The article is focused on price transmission within milk commodity chain in the Czech Republic. The article distinct on milk products with low value added -cow milk/paper box milk and products with higher value added -cow milk/butter. Price transmission is measured by the coeffi cient of elasticity of the price transmission (EPT); price transfer is examined in demand as well as supply direction. Next part of the analysis measures price diff erences (by coeffi cient determination -R 2 ) in supply direction. Last step in this analysis is the impact of time delay at the price transmission process (measured by R 2 ). The price transmission is asymmetric in the supply direction on both parts of commodity chain (EPT = 0.29 and 0.62), in the demand direction is more symmetric (EPT = 0.31 and 1.02). The assumption of better transfer of positive price changes was confi rmed. At the commodity chain of milk/dairy products the time delay is not so much important. With both tested commodity chains there was found higher power of downstream markets, proving demand driven behaviour of these commodity chains, and there was detected oligopsony market structure as well. The data represent monthly prices on both chosen vertical levels in the period of 1/2000-8/2013.
