This study estimates liquidity premiums using the recently developed Liu (2006) measure within a multifactor capital asset pricing model (CAPM) including size premiums and a time varying parameter model for the West African emerging market of Nigeria. The evidence suggests that liquidity factors...

This paper uses the cross-sectional variance of the betas from the CAPM model to study herd behavior towards market index in Romania. For time-varying beta determination, three different modeling techniques are employed: two bivariate GARCH models (DCC and FIDCC GARCH), two Kalman filter based...

In this paper we review the main theoretical financial indicators developed to evaluate investment portfolios, as Jensen’s Alpha, Treynor Index, based on risk as portfolio’s beta, as well as Sharpe’s index based on risk as volatility. Then, we show the fundamentals of conditional...

Although portfolio management didn’t change much during the 40 years after the seminal works of Markowitz and Sharpe, the development of risk budgeting techniques marked an important milestone in the deepening of the relationship between risk and asset management. Risk parity then became a...

Determining the cost of equity is one of the most difficult problems in corporate finance. In this paper, we present a simple estimation example using an internet start-up company. We use public firm comparables for beta, making adjustments for leverage using Harris and Pringle’s (1985)...

Introductory investments courses revolve around Harry Markowitz’s modern portfolio theory and William Sharpe’s Capital Asset Pricing Model. Nonetheless, the textbook versions of these seminal contributions tend to obscure their economic insights, focusing instead on their...

Risk exchange is considered here as a cooperative game with transferable utility. The set-up fits markets for insurance, securities and contingent endowments. When convoluted payoff is concave at the aggregate endowment, there is a price-supported core solution. Under variance aversion the...

Considering the investment in education as uncertain financial decision making we modify the short-cut method of calculating rates of return to education by incorporating the risk premium. Recognizing that market risk isn’t the only factor affecting returns, we estimate the returns to...

Este documento aplica el modelo capm para una muestra de 38 acciones (80% del mercado) que se cotizaron en la Bolsa de Valores de Colombia durante 2007 y 2008. Las acciones se agruparon en cinco sectores económicos, encontrándose los siguientes resultados: 1. Todos los sectores oscilan en...

There is no consensus in the literature as to which model should be used to estimate stock returns and the cost of capital in the emerging markets. The Capital Asset Pricing Model (CAPM), which is most often used for this purpose in the developed markets, has a poor empirical record and is...
