Seasoned Offerings, Imitation Costs, and the Underpricing of Initial Public Offerings


  • Welch, Ivo


The author presents a signaling model in which high-quality firms underprice at the initial public offering in order to obtain a higher price at a seasoned offering. The main assumption is that low-quality firms must invest in imitation expenses to appear to be high-quality firms, and that with some probability this imitation is discovered between offerings. Underpricing by high-quality firms at the initial public offering then adds sufficient signaling costs to these imitation expenses to induce low-quality firms to reveal their quality voluntarily. In addition, the paper provides empirical evidence that many firms raise substantial amounts of additional equity capital after their initial public offering.
