In the studies, the method of comparing price trends for the years 1991–2008 was used. The analyses which were carried out showed that the potato market can be assessed as an efficient market. The pace of price growth of potato exceeds the price growth of alternative agricultural products. The reduction of the market share of producers in retail prices is not observed in the market of fresh potatoes. The highest economic efficiency for producers is ensured by the production of early crop potatoes. At the same time, on the potato market there are many efficiency barriers to potatoes in terms of low ability to compete on the international market. Lower cost of sales transactions causes a gradual growth of links with potato buyers by contract.application/pdfenmarketevaluation of efficiencyprice trendspotatoinfo:eu-repo/semantics/article
