At the theoretical level (respectively in the level of basic research), the aim of the submitted article is to form the theories of preferential choice in the area of higher utility vs. lower risk at interchangeable alternatives. Different or common features of utility vs. stochastic rating at agricultural subject are identified on the bases of this initial (axiomatically understood) theory. The consecutive (applicably usable) aim is then the commercialisation of the created theory of the preferential choice as a possible instrument which suits many times the controversial results and which brings the application of utilitarian and stochastic access...

Business, economic, and agricultural YES-or-NO decision making problems often require multiple, different and specific expertises. This is due to the nature of such problems in which decisions may be influenced by multiple different, relevant aspects, and accordingly multiple corresponding expertises are required. Fuzzy expert systems (FESs) are widely used to model expertises due to their capability to model the real world values, which are not always exact, but frequently vague, or uncertain. In this paper, different expertises relevant to the decision solution are modelled using several corresponding FESs. These systems are then integrated to comprehensibly...

After accession of the Czech Republic to the EU in 2004, the volume of agricultural foreign trade (AFT) in the CR increased significantly. In the past two years, the trend has changed under the influence of the global economic crisis affecting the European area. The first part of the paper is focused on the overall development in the period of 2004-2009. To assess the competitiveness of agrarian commodities in foreign markets in 2008-2009, an analysis was carried out with the use of the Balassa RCA Indicator (Revealed Comparative Advantage) and also Michaely Index, which indicates a certain degree of specialization in exports. A logarithmic method,...

It is the task of the economists to assess - under the conditions of the public budgets restrictions - whether the return rate of investments into public projects is sufficient enough in order to justify these projects in comparison to an alternative utilization of the expended resources. Complex e-learning systems, which include both the educational part and the subsequent verification of the students' knowledge, have lately been gaining on popularity in agriculture, in the public ICT projects from the field of education. The objective of the article is to explain the means of expressing economic efficiency of public projects on the example of establishing...

Agric. Econ. - Czech, 2011, 57(5):240-246 | DOI: 10.17221/39/2011-AGRICECON
The research presented in the paper was aimed at analyzing the economic performance of organic farms in the Czech Republic and at evaluating their operation in variants (i.e. including or excluding subsidies). The research was targeted solely at legal entities due to a limited data base. The performance of organic farms (individual kinds of legal entities) was compared by regions with the agricultural enterprises farming conventionally. The organic farms economic profit was as well assessed in relation to their field of activity. Based on the analysis made, the economic situation is more favourable for the organically farming enterprises. Their economic...
Efficiency evaluation in intensive growing of winter rape

Agric. Econ. - Czech, 2011, 57(5):247-257 | DOI: 10.17221/106/2010-AGRICECON
The aim of the paper was to evaluate the efficiency of winter rape growing which is based on the calculations and an analysis of production and economic indicators in the given branch. The development analysis of yields per hectare, costs, revenues and production profitability was carried out over the years 2003-2009 in the Agro Žlunice and it was compared with the results of the Czech Republic as a whole. In the enterprise, it deals with the traditional growing technology with a higher intensity of the intensification factors inputs in growing. Yields per hectare in the farm reached very favourable values which supported the stable position of the...
