During the last two decades, economists have paid increasing attention
to the role of informal risk-sharing arrangements as a privileged way
through which traditional rural communities can achieve a significant
degree of protection against income fluctuations and other hazards be
yond their control. This article however argues that when they enter i
nto such arrangements members of these communities are guided by a pri
nciple of balanced reciprocity (they expect a return from any contribu
tion or payment they make) rather than by a true logic of mutual insur
ance. More precisely, they do not conceive of insurance as a game wher
e there are winners and losers and where income is redistributed betwe
en lucky and unlucky individuals. None the less, traditional agrarian
societies have proven able to develop a restricted range of sustainabl
e forms of mutual insurance that avoid the aforementioned problem.
