Accelerated Productivity Growth Offsets Decline in Resource Expansion in Global Agriculture AgEcon
Fuglie, Keith O..
Rapid increases in agricultural commodity prices during 2006-08 raised concerns that agricultural productivity growth may not be keeping up with increasing demand for agricultural commodities. ERS has developed a new index of total factor productivity (TFP) in global agriculture to provide a more comprehensive understanding of longrun sources of agricultural output growth. ERS research shows that the average rate of growth in global agricultural TFP has accelerated in recent decades and accounts for an increasing share of growth in agricultural production. Faster TFP growth has offset declining growth in agricultural land, labor, and other resources, although TFP growth across countries and global regions remains unevenly distributed.

Adoption of Agricultural Production Practices: Lessons Learned from the U.S. Department of Agriculture Area Studies Project AgEcon
Caswell, Margriet; Fuglie, Keith O.; Ingram, Cassandra; Jans, Sharon; Kascak, Catherine.
The U.S. Department of Agriculture Area Studies Project was designed to characterize the extent of adoption of nutrient, pest, soil, and water management practices and to assess the factors that affect adoption for a wide range of management strategies across different natural resource regions. The project entailed the administration of a detailed field-level survey to farmers in 12 watersheds in the Nation to gather data on agricultural practices, input use, and natural resource characteristics associated with farming activities. The data were analyzed by the Economic Research Service using a consistent methodological approach with the full set of data to study the constraints associated with the adoption of micronutrients, N-testing, split nitrogen...

Brazil's Rising Agricultural Productivity and World Competitiveness AgEcon
Rada, Nicholas E.; Buccola, Steven T.; Fuglie, Keith O..
Brazil now is the largest coffee, sugar, and fruit juice producer, second-largest soybean and beef producer, and third-largest corn and broiler producer. It has overtaken the U.S. in poultry exports, nearly matches the U.S. in soybean exports, and dominates global trade in frozen orange juice. To test and better understand these advances, we draw on decennial farm censuses to examine technical change and efficiency in Brazilian agriculture. Our approach is to estimate a stochastic, multi-product, output distance frontier, using a translog functional form and data disaggregated to the micro-region (sub-state) level. Using two consecutive decennial farm censuses, we combine state-level Fisher productivity-change indexes with state-level translog distance...

CONSERVATION TILLAGE AND PESTICIDE USE IN THE CORNBELT AgEcon
Fuglie, Keith O..
Adoption of conservation tillage can lead to substantial environmental benefits from reduced soil erosion. But benefits may be partially offset if adoption increases reliance on agricultural chemicals. Using area study data from the Cornbelt, this study examines factors affecting adoption of no-till and other conservation tillage systems and their effect on chemical use and corn yield. The results find no evidence that herbicide or fertilizer application rates are higher on fields with conservation tillage systems compared with conventional tillage. However, insecticide use may increase somewhat and yield may be lower. Current demographic trends in U.S. agriculture favor continued diffusion of conservation tillage.

ECONOMIC INCENTIVES AND RESOURCE ALLOCATION IN U.S. PUBLIC AND PRIVATE PLANT BREEDING AgEcon
Fuglie, Keith O.; Walker, Thomas S..
Private investment in plant breeding has been increasing while public plant breeding has stagnated or declined. Moreover, research investment among crop commodities is uneven. Using a comprehensive survey of U.S. plant breeders from 1994, we use a simultaneous equations model to examine incentives and public-private tradeoffs in plant breeding research among 84 crop commodities. Allocation of private breeders among crops is strongly influenced by market size, hybrid seed technology, and ease of breeding improvement. In general, the allocation of public breeders does not appear to "crowd out" private breeders, but some competition may occur in applied breeding. Public breeding declines as private breeding increases on a commodity. Public breeding is...

Economic Returns to Public Agricultural Research AgEcon
Fuglie, Keith O.; Heisey, Paul W..
Over the last several decades, the U.S. agricultural sector has sustained impressive productivity growth. The Nation's agricultural research system, including Federal-State public research as well as private-sector research, has been a key driver of this growth. Economic analysis finds strong and consistent evidence that investment in agricultural research has yielded high returns per dollar spent. These returns include benefits not only to the farm sector but also to the food industry and consumers in the form of more abundant commodities at lower prices.

PRIVATE INVESTMENT IN AGRICULTURAL RESEARCH AND INTERNATIONAL TECHNOLOGY TRANSFER IN ASIA AgEcon
Pray, Carl E.; Fuglie, Keith O..
This study addresses the questions of future sources of technology for increasing food and agricultural production by considering the situation in Asia. This region of the world is particularly appropriate for studying these questions because of the dynamic changes in population and incomes. How much private research is there and what is it producing? Will the private sector compensate for declining public agricultural research investments in Asia? What can governments do to stimulate private research and protect farmers from harmful or defective technology? Agribusiness firm's R&D investments were evaluated in selected developing countries during 1996 and 1998 and compared with data from a similar study conducted in the mid-1980s. The largest amount...

Productivity Growth in Indonesian Agriculture, 1961-2000 AgEcon
Fuglie, Keith O..
We use an index number approach to measure total factor productivity (TFP) growth in Indonesian crop and livestock agriculture between 1961-2000. A Tornqvist index is developed to minimize biases that may result from relative price changes in factor and output weights. The results indicate that agricultural TFP growth accelerated in the 1970s but was halted in the late 1990s. Agricultural productivity growth was not limited to rice but also extended to other food and horticultural crops.

Productivity Growth in U.S. Agriculture AgEcon
Fuglie, Keith O.; MacDonald, James C.; Ball, V. Eldon.
Innovation and changes in technology have been a driving force for gains in productivity growth in U.S. agriculture. USDA's Economic Research Service has developed annual indexes of agricultural inputs, outputs, and total factor productivity (TFP) for 1948 through 2004. American agriculture relies almost entirely on productivity growth to raise output. By lowering the cost of agricultural commodities, productivity growth benefits not only farmers but also food manufacturers and consumers.

Research Investments and Market Structure in the Food Processing, Agricultural Input, and Biofuel Industries Worldwide AgEcon
Fuglie, Keith O.; Heisey, Paul W.; King, John L.; Day-Rubenstein, Kelly A.; Schimmelpfennig, David E.; Wang, Sun Ling.
Meeting growing global demand for food, fiber, and biofuel requires robust investment in agricultural research and development (R&D) from both public and private sectors. This study examines global R&D spending by private industry in seven agricultural input sectors, food manufacturing, and biofuel and describes the changing structure of these industries. In 2007 (the latest year for which comprehensive estimates are available), the private sector spent $19.7 billion on food and agricultural research (56 percent in food manufacturing and 44 percent in agricultural input sectors) and accounted for about half of total public and private spending on food and agricultural R&D in high-income countries. In R&D related to biofuel, annual...

RESOURCE ALLOCATION IN JOINT PUBLIC-PRIVATE AGRICULTURAL RESEARCH AgEcon
Day-Rubenstein, Kelly A.; Fuglie, Keith O..
Federal technology transfer legislation has encouraged increased collaboration between the public and private sectors, including joint research ventures known as Cooperative Research and Development Agreements (CRADAs). While several economically important technologies have been developed through CRADAs, there is concern that CRADA may divert public research from its central research missions. This study compares the pattern of research resource allocation for CRADA projects at the U.S. Department of Agriculture with research priorities of public and private intramural agricultural research. The findings suggest that CRADAs have attracted considerable private co-financing of joint research projects, and may have enabled public research to concentrate...

Technology Capital: The Price of Admission to the Growth Club AgEcon
Evenson, Robert E.; Fuglie, Keith O..
We assess long-run patterns of global agricultural productivity growth in developing countries between 1970 and 2005 and examine the relationship between investments in technology capital and productivity. To measure agricultural total factor productivity (TFP) we employ a Solow-type growth accounting method to decompose output growth into input and TFP growth. For technology capital we construct two indexes reflecting national capacities in agricultural research and education-extension for 87 developing countries. We then correlate technology capital levels with long-term growth rates in agricultural TFP. Our findings show that average agricultural TFP growth in developing countries accelerated in the 1980s and 1990s but fell marginally in the early...

Uncovering Productivity Growth in the Disaggregate: Indonesia's Dueling Agricultural Sub-Sectors AgEcon
Rada, Nicholas E.; Buccola, Steven T.; Fuglie, Keith O..
The success of seed-fertilizer technologies and government subsidies in attaining nearly self-sufficient rice production in the mid-1980s encouraged the Indonesian government soon afterward to shift resources away from food crops and toward export-oriented crops. These shifts were reinforced by trade liberalization and a sharp devaluation of the rupiah after the 1997 Asian financial crisis, which exerted Indonesia’s comparative advantage in tropical perennial products. In the present paper, we ask whether such events have altered Indonesia’s agricultural growth strategy from a food-crop to an export-crop one. With an innovative multi-output stochastic distance frontier model and provincial production and policy-related data from 1985 to 2005, we...

"Vent-For- Surplus" as a Source of Agricultural Growth in Northeast Thailand, 1950-1986 AgEcon
Fuglie, Keith O..
This paper reviews the "vent-for-surplus" model of agricultural development, in which access to foreign markets allows "surplus productive capacity" to be exploited. The "indirect effects" of trade contribute to long-term economic growth even after the direct gains from trade are realized. How the new income streams are distributed amongst the population may also carry implications for long-term growth prospects. The model is used to explain the rapid expansion in export crop production that has taken place in the Northeast Region of Thailand over the past twenty-five years. It is shown that the growth in export production was achieved at very little expense to the subsistence sector by employing previously underutilized land and labor resources. Growth...
