Simulation Monte Carlo methods in extended stochastic volatility models

A new technique for nonlinear state and parameter estimation of discrete time stochastic volatility models is developed. Algorithms of Gibbs sampler and simulation filters are used to construct a simulation tool that reflects both inherent model variability and parameter uncertainty. The proposed chain converges to equilibrium enabling the estimation of unobserved volatilities and unknown model parameter distributions. The estimation algorithm is illustrated using numerical examples. Copyright © 2002 John Wiley & Sons, Ltd.     

The importance of focus for generating customer value

A carefully chosen customer value proposition (CVP) is essential to create customer value. Both value creation from the customer and the corporate viewpoint gain from consistent and deliberate focus on key market segments and core competences. The result is a mutual exchange of value, thus stabilising and strengthening the competitive position in the market. Conversely, failure to maintain a consistent focus puts value creation at risk, and potentially causes one's competitive position to break down. System Theory offers a useful framework to integrate value creation from both the customer and the corporate perspective.     

AN ANALYSIS OF THE FINANCIAL MANAGEMENT TECHNIQUES CURRENTLY EMPLOYED BY LARGE U.S. CORPORATIONS

Economic conditions have placed increased importance upon rigorous financial analysis. In order to determine which analytical techniques are currently emp loyed by management, a questionnaire was sent to each fm on the May 1980, FORTUNE 500 list. The researchsought to establish a profile of the respondents' organizational structure and to identify the primary procedures used in risk assessment, working capital management, capital budgeting, and operations research modeling. The results do suggest a basic profile of the more active employers of analytical techniques. Relatively sophisticated capital budgeting procedures appear to be accepted across most industries, and many firms support their decision making with a "package" of formal tools.     

The effect of distribution channels on mutual fund flows

The Morningstar fund rating has been reported to affect mutual fund flows in the US markets. This paper finds that flow patterns in Finnish bank-managed funds are significantly different from the patterns in the US. Specifically, non-bank funds attract flows in a manner similar to the US markets, that is Morningstar ratings affect fund flows. In contrast, Finnish bank-managed funds do not exhibit the same relationship between star ratings and flows. The results suggest that in Finland, five-star Morningstar ratings are not regarded as highly as in the US, where good performance attracts significantly higher flows. More significantly, our findings demonstrate the importance of banks' distribution channels in the Finnish financial market.
