Dissecting preference heterogeneity in consumer stated choices This paper investigates alternative methods to account for preference heterogeneity in choice experiments. Heterogeneity can be explained by assuming its influence to impact the systematic component of utility, the stochastic one or both. Seven different models were estimated to search for heterogeneity along the three dimensions described. The [...]
Local public transport: service quality and tendering contracts Public transport is of extreme relevance for ensuring a sustainable modal distribution in urban areas across the globe (Hensher 2007). Local Public Transport (LPT) policies generally promote collective sustainable mobility in metropolitan areas encouraging travellers to give up mobility with their private vehicle. In recent times much attention has been placed on the [...]

Testing for nonlinearity in the choice of a freight transport service Manufacturing firms buy transport services with the aim of minimizing their total logistics cost. There is a large amount of literature analyzing how shippers value the various characteristics of a transport service, mostly performed by collecting stated-preference data and estimating discrete choice models. Most of [...]
Multi-level governance and transport policy: the case of local roads in Italy Italy is a multi-level polity where policymaking and implementation involves both public and private actors. Both territorial and functional decentralisation have an impact on the final results of policy making. In fact, territorial decentralisation implies the delegation of functions to wide multi-purpose tiers [...]
