| Abstract: | This paper focuses on residential sorting by social and ethnic status in large 
French urban areas. Our objective is to assess the relative importance of two 
major determinants of segregation stressed by the economic literature 
(Bartolome and Ross, 2003 ; Brueckner et al., 1999) : (i) "Alonso sorting over 
space", due to the trade-off between land consumption and accessibility to the 
central city and (ii) "Tiebout sorting over jurisdictions", due to the taste 
for local public goods and by extension for all kinds of local public 
amenities (e.g. neighborhood externalities). Our methodology draws on 
Schmidheiny (2006). First, a conditional logit model is estimated for each 
urban area, in which moving households are assumed to sort based on 
jurisdiction distance to the central city and jurisdiction mean of households' 
incomes (as a proxy for the level of public amenities). Second, our estimation 
results are used to simulate the counterfactual residential patterns that 
would prevail if, alternatively, one or the other of these mechanisms were 
inactive (setting the coefficients of the corresponding variables to zero). 
The contribution of each mechanism to the observed social and ethnic 
segregation is finally appreciated by comparing the values of dissimilarity 
indexes computed on the basis of the counterfactual households distributions 
and on the observed households distribution. "Tiebout-sorting" emerges as the 
primary cause of social segregation among wage-earning households. On the 
contrary, "Alonso-sorting" appears to be the main driver of segregation 
between economically active and inactive households, as well as between 
Frenchcitizen and Foreign-citizen households. |
