Abstract We consider an industry where an upstream firm determines the size of a network used by two downstream firms. We contrast ownership unbundling and legal unbundling, where the upstream firm maximizes its total profit, including the profit of its downstream subsidiary(ies), but does not...

Postal regulators set price controls in order to simultaneously ensure the provision of the universal service, promote competition and equity. We study the associated price control procedures in a model where the universal service provider offers both a single piece product and a business mail...

This paper studies the price structure in a postal sector with a monopolistic operator when customers can engage in worksharing. It presents simulation results obtained from an empirical model that is calibrated on data from the French postal sector. The optimal worksharing discount is...

We study the pricing and welfare implications of changing the VAT status of the national postal operator (NPO) from exempt to rated. We build a model where the NPO offers both single-piece and bulk mail to customers, some of them VAT rated, others VAT exempt. We solve for the optimal Ramsey...

We build a model where a postal incumbent offering single piece, transactional and advertising mail competes with postal entrants and with a firm offering an alternative medium. We solve for the optimal prices under various competition assumptions. We calibrate the model and provide numerical...

This paper studies the relationship between USO and environmental concern in the postal sector. We concentrate on the obligation to deliver mail on a D+1 basis. We examine how the USO should be designed to properly account for the environmental cost in a variety of situations ranging from a...

We provide a brief introduction to the current issue of the Review of Network Economics, which is a special issue devoted to the postal sector based on the sixth bi-annual Toulouse conference on “Competition and universal service in the postal sector.”
