Reconciling the von Liebig and Differentiable Crop Production Functions
通过将异质性投入对线性响应与平台模型的影响加总，推导出平滑可微的生产函数，并用玉米生长数据检验两种具体加总方式。
Abstract Two commonly used forms for crop response to inputs are a smooth, differentiable production function and a linear response and plateau (LRP) model. This paper reconciles these two views by showing that smooth functions can be derived by aggregating the effects of heterogenous inputs on LRP functions. Data on corn growth are used to test two specific aggregations.
