This paper studies the efficiency impacts of private toll roads in initially untolled networks. The analysis allows for capacity and toll choice by private operators, and endogenizes entry and therewith the degree of competition, distinguishing and allowing for both parallel and serial...

This paper considers the use of ‘long-run cost functions’ for congested networks in solving second-best network problems, in which capacity and tolls are instruments. We derive analytical results both for general cost and demand functions and for specific functional forms, namely Bureau of...

This paper investigates regulation by auctions of private supply of congestible infrastructures in two networks settings: 1) two serial facilities, where the consumer has to use both in order to consume; and 2) two parallel facilities that are imperfect substitutes. There are four market...

Der Schwerpunkt dieses Beitrags liegt auf den Märkten für Verkehrsinfrastrukturkapazitäten. Mittels geeigneter Preisinstrumente gilt es, eine effiziente Allokation knapper Infrastrukturkapazitäten sowie die erforderliche Kostendeckung anzustreben. Zunehmende Skalenerträge beim Ausbau einer...

Zu viele Autos, Staus in den Innenstädten, schlechte Luft, hohe Schadstoffemissionen: In vielen Städten und Kommunen droht ein Verkehrskollaps. Neue Verkehrskonzepte werden dringend benötigt. In einigen Städten werden unterschiedliche Ansätze verfolgt, um den privaten Autoverkehr in den...

We analyze the phenomenon of hub dominance by developing a model relating faresto distance, using the mainleg of intercontinental flights for scaling purposes. Our results indicate thatat least some of the major Europeancarriers place a mark up on flights originating from or going to their hubs.

As vehicles become more fuel-efficient and overall levels of travel stagnate in response to increases in fuel prices, conventional sources of revenue for transportation finance such as taxes on motor fuels have been put under increasing pressure. One potential replacement as a source of revenue...

In this paper we introduce an activity-based modeling approach for evaluating the traveler costs of transport network disruptions. The model handles several important aspects of such events: increases in travel time may be very long in relation to the normal day-to-day fluctuations; the impact...
