This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to unretire, i.e., unexpectedly return to work. It also shows that when myopia about habit formation leads to...

This paper examines the correlated random coefficient model. It extends the analysis of Swamy (1971, 1974), who pioneered the uncorrelated random coefficient model in economics. We develop the properties of the correlated random coefficient model and derive a new representation of the variance...

A wide variety of social protection systems coexist within the EU. Some member states provide social insurance that is of Beveridgean inspiration (with universal and more or less flat benefits), while others offer a system that is mainly Bismarckian (with benefits related to past contributions)....

This paper studies the second-best problem where not all links of a congestedtransportation network can be tolled. The second-best tax rule for thisproblem is derived for general static networks, so that the solution presentedis valid for any graph of the network and any set of tolling points...

Conventional economic wisdom suggests that congestion pricing would be an appropriate response to cope with the growing congestion levels currently experienced at many airports. Several characteristics of aviation markets, however, may make naive congestion prices equal to the value of marginal...

This paper develops a continuous-time -continuous-place economic model of road trafficcongestion with a bottleneck, based on car-following theory. The model integrates twoarchetype congestion technologies used in the economics literature: 'static flow congestion',originating in the works of...

Conventional economic models of traffic congestion assume that therelation between road use and speed is a technical one. In this paper wederive the speed-flow relationship from more fundamental considerationsconcerning driving behaviour. We develop a structural model in which driverschoose...

This paper explores the interrelations between pricing, capacity choice and financingin transportation networks. It builds on the famous Mohring-Harwitz result on self-financing ofoptimally designed roads under optimal congestion pricing, and specifically investigates itsins and outs in a...

A dynamic 'car-following' extension of the conventional economic model of traffic congestion is presented, which predicts the average cost function for trips in stationary states to be significantly different from the conventional average cost function derived from the speed-flow function. When...

This paper considers second-best pricing as it arises through incomplete coverage of full networks. The main principles are first reviewed by considering the classic two-route problem and some extensions that have been studied more recently. In most of these studies the competing routes are...
