One of the problems of focussing on size of group as a key determining factor is that many other variables change as group size increases (Chamberlin 1974; R.
Hardin 1982). If the costs of providing a public good related to the use of a forest, say a sanctioning system, remain relatively constant as group size increases, then increasing the number of participants brings additional resources that could be drawn upon to provide the benefit enjoyed by all (see Isaac et al. 1993). Marwell and
Oliver (1993: 45) conclude that when a good has pure jointness of supply, group size has a positive effect on the probability that it will be provided. On the other hand, if one is analysing the conflict levels over a subtractable good and the transaction costs of arriving at acceptable allocation formulae, group size may well exacerbate the problems of self-governing systems.
Since there are tradeoffs among various impacts of size on other variables, a better working hypothesis is that medium-sized groups may succeed more often than very small or very large groups.
