【 摘 要 】

Studies of the demand relations on the consumer markets bring much useful information. The concept of the elasticity coefficients is frequently used for the quantitative analysis of the demand sensitivity. Formulation of the investigated demand functions is very important for the evaluation of the demand elasticity. Within net consumer demand (consumer purchase), it is possible to differentiate the physical and expenditure forms of the demand functions. The paper is focused on the theoretical and methodological backgrounds of the evaluation of price-demand elasticity under the physical and expenditure definitions of the demand relationships. In this paper, the relationship between the coefficient of the price elasticity of demand in the physical form and the coefficient of the price elasticity of demand in the expenditure form is determined and studied. The derived formula is tested using the USDA database.
