On Optimal Enclosure and Optimal Timing of Enclosure.
This paper demonstrates that the enforcement of property rights by enclosing properties under common access is, in general, socially suboptimal: the timing of enclosure may be inappropriate, causing inefficiency. It is argued that the first fundamental theorem of welfare economics applies for a given collection of production sets, while enclosure implies a choice over collections of production sets.
