The aim of the paper is to verify and explain the actual effects of the Sweezy oligopoly model and its eventual impact on the consumer demand and the structure of the food supply of chain stores. The methodology of the paper is based on a comparative analysis of the structure of commodities of chain stores in the Czech Republic in terms of consumer demand and its change over time. An example of this model behaviour of firms may be the competition between two supermarket chains Billa and Kaufland in the market with private label products (e.g. pork meat). Results of the analysis of the Sweezy model imply that the change in company costs due to higher...

The study empirically investigates the relationship between the relative GDP share of agriculture and the unemployment rate in a sample of ten Central and Eastern European countries. Utilising the annual data for the sample period 1996-2013, the empirical analysis is carried out using the dynamic panel regression analysis and the Granger causality tests. The estimation results based on the alternative specification of regression equations for the unemployment rate suggest that the unemployment rate is negatively related to the relative GDP share of agriculture. In addition, a similar effect has been obtained for some other explanatory variables we...

The paper analyses the current position of the Russian Federation in the global market of agricultural products and foodstuffs with the accent on the comparative advantage of Russian agricultural exports in relation to specific regions and states. The key purpose of the research is to classify the most significant changes in the structure of Russian agricultural exports. The results show that the structure of Russian trade is changing continuously and evolving along with the process of economic transformation and trade liberalization. Exports become less diversified and are concentrated in a few segments. From the perspective of comparative advantage,...

Liberalization of the market, as a consequence of the achieved trade agreements with the members of the European Union and the Central European Free Trade Association, had a significant effect on the foreign trade exchange of the Serbian agri-food products. In order to determine the liberalization effects on the export of agri-food products of Serbia, a gravity model of the export of these products is estimated using econometric methods for the panel data. In order to find the sections, as well as the advantageous parts of the international market, the comparative advantages of agri-food products in the particular groups of countries are dynamically...
