Optimal tax/subsidy intervention in commodity markets when the groups of interest are weighted unequally
研究了当政策制定者对不同利益群体赋予不同权重时，商品市场最优税收/补贴干预的条件，并识别了使社会福利函数与优化假设一致的权重、技术和偏好条件。
Models of optimal intervention in commodity markets often presume the existence of a policymaker who explicitly maximizes a social welfare function consisting of the weighted sum of welfare of different groups. This study identifies conditions regarding the weights attached to the groups of interest as well as the underlying technologies and preferences under which those welfare functions are consistent with the optimization hypothesis.
