On dividends in the phase–type dual risk model

The dual risk model assumes that the surplus of a company decreases at a constant rate over time, and grows by means of upward jumps which occur at random times with random sizes. In the present work, we study the dual risk renewal model when the waiting times are phase-type distributed. Using the roots of the fundamental and the generalized Lundberg’s equations, we get expressions for the ruin probability and the Laplace transform of the time of ruin for an arbitrary single gain distribution. Then, we address the calculation of expected discounted future dividends particularly when the individual common gains follow a phase-type distribution. We further show that the optimal dividend barrier does not depend on the initial reserve. As far as the roots of the Lundberg equations and the time of ruin are concerned, we address the existing formulae in the corresponding Sparre-Andersen insurance risk model for the first hitting time, and we generalize them to cover also the situations where we have multiple roots. We do that working a new approach and technique, approach we also use for working the dividends, unlike others, it can be also applied for every situation.     

Performance measurement in universities: ambiguities in the use of quality versus quantity in performance indicators

Performance measurement (PM) is now common in Western universities. This is also the case in Finland, where a new funding scheme was implemented to ensure that quality was included in universities’ PM. However, this paper shows that the quality indicators in use are, in practice, quantitative. The paper is based on a large survey and has implications for university PM systems in Finland and internationally.     

Investors’ Fear and Herding Behavior: Evidence from the Taiwan Stock Market

This article analyzes the influence of investors’ fear on their investment behavior in the Taiwan stock market. This study used the volatility index (VIX) as a barometer of investors’ fear. Our results show that herding behavior increases with the VIX; that is, herding behavior is encouraged by an increase in investors’ fear. Moreover, our results demonstrate that investors react more quickly to bad news than to good news when their fear increases, supporting the hypothesis of the presence of an asymmetric reaction to news. However, investors react more quickly to good news when their fear decreases, indicating an inverse asymmetric reaction. In addition, our empirical results reveal that herding behavior tends to exist on days with a large trading volume.
