Distribution of Agricultural NRAs across Countries and Products, 1955-84 and 1985-2007

The global database developed as an integral part of the World Bank's research project on Distortions to Agricultural Incentives, which is publicly available at www.worldbank.org/agdistortions, provides around 30,000 estimates of nominal rates of assistance to agricultural industries (NRAs) and associated consumer tax equivalents for 75 countries that together account for between 90 and 95 percent of the world’s population, farmers, agricultural output and total GDP. They also account for more than 85 percent of farm production and employment in each of Africa, Asia, Latin America and the transition economies of Europe and Central Asia as well as all OECD countries. More than 70 products are included (an average of 11 per country), which represents around 70 percent of the gross value of agricultural production in each of the focus countries, and just under two-thirds of global farm production valued at undistorted prices over the period covered. Not all countries had data for all of the entire 1955-2007 period, but the average number of years covered is 41 per country. This paper provides details of the coverage of the database. It also summarizes the distributions of the NRAs by showing two sets of Box plots for 1955-84 and 1985-2007, one set for various regions of the world, the other for all the covered products for each focus country.
