论文摘要
当将收入用作输出代理时，生产功能可能会误指出。我通过表明生产功能和希克斯中立的生产力都无法通过这样的收入代理来形式化并增强这种常识。在放松文献中使用的标准假设以允许竞争不完善时，该结果将获得。它具有大量生产功能，包括所有常用的参数形式。在解决此问题的普遍方法中，只有那些对基础需求系统施加假设的方法可以识别生产功能。
Production functions are potentially misspecified when revenue is used as a proxy for output. I formalize and strengthen this common knowledge by showing that neither the production function nor Hicks-neutral productivity can be identified with such a revenue proxy. This result obtains when relaxing the standard assumptions used in the literature to allow for imperfect competition. It holds for a large class of production functions, including all commonly used parametric forms. Among the prevalent approaches to address this issue, only those that impose assumptions on the underlying demand system can possibly identify the production function.
