Última Has growth in productivity in Australian broadacre agriculture slowed? AgEcon Sheng, Yu; Mullen, John D.; Zhao, Shiji. Agricultural productivity growth has been strong relative to other sectors in the Australian economy, and relative to the agricultural sectors of other developed countries. However, as commonly observed among other developed economies, growth in productivity in the broadacre sector of Australian agriculture seems to have slowed in the past decade. This paper uses the adjusted cumulative sum square (CUSQ) index to examine the trend stability of total factor productivity in Australian broadacre agriculture over the period 1952-53 to 2006-07. The results show that a significant slowdown occurred around the mid-1990s. Further analysis shows that the slowdown in productivity growth is driven by a longterm decline in public R&D investment in addition to poor...

Ano: 2010 URL: http://purl.umn.edu/59266 The contribution of innovations in total factor productivity of organic olive enterprises AgEcon Karafillis, C.C.; Papanagiotou, Evangelos. This paper measures the contribution of innovations in total factor productivity(TFP) of organic olive farmers. By constructing an innovation variable instead of the use of a time trend, technical change is replaced by technical difference and TFP growth becomes TFP difference. Primary cross section data on organic olive enterprises from a Greek region is used in the application of the restricted frontier profit function. Farmers are classified into groups according to their innovative ‘profile’. TFP difference among consecutive innovation groups is decomposed into technical difference and adjustment in innovativeness effects. Furthermore, efficiency differences among innovation groups are estimated. Results indicate that more innovative farmers perform...

Ano: 2008 URL: http://purl.umn.edu/43645 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.

Ano: 2003 URL: http://purl.umn.edu/57868 Public investment in agricultural research and development in Australia remains a sensible policy option AgEcon Mullen, John D.. There is evidence that productivity in Australia’s broadacre agriculture (extensive cropping and livestock industries) has been slowing in the past decade. A series of poor seasons has been partly responsible, but an econometric analysis of structural changes in the trend of total factor productivity (TFP) indicates that stagnant public investment in agricultural R&D has also made a significant contribution to this slowdown in TFP. Related econometric analysis of the returns to public investment in agricultural R&D in the broadacre sector confirms that the rate of return to investment remains high. Despite these findings, a recent enquiry by Australia’s Productivity Commission into the financing of rural research suggests that the public sector may...

Ano: 2012 URL: http://purl.umn.edu/122896 Livestock in China: Commodity specific total factor productivity decomposition using new panel data AgEcon Rae, Allan N.; Ma, Hengyun; Huang, Jikun; Rozelle, Scott. Studies of total factor productivity in livestock production are rare, but when available provide useful information especially in the context of developing countries such as China where livestock is becoming more important in the domestic agricultural economy. We estimate total factor productivity (TFP) for four major livestock products in China employing the stochastic frontier approach, and decompose productivity growth into its technical efficiency and technical progress components. Efforts are made to adjust and augment the available livestock statistics. The results show that growth in TFP and its components varied between the 1980s and the 1990s as well as over production structures. While there is evidence of considerable technical innovation in...

Ano: 2005 URL: http://purl.umn.edu/19527 What is the appropriate level of aggregation for productivity indices? Comparing district, regional and national measures AgEcon Conradie, Beatrice; Piesse, Jenifer; Thirtle, Colin G.. This paper examines the appropriate level of aggregation for the construction of total factor productivity (TFP) indices. The dataset covers the magisterial districts and statistical regions of the Western Cape for the years 1952 to 2002. Over these five decades agricultural production in the Western Cape grew twice as fast as in the country as a whole but this average masks substantial regional variation. Results show that TFP growth was negative in the Karoo, moderate in the Swartland, Overberg and Southern Cape, and generally above 2% per year in the Boland and Breede River Valleys, where there is extensive irrigation.

Ano: 2009 URL: http://purl.umn.edu/49162 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.

The purpose of this paper is to study the effect that the imminent reform in the European Union (EU) sugar regime may have on farm productivity in the United Kingdom (UK). We perform the analysis on a sample of sugar beet farms representative of all the UK sugar beet regions. To estimate the changes in productivity, we estimate a multi-output cost function representing the cropping part of the farm, which is the component that would be mostly affected by the sugar beet reform. We use this cost function to compute the new allocation of outputs and inputs after the changes in the sugar beet quota and price support. This are subsequently used to compute measures of total factor productivity. Our results show slight decreases in the productivity at the...

Ano: 2005 URL: http://purl.umn.edu/31936 Is the Share of Agricultural Maintenance Research Rising? AgEcon Sparger, John Adam; Heisey, Paul W.; Alwang, Jeffrey Roger; Norton, George W.. This study measures the amount of agricultural research engaged in maintenance research for commodities and non-commodities. The percentage of commodity based maintenance research has risen from roughly 35% in 1986 to 41% in 2008. The percentage of non-commodity based agricultural research is roughly 29%. Additionally, an empirical model is developed to explain maintenance research expenditures. The influences of agricultural research funding, climatic conditions, pest and pathogen control, and agricultural production on maintenance research expenditures are tested in the long and short run. Each category has a statistically significant impact on maintenance research expenditures.

Ano: 2010 URL: http://purl.umn.edu/61302 CONVERGENCE IN U.S. TFP GROWTH FOR AGRICULTURE: IMPLICATIONS OF INTERSTATE RESEARCH SPILLOVERS FOR FUNDING AGRICULTURAL RESEARCH AgEcon McCunn, Alan; Huffman, Wallace E.. This paper examines state agricultural total factor productivity (TFP) data, 1950-1982, for evidence of convergence, i.e., TFP growth rates of the future are inversely related to the TFP level at the starting data. After finding evidence of convergence, the paper examines the contributions of public and private R&D to convergence and presents implications for a more efficient organization of public agricultural research. For example, we find that increasing a states own investment in public agricultural research reduces the rate of TFP convergence but larger public investments in surrounding areas that potentially spillin increase the rate of convergence. Also, the results imply that the average rate of convergence in our best fitting model is about...

Ano: 1998 URL: http://purl.umn.edu/18266 CAP Reforms and Total Factor Productivity Growth in Belgian Agriculture: A Malmquist Index Approach AgEcon Coelli, Tim J.; Perelman, Sergio; Van Lierde, Dirk. Have the 1992 and 2000 CAP reforms had any discernable effect upon agricultural productivity? In this study we derive detailed information on the total factor productivity (TFP) growth of arable farms in Belgium over a 16-year period from 1987 to 2002. Calculations are based on a carefully constructed high-quality detailed farm-level data set containing 1728 observations, involving over 100 farms in most years. Three output variables (cereals, other crops, other outputs) and four input variables (land, labour, capital and other inputs) are constructed, using multilateral Fisher index numbers where crop aggregation is required. The TFP measures are calculated using a Malmquist TFP index relative to a series of data envelopment analysis (DEA) frontiers....

Ano: 2005 URL: http://purl.umn.edu/24665 Has Green Revolution Bypassed Coarse Cereals? The Indian Experience AgEcon Janaiah, Aldas; Achoth, Lalith; Bantilan, Ma Cynthia S.. This paper analysed the growth performance of non-rice crop sectors by estimating total factor productivity (TFP) growth for the selected coarse cereals viz., maize, sorghum and pearl millet in India. The analysis indicates that the TFP growth contributed substantially to the output growth of coarse cereals over the past three decades. The TFP growth was higher in those states where coverage of irrigation was relatively high. TFP grew at an average of 1.4 percent per annum through out the Green Revolution (GR) period for sorghum in the sate of Maharashtra where about half of the India’s sorghum area is concentrated mostly under rainfed conditions. Although small in absolute terms over the past three decades, the overall findings suggest that GR...

Ano: 2005 URL: http://purl.umn.edu/110142 Valuing State-Level Funding for Research: Results for Florida AgEcon Moss, Charles B.. This study analyzes the value of agricultural research to Florida by examining the effect of research spending on agricultural productivity, as measured by a total factor productivity index, and profitability, as measured by net farm income. Results suggest that research expenditures do increase agricultural productivity in the state. However, agricultural productivity does not affect net cash income. Further, the economic rents to the productivity gains do not accrue to land values. Instead, the economic value of research innovations accrues more to consumers than to producers. Thus, consumers are the ultimate beneficiaries of agricultural research in Florida, thereby justifying public funding for agricultural research.

Ano: 2006 URL: http://purl.umn.edu/43757 Productivity Growth, Technical Efficiency and Technical Change on Minnesota Farms AgEcon Olson, Kent D.; Vu, Linh. Changes and trends in farm productivity have been of intense interest to many involved with agriculture. This study used data envelopment analysis (DEA) to estimate the output-oriented Malmquist total factor productivity (TFP) index from panel data for 1993-2006 for farms in Southern Minnesota. Bootstrap methods were used to estimate confidence intervals for the productivity, efficiency change and technical change indices. The model included three inputs (labor, land and immediate expenditures) and six outputs (corn, soybean, milk, hog, beef, and nonfarm income). Productivity growth was found to be positive during the period, with an average annual productivity growth of 6.6 percent. However, TFP growth has been slowing down in recent years and indeed...

An understanding of the efficiency with which women farmers are operating, particularly where they account for the largest share of the labor force required for agricultural production, is essential for designing appropriate policies to improve the overall performance of agriculture as well as the livelihood of women farmers. This paper contributes to the gender productivity debate by drawing on crop production data collected in three districts (Ada, Akaki and Gimbichu) in East Shoa, Ethiopia during the 1999/2000 cropping season through detailed multi-visit surveys of 80 farm households of which 39 were female-headed households. Using the Tornqvist-Theil index, Total factor productivity (TFP) is measured to analyze crop production efficiency differentials...

Ano: 2004 URL: http://purl.umn.edu/23691 Use of the single factoral terms of trade to analyse agricultural production AgEcon Fleming, Euan M.. The aim in this note is to reintroduce the single factoral terms of trade into the policy arena. This economic concept has scarcely been used by analysts or policy makers over the past three decades. It is defined and compared favourably with other terms of trade concepts in terms of their usefulness to agricultural policy makers in Australia. A distinction is made between the single factoral terms of trade from the viewpoint of the farm business and from the viewpoint of the farm household, but only slightly different indices are specified in each case because of the very high positive correlation between farm prices paid and consumer prices. Developing industry-level indices appears to be a more attractive way to proceed given the substantially different...

This paper uses time-series data to examine the relationship between public research and development (R&D) and extension investment and productivity growth in Australian broadacre agriculture. The results show that public R&D investment has significantly promoted productivity growth in Australia’s broadacre sector over the past five decades (1953 to 2007). Moreover, the relative contributions of domestic and foreign R&D have been roughly equal, accounting for an estimated 0.6 per cent and 0.63 per cent of annual total factor productivity (TFP) growth in the broadacre sector, respectively. The elasticity of TFP to knowledge stocks of research (both domestic and foreign) and extension were estimated to be around 0.20–0.24 and 0.07–0.15,...
