Mutual fund performance evaluation: a comparison of benchmarks and benchmark comparison
Article Abstract:
The authors' main goal in this paper is to ascertain whether conventional measures of abnormal mutual fund performance are sensitive to the benchmark chosen to measure normal performance. They employ the standard CAPM benchmarks and a variety of APT benchmarks to investigate this question. They find little similarity between the absolute and relative mutual fund rankings obtained from these alternative benchmarks, which suggests the importance of knowing the appropriate model for risk and return in this context. In addition, the rankings are not insensitive to the method used to construct the APT benchmark. Finally, they find statistically significant measured abnormal performance using all the benchmarks. The economic explanation for this phenomenon appears to be an open question. (Reprinted by permission of the publisher.)

Orthogonal frontiers and alternative mean-variance efficiency tests
Article Abstract:
This paper catalogues properties of minimum norm orthogonal portfolios: portfolios which minimize a quadratic objective function and have returns uncorrelated with those of a candidate portfolio that is not mean-variance efficient. The analysis shows that the dollar versions of these portfolios correspond to estimators of zero beta rates based on alternative statistical criteria and grouping procedures while costless orthogonal portfolios represent candidate mean-variance efficiency tests. It also develops inference procedures for zero and unit net investment portfolios of individual securities (instead of grouped portfolios) that have zero expected betas. The resulting mean-variance efficiency tests are reasonably insensitive to the underlying statistical assumptions. (Reprinted by permission of the publisher.)

Effects of capital gains taxation on life-cycle investment and portfolio management
Article Abstract:
We examine the impact of capital income taxation, both accrual forms of taxation and taxation of realized capital gains, on total savings and the demand for corporate financial instruments. We find that investors may hold both debt and equity in the face of effective collection of capital gains taxation even in a flat tax system. We also find that the two taxes will have substantially different effects on saving and consumption behavior, making it unlikely that the tax structure can be summarized by any single equivalent accrual tax rate.
