摘要

从业者如何模拟竞争影响合并的预期效果。我们展示了Bertrand价格设定和第二分数拍卖模型如何嵌套在一般议价框架内。通过数值模拟，我们展示了预测的合并效应如何随模型选择而变化，以及两种常用的获取需求参数的策略在不同的模型中会产生显著不同的结果。最后，我们展示了模型和校准策略选择如何影响2012年Bazaarvoice/PowerReviews合并的预测危害程度。

Consequences of model choice in predicting horizontal merger effects

How practitioners model competition influences the predicted effects of a merger. We show how a Bertrand price setting and a second score auction model can be nested within a general bargaining framework. Through numerical simulations, we then show how the predicted merger effects vary with model choice, and that two commonly used strategies for obtaining demand parameters can yield markedly different outcomes across the models. Finally, we show how model and calibration strategy choices affect the magnitude of predicted harm in the 2012 Bazaarvoice/PowerReviews merger.

期刊介绍： The IJIO is an international venture that aims at full coverage of theoretical and empirical questions in industrial organization. This includes classic questions of strategic behavior and market structure. The journal also seeks to publish articles dealing with technological change, internal organization of firms, regulation, antitrust and productivity analysis. We recognize the need to allow for diversity of perspectives and research styles in industrial organization and we encourage submissions in theoretical work, empirical work, and case studies. The journal will also occasionally publish symposia on topical issues.
