Similarly, Perrings defines possession rigorously. "The commitment of positively valued resources to the exaction of environ- mental resources implies that the latter are possessed and so endowed with value. Proprietary rights in a process are, by contrast, necessary but not sufficient to ensure that the outputs of that process are positively valued... The possession of a resource implies that it is incorporated in a particular property and, hence, value system..." He analyses the multiplicity of value systems that have existed historically by drawing upon anthropological literature. The results of this analysis will be of value to development economists and policymakers. It would be interesting to compare and contrast Perrings' results in, say, the context of urban informal markets, as analysed by, for example, N Vijay Jaganathan in Informal Markers in Developing Countries, (OUP, 1987).
