| 摘 要： | 传统的新股发行定价偏低观点受到了一些定价偏高实证现象的质疑,且难以解释我国长期实行的发行市盈率管制政策。本文在原有信息不对称理论的基础上,从正向反馈的非理性角度研究发行定价,进而分析市盈率管制政策的作用,并实证检验。研究认为,新股发行市场中存在着大量的正向反馈申购者,他们受近期新股上市表现激发而参与申购,这种噪声需求的存在使得新股即使被高估也仍然能够成功发行。发行人和承销商意识到这种噪声需求的存在,为了使其利润最大化,他们会抬高发行定价,而机构投资者在近期新股上市表现较好的情况下也易于高估新股,因此也能接受较高的询价价格。实证结果验证了正向反馈申购者对发行定价的这一正向影响,并且发现市盈率管制政策能够对此起到一定的抑制作用。
