- We show that Grandmont's (1992) model of demand heterogeneity can be a model of heterogeneity in the complementary or sign-balancing sense. By this we mean that heterogeneity has the following form: given a change in price, agents respond heterogenously - some by increasing their expenditure share on a good, others by diminishing it, so that the average expenditure share of all goods remain approximately unchanged.
