For decades the worldÂ’s agricultural markets have been highly distorted by national government policies, but very differently for different commodities such that a ranking of weighted average nominal rates of assistance across countries can be misleading as an indicator of the trade or welfare effects of policies affecting global markets. This article develops a new set of more-satisfactory indicators, drawing on the recent literature on trade restrictiveness indexes. It then estimates those two indicators for each of 28 key agricultural commodities from 1960 to 2004, based on a sample of 75 countries that together account for more than three-quarters of the worldÂ’s production of those agricultural commodities.
