Valuation of Global IPOs: a Stochastic Frontier Approach

This paper studies the impact of global offerings on US IPO firms’ offer price using the stochastic frontier approach. We find that the offer price valuation efficiency for global IPOs exceeds that of IPOs with purely domestic offers by 3.1%. In particular, the global offering approach is most appropriate to those IPO firms, which offer larger proportion of new shares to international investors, underwritten by less prestigious investment banks and with larger firm-specific return variance. Our findings are consistent with the demand inelasticity, certification effect and investor recognition arguments that account for the benefits of global offering.
