We will show that in our model the informational barrier acts like a tax on trade that is zero up to a certain trade volume, then increasing with volume. Full efficiency is therefore achieved between countries whose labor-producer endowment ratios are similar enough, because even with random matching there are enough good matches to transfer sufficient labor demand to equalize wages. If the two countries’ endowment ratios are different enough, however, sufficient labor demand to equalize wages cannot be transferred unless some bad matches are accepted, but such matches are only acceptable in the presence of gains from trade created by an equilibrium wage differential.

The more different are the labor-producer endowment ratios, the worse is the marginal match and the greater this equilibrium wage differential must be. When wages are not equalized, the comparative statics of the model have the property that an increase in one country’s labor endowment decreases both its wage and that of its trading partner, but decreases its own wage more. We can call this property “excess sensitivity” from the point of view of the country whose endowment has changed and “partial insulation” from the point of view of its trading partner.

We then enrich our model by including group ties. Group ties extend complete information to the international market: each group member knows the types of all other group members in both countries. This facilitates the transfer of labor demand and increases the extent to which factor endowment ratios can differ without ruling out achievement of full efficiency. In this respect group ties act like an improvement in the matching technology between countries. Group ties differ from such an improvement, however, in that they only overcome informational barriers within the group. When full efficiency is not achieved we can therefore expect the ties to have distributional effects, and in fact we find that they may cause aggregate profits of producers who are not members of the group to fall even though world wages and world profits as a whole increase.

Moreover, although ties must reinforce the allocative effect of prices in a two-country model, this need not be true if there is more than one international market so that ties do not necessarily link the countries with the largest difference in factor endowment ratios. We thus conclude the paper with the demonstration that in a three-countiy model ties can have an effect analogous to harmful “trade diversion,” thereby reducing world income. It is the limitations of prices and ties that may place us in the world of the second best: prices convey incomplete information to the complete set of producers while ties convey complete information to an incomplete set of producers.
