Summary/Abstract: The paper attempts to analyze consumer demand using a complete demand system AIDS. The complete demand system is the right tool for the analysis of consumer demand because it takes into account the phenomenon of substitutability and complementarity. The research was based on household microeconomic data collected by GUS (the Polish Central Statistical Office) in the period 1999-2012. Additionally, a complete demand model has been extended by the demographic variable and the time variable. The problem of zero expenditures and the collinearity of variables were described in the paper. The results show that taking into account the phenomena of substitutability and complementarity allows a better understanding of complex interactions occurring in the market for consumer goods and services.
