This working paper summarizes the annualestimates, for each of the world's main high-incomecountries, of key distortion indicators defined in Andersonet al. (2008), and provides some summary statistics for thegroup's estimates. It begins with tables for thecountries of Western Europe, followed by Japan, the UnitedStates, Canada, Australia, and New Zealand. Shorter versionsfor subsets of countries are reproduced also as Appendixesin Anderson, Lattimore, Lloyd and MacLaren (2008), Gardner(2008), Honma and Hayami (2008), and Josling (2008). Fourtables are provided for each country: (a) the nominal rateof assistance to individual farm products covered in thestudy and their weighted average, using as weightsproduction valued at undistorted prices; (b) the relativerate of assistance to producers of agricultural (relative tonon-agricultural) tradable, again using as weightsproduction valued at undistorted prices, and the componentparts of the Relative Rate of Assistance (RRA) calculation;(c) the weights themselves for individual covered farmproducts and for the residual non-covered group of products,shown as percentages and so they sum to 100 percent; and (d)the trade status of each covered product each year. In thecase of the European Union (EU) countries of Western Europe,the trade status is assumed to be that of the EU membershipin any given year, since the Nominal Rate of Assistance(NRA) for each product is assumed to be the same for each EUmember (with the membership growing progressively frominitially 6 to 9 (from 1973), 12 (from 1986), and 15 (from1995). The average NRAs for all covered products differacross EU member countries though, because of theirdifferent weights for each product in their national valueof agricultural production.
