Although all advanced industrial societies have urban and regional development policies, such policy in the United States historically has taken on a very distinct form. Compared with the more top-down, centrally orchestrated approaches of Western European countries, US cities and, to a lesser degree, states, take the lead, spurred on by developers and those with interest in rent. This bottom-up policy creates conflict as one city battles with another for new investments and as
real estate developers fight over the spoils, resulting in highly contentious politics.
