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...

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 study the optimal manipulation rules of a public firm’s objective function in a mixed duopoly with imperfect product substitutability. We compare the solutions under quantity and price competition, and the way in which they are affected by the degree of product substitutability. This...

We study the optimal manipulation rules of a public firm’s objective function in a mixed oligopoly with imperfect product substitutability. We start with a baseline duopoly model and compare the solutions under quantity and price competition, and the way they are affected by product...

In this paper we extend the analysis of the standard model of spatial discrimination with quantity competition along the linear city to the case in which the unit transportation cost is greater than one. We show that in such a case the unique subgame perfect Nash equilibrium in locations is a...

This paper contrasts the descriptive and normative properties of the New Keynesian general equilibrium models with those of other Keynesian paradigms, such as the neoclassical sintesi and the post Keynesian ones. We argue that the co-ordination failures, which are pivotal within the New...

The paper proves the existence of a subgame perfect Nash equilibrium in a vertically differentiated duopoly with uncovered market, for a large set of symmetric and asymmetric distributions of consumers, including, among others, all logconcave distributions. The proof relies on the 'income share...

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...
