本文概述了最近开发的技术，估计所需的实证分析均衡的相互作用和它们的影响，在寡头垄断市场的原语。它分为一个介绍和三个部分;一个关于估计需求函数的部分，一个关于估计生产函数的部分，一个关于估计“动态”参数的部分（通过它们对决定未来利润分配的控制选择的影响来估计的参数）。应用程序，并解释了各个部分的结构。这三个部分的主题在以前的文献中都有涉及。因此，每一节都以审查问题I. O开始。研究人员在使用以前的方法时遇到的问题。然后，这些部分继续对最近的技术及其与先前方法的问题的关系进行了相当详细的解释。希望细节足够丰富，使读者能够实际编程一个版本的技术，并使用它们来分析数据。在每一节的结尾，我们简要讨论了一些与最新技术有关的问题。这里的重点是在什么时候这些问题可能特别重要，以及最近的研究旨在克服他们时，他们。
This paper outlines recently developed techniques for estimating the primitives needed to empirically analyze equilibrium interactions and their implications in oligopolistic markets. It is divided into an introduction and three sections; a section on estimating demand functions, a section on estimating production functions, and a section on estimating "dynamic" parameters (parameters estimated through their implications on the choice of controls which determine the distribution of future profits).The introduction provides an overview of how these primitives are used in typical I.O. applications, and explains how the individual sections are structured. The topics of the three sections have all been addressed in prior literature. Consequently each section begins with a review of the problems I.O. researchers encountered in using the prior approaches. The sections then continue with a fairly detailed explanation of the recent techniques and their relationship to the problems with the prior approaches. Hopefully the detail is rich enough to enable the reader to actually program up a version of the techniques and use them to analyze data. We conclude each section with a brief discussion of some of the problems with the more recent techniques. Here the emphasis is on when those problems are likely to be particularly important, and on recent research designed to overcome them when they are.
