Does ownership structure effect IPO underpricing: Evidence from Thai IPOs

Abstract

The study utilizes a unique set of IPOs data in Thailand post Asian Financial crises to identify the relationship between initial market adjusted underpricing and the ownership concentration. We find that a weak but a negative relationship exists between the two and therefore to certain extent refuting the signaling hypothesis of high ownership and high underpricing. We employ a rank correlation to identify the association between the two variables. A regression model using the widely used proxies of information asymmetry model fails to up hold the information asymmetry model in the context of Thai IPOs
