A small region has a high cost monopolistic electricity generator. It is connected through a low capacity transmission line with a large, competitive low cost region. Access to the transmission line is auctioned. I show that, if consumers arbitrate on the regional price differences, the...

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...

Motivated by the failure of competition to emerge after the natural gas market in the Czech Republic was liberalized, I explore the impact of natural gas storage ownership and upstream competition on the downstream level. I extend standard Cournot models to understand current and likely future...

This paper analyses whether scale economies exists in the UK telecommunications industry. The approach employed differs from other UK studies in that panel data for a range of companies is used. This increases the number of observations and thus allows potentially for more robust tests for...

Complexity science is widely used across the policy spectrum but not in antitrust. This is unfortunate. Complexity science enables a rich understanding of competition beyond the simplistic descriptions of markets and firms proposed by neoclassical models and their contemporary neo-Brandeisian...

We analyze the optimal location choice of a monopolistic firm that operates two platforms on a two-sided market. We show that the optimal platform locations are equivalent to the one-sided benchmark if both sides are either restricted to single- or multi-homing. In the mixed case (one side...
