A META-ANALYSIS OF TECHNICAL EFFICIENCY IN NIGERIAN AGRICULTURE
Provedor de dados: 31
Autores: Ogundari,   Kolawole.
This study sheds light on how study specific-characteristics impact mean technical efficiency (MTE) in Nigerian agriculture.  Also the paper extracts consensus message about MTE and its drivers in Nigerian agriculture based on studies covering the period 1999-2008. A meta-analysis using truncated regression was employed on a total of sixty four studies which yield eighty six observations for the econometric analysis. The regression results show that MTE in Nigerian agriculture increased significantly over the years. Study specific-characteristics such as sample size, number of inputs used as well as studies with focus on crop and livestock production were found to significantly impact MTE. Further analyses show that studies in the Northcentral, Southwest,...

Technical Efficiency and Adoption of Soil Conservation in El Salvador and Honduras
Provedor de dados: 31
Autores: Solis,   Daniel; Bravo-Ureta,   Boris E.; Quiroga,   Ricardo E.
A household-level switching regression model is implemented to examine potential selectivity bias for rural households under high and low levels of investments in soil conservation in El Salvador and Honduras. In the presence of selectivity bias, separate stochastic production frontiers are estimated for low and high adopters. The main results indicate that households with higher levels of investments in soil conservation show higher average TE than those with a lower level of investments. Constrains in the rural land and credit markets are likely explanations for these differences. The results also indicate that for farms with lower levels of investments in soil conservation access to credit is a significant factor explaining the sources of inefficiency....

Trip-Level Analysis of Efficiency Changes in Oregon's Deepwater Trawl Fishery
Provedor de dados: 31
Autores: Tomberlin,   David; Holloway,   Garth J.
In 2003, an industry-financed, government-administered buyback of trawl fishing permits and vessels took place on the US West Coast, resulting in the retirement of about one-third of the limited-entry trawl fleet. The lack of cost data in this fishery precludes an analysis of how the buyback has affected profitability, but changes in technical efficiency can provide some insight into the program's effects. This paper, the first of a planned series of analyses of the buyback's effect on technical efficiency in the trawl fleet, applies stochastic frontier analysis to assess whether technical efficiency changed perceptibly after 2003. We adopt a hierarchical modeling approach estimated with Markov Chain Monte Carlo methods, and present results from both...

The Role of Institutional Environments on Technical Efficiency: A Comparative Stochastic Frontier Analysis of Cotton Farmers in Benin, Burkina Faso, and Mali
Provedor de dados: 31
Autores: Theriault,   Veronique.
This paper examines the role of institutional environments on cotton farmer technical efficiency scores in Benin, Burkina Faso, and Mali using a stochastic frontier production approach. First, the key institutional changes that have occurred with the recent market-oriented reforms are discussed. Then, farm efficiency per country is measured using cross-sectional data collected by the Cotton Sector Reform Project of the Africa, Power, and Politics Programme in 2009. Results from a one-stage estimation procedure suggest that while no technical inefficiency exists in Benin, an average technical efficiency of 69% and 46% is found in Burkina Faso and Mali, respectively. Agricultural development policies focusing on reducing the inefficiency at the farm level in...

RECENT EVIDENCE ON AGRICULTURAL EFFICIENCY AND PRODUCTIVITY IN CHINA: A METAFRONTIER APPROACH
Provedor de dados: 31
Autores: Rungsuriyawiboon,   Supawat; Xiaobing,   Wang.
Economic reform in China helped transform the structure and volume of agricultural production and resulted in significant changes in efficiency and productivity. This paper measures agricultural technical efficiency (TE) and total factor productivity (TFP) in China by allowing producers operating under their own technologies. A metafrontier function approach is applied using a panel data set on 28 provinces during 1991-2005. The provinces are categorized into advanced- technology and low-technology provinces. Based on the metafrontier estimation, TFP growth is decomposed into TE change (TEC), technical change (TC) and scale efficiency change (SEC). This information is useful for policy makers to design suitable policies in enhancing agricultural TE and TFP...

Measurement and Sources of Technical Inefficiency in the Tunisian Citrus Growing Sector
Provedor de dados: 31
Autores: Dhehibi,   Boubaker; Lachaal,   Lassaad; Elloumi,   Mohamed; Messaoud,   Emna B.
This paper investigates farm level technical inefficiency of production and its determinants in a sample of 150 citrus producing farms in Tunisia using a stochastic frontier production function approach applied to cross section data. Results indicate that technical efficiency of production in the sample of citrus producing farms investigated ranges from a minimum of 26.84% to a maximum of 97.98% with an average technical efficiency estimate of 86.23%. This suggests that citrus producers may increase their production by as much as 13.77% through more efficient use of production inputs. Further, the estimated coefficients in the technical inefficiency model indicate the positive effect on technical efficiency of the share of productive trees, the...

O que significam as medidas de produtividade da agricultura?
Provedor de dados: 31
Autores: Alves,   Eliseu Roberto de Andrade.
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...

STOCHASTIC FRONTIER ANALYSIS OF NEW ZEALAND'S MANUFACTURING INDUSTRIES: SOME EMPIRICAL RESULTS
Provedor de dados: 31
Autores: Gounder,   Rukmani; Xayavong,   Vilaphonh.
This paper examines the sources of total factor productivity growth (TFP) in New Zealand's manufacturing industries over the period 1978-98 and over various sub-periods. Examination of the data adopts two stages using a stochastic frontier approach. The first stage involves the specification and estimation of the stochastic frontier production function and the prediction of technical efficiency effects. The second stage involves the specification of a regression model for the predicted technical efficiency effects. The sources of TFP growth have been decomposed into four components; i.e. technical progress, changes in technical efficiency, scale effects, and change in allocative efficiency. The empirical results show that productivity has been largely due...

What are the Key Constraints in Technical Efficiency of Smallholder Farmers in Africa? Empirical Evidence from Kenya
Provedor de dados: 31
Autores: Owuor,   George; Shem,   Ouma A.
The idea that smallholder farmers are reasonably efficient has triggered much debate in Sub-Saharan Africa. Indeed, efficiency of smallholder farmers has implications for choice of development strategy; reason being that Sub-Saharan countries derive over 60% of their livelihoods from smallholder agriculture and rural economic activities. This paper evaluates factors that promote production efficiency among smallholder farmers in Kenya as avenues for policy intervention. A production frontier function was fitted to a random sample derived from a survey carried in 2007. Results show that all conventional inputs had the expected significance. On the inefficiency indicators, ownership to farmland, attendance to agricultural workshops, access to credit and...

Scale Effects, Technical Efficiency and Land Lease in China
Provedor de dados: 31
Autores: Wang,   Xiaobing; Yu,   Xiaohua.
Using a panel dataset from Zhejiang province in China over the period 1995-2002, we propose a two-step estimation procedure to investigate the links between land lease activity and production efficiency. We find that the output elasticity with respect to land, the scale effect and the technical efficiency are higher for farmers involved in land-lease activities. In addition, technical efficiency and land-lease activity are endogenous, and farmers with higher technical efficiency are more likely to lease more land and adopt advanced technologies to achieve higher profits, which in turn alters the technical efficiency.

The Impact of Trade Openness on Technical Efficiency in U.S. Agriculture
Provedor de dados: 31
Autores: Miljkovic,   Dragan; Shaik,   Saleem.
This study addresses the impact of trade openness on technical efficiency in the U.S. agricultural sector.  The results indicate that trade protectionism illustrated with a decrease in the share of agricultural imports in agricultural GDP led to an increase in technical efficiency. A change in the share of agricultural exports in agricultural GDP had no impact on technical efficiency.  These results are partially consistent with the premise of the new trade theory, but also seem to be driven by the intricacies of the agricultural sector and agricultural policy in the US and internationally.

Technical efficiency of Organic Fertilizer in small farms of Nicaragua: 1998-2005
Provedor de dados: 31
Autores: Zúniga-González,   Carlos Alberto.
This article applies frontier production function analysis to small farms in Nicaragua during 1998-2005 (Battese and Coelli, 1988). The objective of this study is to estimate an average function that will provide a picture of the shape of the organic fertilizer technology of an average firm (in our case, agricultural production units). Furthermore I present a best-practice of organic fertilizer against which the efficiency of the firms within the primary sector can be measured (Coelli, T: 1995). The results show an average of technical efficiency acceptable which the makers of public policy in Nicaragua must considerer for the future. It is imperative if we consider an economy activity indexes that have increased during this period.
