Can self-selection of subsidized commodities be used as a mechanism to
transfer income to the poor? Evidence from two self-targeting program
s, one in South Africa and one in Tunisia, shows that although self-ta
rgeting can clearly improve the distribution of food subsidies to the
poorest members of society, its power to alleviate poverty and reduce
income disparities is limited by preference patterns, income inequalit
y, and the size of the individual subsidies. Self-targeting through qu
ality and product differentiation can be a useful means to reform exis
ting universal subsidy schemes, but it should be considered a transiti
onal tool while the capacity for implementing more precise mechanisms
is developed.
