Competitividad y cadena de valor de cítricos en México: Caso Nuevo León.
Provedor de dados: Depósito Institucional Abierto de Documentos Digitales del Colegio de Postgraduados (COLPOS DIGITAL )
Autores: Magdaleno Hernández, Adalberto.
Lo cítricos de Nuevo León,  tienen calidad de exportación, pero existe una barrera sanitaria que impide su libre comercio a EUA.  El gobierno estatal esta realizando inversiones para que parte de su región citrícola sea declarada libre de mosca de la fruta, eliminando así dicha barrera comercial. Sin embargo, hay pocos estudios que indiquen: la rentabilidad, ventaja comparativa de la producción citrícola, el desarrollo de cadenas de valor y la participación del gobierno en ello. Esta investigación tuvo como objetivo analizar éstas situaciones. Para ello se utilizó la metodología de Matriz de Análisis de Política (MAP) desarrollada por Monke y Pearson, en  121 de huertas de naranja de riego (5,513 ha); considerando cinco tecnologías y un valor promedio del...

A Cautionary Note on Individual Transferable Quotas
Provedor de dados: Ecology and Society
Autores: Sumaila, U. Rashid; UBC Fisheries Centre, University of British Columbia; r.sumaila@fisheries.ubc.ca.
Individual transferable quotas (ITQs) are a type of catch share system, which is a tool used by some governments to manage fisheries. Technical reasons for taking a rather cautious approach to the implementation of ITQs have been provided previously. In the current contribution, I first highlight the strengths and weaknesses of ITQs and then provide suggestions on how to design and implement these quotas to mitigate their weaknesses. ITQs need to be designed carefully as part of a broad ecosystem-based management scheme to meet the three generally accepted objectives of modern fisheries management: ecological, economic, and social sustainability.

Intensive rearing of juvenile oysters Crassostrea gigas in an upwelling system : optimization of biological production
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bacher, Cedric; Baud, Jean-pierre.
Seasonal growth of juvenile oysters (Crassostrea gigas) kept in an intensive upwelling system was studied from 1984 to 1986 in 60 to 90-day growth experiments. Saline ground water was used to produce Skeletonema costatum which was injected as food into the water supplying the upwelling system. Oyster density, water flow, phytoplankton concentration, temperature and frequency of food addition were controlled. Oyster growth was analysed with multidimensional contingency tables and correspondence analysis. The factors, in order of decreasing influence on growth, were temperature, food concentration and oyster density. A rearing strategy was deduced from the growth analysis for summer and winter. In summer, the density of  120,000 oysters/m2, the flow rate of...

Do farmers provide agri-environmental services efficiently? – An economic analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kantelhardt,   Jochen; Eckstein,   Karin.
Agricultural land use does not only concern farmers, but also has a large number of social and environmental effects. Consequently, it is to be assumed that farmers have to use financial resources as well as labour in order to provide these services. Using the nonparametric method of Data Envelopment Analysis (DEA), we calculated the economic as well as the ecological efficiencies of farms and examined whether farms are able to succeed in combining ecological and economic efficiency. In addition to this analysis, we studied the driving factors of the respective efficiencies. The study was carried out in four typical production regions in Bavaria which vary in their proportions of grassland as well as their yield potential; thus, the study regions reflect a...

LARGE FARMS IN POLAND FOUNDED ON THE BASIS OF THE PROPERTY OF FORMER STATE - OWNED FARMS (PGRS)
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kagan,   Adam.
This paper presents economic results of three groups of large farms, in the years 2000-2005, which were founded on the basis of the property of former state – owned farms in Poland. They were divided according their legal and organisational form into: farms purchased, farms on lease and shareholder companies of the State Treasury. On the basis of the results of the analysis it was concluded that all three groups are economically effective, however, farms purchased, as a legal and organisational form, are protected against the production and market risk in the highest degree. Hence, the final direction of privatisation in Poland at the present stage of restructuring should be the purchase of farms. It does not mean, however, that there is a need to...

Autores: Simoes,   Andre Rozemberg Peixoto; Moura,   Altair Dias de; Rocha,   Denis Teixeira da.
The present work aimed to analyze the economical efficiency and the risk associated with three different cattle production systems (Cow-calf, Rearing and Finishing) in the Alto Pantanal (MS) Area. For that, the economical efficiency of each system was assessed and then the Monte Carlo risk simulation method was performed. The deterministic analysis showed that the Rearing system was the most profitable while the Finishing system presented the worst profit result. The Cow-calf system obtained an intermediate profit result. The risk economical analysis revealed the Cow-calf system as the lower risky system. On the other hand, the Finishing system showed the higher risk, presenting 28,7% of probability to obtain negative profit. The Rearing system showed the...

Land Rental Markets in India: Efficiency and Equity Considerations
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Akter,   Shaheen; Farrington,   John; Deshingkar,   Priya; Sharma,   Pramod; Rao,   Laxman.
Despite the fact that land rental is restricted to varying degrees in India, the participation in this market is widespread and it is observed to operate relatively efficiently in 12 villages studied in Andhra Pradesh and Madhya Pradesh. The estimated probit models predicted that the rental market transferred land to those with relatively smaller holdings, but greater ability to make productive use of land, more assets to invest, more adults available for labour and fewer off-farm opportunities. Also land is rented out predominantly to younger farmers and to farmers not involved in off-farm jobs. Renting in is predicted to be relatively higher in the villages which are remote and weakly integrated into mainstream infrastructure and institutions. Land...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Begum,   Ismat Ara; Buysse,   Jeroen; Alam,   Mohammad Jahangir; Van Huylenbroeck,   Guido.
This study estimates the technical, allocative and economic efficiency obtained from the Data Envelopment Analysis (DEA) approach using farm level survey data to a sample of 100 poultry farmers in Bangladesh for the year 2007. The results from the DEA approach show that there is substantial technical, allocative and economic inefficiency in poultry production in Bangladesh. The results of the study reveal that under constant return to scale (CRS) and variable returns to scale (VRS) specification, on average, the farms technical, allocative and economic efficiencies were 88%, 70%, 62% and 89%, 73%, 66% respectively. Thus the results indicate that efficiency scores vary substantially across the sampled farms. To explain some of these variations, the...

Technical, Allocative, and Economic Efficiency in Swedish Dairy Farms: The Data Envelopment Analysis Versus the Stochastic Frontier Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Johansson,   Helena.
Technical, allocative, and economic input efficiency scores were estimated for an unbalanced panel of Swedish dairy farms, using data envelopment analysis (DEA) and the stochastic frontier approach (SFA). By comparing the results it was concluded that when the entire dairy farm is studied the DEA is more appropriate to use since it does not require any particular parametric form to be chosen. The average DEA technical, allocative and economic efficiency indices were eventually found to be 0.77, 0.57, and 0.43 respectively. The influence of size on the efficiency scores was analyzed and significant evidence indicating a positive relationship between size and efficiency was found. Finally it was concluded that the main challenge facing the Swedish dairy...

Animals’ Health Control Efficiency in Northwest Portugal: A Two-stage DEA Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Costa,   Leonardo; Oude Lansink,   Alfons G.J.M.; Silva,   Elvira.
A two-stage approach is employed to analyze the efficiency of cooperatives responsible for ruminants’ disease control (OPP) at the farm level in Northwest Portugal. In the first stage, Data Envelopment Analysis (DEA) is used to estimate and decompose input-based overall inefficiency for each OPP. The input-based inefficiency measures are generated using the directional input distance function. In the second stage, the inefficiency estimates are regressed on environmental and organizational factors in order to explain efficiency differentials. Despite substantial environmental differences, the empirical results indicate that most cooperatives can reduce costs by improving scale efficiency and pure technical efficiency.

Economic Competition and Evolution: Are there Lessons from Ecology?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tisdell,   Clement A.
After discussing generally models in ecology and economics that combine competition, optimization and evolution, this article concentrates on models of intraspecific competition.  It demonstrates the importance of diversity/inequalities within populations of species and other environments for the sustainability of their populations, given the occurrence of environmental change.  This is demonstrated both for scramble (open-access) and contest competition.  Implications are drawn for human populations and for industrial organization.  The possibility is raised that within industry competition may not always exist between firms in all stages of the development of a new industry.  Policy implications are considered.  For example, it is argued that policies...

Preliminary principles to guide best practice water quality regulation from an economic perspective
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Coggan,   Anthea; Whitten,   Stuart M.; Greyling,   Tertius.
Regulatory regimes intended to enforce changes to land use or management impose costs on landholders and governments. Landholder costs comprise changes to capital equipment, changes to crop or enterprise management including direct compliance costs, opportunity costs of lost production, and transaction costs from informing themselves about regulatory requirements, potential compliance strategies and administration associated with implementation of these strategies. Governments must design and implement the regulatory framework along with an appropriate compliance structure and other associated costs. In this paper we apply economic theory, in particular relating to institutional economics and transaction costs, and the degree of heterogeneity landholder...

Autores: Schader,   Christian; Sanders,   Jurn; Offermann,   Frank; Lampkin,   Nicolas; Stolze,   Matthias.
This paper focuses on non-linear programming models and their suitability for ex-ante evaluations of agri-environmental policies on sector level. An approach is presented to compare organic farming payments as a multi-objective policy, with other, more targeted agri-environmental policies in Switzerland. The Swiss version of the comparative static sector-consistent farm group model FARMIS is able to group the sector’s farms into organic and non-organic farms and optimise them separately. CH-FARMIS is expanded with three modules particularly for this study: a) allowing for the simulation of uptake; b) integrating life cycle assessment data for energy use, eutrophication and biodiversity; and c) estimating the policy and farm-group-specific public...

DOES EFFICIENT WATER MANAGEMENT MATTER? PHYSICAL AND ECONOMIC EFFICIENCY OF WATER USE IN THE RIVER BASIN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cai,   Ximing; Ringler,   Claudia; Rosegrant,   Mark W.
With growing water scarcity and increasing competition across water-using sectors, the need for water savings and more efficient water use has increased in importance in water resources management. Improvement in the physical efficiency of water use is related to water conservation through increasing the fraction of water beneficially used over water applied, while enhancing economic efficiency is a broader concept seeking the highest economic value of water use through both physical and managerial measures. Physical and economic efficiency measures are both useful indicators for water management at the irrigation system and river basin level. However, the relationship between physical efficiency and economic efficiency is not always clear and the values...

Autores: Antle,   John M.; Capalbo,   Susan Marie; Mooney,   Sian; Elliott,   Edward T.; Paustian,   Keith H.
Under the Kyoto protocol of the United Nations Framework Convention on Climate Change the United States is charged with reducing emissions of greenhouse gases to seven percent below their 1990 levels by the period 2008-2012. These reductions could be met from many industries including agriculture. In this paper, an economic simulation model is linked to the CENTURY ecosystem model to quantify the economic efficiency of policies that might be used to sequester carbon (C) in agricultural soils in the Northern Great Plains region. Model outputs are combined to assess the costs of inducing changes in equilibrium levels of soil C through three types of policies. The first is a CRP-style policy that provides producers with per-acre payments for converting...

Economic efficiency of agricultural production in Brazil
Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Vicente,José R.
This study measures levels of technical, allocative and economic efficiency in agricultural crop production for Brazil in 1995. A nonparametric frontier model (DEA) under constant returns to scale was used. On average, the results suggest that the sector suffers from moderate technical inefficiency and from strong allocative inefficiency. If full technical efficiency were achieved, the crop production would increase by more than 30% over that obtained in 1995. Land and labor were overutilized, while fertilizers and pesticides were underutilized. Climate, soil conditions and irrigation use affected technical efficiency levels, and education in rural areas helped explain the extent of allocative efficiency. The state of São Paulo State was the only...

Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Pereira Filho,Carlos Augusto; Ferreira Filho,Joaquim Bento de Souza.
The main objective of this study was to identify and analyze the sources of inefficiency in family operated small agricultural properties in the Brazilian state of Bahia’s Recôncavo region from a sample of 44 producers. A non-parametric approach, in the context of cost minimizing behavior under constant returns to scale, was used to estimate the indices of technical, scale, allocative, and total (economic or cost) efficiency. Results indicated that the largest source small family farm inefficiency in the Recôncavo region is allocative inefficiency, that is to say, the non-observance of price relationships when making production decisions. On the average, 79.1% of these farms’ total inefficiency is due to allocative inefficiency, 9.3% to technical...

Autores: Haq,Shamsheer ul; Boz,Ismet.
ABSTRACT:  The primary purpose of this study was to analyze the efficiency level of tea farms operated by owners and shareholders, and to explore the effect of different decisional, structural and management factors on efficiency. The data were collected from a stratified sample of 138 tea farmers operated in Rize province Turkey in 2017. The data envelopment analysis (DEA) program was used to estimate the efficiency scores. Tobit model was used to explore determinants of technical efficiency. Results disclosed that farmers can reduce their inputs use by 43% without compromising their yield level. However, they have low economic efficiency (0.41). Shareholder-operated farms were highly efficient (0.76) than the owner-operated farms. The factors such as old...

Autores: Barros,Victor Ramos Sales Mendes de; Lana,Geraldo Roberto Quintão; Lana,Sandra Roselí Valerio; Lana,Ângela Maria Quintão; Cunha,Fabio Sales Albuquerque; Neto,João Virgínio Emerenciano.
The study aimed to evaluate the use of β-mannanase and mannan oligosaccharides (MOS) to replace growth promoters in broiler diets. Four hundred male Cobb broiler chicks were used, with initial weight of 45±1g, distributed in a completely randomized design with five treatments and eight repetitions of ten birds. The treatments were: basal feed; basal feed without growth promoter; basal feed without growth promoter + β-mannanase; basal feed without growth promoter + MOS; and basal feed without growth promoter + β-mannanase + MOS. The feed intake of the birds increased in response to dietary treatments compared to basal diet during the period 1-21 days of age. A higher weight gain and improved feed conversion was found at 42 days of age among birds that had...
