The estimation of the discount rate for an investment project in conditions of risk relies upon two crucial assumptions: market completeness and well-diversified investors. Although, these two assumptions are tenable in developed capital markets, they are not suitable in emerging markets. In...

This paper explores the implications of investors’ everyday mild feelings for aggregate asset returns. To this end, it introduces a novel class of state dependent preferences - happiness maintenance preferences - into the standard Mehra and Prescott (1985) economy by allowing investors’...

This paper decomposes the overall market beta of common stocks into four parts reflecting uncertainty related to the long-run dynamics of stock- specific and market-wide cash flows and discount rates. We employ a discrete time version of Merton�s Intertemporal CAPM to test whether these four...

This paper investigates association between portfolio returns and higher-order systematic co-moments at different timescales obtained through wavelet multi-scaling- a technique that decomposes a given return series into different timescales enabling investigation at different return intervals....

In an earlier paper (Los, 1998a), the exact and complete return attribution framework of Singer and Karnosky (1995) was extended to include market risk measurements for n countries. Exploiting a selection matrix based on the cash accounting identities, the resulting degenerate portfolio choice...

This paper offers a review of investment performance appraisal methods. The review starts with an exhaustive coverage of various methods ranging from early measures of risk-adjusted return to more recent methods including the rating given by ASSIRT, a financial services organisation that assess...

In this paper, the volatility of the return generating process of the market portfolio and the slope coefficient of the market model is assumed to follow a Markov switching process of order one. The results indicate very strong evidence of volatility switching behaviour in a sample of returns in...

In this paper we present a continuous time dynamical model of heterogeneous agents interacting in a financial market where transactions are cleared by a market maker. The market is composed of fundamentalist, trend following and contrarian agents who process information from the market with...

Se han analizado 6 grupos de variables en un intento de explicar el retorno futuro de las acciones utilizando el CAPM en España. Específicamente, se han realizado variadas simulaciones históricas y regresiones de corte transversal de los retornos de las acciones componentes de la muestra...

A number of empirical studies have reached the conclusion that stock price volatility cannot be fully explained within the standard dividend discount model. This paper proposes a resolution based upon a model that contains both a random supply of risky assets and finitely lived agents who trade...
