Inefficient targeting can increase inequality when higher producer prices or subsidised cereals are not received by the intended beneficiaries. Buffer stock programmes that pair producer price support objectives with the objective of providing lower prices to consumers often achieve only one goal at the expense of the other. Schemes that raise prices for producers frequently lead to higher consumer prices, which is in conflict with the food security objective of the scheme. When large amounts of grains are acquired to build or replenish public stocks, world supplies can be decreased and hence world market prices potentially increased.
