Abstract This paper documents some thoughts on the reform agenda in public transit that is occurring throughout the world. The specific focus is on a growing commitment to competitive regulation through competitive tendering, and the efforts by a few governments (notably in Australia) to take control of the tangible assets used by private operators as a mechanism to exercise the opportunity, if so taken, to put services out to competitive tender. The paper reviews the theoretical arguments and empirical evidence on contracting regimes and asset ownership, and the role that government and the operator might play in a setting in which building trusting and collaborative partnerships has merit in delivering services that are in the main funded from the public purse. 相似文献

It is widely recognized that individual decision-making is subject to the evaluation of gains and losses around a reference
point. The estimation of discrete choice models increasingly use data from stated choice experiments which are pivoted around
a reference alternative. However, to date, the specification of a reference alternative in transport studies has been fixed,
whereas it is common to observe individuals adjusting their preferences according to a change in their reference point. This
paper focuses on individual reactions, in a freight choice context, to a negative change in the reference alternative values,
identifying the behavioural implications in terms of loss aversion and diminishing sensitivity. The results show a significant
adjustment in the valuation of gains and losses around a shifted reference alternative. In particular, we find an average
increase in loss aversion for cost and time attributes, and a substantial decrease for punctuality. These findings are translated
to significant differences in the willingness to pay and willingness to accept measures, providing supporting evidence of
respondents’ behavioural reaction. 相似文献

The intermodal logistics supply chain is designed to move goods from the point of production to the point of consumption as quickly and as cheaply as possible. The ability to accomplish this objective has allowed for the wholesale geographic relocation and offshoring of basic manufacturing and assembly. As a chain of linked and integrated organizations characterized by sequential interdependence, interorganizational relations play a key role in determining the level of integration and seamlessness. Yet there is one critical interorganizational link in the chain that deviates from this vision. This is the relationship between the shipping container terminal and drayage trucking operations which is better described as a form of intermodal disintegration. The weakness in this link of the supply chain is explained by the divergent industrial structures and labor market conditions, the unique nature of the transaction, and the externalization of costs to subordinate workers. 相似文献

Interest in alternative behavioural paradigms to random utility maximization (RUM) has existed ever since the dominance of the RUM formulation. One alternative is known as random regret minimization (RRM), which suggests that when choosing between alternatives, decision makers aim to minimize anticipated regret. Although the idea of regret is not new, its incorporation into the same discrete choice framework of RUM is very recent. This paper is the first to apply the RRM‐model framework to model choice amongst durable goods. Specifically, we estimate and compare the RRM and RUM models in a stated choice context of choosing amongst vehicles fuelled with petrol, diesel and hybrid (associated with specific levels of fuel efficiency and engine capacity). The RRM model is found to achieve a marginally better fit (using a non‐nested test of differences) than its equally parsimonious RUM counterpart. As a second contribution, we derive a formulation for regret‐based elasticities and compare utility‐based and regret‐based elasticities in the context of stated vehicle type choices. We find that in the context of our choice data, mean estimates of elasticities are different for many of the attributes and alternatives. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

The appropriate interpretation of a behavioural outcome requires allowing for risk attitude and belief of an individual, in addition to identification of preferences. This paper develops an Attribute-Specific Extended Rank-Dependent Utility Theory model to better understand choice behaviour in the presence of travel time variability, in which these three important components of choice are empirically addressed. This framework is more behaviourally appealing for travel time and travel time variability research than the traditional approach in which risk attitude and belief are overlooked. This model also reveals significant unobserved between-individual heterogeneity in preferences, risk attitudes and beliefs. 相似文献

This paper investigates the factors that influence the choice of, and hence demand for taxis services, a relatively neglected mode in the urban travel task. Given the importance of positioning preferences for taxi services within the broader set of modal options, we develop a modal choice model for all available modes of transport for trips undertaken by individuals or groups of individuals in a number of market segments. A sample of recent trips in Melbourne in 2012 was used to develop segment-specific mode choice models to obtain direct (and cross) elasticities of interest for cost and service level attributes. Given the nonlinear functional form of the way attributes of interest are included in the modal choice models, a simple set of mean elasticity estimates are not behaviourally meaningful; hence a decision support system is developed to enable the calculation of mean elasticity estimates under specific future service and pricing levels. Some specific direct elasticity estimates are provided as the basis of illustrating the magnitudes of elasticity estimates under likely policy settings. 相似文献
