Built on the location model, this paper studies the rivalry of two firms in an industry through two-part tariffs. It is found that kinky profit functions are responsible for the coincidence of imperfectly competitive equilibrium and cartelization outcome. A duopoly likely results in higher entry...

This paper proposes a tractable alternative to Cobb-Douglas utility to resolve the problems of lack of reservation price and income effects in demand functions derived from Cobb-Douglas utility or quasilinear utility. Another advantage of this alternative is that it provides a closed-form...

We extend Armstrong's (1996) result on exclusion in multi-dimensional screening models in two key ways, providing support for the view that this result is quite generic and applicable to many different markets. First, we relax the strong technical assumptions he imposed on preferences and...

The paper developes the model of optimal monopoly pricing under the viscous demand and customers turnover. The main findings are that the monopoly prices high during a fad, fads, however, are short lived
