We enquiry about the effects of first and second order stochastic dominance shifts of the distribution of the consumers’ willingness to pay, within the standard model of a market with network externalities and hump-shaped demand curve. This issue is analyzed in the polar cases of perfect...

We consider the interplay between income distribution and optimal commodity taxation, linking equity issues to optimal taxes through the effect of income distribution on market demand and its price elasticity. We find conditions to conciliate the equity and efficiency tradeoff and to assess the...

Esteban (1986) introduced the notion of income share elasticity as a function pi which can describe the size distribution of income. On the other hand, indices of first or second order stochastic dominance are widely used to describe shifts in income distribution, to which inequality measures...

The paper analyses the effects of income concentration on the behaviour of a duopoly with vertical product differentiation and uncovered market. By using a trapezoid distribution, we solve explicitly for market equilibrium as a function of a mean preserving spread of the income distribution. We...

In "The Economics of Imperfect Competition", Joan Robinson argued that an increase of the consumers' incomes should make demand less elastic - which, although reasonable about individual demand as an assumption on preferences, suggests a role for income distribution as far as market demand is...

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

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, modeled as a mean preserving spread, is shown to affect only...
