This essay attempts to clarify and simplify the results of the literature on price stabilization in order to provide a better sense of the conditions under which commodity stabilization schemes will be successful and the welfare effects of such schemes. After introducing the early framework under which price stabilization was analyzed, the paper demonstrates the variance of results under alternative and more realistic situations. It treats topics such as storage and food security, inflation and economic development, public storage and futures markets, and non-storable goods. The conclusions are: (i) some countries may lose from price stabilization even though there is a net global gain; (ii) liberalized trade reduces the need for buffer stocks; (iii) futures markets reduce instability at a lower cost than buffer stocks; (iv) many national price stabilization schemes are actually price support systems used to improve farmers' incomes; (v) good price forecasting is a prerequisite to well-managed buffer stocks; (vi) price stability in poorer countries is not sufficient to avoid occasional food shortages; and (vii) food is costly to store and may not alleviate famine if transportation and distribution systems are inadequate.
