Intergenerational linkages in consumption patterns and the geographical distribution of surnames

This paper attempts to detect the existence of links in consumption patterns between generations. Preferences over consumption goods may be determined by the preferences of parents and/or by preferences arising from the environment. We propose an indirect methodology to overcome the lack of data on consumption choices of dynasties, i.e., parents and their adult offspring. This new approach is based on the analysis of the correlation between the geographical distributions of surnames and consumption choices. We show that there is no significant intergenerational link on consumption patterns for non-food goods. Our results also suggest that there is a link between parents' and children's preferences over food items.

► We study links in preferences over consumption goods between generations. ► Preferences are determined by the preferences of parents and/or by the environment. ► We analyze the correlation between the distribution of surnames and consumption. ► We find intergenerational links for food goods.
