In the first three decades of CRSP data, value stocks have higher betas than growth stocks.Later on, the ranking is reversed and the gap in beta widens. What makes growth strategiesnowadays bear more market risk than value strategies? What are the causes of the reversalin the ranking of betas?...

The end of the lockup period of initial public offerings generally constitutes the first time corporateinsiders sell significant numbers of shares on the market. I test the hypothesis that shareholderspressure analysts to support the share price until the end of the lockup period.[...]

We develop a method that allows one to compute incomplete-market equilibria routinely forMarkovian equilibria (when they exist). The main difficulty to be overcome arises from the setof state variables. There are, of course, exogenous state variables driving the economy but, in anincomplete...

Multiplicity of equilibria is a prevalent problem in many economic models. Oftenequilibria are characterized as solutions to a system of polynomial equations. This pa-per gives an introduction to the application of GrÄobner basis methods for ¯nding allsolutions of a polynomial system. The...

Theoretical models predict that the value of a real option should be increasing in the volatility ofthe underlying asset. Thus, if real options are economically important, then firm values should bepositively related to volatility. Consistent with this prediction, we find evidence that stock...

This paper examines the effects of capital gains taxation on firms’ investmentand financing decisions. We develop a real options model in which the timing ofinvestment, the decision to default, and the firm’s capital structure are endogenouslyand jointly determined. Our analysis demonstrates...

This paper develops a tractable real options framework to analyze the eects of asym-metric information on investment and nancing decisions when rms require externalfunds to nance investment. Our analysis shows that corporate insiders can signal theirprivate information to outside investors using...

This paper examines the impact of agency conicts on corporate nancing decisions. Werst build a dynamic contingent claims model in which nancing policy results from a trade-obetween tax benets, contracting frictions, and agency conicts. In our setting, partially-entrenched managers set the rms'...

Between 1999 and 2007, WR Hambrecht has completed 19 IPOs in the U.S. usingan auction mechanism. We analyze investor behavior and mechanism performance inthese auctioned IPOs using detailed bidding data. The existence of some bids posted athigh prices suggests that some investors (mostly retail)...
