This paper provides a limit result for the provision of a public good in a mechanism design framework as the number of agents gets large. A canonical example for a public good that is produced with a direct provision technology is Open Source Software.

This paper investigates the effect of spillovers in a model of endogenous technical change resulting from learning or network effects on the existence of a lower bound to market concentration.

This paper looks at competition in the telecommunication industry. We determine the equilibrium pricing parameters for a duopoly situation with a particular emphasis on the role of competitively chosen non-reciprocal access prices. In the symmetric equilibrium the networks optimally choose...

This paper looks at the effects of entry on welfare in the telecommunication industry. The equilibrium pricing parameters for an incumbent (state) monopoly and for a duopoly situation are determined in which access charges are chosen non-reciprocally. A welfare comparison between the monopoly...

This paper looks at competition in the Telecommunications industry with non-linear tariffs and network based price discrimination where one of the networks has a relative advantage. We investigate profit-maximizing network pricing behaviour, in particular competitively chosen, non-cooperative...
