Zmiany międzygrupowych relacji cen dóbr konsumpcyjnych

Abstract

The article contains the findings of empirical studies conducted in the period 1986-1987 in the field of an evaluation of influence exerted by the reform in the retail prices system on changes in their relations in an intergroup approach and an evaluation of the role played by various price-formative factors, which could cause changes in these relations. The findings in question allowed to formulate the following conclusions: - In the period under survey, the prices of non-food items were growing relatively faster than prices of foodstuffs. That is an indicator of unfavourable relations of prices from the viewpoint of rationalization of consumption and its effectiveness-promoting impact. - The cost factor does not have any significant influence on changes in relations of pricess, and especially in the case of non-food items. - The financial effect (gross profit) is of decisive importance for occurring changes in relations of prices.
