Undertakings may restrict competition by cooperating with their competitors or by interfering with their ability to compete. In both cases, their ultimate goal is to raise the price they charge for their products or services. Therefore, the main concern about both collusive and exclusionary...

‘Robot cars' are cars that allow for automated driving. By allowing cars to safely drive closer together than human driven ‘normal cars' do, robot cars raise road capacity. By allowing drivers to perform other activities in the vehicle, they lower the value of travel time delays (VOT). We...

This paper studies the role of taxation in durable good markets with dynamic monopolies. By conditioning the marginal tax rate on the volume of trade, the social planner can provide incentives for the monopolist to abandon sequential screening and clear the market immediately in unique...

Robert Bork's Antitrust Paradox (1978) has been justification for lack of antitrust behavior for over four decades. His test essentially asks if consumers are harmed by the pricing practices of the firm in the market in which they purchase the good or service. Even if these firms are monopoly or...

The so-called excess-entry theorem (Mankiw and Whinston 1986, Suzumura and Kiyono, 1987) establishes conditions guaranteeing that more firms enter a homogeneous Cournotoligopoly in equilibrium than a benevolent government prefers. We generalise the approach and analyse the behaviour of a...
