Despite a gradual and sustained decline in the contribution of agriculture to the economies of the member countries of the Organization for Economic Cooperation and Development (OECD), the sector remains socially and politically important. Although agriculture accounts for less than 2% of the gross domestic product of the OECD countries, it occupies over 35% of their total land area. Predominantly rural regions, where agriculture remains particularly important, contain almost one quarter of the population of OECD countries. The past quarter century has witnessed signi?cant changes in agricultural po- cies in OECD countries. Although total support remains high, a shift has taken place from price-linked measures to direct income support, most notably in the European Union. Policies have been adapted to meet pressing social concerns, such as ens- ing food security and improving environmental quality. OECD countries face major economic issues due to the ageing of their populations and the need to adapt to gl- alization and increasing competition from emerging economies. Continued pressure to reform agricultural policies will be exerted by the need to economize on the use of scarce public resources. At the same time, agriculture faces new challenges g- erated by climate change, the "greening" of the economy, increasing scarcity of energy and water, and the demands placed on the food system by an expanding world population.

Agricultural Productivity: Measurement and Sources of Growth addresses measurement issues and techniques in agricultural productivity analysis, applying those techniques to recently published data sets for American agriculture. The data sets are used to estimate and explain state level productivity and efficiency differences, and to test different approaches to productivity measurement. The rise in agricultural productivity is the single most important source of economic growth in the U.S. farm sector, and the rate of productivity growth is estimated to be higher in agriculture than in the non-farm sector. It is important to understand productivity sources and to measure its growth properly, including the effects of environmental externalities.

Both the methods and the data can be accessed by economists at the state level to conduct analyses for their own states. In a sense, although not explicitly, the book provides a guide to using the productivity data available on the website of the U.S. Department of Agriculture/Economic Research Service. It should be of interest to a broad spectrum of professionals in academia, the government, and the private sector.
