In the standard CAPM with a riskless asset we give a simple proof of existence of equilibria without assuming concavity of the investor's utility functions. Moreover, we give a uniqueness result using assumptions on the risk aversion of investors.

Consider an investor trading dynamically to maximize expectedutility from terminal wealth. Our aim is to study the dependencebetween her risk aversion and the distribution of the optimal terminalpayo. Economic intuition suggests that high risk aversion leads to arather concentrated distribution,...

Portfolio choice and the implied asset pricing are usually derived assumingmaximization of expected utility. In this Paper, they are derived from risk-value models that generalize the Markowitz-model. We use a behaviourally-based risk measure with an endogenous or exogenous benchmark...

We examine whether consumer confidence – as a proxy for individual investor sentiment –affects expected stock returns internationally in 18 industrialized countries. In line with recentevidence for the U.S., we find that sentiment negatively forecasts aggregate stock marketreturns on average...

Using a new data set on investor sentiment we show that institutional and individualsentiment proxy for smart money and noise trader risk, respectively. First, usingbias-adjusted long-horizon regressions, we document that institutional sentiment forecastsstock market returns at intermediate...

The CAPM can explain closed-end fund (CEF) discounts as a consequence of the higherbetas on CEF shares than on their underlying portfolios. The difference in betas is muchgreater for international funds and for bond funds than for domestic equity funds. CEFshares carry both more idiosyncratic...
