Compact or spread-out cities : urban planning, taxation, and the vulnerability to transportation shocks

Gusdorf F., Hallegatte S., 2007. Accepted by Energy Policy.

This paper shows that cities made more compact by transportation taxation are
more robust than spread-out cities to shocks in transportation costs. Such a shock,
indeed, entails negative transition effects that are caused by housing infrastructure
inertia and are magnified in low-density cities. Distortions due to a transportation
tax, however, have in absence of shock detrimental consequences that needs to be
accounted for. The range of beneficial tax levels can, therefore, be identified as a
function of the possible magnitude of future shocks in transportation costs. These
taxation levels, which can reach significant values, reduce city vulnerability and
prevent lock-ins in under-optimal situations.
