We specify a many-nation, many-commodity model of international trade invol
ving tariff and quota distortions. We derive conditions for the existence o
f strict Pareto improving multilateral reforms of quotas, and obtain recomm
endations for specific directions of such quota reforms. Given a mild rank
condition on the world trade matrix, all directions of quota reform that at
tain a strict Pareto improvement using international lump sum compensation
remain strict Pareto improving even without lump sum compensation, provided
that the quota reform is accompanied by a multilateral reform of tariffs.
The precise nature of the tariff reform that accomplishes the redistributio
n task is determined. (C) 1000 Elsevier Science B.V. All rights reserved.
