行为选择模型产生的不平等，当与其他假设相结合时，可以用作估计的基础。本文考虑了两组此类假设，并在两个经验示例中使用它们。第二个例子考察了垂直市场中上游互动产生的支付结构。然后，我们在一个数值分析中模拟这个例子的经验设置，计算实际的均衡，研究它们的特征如何随市场环境而变化，并将它们与经验结果进行比较。最后一节使用的数值结果在蒙特卡洛分析的鲁棒性的两种方法来估计其基本假设。
Behavioral choice models generate inequalities which, when combined with additional assumptions, can be used as a basis for estimation. This paper considers two sets of such assumptions and uses them in two empirical examples. The second example examines the structure of payments resulting from the upstream interactions in a vertical market. We then mimic the empirical setting for this example in a numerical analysis which computes actual equilibria, examines how their characteristics vary with the market setting, and compares them to the empirical results. The final section uses the numerical results in a Monte Carlo analysis of the robustness of the two approaches to estimation to their underlying assumptions.
