In spite of its importance to the retail sector, there has been relati
vely little research on the economics of Christmas Season gift-giving.
The one exception is Waldfogel (1993), The Deadweight loss of Christm
as, American Economic Review, 83, 1328-1336, who found a substantial a
mount of deadweight loss associated with Christmas gift-giving. Here i
t is shown that the Waldfogel study is incomplete and alternative mode
ls of consumer choice theory which better explain Christmas gift-givin
g are identified. Although the standard neoclassical and altruistic mo
dels predict no relationship between the population of children and pe
r capita Christmas spending, a model is developed that includes non-pe
cuniary externalities and predicts that children have a positive impac
t on Christmas gift-giving. This prediction is supported by empirical
evidence.
