The literature on noncompliant firms in transferable emissions permit syste
ms offers little guidance to policymakers that must determine how to commit
resources to monitor firms and punish violations in such systems. We consi
der how a budget-constrained enforcement authority that seeks to minimize a
ggregate noncompliance in a transferable emissions permit system should all
ocate its monitoring and enforcement efforts among heterogeneous firms. Wit
h a conventional model of firm behavior in a transferable permit system, we
find that differences in the allocation of monitoring and enforcement effo
rt between any two types of firms should be independent of differences in t
heir exogenous characteristics. (C) 1999 Academic Press.
