Income distribution affects market demand and its elasticity, and, as a consequence, the optimal behaviour of firms and market equilibrium. This paper focuses on the effects of income polarization, and presents a model where - for any unimodal density function describing income distribution of...

We analyze the direction of the co-movements of price and output in a monopolistic market when an expansive shock occurs. Price and quantity patterns are shown to depend on the consumers? income distribution. In particular, a low degree of income dispersion is associated with price and quantity...

We introduce non-homothetic preferences in the Dixit-Stiglitz model of monopolistic competition, and enquire about the effects of a change in income dispersion on the firms' optimal decisions and market equilibrium. Income dispersion, modelled as a mean preserving spread, is shown to affect only...

We analyze the effects of income concentration and income dispersion on market demand and its elasticity. We show that, following an increase in income concentration towards the middle (measured by variations in mean preservingspread), the increase in demand faced by firms which serve at the...
