M. TIVADAR: “It is better to live in a US or a European City?”, Regional Science and
Urban Economics 40 (2010) 221–227
We examine equilibria for a city where amenities are generated and valued by a social group,
the rich. We considered two types of spatial structures: the American equilibrium (where rich
households are located at the periphery) and the European equilibrium (where the rich
households are concentrated in the central part of the city), proving that both can exist, and
deriving their conditions. We find that the European equilibrium is more restrictive than the
American one. The second main result is that, in terms of welfare, the American structure is
superior to the European one.
M. TIVADAR and H. JAYET: “Endogenous amenities and spatial structure of cities”
(working paper, to send to Journal of Regional Science and Urban Economics)
We examine the dynamics of urban social structures when spatial distribution of amenities is
endogenously modified by the location pattern of social groups. At each period, the
equilibrium urban structure is determined by the distribution of amenities; but, between
periods, this distribution changes, rich households generating local amenities in the locations
they occupy, and therefore the social structure of the city changes. We show that when local
amenities are endogenously generated, as the city develops, it passes from an American urban
structure (rich located to the periphery) to a European one (central localisation of rich).
M. TIVADAR and H. JAYET: “Second best congestion tolls and city spatial structure”
(working paper)
The main objective of this paper is to study the link between the urban economic fundamentals
(the households’ demand for land, the nature and the importance of the objective and
subjective transportation costs), the urban structures and the ecological impact of the city,
leading to an analysis of the role of the public authority and urban policies. This paper
considers second-best congestion pricing in a discrete monocentric city with two income
social classes. Four tolls schemes are analyzed: area charges (or downtown parking fee), flat
kilometre toll and cordon charging with two possible locations of the cordon. The numerical
simulations show that all these schemes have a significant impact on city’s structure, but
global tolls (area charges and flat toll) present better results economically and ecologically
than the partial tolls (cordon charging).
M TIVADAR, N. BERTRAND, T. RAMBONILAZA : “Aged population settlement patterns
within the process of peri-urbanisation : a residential location choice perspective analysis
with French data” (working paper)
The objective of this work is to capture the impact of demographic changes on housing
demand and urban-periurban-rural relationships, with application on Département de
l’Hérault (South of France). For that, we analyze residential choice in using a nested logit
model: the households are choosing their location in two stages, as a trade-off mainly
between urban services and natural amenities. In the first stage, they are choosing one of the
three macro-zones of the area, which corresponds to the zone of influence of the most
important municipalities: Montpellier, Béziers and Sète. Then, inside each macro-zone, the
households are choosing one of several spatial units, which are the result of spatial
aggregation of municipalities by geographical, economic and social criteria. Based on
several scenarios on population evolution, we will use the estimated model to forecast
housing demand in the area.
M TIVADAR: “Commuting Modelling and Urban Transportation Policies: Application for
Lens Area” (working paper)
The objective of this work is to study the commuting in Lens area (France), and analyzing the
role of urban transportation policies. The model is designed in three loops: the first is the
location loop where households make their residential choice. The second is the commuting
loop, where they make a modal choice for between public and private transportation. The last
is the pollution loop, which is the result of the first two and influences the attractiveness of the
area. This model allows us to simulate the impact of different transportation policies as tools
to avoid road congestion and automobile pollution: a new tram line with independent
infrastructure and other complementary policies.
M TIVADAR, C. TARTIU: “Hotelling applied in tourism economics ” (working paper)
In this paper, we use Hotelling representation as an alternative to Lancaster approach, which
is commonly used to analyse tourism demand and destination choice. The results are
comparable with the standard models, but more realistic. If in a Lancaster framework the
tourism demand for each destination is continuous on prices, in our model it is influenced in a
discrete manner: for certain threshold price levels, the tourist choice could be oriented to a
mono-destination or a multi-destination holiday. We obtained thresholds prices which allow a
destination to attract completely or partially the consumer, depending on the price practiced
by the concurrent destination.
