This paper analyzes efficiency and total factor productivity (TFP) change of large agricultural enterprises during their transition to a market economy in Ukraine. In this case the efficiency is calculated by data envelopment analysis and the productivity change is measured by the Malmquist Productivity Change Index in the period between 1990 and 1999. On average, TFP declined by 6% annually, dropping a total 42%. The main reason for the observed TFP decline is a decrease in technical efficiency, which is found to be remarkably significant. At the same time there is a high variation among individual enterprises: their distribution of efficiency scores widens, which indicates that the farms diverge with respect to their economic performance. The Tobit...

The UK post-farm gate food chain comprises manufacturing, wholesaling , retailing and catering. Current turnover is around £250 billion per annum. Total factor productivity measures the ratio of inputs to outputs. However, most studies have only included the marketable inputs and outputs within the system. Following criticisms of the negative effects of the food chain this paper adopts a n index based approach to measuring Total Social Factor Productivity, which includes the major externalities within the food chain. Generally, whilst TFP growth rates are low over the period 1998-2002, these have reduced even further when negative externalities are included.

DOES GROUP AFFILIATION INCREASE PRODUCTIVITY AND EFFICIENCY IN RUSSIA’S AGRICULTURE? EVIDENCE FROM AGROHOLDINGS IN THE BELGOROD OBLAST

Kunimitsu, Yoji.

This study analyzed causative factors on TFP growth in Japanese agriculture. The regression analysis with consideration of correlation between factors demonstrated that without further deregulation for introducing new comers, enlarging farm management area and asset management for keeping public capital, agricultural TFP cannot be improved in the future.

The impact of group affiliation to agroholdings on enterprise performance in terms of productivity and efficiency is controversially discussed in the literature. However, only few papers evaluate the effects of group membership on the productivity and the efficiency of agricultural enterprises in Russia. The underlying research question of this paper is therefore whether farms that belong to agroholdings perform better than independent farms. We calculate partial land and labor productivity, total factor productivity and technical efficiency scores for the two categories of independent farms and members of agroholdings. In this paper a production function approach is estimated in the framework of stochastic frontier analysis. The results are used to...

In order to measure agriculture sustainability, the efficient use of inputs becomes a crucial issue. In this perspective, the analysts concentrate their attention on the total factor productivity index (TFP). In this view, Lynam and Herdt (1989) proposed the TFP as a suitable assessment of the sustainability of single crops, of cropping systems or of farming systems. Even if the TFP does not take into account the non-market output (social and environmental aspects), it is possible to argue that a negative trend of TFP represents a resources’ degradation if related to the generated outputs. On the other hand, the non-negative trend of TFP represents a fitting measure of a sustainable agricultural system and of an efficient use of the resources. The aim of...

The primary objective of this study is to empirically determine whether North American Free Trade Agreement (NAFTA) has contributed to increased agricultural productivity in any of its member countries. Implementation of the NAFTA began on January 1, 1994. This agreement removed most barriers to trade and investment among the United States, Canada, and Mexico, in which all non-tariff barriers to agricultural trade between these countries were eliminated. Data Envelopment Analysis (DEA) and the Malmquist Productivity Index were used to estimate the total factor productivity change, technical change, and efficiency change of agricultural production for each NAFTA country. Then, using time series data, the efficiency changes in countries were compared to...

Recent policy interest has been directed at the sustainability of food industries, in particular the post-farm gate food chain. This comprises of manufacturing, wholesaling, retailing and catering. In order to measure sustainability Byerlee and Murgai (2001) have argued that productivity measures, alongside key indicators of resource quality trends, should be used to indicate sustainable growth. This paper adopts this approach by presenting Fisher indexes of both Total Factor Productivity (TFP) index and for prominent externalities emerging from the food chain over the period 1998 to 2002. TFP shows an average annual growth rate of –0.52% per annum. Input growth, in particular intermediate purchases, has outstripped output growth over the entirety of this...

Some productivity measures area analyzed. The emphasis is on concepts, limitations and on some empirical results. Software is not discussed. The productivity measures are classified in optimized, whenever obtained by an optimization procedure, and not optimized, as yield, labor productivity and total factor productivity (ptf). The work shows when yields and total factor productivity say the same thing to conclude that this is possible only in a primitive agriculture where labor and land are the only factors of production used. This type of agriculture is present only in backward regions of Brazil. Hence yield, except in this situation, is a poor measure of profitability. Empirical works show that the development of Brazilian agriculture follows a path of...

ORGANIC FARMING IN DENMARK-PRODUCTIVITY, TECHNICAL CHANGE AND MARKET EXIT

Sauer, Johannes; Park, Timothy A.; Graversen, Jesper T..

This paper attempts to quantitatively measure the change in the productivity of Danish organic farming in recent years. Based on a translog production frontier framework the technical and scale efficiency on farm level is analysed by following a time trends as well as a general index model specification. We further try to analyse the significance of subsidies for promoting long term growth in organic production by estimating a bootstrapped bivariate probit model with respect to factors influencing the probability of organic market exit. The results revealed significant differencies in the organic farms' technical efficiencies, no significant total factor productivity growth and even a slightly negative rate of...

Resumen: El objetivo de este trabajo es medir el cambio de la productividad en la agricultura chilena durante el período 1961-96. La Productividad Total de los Factores (PTF) fue calculada mediante índices Törnqvist. Los datos utilizados para estimar estos índices incluyen precios y cantidades de 51 cultivos, de la mano de obra, de la tierra, del capital y de factores intermedios. El análisis revela que mientras los productos crecieron un 2,69% anual, el uso de factores de producción bajó un 0,09%; por lo tanto, la PTF creció a una tasa promedio anual del 2,78% entre 1961 y 1996. Se realizó además un análisis para siete períodos correspondientes a diferentes regímenes políticos. La PTF creció a un promedio anual de 1,83% con Alessandri (1961-64), 3,12%...

The Geography and Channels of Diffusion at the World's Technology Frontier

Keller, Wolfgang.

Convergence in per capita income turns on whether technological knowledge spillovers are global or local. Global spillovers favor convergence, while a geographically limited scope of knowledge diffusion can lead to regional clusters of countries with persistently different levels of income per capita. This paper estimates the importance of geographic distance for technology diffusion, how this changed over time, and whether international trade, foreign direct investment, and communication flows serve as important channels of diffusion. The analysis is based on examining the productivity effects of R&D expenditures in the world's seven major industrialized countries between 1970 and 1995. First, I find that the scope of technology diffusion is severely...

Total factor productivity growth (TFPG) has been traditionally associated with technological change. We show that when a factor of production, such as energy, generates an environmental externality in the form of CO2 emissions which is not internalized because of lack of environmental policy, then TFPG estimates could be biased. This is because the contribution of environment as a factor of production is not accounted for in the growth accounting framework. Empirical estimates confirm this hypothesis and suggest that part of what is regarded as technology’s contribution to growth could be attributed to the use of environment in output production.
