This study develops and implements a theory and method for analyzing whether introducing new securities or relaxing investment constraints improves the investment opportunity set for risk averse investors. We develop a test procedure for ‘stochastic spanning’ for two nested polyhedral...

Contemporary financial stochastic programs typically involve a trade-off between return and (downside)-risk. Using stochastic programming we characterize analytically (rather than numerically) the optimal decisions that follow from characteristic single-stage and multi-stage versions of such...

We introduce a novel criterion for performance measure combination designed to be used as an equity screening algorithm. The proposed approach follows the general idea of linearly combining existing performance measures with positive weights and the combination weights are determined by means of...

We analyze the results of a recent survey of U.S. Chief Financial Officers (CFOs) conducted in 2008. We present expectations of the equity risk premium measured over a 10-year horizon relative to a 10-year U.S. Treasury bond. This multi-year survey has been conducted every quarter from June 2000...

To analyze persistence in mutual fund performance, it is common practice to construct portfolios of funds based on past fund returns. Using a large sample of equity and bond funds, we show that this approach introduces dynamic exposures to common stock and bond risk factors. Correcting for risk...

Traditional mean-variance efficient portfolios do not capture the potential wealth creation opportunities provided by predictability of asset returns. We propose a simple method for constructing optimally managed portfolios that exploits the possibility that asset returns are predictable. We...

We analyze the results of the most recent survey of U.S. Chief Financial Officers (CFOs) which looks ahead to the first quarter of 2007 and beyond. We present expectations of the equity risk premium measured over a 10-year horizon relative to a 10-year U.S. Treasury bond. This multi-year survey...

People are more willing to bet on their own judgments when they feel skillful or knowledgeable (Heath and Tversky, 1991). We investigate whether this 'competence effect' influences trading frequency and home bias. We find that investors who feel competent trade more often and have more...

We analyze the results of the most recent survey of U.S. Chief Financial Officers (CFOs) which looks ahead to the first quarter of 2006 and beyond. We present expectations of the equity risk premium measured over a 10-year horizon relative to a 10-year U.S. Treasury bond. This multi-year survey...
