Embracing the concept of factor investing, we design a flexible framework for building out different factor completion strategies for traditional multi-asset allocations. Our notion of factor completion comprises a maximally diversified reference portfolio anchored in a multi-asset multi-factor...

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...

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...

We use a dynamic framework and panel methodology to investigate the determinants of a firms' time-varying capital structure. Our sample comprises 706 European firms from France, Germany, Italy and the U.K. over the period from 1983 to 2002. If capital structure adjustment is costly, firms may...
