valid if restated in terms of averages across all commodities. Specifically, a theorem and several corollaries are derived which establish correlations between vectors of trade and vectors containing relative-autarky-price measures of comparative advantage. These results are proven in a general many-commodity model that allows for tariffs, transport costs, and other impediments to trade.

The subject is retiming of lags in a system of linear difference equations. The issues are (i) the effect of retiming on stability and (ii) the effect of retiming on speed of adjustment. Regarding (i), a theorem due to Bear [1] is sharpened; and new conditions for stability to survive under a retiming of lags are obtained. Regarding (ii), the main results concern the effects of lag perturbations and spread perturbations on speed of adjustment in models with nonnegative coefficients.
