With urban planning policy in transition in many parts of the world, t
he need to understand the theoretical bases for planning and to ground
discussion about policy innovations on theory is as important as ever
, This essay reviews the relevance of three economic paradigms to the
theory of development control, It is written as a technical review wit
h the purpose of explaining, contrasting and contextualising the contr
ibutions of these paradigms, Much has been written about the Pigouvian
case for regulative planning, The Coasian literature is strong especi
ally in the US but is not so well known elsewhere; and little has been
written that draws together the diverse perspectives offered by the p
ublic choice school, This essay has been written particularly for acad
emic planners and urban social scientists in the UK, and in other Euro
pean and Commonwealth countries who are not familiar with the technica
l arguments underlying the Cease vs Pigou zoning debate, It is also an
essay on the public choice theory of planning since it contextualises
Coasian planning theory within that wider critique of welfare economi
cs, Among other points, it argues that the relevance of Coasian planni
ng theory is not by any means restricted to US-style zoning, nor is it
purely a debate about deregulation Coasian and other public choice pe
rspectives generate a rich source of theoretical and empirical proposi
tions which should be tested and developed, particularly as frameworks
for comparative analysis of planning constitutions and policies, In t
his spirit, the essay concludes with elements of a research agenda.
