Résumé / Abstract
This paper revisits the elasticities of car traffic using panel data set of the 21 french regions over the period 1973-1999 considering spatial interdependences. Two spatial specifications including random or fixed effects are retained. These models have been estimated using the Maximum Likelihood estimator (MLE) according to iterative two-stage procedures. We find that significant spatial interdependences characterize the regional car traffic per vehicle. Following the spatial specifications, the price of motor gasoline elasticities fall in the range −0.14 to −0.08. The other elasticities vary respectively from 0.30 to 0.57 for household income per capita, and from −0.54 to −0.28 for car fleet per capita, confirming that there are more and more cars, but that each of them are less and less used.
