Pricing vulnerable options with stochastic volatility

Abstract: In this paper, we investigate the pricing issue of vulnerable options with stochastic volatility by decomposing stochastic volatility into the long-term and short-term volatility. We describe the short-term fluctuation of stochastic volatility using a mean-reverting process, and assume the long-term volatility to be a constant. Based on the proposed model, we derive a pricing formula of vulnerable options in a special case. Numerical results are presented to illustrate the impacts of two stochastic volatility components on vulnerable option prices.

A comparative analysis of the work values of Greece's ‘Millennial’ generation

Abstract: This study adds to the growing body of international evidence concerning the millennial generation (ie those born after 1980), by documenting the work values of millennial-aged undergraduate students (N = 649) in Greece, using an adapted version of the Lyons Work Value Survey Our results show that millennial-aged Greeks place most importance on intrinsic and social aspects of work, and less importance on extrinsic and prestige values We statistically compare our results to those of published studies of millennial-aged respondents from other countries and find that Greek respondents hold a unique work value profile, although they demonstrate some similarities to counterparts in other countries Our findings do not clearly support the notion of a ‘global youth generation’, as young people in various countries hold different work value priorities This suggests that employers seeking to recruit, engage and retain young workers internationally must tailor their offerings to the specific cultural context

Process and quality improvement using six sigma in construction industry / Proceso tobulinimas ir kokybės gerinimas statybų sektoriuje taikant „šešių sigma“ metodą

Abstract: Construction industry presents an extremely complex combined process, production flow, various structures, high quality requirements and long construction cycle. Large quantities of concrete and time are wasted during building construction due to management procedures, construction processes and reworks. Besides, the final construction quality cannot fully meet customer requirements. This paper explores practical solutions for construction process and quality improvement by using prefabricated composite structure (PCS) based on Six Sigma method. The D-M-A-I-C model of Six Sigma has been applied to conduct the analysis of the construction process, to discover essential factors to improve and thus to achieve higher customer satisfaction. This research finds out what influences construction process, construction quality and then adopts design and technique correction measures. It improves the construction process, quality resistance to various performances and proposes the best mix proportion. These...
