The theoretical structure of producer willingness to pay estimates
分析生产者对新投入品支付意愿的理论基础，推导其比较静态性质，并展示如何用这些性质估计需求或供给数量及价格弹性。
This article analyzes the theoretical underpinnings of producer willingness to pay (WTP) for new inputs. In addition to conceptualizing the producer WTP function, we derive its comparative statics and show how these properties can be used to estimate quantities demanded or supplied and price elasticities. We also discuss implications of the comparative statics.
