Joint pricing and design of urban highways with spatial and user group heterogeneity 总被引:1,自引:1,他引:0
This paper addresses the joint optimization of capacity investments and toll charges imposed on multi-group users in monopolistic
private highways within general road networks. A game-theoretic formulation is provided that leads to a nonconvex bilevel
program. The proposed modeling framework handles several complex issues raised in realistic applications, such as regulations
on the levels of tolls and service, and the discrete nature of highway capacity, using a genetic optimization technique. Real-application
results show the importance of considering the spatial heterogeneity of prices, and the tradeoff between investments and pricing
strategies in regulated private highways. 相似文献

The economic development features for the decades after the Second World War provide evidence that investments to new infrastructures are a key driver in strengthening the national economy and enhancing nation’s productivity, as it creates economic benefits and additional income. However, the decision for fund allocation and investments in mega infrastructure pipeline projects often must be made in conditions that are much more fraught with uncertainty. The key question in such decisions is if the economic impact caused by the new project could be able to essentially boost the economy by creating new jobs and generating new income on one hand; and which are the business sectors expected to archive the benefits of this investment. This article deals with the estimation of the mega infrastructure pipeline project economic effects in economy. The methodological framework is based on input–output approach providing quantitative estimations about the economic impact of the project in terms of new income and jobs. The numerical application deals with the assessment of a cross-border crude oil pipeline project, connecting the ports of Burgas (Bulgaria) and Alexandroupolis (Greece), establishing a new transportation corridor for the crude oil from Black Sea to Southeast Mediterranean. 相似文献

The paper demonstrates that the standard neoclassical model of stochastic growth in the absence of any other modifications is consistent with club convergence contrary to the analysis in Cetorelli (2002, Journal of Economic Dynamics and Control, 27, pp. 29–50). In that sense, it is not necessary to augment the model with a probability of adverse shocks that is inversely related to aggregate capital stock or provide other modifications. 相似文献

Evolutionary game-theoretic model for dynamic congestion pricing in multi-class traffic networks 总被引:1,自引:1,他引:0
This paper describes an evolutionary game-theoretic learning model for dynamic congestion pricing in urban road networks,
taking into account route choice stochasticity and reliability considerations, and the heterogeneity of users, in terms of
their value of travel time and real-time information acquisition. The learning model represents the dynamic adjustments of
users to travel cost changes which may take place in the day-to-day as well as the within-day timescales. The implementation
into a simplified and a real urban road network signifies the important implications of modeling the dynamic and stochastic
learning components of users’ behavior for accommodating the efficient deployment of congestion pricing schemes. 相似文献

Road accidents have a major impact on the economy as well as society. In other words, such an event also has an impact on the affected individuals’ contribution back to society and state. The purpose of this paper is to study the effect of traffic accidents on the economy. We evaluate the value or cost of a human life in traffic accidents. To estimate the cost, we need to know the income contribution of each individual via his or her employment or other earnings, i.e. his or her income-generating capacity for the remainder of his or her life, had the incident not occurred. Then we find the “present value” of such income, adjusted for the probability of such an event (fatality) happening. This is similar to the calculation of a pure insurance premium. Assessment of the economic impact caused by human life loss is dealt with using insurance-based methods. We calculate the burning cost of an insurance policy that provides coverage for the risk under investigation. It is of interest to the state and the family of the deceased to recover as much of this lost income as possible. 相似文献

The purpose of this article is to examine the issues related to the chewing gum marketing practices employed by a Cypriot company importing gum. Thus, the product, its target market, and competition are examined, a SWOT analysis is performed and the marketing mix is presented. Then the results are compared with the international market. The case study method was employed to gain an initial understanding of the marketing practices employed by the company concerning the production of chewing gum. The findings showed that the company offers a gum of superior quality, which in two years' time has captured a great share of a very competitive market. The company is giving special attention to the distribution and the promotion of the product. 相似文献

This paper presents experimental evidence from a simple three-person game showing that many individuals are willing to avenge third-party punishment in one-shot interactions. The threat of counter-punishment has a large negative effect on the willingness of third parties to punish selfish behavior. In spite of this, the extent of selfish behavior is identical to that in a treatment without counter-punishment opportunities. We discuss explanations for this puzzling finding. 相似文献

This paper argues that judgement on the wider claims of systems planning should be suspended until a fuller evaluation has been completed. As part of this evaluation, it is argued that the relation between the activities of politics and of planning will remain ambivalent so long as the two concepts retain their elastic definitions. In this context this paper examines the British literature on systems planning and concludes that conflicts generated in the formulation of goals cannot be imploded, from the political arena into planning and resolved there through the application of deductive logic. It is argued that goal formulation needs to be reconceived as an activity where the deductive logic of systems planning and the interactive logic of politics interpenetrate and permeate each other. It is argued that neither is it desirable that deductive logic should dominate political activity, nor is it feasible that the interactive logic of politics should dominate the activity of planning.Interpenetration may be seen in the activity of representation, where although the represented are capable of acting, their representatives act for them (not instead of them) in other arenas. It is argued that ultimately, though politics is a logically prior activity and though planning is instrumental, they need to be conceived as interdependent but semi-autonomous activities, linked by the process of formulating desirable goals which are also feasible. 相似文献

We study the willingness to compete of 588 children and teenagers aged ten to seventeen. We replicate the gender difference in tournament entry choices usually found in the literature for adults. We then show that policy interventions like quotas and preferential treatment help to close down the gender gap without leading to losses in efficiency, during or after a tournament. Given that differences in competitive behavior are prevalent from an early age, the application of interventions to promote females in competitions may be desirable already at early ages to promote equal chances for women on labor markets later on. 相似文献
