Abstract This note emphasizes some flaws of the Panzar–Rosse H statistic to address market power. First, I show that it is more related to the pass-through rate than to a market power measure, which implies reconsidering its interpretation and use. Second, I show that the inclusion of other strategic variables rather than prices or quantities may lead to contradictory predictions about market power. Therefore, competition authorities should refrain from using the H statistic to rule out significant market power because it is not a well-behaved measure of the degree of competition.

Panzar-Rosse H 统计和垄断。将其用作市场力量衡量标准的问题

摘要 本说明强调了 Panzar-Rosse H 统计量在处理市场支配力方面的一些缺陷。首先，我表明它与传递率的相关性比与市场支配力度量的相关性更大，这意味着重新考虑其解释和使用。其次，我表明，包含其他战略变量而不是价格或数量可能会导致对市场力量的相互矛盾的预测。因此，竞争主管部门应避免使用 H 统计量来排除显着的市场支配力，因为它不是衡量竞争程度的良好衡量标准。
