Essays on microeconomics of transportation

Résumé

The manuscript is organised into five sections. The first section is an introduction presenting my scientific position, my teaching activities, the management of studies, the supervision and animation of research, and finally the recent creation of the Association Française d'Economie des Transports of which I am vice-president. Sections 2, 3 and 4 present a collection of my recent contributions to transport economics research. Section 2 includes three articles analysing different manifestations and effects of congestion in public transport. The first looks at the effects of public transport congestion on user satisfaction, using a survey of stated preferences collected on the platforms of the Paris metro. The second studies the effects of congestion on users' choice of departure times. A microeconomic model is used to define the decentralised equilibrium and the social optimum, and to study the mechanisms for refocusing the social optimum. The third article examines the effects of congestion on the economies of scale of urban public transport operations. A microeconomic model is used to show that congestion phenomena (longer travel and waiting times, discomfort) appear when demand increases significantly, leading to diseconomies of scale and calling into question the subsidies granted to passengers during hyper peak periods. Section 3 contains two articles that study individual preferences for carpooling. The first article analyses these preferences for short-distance carpooling and the second for short-distance carpooling, using surveys of stated preferences collected through web-surveys. These preferences are analysed mainly by estimating the opportunity cost of travel time (or value of travel time) specific to each mode. Section 4 includes two papers that study the efficiency of regional rail services. The first studies price and frequency efficiency using a partial equilibrium model calibrated on two corridors: Ghent - Brussels in Belgium and Grenoble - Lyon in France. The second studies the productive efficiency of TER regional branches in France using a stochastic production frontier model. Finally, Section 5 presents my research perspectives in terms of method, topics and current and future projects.
