Heterogeneity in urban freight policy impact: own-account agents in Rome’s LTZ, Working Paper SIET
No full textUrban freight policy-making aims to improve the efficiency of freight movement in cities.
Importantly, contemplated policies impact on complex pre-existent relationships among various
agents operating in the distribution chain. The most relevant operators to study are: retailers,
transport providers and own-account. There is a lack of knowledge concerning the specificities
of these agent-types behaviour that calls for a more detailed analysis at the agent-specific level.
This paper focuses on Urban Freight Transport (UFT) where an agent-specific policy analysis is
carried out with specific attention to own account agents. Own account is, in fact, among the least
studied agent-types in this context. This lack of attention is mainly due to the difficulty in
acquiring data concerning their preferences and also to the widely accepted presumption
concerning their relative inefficiency often giving rise to highly penalizing policies specifically
aimed at this group.
The empirical results reported are derived from a study conducted in the limited traffic zone
(LTZ) in Rome's city centre in 2009. The analysis is based on a highly detailed and representative
data set. This include both general information on the specific respondent involved along with
company characteristics as well as stated ranking exercises (SRE) where interviewees are
presented with alternative policy scenarios and asked to rank them according to their preference
structure. The paper reports on the specific preference structure for own account operators. The
paper proposes a systematic comparison, via WTP/WTA measures, between the potentially
inaccurate estimates deriving from a simplistic analysis of preferences and those originating from
an advanced treatment of preference heterogeneity. These considerations are prodromal to
potentially distorted policy forecasts that, in turn, would be fed into micro simulation models to
evaluate policy impacts.
Various forms of heterogeneity are explored. The data allow the analysis, among other socioeconomic
characteristics, of the impact that belonging to specific macro-freight-sectors has on the
attributes used in the SRE. Furthermore, adopting a latent class (LC) specification, we test for the
presence of respondent clusters in evaluating the policy mix considered for implementation.
The paper addresses methodologically innovative issues; uses a new, detailed and significant data
set; discusses a policy relevant issue and produces useful information from a policy-making
perspective. The quantification of WTP and WTA measures for possible policies to be
implemented provides an important benchmark both for policy makers as well as for researchers
in this sector

Heterogeneity in urban freight policy analysis: the case of own-account, retailers and transport providers in Rome’s LTZ

No full textItaly 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 8nal results of policy making. In fact, territorial decentralisation implies the
delegation of functions to wide multi-purpose tiers of sub-national governance, which has
been a central dynamic of Italian governance. Furthermore functional decentralisation
stresses the assignment of functions, vertically and horizontally, to single-purpose quasiautonomous
agencies. Multi level governance (MLG) aims at understanding the nature
and explaining the structure of governance networks, their inter-relationship with control,
capacity, accountability and e9ciency of political systems (Bache and Flinders, 2004 ; Piattoni,
2010 ). To date, only a limited use has been made of this important instrument of
analysis, at least in Italy, in transport policy, in general, and in the road sector, in particular.
Research in various domains such as political geography (Shaw et al., 2009), regional and
urban studies (Kern and Bulkeley, 2009) and institutional economics (Marsden et al., 2009)
have all stressed the crucial role governance plays in the transport sector notwithstanding
the lack of a common framework of analysis. The paper synthetically reports the de8nitions
of MLG proposed, describing their characteristics and clarifying their implications
for the transport sector, as well as discussing the implications of a speci8c MLG for the
transport sector regulatory system and for the role of local public authorities. Management
and programs of the local road sector in Italy are discussed with a particular focus on the
di:erent types of solutions adopted and to the impact on the level of integration among
di:erent governance levels. Finally a critical discussion of the situation of the local road
sector in Italy, its governability and some suggestions for the future are reported
