  We empirically investigate distributions of individual consumption
expenditure f or four commodity categories conditional on fixed income levels.
The data stems from the Family Expenditure Survey carried out annually in the
United Kingdom. W e use graphical techniques to test for normality and
lognormality of these distributions. While mainstream economic theory does not
predict any structure for these distributions, we find that in at least three
commodity categories individual consumption expenditure conditional on a fixed
income level is lognormally distributed.
