This paper systematically compares methods to build confidence intervals for willingness to pay measures in a discrete choice context. It contributes to the literature by including methods developed in other research fields. Monte Carlo simulations are used to assess the performance of all the...

Data quality plays a relevant role in policy evaluation. Data quality is also strictly linked to questionnaire development and administration strategies. Willingness to pay estimates might be influenced by the data acquisition method adopted if an ex-post sophisticated modelling cannot...

This paper jointly investigates non-linear attribute effects and discrete mixture heterogeneity. The research context relates to urban freight transport policy evaluation. The paper adopts an agent-specific perspective. The often unforeseen and undesired results deriving from urban freight...

Decision makers in urban freight transport (UFT) typically need to assess the impact new policy interventions might have on freight distribution. They need to assess the impacts of changes in freight distribution policies might have on a set of elements among which one can safely include:...

Urban freight distribution policies aim to improve the efficiency of deliveries of goods in cities. Local policy makers intervene on rooted, complex and pre-existent relationships. Various are the agents, both collaborating and competing, involved in providing and buying freight distribution...

This paper investigates alternative methods to account for preference heterogeneity in choice experiments. The main interest lies in assessing the different results obtainable when investigating heterogeneity in various ways. This comparison can be performed on the basis of model performance...

This paper reviews a set of articles, based on stated preferences techniques, focusing on logistics managers' preferences for freight transport attributes with the intent of assessing the quality of knowledge applied research has produced, its reliability and transferability. Transport choices...

In the last years Energy Efficiency (EE) has become an important issue in the public policy makers' agenda due to ambitious objectives of the European Commission to reduce energy consumption by 20% in 2020. Many countries have adopted state-level EE programs targeted to include Energy Saving...

The European Commission has recently developed a growing awareness with respect to the challenges urban freight transport (UFT) poses to cities and, consequently, has started defining specific policies and promoting dedicated tools to address them. Transport is a shared responsibility between...
