The main criterion in investment decisions is to maximize the investors utility. Traditional capital asset pricing models cannot be used when asset returns do not follow a normal distribution. For this reason, we use capital asset pricing model with independent and identically asymmetric power distributed (CAPM-IIAPD) and capital asset pricing model with asymmetric independent and identically a...

explanation relation between risk and return and capital asset pricing are concepts which is appointed as dominator and major paradigms in capital markets. so far as after offering capm by sharp & lintner, this model has been revised and criticized frequently. in this paper another version of capm has been tested versus traditional capm in tehran stock exchange. this version of capm measures se...

The choice of model of normal returns in event studies has been widely discussed in the literature. While researchers frequently continue to use an array of alternatives, there is currently some tendency to favour cruder but simpler meanor marketadjusted returns models. This paper presents a general-to-specific model selection framework for testing the data admissibility of the principal models...

Adrian and Franzoni (2005) suggest that beta of a stock is determined by the factor loading of its unobservable long-run beta. The fundamental idea behind this model is that investors engage in a learning process of estimating this long-run beta. In this paper, a variation of this model is tested. Instead of estimating long-run beta, investors try to learn about factor loading. Given the long-r...

We explore theoretically and experimentally the general equilibrium price and allocation implications of delegated portfolio management when the investor-manager relationship is non-exclusive. Investors transfer their securities allocations to managers, managers trade in a competitive marketplace to achieve new allocations, and payo↵s are distributed back to investors after subtraction of a por...

We consider a financial market in which two securities are traded: a stock and an index. Their prices are assumed to satisfy the Black–Scholes model. Besides assuming that the index is a tradable security, we also assume that it is efficient, in the following sense: we do not expect a prespecified self-financing trading strategy whose wealth is almost surely nonnegative at all times to outperfo...

Article history: Received 6 September 2011 Accepted 13 February 2012 Available online 8 March 2012 A number of recent papers have developed multifactor extensions of the classic consumption capital asset pricing model (CCAPM) and generally concluded that conditioning information improves the empirical performance. This paper asks whether the superior empirical performance of the multifactor CCA...

Forward exchange rate unbiasedness is rejected in tests from the current floating exchange rate era. This paper surveys advances in this area since the publication of Hodrick's (1987) survey. It documents that the change in the future exchange rate is generally negatively related to the forward discount. Properties of the expected forward forecast error are reviewed. Issues such as the relation...
