Enterprise zones were first proposed by the Reagan administration as a supply-side effort to reenergize inner cities, and they were eventually embraced by liberals and conservatives alike. They are a compelling example of a policy idea that spread and evolved rapidly. Mossberger describes the information networks and decisionmaking processes in the five states, assessing whether enterprise zones spread opportunistically, as a mere fad, or whether well-informed deliberation preceded their adoption.
