Why are certain property regimes preferred? They cannot be chosen on the ba
sis of efficiency considerations alone, as what is efficient depends on the
institutional structures themselves and the interests they defend. The aut
hor highlights some important distinctions between various property regimes
: whereas categories like private, common, and state property all may imply
some degree of co-ownership and overlap along some dimensions, the logic o
f each system, ideally defined, may be quite distinct. The author shows tha
t there is nothing inherent in a resource that demands a certain regime. Pr
operty regimes are social constructs and must be defended by judgment, not
by necessity. The author demonstrates that the main role of property regime
s is to defend certain interests. Furthermore, they seem to influence which
interests are formed or become activated. The preferences which form the b
asis for efficiency evaluations are thus dependent upon the chosen system.
In this way, technically oriented evaluations like cost-benefit analysis ar
e caught in severe circularities. The implication of this for policy is tha
t the evaluation of regimes implies taking a stand concerning what we want
to become, both as individuals and as a society.
