Producer Surplus and Risk
研究风险规避下生产者行为的福利经济学，发现递减绝对风险规避时补偿变差小于马歇尔剩余，后者小于货币等价测度；常绝对风险规避时三者相等。
This paper examines the welfare economics of producer behavior under risk aversion. Hicksian, Marshallian, and money equivalent measures are explored. It is found that under decreasing absolute risk aversion, compensating variation is less than the ordinary Marshallian surplus, which is less than the money equivalent measure. Under constant absolute risk aversion all measures coincide. Finally, bounds on compensating and equivalent variations using ordinary producer surplus in a manner analogous to Willige approach in consumer theory under certainty are studied. Similar results hold, mutatis mutandis, for input demands.
