The Panzar-Rosse test has been widely applied to assess competitive conduct, often in specifications controlling for firm scale or using a price equation. We show that neither a price equation nor a scaled revenue function yields a valid measure for competitive conduct. Moreover, even an...

The Panzar-Rosse model is a widely applied method to assess competitive conduct. In particular, it has been extensively used to analyze the competitive climate in the banking industry. To correct for differences in firm size, many empirical papers estimate a Panzar-Rosse revenue function with...
