What's the evaluation of buffer stock schemes?

Buffer stock schemes (BSS) are economic policies aimed at stabilizing domestic prices in certain agricultural commodities by maintaining a strategic reserve of a particular commodity. Thepolicies involve governments buying up commodities whenever prices drop below the minimum support price, thus providing a floor for all commodities within their borders. Buffer stock schemes have had mixed success in providing price stability and improving market efficiency, as well as in reducing price volatility. Proponents of buffer stock schemes highlight the potential benefits that come with price stabilization and increased market efficiency, such as increased food security and reduced poverty through improved agricultural incomes. Meanwhile, critics point out that inefficiencies related to government intervention, such as over-priced commodities, result in a distorted market and create imbalances in supply and demand. Overall, the evaluation of buffer stock schemes is mixed, with some observations indicating potential benefits, while others pointing out inefficiencies and drawbacks. Ultimately, the success of such schemes depends upon the specific situation, commodity, and target population.
