What should be the distribution of the benefits of a fishery (or commo
n-pool resource) where a group of fishers catch fish and sell it to co
nsumers? I propose that, for each person i, where i is a fisher or a c
onsumer, i's returns should be proportional to i's contributions. Unex
pectedly, this implies that the fraction of benefits accruing to consu
mers must be root value of total output of fish/root value of total ou
tputs of fish + root value of total fisheres' labor.
