The estimation of the Marshallian demand functions for the selected foodstuff groups according to the households income quartils

The article deals with the modelling of demand for the food group of milk and milk products and the food group of meat, meat products, eggs and fish using the Marshallian demand functions for the individual income quartils of Slovak households. The criterium for the foodstuff groups selection is their position in the Healthy Eating Pyramid which is one of the recommended optimal food basket forms. We suppose that the significant income differentiation of households will manifest as different consumer behaviour in the food market. The analysis confirms this hypothesis.
