The conducted correlation-andregression analysis revealed a close inverse connection
between the functional characteristic "share of the
expenditures for food and non-alcoholic beverages in
the structure of the total expenditures of the households" and the factorial characteristic "GDP per capita by purchasing power parity, at constant prices".
The response of the share of food expenditures in the
structure of the total expenditures of the households to
per capita GDP growth corresponds to the law of diminishing returns. The pattern is manifested in the
long-term period.
