Even though land-use convenants are a pervasive feature in residential
land markets, they are typically subsumed into the economist's pictur
e of zoning and related land-use regulation. In contrast to the tradit
ional approach, the premise of this study is that land covenants diffe
r from zoning in important respects. This study examines the character
istics of covenants as an institution and why it exists as a distinct
method of private control in land markets. The approach taken here emp
hasizes the role of credible commitment in explaining why covenants di
ffer from both zoning and private contracts among individuals. The pap
er also examines why covenants tend to vary spatially within urban are
as, presenting two theories to evaluate the evidence from an urban hou
sing market.
