Recent literature has been largely negative in its assessment of corporate diversification. Diversified firms have been regarded as destructive of firm value, prone to agency problems and divisional rent-seeking. The empirical finding that multi-division firms tend to trade at a 'discount,' or...

Our model of the initial public offering process links the three main empirical IPO anomalies underpricing, hot issue markets, and long-run under performance and traces them to a common source of inefficiency. We relate hot IPO markets (such as the 1999/2000market for Internet IPOs) to the...

We model an IPO company's optimal response to the presence of sentiment investors and short sale constraints. Given regulatory constraints on price discrimination, the optimal mechanism involves the issuer allocating stock to 'regular' institutional investors for subsequent resale to sentiment...

This paper develops a theory of organization based on the benefits and costs of internal capital markets. A central assumption is that the transaction cost of raising external funds is greater than the cost of internal funds. The benefit of internal resource allocation is that it gives the firm...

We examine underwriting fees for repeat issuers of new securities to determine the relation between loyalty to an underwriting bank and the fees charged. For a sample of offers over the 1975-2001 period, we find that loyalty is associated with lower fees for common stock offers, consistent with...

This paper provides a model that explains the structure of mutual funds. Specifically, the paper explains why funds structure as open- or closed-end funds, and why some open-end funds charge loads. In our model fund managers generate earn excess returns that, on the margin, are increasing in...

We argue that in the after-market trading of an IPO, the underwriting syndicate, by standing ready to buy back shares at the offer price (quot;price stabilizationquot;), compensates uninformed investors ex post for the adverse selection cost they face in bidding for IPOs. This dominates ex ante...
