'Pure' and 'impure' Coasian solutions in planning

There has been a recent increase in the application of the Coase Theorem to planning. The principal objective of this article is to explore further the role of such solutions by setting out our interpretation of the conditions necessary for the achievement of 'Pure' and 'Impure' Coasian solutions when legal entitlements and property rights are established in a planning context. It explores the potential of negotiated solutions in relation to development control and as a theoretical basis for community gain. Finally, it outlines a number of case studies examining whether 'Impure' Coasian solutions have delivered community gain through directly and indirectly moderated negotiations.
