Markets of Joint Products: Theoretical Model and Policy Implications

The article considers the phenomenon of price behavior on markets of joint products. It is shown that conclusions about the nature of economic entities' behavior on this kind of markets could be inaccurate if their characteristics such as joint costs and correlation of demand conditions on markets mentioned are not taken into account. For this purpose a theoretical model, built according to basic microeconomic principles, is applied. It provides an opportunity to reveal - without further new institutional analysis - that the reason for price deviation from a competitive level does not always lie in actions restricting competition.
