Government intervention in the market is a fact of life. Examples of social
policy that affect land value include zoning, rent control, design constraints,
environmental restrictions, historic overlays, to name only a few.
A capable developer must be able
to model the cost-benefit analysis of various government proposals or restrictions
in order to educate policymakers about the long run consequences of their
actions. In the graphic to the left the developer faces an aesthetic regulation
in the form of a sign ordinance that proposes to reduce the effectiveness
(g) commercial advertising by restricting the size and height of outdoor
signs. He knows that the community must choose how to allocate its scare
resources (tax revenue) between providing “hard” benefits such
as police and fire protection and enforcing “soft” benefits
such as aesthetic regulation.
The restriction on advertising has secondary consequences that affect tax
collections. The aggregation of the costs and benefits produce community
satisfaction in the form of “utility”. The developer models
an optimal amount of advertising (A*), given the constraints in place and
shows how the community will suffer lost satisfaction by moving to a more
restrictive level of advertising.
