In this paper we systematically study the vertical integration and sabotage decisions of a regulated bottleneck monopoly that sells access to independent downstream firms. Our results reconciliate a set of seemingly contradictory findings of the literature. We show that unless the monopoly's...

Consider a bottleneck monopoly whose access charge is regulated above marginal cost and provides access to an oligopoly of downstream firms. Should the monopolist be allowed to vertically integrate into the downstream market? For the general run of oligopolistic market structures, we show that a...

An essential facility produces 'access', an essential input used by a competitive downstream industry. The access charge is regulated. The essential facility can vertically integrate into the downstream segment and sabotage rivals increasing their costs.We systematically study the vertical...

There are many industries in which potentially competitive segments require services provided by natural monopoly bottlenecks (essential facilities). Since it is difficult to regulate these facilities, developing countries are using Demsetz auctions, where the facility is awarded to the firm...

In many circumstances, a principal, who wants prices to be as low as possible, must contract with agents who would like to charge the monopoly price. This paper compares a Demsetz auction, which awards an exclusive contract to the agent bidding the lowest price (competition for the field) with...

Regulating seaports is difficult in general, even more so for the weak regulatory institutions common in developing countries. For this reason some countries have awarded these facilities via Demsetz auctions, to the port operator that bids the lowest cargo-handling fee. A major concern with...

A principal, who wants prices to be as lowas possible, contracts with agents who would like to charge the monopoly price. The principal chooses between a Demsetz auction, which awards an exclusive contract to the agent bidding the lowest price (competition for the field) and having two agents...
