Across the globe policy makers implement, and academics teach and undertake research upon, place-based policy. But what is place-based policy, what does it aspire to achieve, what are the benefits of place-based approaches relative to other forms of policy, and what are the key determinants of success for this type of government intervention? This Policy Expo examines these questions, reviewing the literature and the experience of places and their governments around the world. We find place-based policies are essential in contemporary economies, providing solutions to otherwise intractable challenges such as the long-term decline of cities and regions. For those working in public sector agencies the success or failure of place-based policies is largely attributable to governance arrangements, but for researchers the community that is the subject of this policy effort, and its leadership, determines outcomes. This Policy Expo explores the differing perspectives on place-based policy and maps out the essential components of effective and impactful actions by government at the scale of individual places.
