We discuss network neutrality regulation of the Internet in the context of a two-sided market model. Platforms sell broadband Internet access services to residential consumers and may set fees to content and application providers on the Internet. When access is monopolized, cross-group...

We consider a repeated regulation model in an oligopoly under asymmetric information with pollution. An iterative procedure is proposed where the regulator designs stationary taxes, and firms are not required to be perfectly rational. They can form and update simple beliefs about their...

An important reason for the Internet's remarkable growth over the last quarter century is the "end-to-end" principle that networks should confine themselves to transmitting generic packets without worrying about their contents. Not only has this made deployment of internet infrastructure cheap...

We show in a simple model of entry with sunk cost, that a regulator prefers limiting the output, or capacity, of the incumbent firm rather than imposing a "Minimum Quality Standard" in order to help the entrant to provide high quality. As a by-product, our analysis makes a contribution to the...

This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behavior of firms once they are in the market. We adapt the Clarke-Groves mechanism, characterize the optimal mechanism that maximizes the...

We study price-cap regulation in a market in which a vertically integrated upstream monopolist sells an essential input to a downstream competitor. In the absence of regulation, entry benefits both firms, but may be detrimental to downstream consumers because the upstream monopolist can set a...

This study aims to examine urban zoning within a linear city in a Bertrand duopolistic competition framework with price discrimination and linear transportation costs. It analyses the effects of introducing an environmental area where economic and residential activity are not allowed. The...

Like other network industries, the European gas supply industry has been liberalised, along the lines of what has been done in the United Kingdom and the United States, by opening up to competition the upstream and downstream segments of essential transmission infrastructure. The aim of this...
