The Dynamics of Conspicuous Consumption
Veblen Model: the Envy Rule

This is an exemplary model that shows our approach in the context of an intuitive and well-known problem. Primary sources: Friedman, 2001; see also Friedman and Yellin, 1997, and also Friedman and Yellin, 2001. (See References.)

There are two basic flavors of conspicuous consumption, as described in the literature: envy and pride. For the present, we restrict attention to the envy model. In our implentation of the model, the initial distribution may be constructed. (See the explanation below.)
