Samenvatting
Panel data are used to investigate what happens when people have some important transitions or change in their life- cycle, employment status, income, or car ownership. It is found that in many cases the effects on mobility are different from what would be expected from cross- section data. In particular:- car ownership changes are substantially less than expected;- public transport does not benefit as much as expected when people become members of specific dependent or"captive"groups.These results indicate that the effects of income growth on car ownership and therefore on public transport may not be as drastic as feared.
