Most theoretical studies of traffic congestion during the morning commute have been limited to one origin, one destination, and one route. This paper is the first to analyze systematically user equilibrium, system optimum, and various pricing régimes for a simple network of routes in parallel....

We analyse the incidence of ad valorem and unit excise taxes in an oligopolistic industry with diffentiated products and price-setting (Bertrand) firms.

This paper considers the relative efficiency of ad valorem and unit selective sales taxes in imperfectly competitive market. We provide a simple proof of the proposition that ad valorem taxes are welfare-superior to unit taxes in the short run whenproduction costs are identical across firms.

Les quelques remarques presentees ici veulent attirer l'attention sur certains effets remarquables des styles de decision lorsque la decision est elle-meme un processus collectif, qui prend place dans un paysage reconnaissable a certaines caracteristiques specifiques. Le texte donne quelques...

Cet article presente un modele visant a mesurer l'impact de l'accessibilite dans un systeme de transport. Le modele propose integre deux elements majeurs: le prix des biens et le cout de transport. L'impact de ces deux variables a ete explore sous diverses directions: variation d'accessibilite,...

We consider a market in which a public firm completes against private ones, and ask what happens when the public firms is privatized. In the short run, privatization is harmful because prices rise: the disciplinary role of the public firm is lost. In the long run, privatization, leads to further...

This paper presents recent developments of the dynamic traffic simulation model METROPOLIS. This tool is based primarily on the modeling and analysis of information learning and processing by road users. This simulation tool depicts the morning peak commute in large urban areas. Route choice and...

This paper extends research in dynamic traffic modeling using METROPOLIS, a dynamic simulation tool. We briefly present an overview of the original departure time choice model introduces by W. Vickrey (1969) for a single O-D pair. Using this framework for our analysis, we explore how the...
