Exact Welfare Measurement for Producers under Uncertainty
证明，在价格或生产不确定性下，生产者的事前补偿变差和等价变差可从通常的事前产出供给或投入需求函数获得，无需假设决策者的风险厌恶，并推导了参数变化的精确福利度量表达式。
Abstract Ex ante compensating and equivalent variations for producers under price or production uncertainty frequently can be obtained from properly specified ordinary ex ante output supply or input demand functions without assumptions about the decision maker's risk aversion. The Slutsky‐Hicks equations for several common empirical specifications of the production problem under uncertainty can be integrated to obtain the compensated supplies (demands) from observed ordinary supplies (demands). Closed‐form expressions for the exact welfare measures of parameter changes are derived for these cases.
