This paper explores interrelations between pricing, capacity choice, and financing in transportation networks. We build on the Mohring-Harwitz result on self-financing of optimally designed and priced roads and investigate it in a network environment under various types of second-best regulation. A small network model with endogenous car ownership demonstrates that optimal congestion pricing an...

In this paper, the fixed charge solid transportation problem under uncertainty is investigated. As a result, three mathematical models are constructed for the problem, i.e., expected value model, chanceconstrained programming model and measure-chance programming model, where the supplies, demands, conveyance capacities, direct costs and fixed charges are regarded as uncertain variables. After t...

The fixed-charge transportation problem is an interesting problem in its own right. This paper further motivates its study by showing that it is both a special case and a strong relaxation of the big-bucket multi-item lot-sizing problem. We then provide a polyhedral analysis of the polynomially solvable special case in which the associated bipartite graph is a path. We give a O(n 3)-time optimi...

The purpose of the study was to examine whether poor working conditions influenced drivers' psychological health, and to identify drivers' personality characteristics. The subjects were 208 bus drivers working in the European sector in Istanbul. Their personality characteristics, psychological symptoms and anxiety levels were investigated using the Eysenck Personality Questionnaire (EPQ), the S...

a r t i c l e i n f o JEL classification: L13 L2 L93 Keywords: Short-haul routes Long-haul routes Flight frequency Distance This paper presents a theoretical and empirical analysis of the relationship between frequency of scheduled transportation services and their substitutability with personal transportation (using distance as a proxy). We study the interaction between a monopoly firm providi...

We know that human neurocognitive systems rapidly and implicitly evaluate emotionally charged stimuli. But what about more everyday, frequently encountered kinds of objects, such as computer desktop icons and business logos? Do we rapidly and implicitly evaluate these more prosaic visual images, attitude objects that might only engender a mild sense of liking or disliking, if at all? To address...

The charge F 1 (0) and the magnetic F 2 (0) form factors of heavy charged leptons have been shown in the framework of the perturbation theory to have imaginary part. The imaginary parts of the form factors for muon and tau lepton have been calculated at the two-loop level in the Standard Model. The effects where these imaginary parts could manifest themselves are discussed.
