Capital Asset Pricing Model (CAPM) provides an equilibrium linear relationship between expected return and risk of an asset. The purpose of this paper is to investigate a risk-return relationship within the CAPM framework. The study also aims at exploring whether CAPM is a good indicator of asset pricing in Bangladesh. For this study, a period 19992003 have been considered. Fama-French [1992] m...

Recent literature (McNulty, Yeh, Schulze, & Lubatkin, 2002) states that the assumptions behind the capital asset pricing model, in particular the irrelevance of time horizon, do not correspond to the characteristics of firms that prefer long-term investment horizons. I show that family firms display a longer time horizon than most of their nonfamily counterparts, since (1) family firms display ...

We investigate the properties of mean-variance efficient portfolios when the number of assets is large. We show analytically and empirically that the proportion of assets held short converges to 50% as the number of assets grows, and the investment proportions are extreme, with several assets held in large positions. The cost of the no-shortselling constraint increases dramatically with the num...

In this paper we propose a new approach to estimating the systematic risk (the beta of an asset) in a capital asset pricing model (CAPM). The proposed method is based on a wavelet multiscaling approach that decomposes a given time series on a scale-by-scale basis. At each scale, the wavelet variance of the market return and the wavelet covariance between the market return and a portfolio are ca...

This paper highlights some aspects of the many facets of electricity distribution system risk assessment – describing the different risk consequence categories which are relevant in the whole risk picture with regards to their characteristics, their type of impact and applicable risk analysis methods. The paper illustrates that distribution system asset management constitutes of a variety of mo...

The quality of information in financial asset markets is often hard to estimate. This paper analyzes information transmission in asset markets when agents treat information of unknown quality as ambiguous. We study the effects of information ambiguity on asset prices, trading volume, and market liquidity in noisy rational expectations equilibrium. We consider a market with risk-averse informed ...

In this paper we study the effects of transaction costs on asset prices. We assume an overlapping generations economy with two riskless assets. The first asset is liquid while the second asset carries proportional transaction costs. We show that agents buy the liquid asset for short-term investment and the illiquid asset for long-term investment. When transaction costs increase, the price of th...

In 2007 ‘‘the state of asset management in the Netherlands’’ for infrastructures was established by a national study conducted by the Next Generation Infrastructures research programme (NGInfra). This study showed that within the Netherlands different interpretations of asset management exist. The way asset management is implemented in practice differs widely. Differences included tools, proces...
