We prove that a natural monopoly can set subsidy free pricing and sustainable pricing schedules in general economic environment. The setting is a multiproduct and multiple agent contestable market where demands are elastic and where rivals can enter the sub-markets composed by a set of the...

We provide some existence results of stable pricings for natural monopoly as defined in the theory of contestable markets. The main addings are based on the assumption of separated markets and the possibilities of entries. We borrow tools from cooperative game theory. Following the work of...

We prove the existence of subsidy free and sustainable pricing schedule in multiproduct contestable markets. We allow firms to discriminate the local markets that are composed by a set of the products line and a set of agents. Results are obtained under an assumption of fair sharing cost and...

A firm chooses a price and the product information it discloses to a consumer whose tastes are privately known. We provide a necessary and sufficient condition on the match function for full disclosure to be the unique equilibrium outcome whatever the costs and prior beliefs about product and...

What role can academics – especially in management research – have in management innovation ? Can they only be ex post critical analysts of the processes of inventing, experimenting, diffusing and implementing management models and techniques, or do they play a more active role ? From the...

This paper examines a combined set of corporate governance features that influence disclosure quality in a context of ownership concentration. Agency theory presents a theoretical framework linking disclosure decision to corporate governance mechanisms. Using a Multiple Correspondence Analysis...

We study competition in two sided markets with common network externality rather than with the standard inter-group effects. This type of externality occurs when both groups benefit, possibly with different intensities, from an increase in the size of one group and from a decrease in the size of...

A monopolist sells goods with possibly a characteristic consumers dislike (for instance, he sells random goods to risk averse agents), which does not affect the production costs. We investigate the question whether using undesirable goods is profitable to the seller. We prove that in general...
