In this article we study jump spillover effects between a number of country equity indexes. In order to identify the latent historical jumps of each index, we use a Bayesian approach to estimate a jump-diffusion model on each index. We look at the simultaneous jump intensities of pairs of...

This paper examines the impact of estimation error in a simple single-period portfolio choice problem when the investor has power utility and asset returns are jointly lognormally distributed. These assumptions imply that such an investor selects portfolios using a modified mean-variance...

The home bias is defined as the tendency of the investors to invest a larger proportion of their wealth in domestic equities than what would be optimal based on the meanvariance principle. There are several explanations for this observed home bias, e.g., barriers to foreign investments and...

This paper analyses the ability of beta and other factors, like firm size and book-to-market, to explain cross-sectional variation in average stock returns on the Swedish stock market for the period 1980-1997. We use a bivariate GARCH(1,1) process to estimate time-varying betas for asset...

Our aim is to give a comparative analysis of ability of different factor mimicking portfolios in representing the background factors. Our analysis contains a cross-sectional regression approach, a time-series regression approach and a portfolio approach for constructing factor mimicking...

This paper evaluates the usefulness of the orthogonal portfolio approach proposed by MacKinlay and Pastor (2000), for the estimation of the expected returns of Swedish industrial portfolios from 1980 to 1997. In this approach the expected returns are linked to the residual covariance matrix of a...

The common approach for constructing factor mimicking portfolios is to go long in assets with high loadings and to short-sell those with low loadings on some background factors. As a result portfolios containing stocks with low loading on the background factor receive negative betas against the...

Our purpose is to find factors that are important for expected returns and risk of Swedish industrial portfolios. We have chosen factors that are important for a small open economy. We take into account the small sample problem that surfaces as firms dominating the value weighted test...

We develop a model of stochastic volatility with jump to analyze how the local equity markets of the European countries are affected by the regional equity market (other European equity markets) and the US equity market. Our approach simultaneously investigates all the three aspects of the...
