In the study of a geographically aggregated market, the choice of a representative household leads to consider the
whole territory as a single, homogeneous one. However, there are reasons to believe that regional preference differences do
exist when there are important cultural and climatic differences among regions, and, historically, most of them have
developed and enriched their own cuisines and food preferences, as in Spain. The econometric analysis of separate demand
systems of meat and seafood consumption for the aggregate Spain and for three regions, shows that differences are reflected
in the patterns of0 complementarity and substitution.
