Based on a sample of 7,378 firms going public in the 1975-2005 period, we document a significant underperformance of IPO firms over the first year after going public, while there is virtually no underperformance thereafter. Moreover, by decomposing the Carhart-alpha we find that IPO...

It is often argued that Black-Scholes (1973) values overstate the subjective value of stock options granted to risk-averse and under-diversified executives. We construct a "representative" Swiss executive and extend the certainty-equivalence approach presented by Hall and Murphy (2002) to assess...

This paper examines properties of mean-variance inefficient proxies with respect to producing a linear relation between expected returns and betas. The numerical results of a Monte Carlo simulation show that in the CAPM slightly inefficient, positively weighted proxies cause an almost perfect...

We present a regression-based generalization of the calendar time portfolio approach which allows for decomposing the risk-adjusted performance of private investors (or firms or mutual funds) into multivariate and continuous subject characteristics. Our technique remedies several well-known...

Using a panel of 425 European firms over the period from 1990 to 2005, we revisit Welch's (2004) finding that stock returns are the primary determinant of capital structure changes and that the corporate motives for issuing activities remain largely unexplained. We document that about half of...
