■ 標題 The Panzar-Rosse Statistic Revisited |
■ 概要 In this note, we prove that even if the technology of firms exhibits increasing returns to scale, the Panzar-Rosse statistic in a monopolistic competitive market is still available and has a negative value. Further, we show that the statistic would be greater than unity if firms with increasing-returns-to-scale technology were to choose a saddle point under certain conditions. This implies that the value of greater than unity is not actually observed. Hiroshi Gunji and Yuan Yuan 共著 Theoretical Economics Letters 2017/01 |
