In this paper we develop a new theory of static equilibrium in congested transportation networks. Our considerations are based on a physical meaning of the flows rather than on an artificially chosen model of travel time functionsl We introduce a concept of the stable equilibrium and prove the...

This paper presents a spatial model to study imperfect competition with congestion. The model is used to examine the price and wage setting of subcenters of a city. Residents live in a city while they shop and work in subcentres. Each subcenter offers one differentiated product and one...

The purpose of this paper is to study the effects of tolling road use on a parallel road network where each link can be tolled by a different government. Using both theoreticaland numericalmo dels, the paper analyses the potential tax competition between countries that each maximise the surplus...

The purpose of this paper is to compare the interaction between pricing and capacity decisions on simple serial and parallel transport networks. When individual links of the network are operated by different regional or national authorities, toll and capacity competition is likely to result....

We consider the problem of designing a 2-stations Automated Guided Vehicle System (AGVS). The AGV System consists of a pool of vehicles that transports products from one station to the other station through an unidirectional guidepath.

Since the introduction of a formal commitments procedure in EU an- titrust policy (Article 9 of Council Regulation 1/2003), the European Commission has extensively settled cases of alleged anticompetitive practices. In this paper, we use a formal model of law enforcement (Be- bchuk, 1984; Shavell,...

The plea bargaining procedure, namely the viability of a stage of bargaining between prosecutor and defendant in criminal suits, is analyzed in the framework of a two-sided incomlete information game.

Benchmarking methods, and in particular Data Envelopment Analysis (DEA), have become well-established and informative tools for economic regulation. DEA is now routinely used by European regulators to set reasonable revenue caps for energy transmission and distribution system operators. The...

We consider a nonlinear vector model called the logistic vector smooth transition autoregressive model. The bivariate single-transition vector smooth transition regression model of Camacho (2004) is generalised to a multivariate and multitransition one. A modelling strategy consisting of...

We assess the predictive accuracy of a large number of multivariate volatility models in terms of pricing options on the Dow Jones Industrial Average. We measure the value of model sophistication in terms of dollar losses by considering a set 248 multivariate models that differ in their...
