This paper presents an analysis of the perceptions held by for-hire and private trucking company logistics and operations managers about the impacts of congestion on their operations and the feasibility and effectiveness of actual and potential congestion mitigation policies. Responses to an extensive survey of nearly 1200 California-based or large national carriers are examined using confirmat...

The fast-pace development of trades with the Far East is giving the Mediterranean Sea the chance of becoming a major logistics hub. In the Mediterranean-front E.U. regions, public and private investments are aimed at this opportunity by integrating transportation networks, sea ports, and inland logistics platforms. With specific regard to North-Western Italy, a model based on System Dynamics ha...

To combat the environmental problems and congestion which arise from urban transportation, both end-of-pipe interventions such as traffic management and tailpipe emission control and more upstream measures such as urban and land-use planning have been implemented in many cities around the world. Singapore, in particular, has achieved rare success in managing congestion and the environment amid ...

The health system is a complex system of systems – changes in agriculture, transportation, economics, family life, medical practices, and many other things can have a profound influence on health and health costs. Yet today, policy-level investment decisions are frequently made by modeling individual systems in isolation. We describe two sets of issues that we face in trying to develop a platfo...

the demand for fossil fuel in the transport sector is constantly increasing and transportation is ranked amongst the highest greenhouse emitting sectors globally. today, tackling co2 emissions from road transport a widely discussed topic and constitutes a milestone towards reaching a sustainable, carbon neutral economy. this challenge is being described in various initiatives adopted in the eur...

Traffic congestion and the policies used to combat it have been studied extensively. One area which has received less attention is the secondary impacts of such policies. This paper uses a micro-simulation framework to study the effect on labour markets of road pricing. The key benefit of our chosen methodology is that it allows a simultaneous consideration of both commuting and migration decis...

The paper describes labor market developments for older workers in Germany in recent years. It provides a a summary of the main changes in labor market and pension policies in Germany which might have contributed to these developments.

Key findings in behavioral economics are that people’s behavior (revealed preferences) is often not in line with their intentions (normative preferences), that they are sensitive to the way choices are presented to them, and that their cognitive abilities are limited. This is manifest in particular in areas of intertemporal choice, like personal finance and health-related behavior. Policy maker...

In this paper, an incentive scheme based on crashing lead time is proposed to coordinate a supplier-retailer supply chain (SC). In the investigated SC, the supplier applies a lot-for-lot replenishment policy to replenish its stock and determines the replenishment multiplier. Moreover, the transportation lead time is considered under the control of the supplier. The retailer as downstream member...

We investigate the effects of fiscal policy surprises for US data, using vector autoregressions. We overcome the difficulties that changes in fiscal policy may manifest themselves in variables other than fiscal variables first and that fiscal variables may respond ”automatically” to business cycle conditions. We do so by using sign restrictions on the impulse responses as method of identificati...
