We derive and discuss a general, but simple geographical economics model with congestion, allowing us to explain the economic viability of small and large locations. The model generalizes some previous work and lends itself to analyzing the impact of public policy in terms of infrastructure...

We study the efficiency of oligopoly equilibria in congested markets. The motivating examples are the allocation of network flows in a communication network or of traffic in a transportation network. We show that increasing competition among oligopolists can reduce efficiency, measured as the...

An efficient congestion management system is a necessary condition to remove obstacles to the cross border trade of electricity in Europe and hence to move towards an internal electricity market. Locational marginal pricing (LMP)is progressively becoming the benchmark of congestion management in...

Airport congestion has been generally dealt in the literature in a similar fashion as road congestion. However, the phenomenon is quite different, because entry at airports is not random. Flight delays are a consequence of system overload, which is linked to profit maximization decisions of...

A seaport is awarded in a Demsetz auction to the operator bidding the lowest cargo-handling fee. The competitive auction is irrelevant if the port operator integrates into shipping and sabotages competitors, thus providing a motive for a ban on vertical integration. The paper shows that such a...

We provide a framework for analyzing two-sided markets that allows for different degrees of product differentiation on each side of the market. When platforms are viewed as homogenous by sellers but heterogeneous by buyers, we show that competitive bottlenecks arise endogenously. In equilibrium,...

Several researchers have contributed to the understanding of the mechanism of congestion in transmission and distribution networks while focusing on the development of system tools for congestion management. This research work is mostly devoted towards congestion management in distribution lines...
