模拟实验证明了Panzar-Rosse，霍尔和结构方法来估计或测试市场势力的优点和缺点。结构模型只有在正确指定时才能正常工作。霍尔方法适用于具有恒定规模报酬率（CRS）的行业;然而，即使是与CRS的微小偏差也会导致严重的偏差。尽管比结构性方法更容易使用，但Panzar-Rosse方法无法区分某些技术的共谋和竞争。霍尔和Panzar-Rosse方法的一些经验应用。
Simulation experiments demonstrate the strengths and weaknesses of the Panzar-Rosse, Hall, and structural approaches to estimating or testing market power. The structural model works well only if it is properly specified. The Hall methods works well in industries with constant retums to scale (CRS); however, even slight deviations from CRS lead to serious biases. Although easier to use than the structural approach, the Panzar-Rosse approach cannot distinguish between collusion and competition for some technologies. Some empirical applications of the Hall and Panzar-Rosse methods are provided.
