A Stochastic Production Investigation of Fish Farms in Ghana AgEcon
Onumah, Edward E.; Acquah, H. de-Graft.
This paper considers the stochastic production frontier approach to analyse the technical efficiency and its determinants of fish farms in Ghana using a cross-section data of 150 farms. It considers the explicit effects of family and hired labour on production by setting the log-value of the zero-observation of these two sources of labour to zero with dummy variables. Results demonstrate that expected elasticities of mean output with respect to all input variables are positive and significant. Findings also show that family and hired labour used for fish farming in Ghana may be equally productive. Fish farms in Ghana are revealed to be characterised by technology with increasing return to scale. The combined effects of operational and farm specific factors...

An analysis of the Peruvian jungle cocoa farmers: Acopagro cooperative vs. intermediaries – a case of study AgEcon
Higuchi, Angie; Moritaka, Masahiro; Fukuda, Susumu.
n the Peruvian jungle, there are two main cocoa marketing channels: the intermediaries and the cooperative. The Acopagro Cooperative, a Peruvian organization, for example, has contributed to the shift from illegal crops like cocoa to an alternative crop like cocoa which gives small scale farmers a sustainable welfare. A survey of 243 farmers in Juanjui, San Martin-which is the main cocoa production area in Peru-was carried out between December 2009-January 2010. This study analyzes Peruvian cocoa farmers’ socio-economic characteristics as these attributes affect their decision-making process in the cocoa commercialization for their self-improvement and evaluates if the farmers’ participation in Acopagro or not influences the increment of the cocoa...

Analysis of the Method for the Selection of Regions with Concentrated State Aid AgEcon
Krejci, Igor; Voriskova, Andrea.
The paper deals with the analysis of a method used by the Czech Government and the Ministry for Regional Development to select regions with concentrated state aid. It contains a comparison with several different basic methods of multi-criteria decision-making (MCDM). The analysis focuses on a mathematical algorithm of the established MCDM method and does not consider validity of any selected socioeconomic criteria and their weights. Both the strengths and weaknesses of the used MCDM method are presented. The paper includes a simple proposal of the modification of the examined method that will prevent incorrect data normalisation used for region’s evaluation before revision in 2010. Data used for all calculations were obtained from the Ministry for Regional...

Analysis of the Relationship between State Budget and Trade Balance of Libyan Economy (Period: 2000 – 2008) AgEcon
Maitah, Mansoor; der Ali, A..
The subject of the relationship between state budget and trade balance is important as economic subject, not only at the level of developing countries, but also at of advanced ones, too. Such importance emerged clearly when 1980s witnessed in United States of America a deficit in both state budget and trade balance, which was called at that time as the twin or dual deficit. We can say that the analysis of relationship between state budget and trade balance states the extent of mutual effect between financial and trade policies of any economy, namely; any change in the outcome of either one may affect the other in the same degree. To put in other words, the instruments of financial policy represented by total incomes and total expenditures can affect the...

Assessment of agricultural land fund in the Czech Republic, importance and future AgEcon
Voltr, Vaclav.
Assessment of land depends on the production function of soil and additional connections given by environmental requirements, by the evaluation of public goods or by the requirements for formation a fair tax policy and even by the interests of landowners. Analysis of coherences during the soil appraisal shows a relatively strong dependence on the development of year-by-year yields and cost including subsidy policy, which is strongly reflected in the grasslands. Development of subsidies does not basically influence a long- term return and costs ratio for the production on arable land. The requirements for formation of prices are given due to the need for stability of the mutual relations between the quality of soil and climatic conditions, which manifests...

Classification of the EU countries labour markets AgEcon
Kaba, Bohumil.
The objective of the paper is to classify the labour markets of the EU member states on the basis of selected employment and unemployment indicators. In order to achieve the study target, the adequate multivariate exploration procedures have been chosen. In the first part of processing original data, principal component analysis (PCA) was employed. PCA is a multivariate statistical procedure used to reduce the number of observed variables into a smaller number of uncorrelated variables with a minimum loss of information. Moreover, the PCA results can be used for effective ranking of the EU countries according to observed indicators of labour markets. This paper describes the crucial steps in PCA and procedure for ranking mentioned and it reviews how...

Coherent Quantitative Analysis of Risks in Agribusiness: Case of Ukraine AgEcon
Tarasov, Arthur.
Modern methods of quantitative risk analysis, specifically value-at-risk and expected shortfall approach, provide comprehensive and coherent risk evaluation throughout entire distribution of outcomes and can take agricultural business from the realm of uncertainty to specific, quantified risks. Monte Carlo simulation with autocorrelation of standard deviation shows the best results in risk modeling and is used for this research. The analysis showed that production risk is systemic within climatic regions of Ukraine with coefficients of correlation ranging from 0.25 to 0.85. Yield correlation among crops in several oblasts is low to negative, creating opportunities for diversification. However, positive price-yield correlation is dominant for agricultural...

Consequences of BSE disease outbreaks in the Canadian beef industry AgEcon
Stephen Clark, J.; Cechura, Lukas.
This study examines farm to wholesale prices spreads to measure the impact of the BSE disease outbreak on the Canadian beef industry. The study uses structure break tests developed by Gregory and Hansen (1996) and Hansen (1992) examine possible breaks within co integrating relationships. The study finds evidence that the industry began realignment as a result of the UK BSE disease outbreak, and the Canadian BSE disease outbreak was simply the largest realignment of the process beginning with the UK disease outbreak. However, the only statistically significant break was the BSE disease outbreak itself in May 2003. Stability was not restored until the border was reopened in 2005. Specific results indicated that the processing sector exploited the border...

Data, Information and Knowledge in Agricultural Decision-Making AgEcon
Houskova Berankova, Martina; Houska, Milan.
It is very important to work with data, information and knowledge correctly, when a decision model is used as a support for managerial decision-making. Unfortunately, these terms are understood differently in various branches; particularly, the definitions of knowledge are very different. It causes problems in praxis; it is not clear, in which case data processing, information or knowledge/expert systems are appropriate to use. In this paper we introduce modern approaches to indentifying these terms. The objective of the paper is to identify data, information and knowledge in decision-making process, particularly in multiple-criteria decision-making model, to help users of such models to better understand it. To reach this objective, we need to provide...

Varallyai, Laszlo; Herdon, Miklos.
The 35 percents of EU total population use the advanced Internet services. This rate is very low and has to increase in the next years, because the employed person needs ICT user's skills. At the first level the digital literacy and at the second level the higher knowledge of ICT acquiring is very important, because nowadays, without these abilities it is not so easy to get qualified jobs in Hungary. In the information society it is very important to measure the digital literacy. For this measuring we have to ask the users to evaluate their own knowledge. In the World Internet Project evaluation we did not find a significant disparity between the evaluation of average Internet knowledge usage and that of the computer usage. In both cases, most people...
