The paper deals with a problem of producers' sensitivity to changes in buying-in prices. Prices are one of the factors influencing agricultural producer's decisions, and problems discussed in this paper are important in agricultural economics, because they complement price elasticity of production analysis. Usually in the analysis of producers' sensitivity to changes in buying-in prices, the sensitivity of income is taken into account, as well as price intervals, in which the supply of agricultural products is characterized by high or low elasticity. We assume that the function of the individual agricultural producer is to maximize income. The problem of producers' sensitivity to changes in prices is independent of methods of price determination (both market and institutional factors). Predicting and measuring producers' reactions are considered key issues, that allow to make conclusions concerning adequate instruments of policy intervention in agriculture. The paper deals with producers' reactions in the short run.
