Última UK Sugar Beet Farm Productivity Under Different Reform Scenarios: A Farm Level Analysis AgEcon Renwick, Alan W.; Revoredo-Giha, Cesar; Reader, Mark A.. 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/24665 Agricultural Productivity and Policies in Sub-Saharan Africa AgEcon Yu, Bingxin; Nin Pratt, Alejandro. We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 45 years, looking for evidence of recent changes in growth patterns using an improved nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan Africa’s agriculture between 1984 and 2006 after a long period of poor performance and decline. That recovery is the consequence of improved efficiency in production resulting from changes in the output structure and an adjustment in the use of inputs. Policy interventions, including fiscal, trade and sector specific policies, appear to have played an important role in improving agriculture’s performance. Despite the improved agricultural performance, SSA...

Ano: 2011 URL: http://purl.umn.edu/105400 Productivity in the New Zealand primary and downstream sectors AgEcon Cao, Kay; Forbes, Rod; Gardiner, Peter. In New Zealand, there has been increasing interest in productivity growth, both at economywide and sector levels. The Ministry of Agriculture and Forestry maintains a total factor productivity series for the primary sectors. As part of the ministry’'s flagship project on growth and productivity, we are reviewing the methodology and extending productivity derivation to downstream industries. This paper presents our research results to date.

Ano: 2007 URL: http://purl.umn.edu/10356 Food Safety Regulation and Firm Productivity: Evidence from the French Food Industry AgEcon Requillart, Vincent; Nauges, Celine; Simioni, Michel; Bontemps, Christophe. The purpose of this article is to assess whether food safety regulations imposed by the European Union in the 2000s may have induced a slow-down in the productivity of firms in the food processing sector. The impact of regulations on costs and productivity has seldom been studied. This article contributes to the literature by measuring productivity change using a panel of French food processing firms for the years 1996 to 2006. To do so, we develop an original iterative testing procedure based on the comparison of the distribution of efficiency scores of a set of firms. Our results confirm that productivity decreased in the poultry processing industry at the time when safety regulation was reinforced.

Ano: 2012 URL: http://purl.umn.edu/124378 Land Quality in an International Comparison: It's Importance in Measuring Productivity AgEcon Nehring, Richard F.; Ball, V. Eldon; Breneman, Vincent E.. The purpose of this paper has been to present quality-adjusted values for land in the United States and nine European countries using price and quantity data for 1990. Disregarding such differences in the quality-adjusted land input would generate biased estimates of the land input and thus of total factor productivity. Land quality adjustments could potentially be enhanced further with additional data on soil characteristics, climate, and other productivity-related characteristics.

Ano: 2002 URL: http://purl.umn.edu/24910 Getting Implicit Shadow Prices Right for the Estimation of the Malmquist Index: The Case of Agricultural Total Factor Productivity in Developing Countries AgEcon Nin Pratt, Alejandro; Yu, Bingxin. The Malmquist index has become extensively used in international comparisons of agricultural productivity since it does not require prices for its estimation, which are normally not available. However, the DEA approach used to estimate this index still uses implicit price information. This entails potential problems because these methods are susceptible to the effect of data noise, and shadow prices can prove to be inconsistent with prior knowledge on cost shares. In this paper we analyze implicit input shadow shares used in the DEA approach to estimate agricultural productivity using the Malmquist index for 72 developing countries. We then set bounds to the implicit input shares introducing information on their likely value and compare constrained and...

Ano: 2009 URL: http://purl.umn.edu/51797 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...

Ano: 2007 URL: http://purl.umn.edu/118322 The Changing Economics of U.S. Hog Production AgEcon Key, Nigel D.; McBride, William D.. The increasing size and specialization of hog operations reflect structural change in U.S. swine production during the past 15 years. The number of farms with hogs has declined by over 70 percent, as hog enterprises have grown larger. Large operations that specialize in a single phase of production have replaced farrow-to-finish operations that performed all phases of production. The use of production contracts has increased. Operations producing under contract are larger than independent operations and are more likely to specialize in a single phase of production. These structural changes have coincided with substantial gains in efficiency for hog farms and lower production costs. Most of these productivity gains are attributable to increases in the scale...

Ano: 2007 URL: http://purl.umn.edu/6389 Public investment in R&D and extension and productivity in Australian broadacre agriculture AgEcon Sheng, Yu; Gray, Emily M.; Mullen, John D.. 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,...

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 and by employing the random coefficient frontier approach, decompose productivity growth into its technical efficiency and technical progress components. Efforts were 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...

Ano: 2004 URL: http://purl.umn.edu/23691 A Reappraisal of the Role of Agriculture in Economic Growth in Melanesian Countries AgEcon Fleming, Euan M.; Fleming, Pauline. Fortunes in the agricultural sectors of four of the largest South Pacific countries are traced in recent decades by estimating the single factoral terms of trade index. The single factoral terms of trade are measured for agriculture in four Melanesian countries-Fiji, Papua New Guinea, Solomon Islands and Vanuatu-over the period, 1970 to 2002. This index provides a useful method to assess changes in returns to factors employed in agricultural production in these countries. Except in Solomon Islands, farmers experienced a deteriorating index, indicating that they have reaped progressively lower returns to their resources. In Solomon Islands, returns to resources are shown to have increased slightly. A sustained contribution by the agricultural sector to...

Ano: 2006 URL: http://purl.umn.edu/25715 Productivity and Efficiency of Corporate and Individual Farms in Ukraine AgEcon Lerman, Zvi; Sedik, David J.. The paper presents a comparative analysis of the productivity of corporate and individual farms in Ukraine based primarily on cross-section data from a farm survey conducted by FAO in 2005. We calculate partial land and labor productivity, total factor productivity, and technical efficiency scores (using Stochastic Frontier Analysis) for farms of different organizational forms. Our results demonstrate with considerable confidence that, contrary to established convictions among the Ukrainian decision makers, the large corporate farms are not more productive than the smaller family farms. This finding is not restricted to Ukraine, as a similar result has been obtained by in Moldova, Russia, and the U.S. Policies encouraging a shift from large corporate farms...

Ano: 2012 URL: http://purl.umn.edu/123334 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.

Ano: 2007 URL: http://purl.umn.edu/6388 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 Productivity Change in the Australian Sheep Industry Revisited AgEcon Villano, Renato A.; Fleming, Euan M.; Farrell, Terence C.; Fleming, Pauline. Recent low estimates of total factor productivity change for wool producers in the Australian sheep industry indicate that they are struggling to improve their performance. This evidence is at odds with the views of many technical observers of industry performance, prompting us to re-estimate total factor productivity change for farmers in a benchmarking group in south-west Victoria who had been the subject of such a negative finding. An important transformation in sheep production in Australia in recent decades has been a change in enterprise mix, notably a greater presence of prime lamb production. This change complicates the process of computing efficiency and productivity change. We demonstrate that a multi-input multi-output approach, based on the use...

Limited data on the allocation of inputs to different activities has limited agricultural economists' attempts to measure sub-sector productivity growth in agriculture. However, recent developments have enabled us to estimate total factor productivity (TFP) growth for crops and livestock accounting for input-output allocation. This paper extends previous work on TFP measurement for livestock into ruminants and non-ruminant productivity measurement, given the differences in productivity growth rates among these species. The results show that the non-ruminant sector is more dynamic than the ruminant sector, driving most of the productivity growth within the livestock sector. Given the rapid rates of productivity growth observed recently, non-ruminant...

Ano: 2005 URL: http://purl.umn.edu/19395 The Rapid Rise of China's Dairy Sector: Factors Behind the Growth in Demand and Supply AgEcon Fuller, Frank H.; Huang, Jikun; Ma, Hengyun; Rozelle, Scott. With the rapid growth in China's dairy industry, a number of recent papers have addressed either the supply or the demand trends for dairy products in China. None, however, presents a systematic explanation for the recent growth in both the supply and demand for dairy products. The goal of this paper is to sketch a more comprehensive picture of China's dairy sector and to assess the nature of the sector's development in the coming decades. Drawing upon several empirical studies, we examine the trends in dairy product consumption to create a composite picture of the factors underlying the recent growth. We also empirically investigate the sources of production gains in milk supply and assess the relative importance of expanding herd size, changes in the...
