A decomposition formula for option prices in the Heston model and applications to option pricing approximation

By means of classical It? calculus, we decompose option prices as the sum of the classical Black?CScholes formula, with volatility parameter equal to the root-mean-square future average volatility, plus a term due to correlation and a term due to the volatility of the volatility. This decomposition allows us to develop first- and second-order approximation formulas for option prices and implied volatilities in the Heston volatility framework, as well as to study their accuracy for short maturities. Numerical examples are given.     

KNOW YOUR CLIENT! INVESTOR PROFILE AND TAILOR‐MADE ASSET ALLOCATION RECOMMENDATIONS

We study how the investor profile influences the asset allocation recommendations of professional advisors. We find the investor's perceived risk attitude influences more the mix of risky assets, whereas the socioeconomic variables influence more the cash percentage. The recommendations are consistent with a diversification behavior driven by actual asset correlations. These findings support the utility of investor advisory that may help enhance the risk and return trade‐off. The main drawback of the recommendations may consist in the degree of customization that is limited by the small number of investor characteristics actually influencing the asset allocation.     

Opportunities for commercial accommodation in VFR travel

This research explores the extent to which VFR travellers utilise commercial accommodation in the Sunshine Coast, Australia, and profiles the characteristics and behaviours of this particular type of VFR traveller. The research indicated that 26% of the VFRs stayed in commercial accommodation (CVFRs). This closely aligned with research using the same method in a comparative destination, Ballarat, Australia, indicating that 22% of VFRs stayed in commercial accommodation. CVFR travellers occupied similar types of commercial accommodation as non‐VFRs and engaged in similar tourism activities. However, they came from different generating regions and used different sources of information for planning their trip. Copyright © 2009 John Wiley & Sons, Ltd.     

Global Standards and Ethical Stock Indexes: The Case of the Dow Jones Sustainability Stoxx Index

The increased scrutiny of investors regarding the non-financial aspects of corporate performance has placed portfolio managers in the position of having to weigh the benefits of ‘holding the market’ against the cost of having positions in companies that are subsequently found to have questionable business practices. The availability of stock indexes based on sustainability screening makes increasingly viable for institutional investors the transition to a portfolio based on a Socially Responsible Investment (SRI) benchmark at relatively low cost. The increasing share of socially responsible investments may play a role in providing incentives towards a continuous upgrading of sustainability standards to the extent that their performance is not systematically inferior to that of the other funds. This article examines whether these incentives have been so far detectable with particular reference to the Dow Jones Sustainability Stoxx Index (DJSSI) that focuses on the European corporations with the highest CSR scores among those included in the Dow Jones Stoxx 600 Index. The aim of the article is twofold. First, we analyse the performance of the DJSSI over the period 2001–2006 compared to that of the Surrogate Complementary Index (SCI), a new benchmark that includes only the components of the DJ Stoxx 600 that do not belong to the ethical index to evaluate more correctly the size of possible divergent performances. Second, we perform an event study on the same data set to analyse whether the stock market evaluation reacts to the inclusion (deletion) in the DJSSI. In both cases, the results suggest that the evaluation of the CSR performance of a firm is a significant criterion for asset allocation activities.     

Value Priorities as Combining Core Factors Between CSR and Reputation – A Qualitative Study

This article explores the nature of corporate social responsibility (CSR) and corporate reputation using qualitative research approach. Specifically, the relationship between CSR and corporate reputation is examined from the viewpoint of value theory. This paper brings up for discussion the various value priorities lying in the background of CSR actions. The aim is to form categories of value priorities around CSR and reputation, based on qualitative research approach. The main concepts in this paper – CSR, reputation and value – are also defined. This paper further discusses the theory of value structure and content, which identifies certain principal values among different cultures. The data consist of eight interviews with employees of a newspaper company. The results suggest that value priorities play an influential role in CSR actions, influencing to the essence of certain reputation stories in the corporate context.     

To Help or Not to Help? Personal Value for Diversity Moderates the Relationship Between Discrimination Against Minorities and Citizenship Behavior Toward Minorities

Using the scope of justice perspective (Deutsch in J Soc Issues 31(3):137–149, 1975; Opotow in Conflict, cooperation, and justice: essays inspired by the work of Morton Deutsch, 1995, J Soc Issues 52:19–24, 1996), we examined whether and how the relationship between perceived discrimination against minorities at work (i.e., racial minorities and females) and citizenship behavior toward minorities can be modified by personal value for diversity. Based on a survey of 173 employees, unexpectedly, we found a negative relationship between perceived discrimination against minorities at work and citizenship behavior toward minorities. However, consistent with our expectations and the scope of justice, we found that the negative relationship was attenuated for those high in personal value for diversity.     

Brand Personality of Global Quick-Service Restaurants in Emerging and Developed Markets: A Comparative Study in Brazil and the U.S.

This study aimed to determine the dimensions of the personality of global quick-service restaurant brands perceived by young consumers in the U.S. and Brazil, and whether these dimensions showed similar configurations in both countries. A survey was carried out with two QSR brands (McDonald's and Subway). Data analysis utilized exploratory and confirmatory factor analysis. The study identified five personality dimensions for each of the brands studied in each country. Results support the proposition that global brands can carry a common meaning across nations, but also that certain local nuances of brand personalities can differ.     

Trade,foreign direct investments (FDI) and income inequality: Empirical evidence from transition countries

The aim of the article is to verify whether trade and inward foreign direct investments (FDI) may affect income distribution in a sample of 17 Transition Countries (TCs) over the period 1990–2006. In line with most of the previous literature, FDI do not have significant effects on income inequalities, whereas trade, especially when occurs with developed countries, seems to be more relevant. Different results are found when we take into consideration the educational system which represents an important channel through which FDI and trade may affect inequality.     

Retail service quality as a key activator of grocery store loyalty

This paper demonstrates the crucial role of retail service quality as a key activator in the formation of customer loyalty to the store; the latter is understood in a conative and action sense. Applying a modified version of the RSQS scale, a model is tested by administering a questionnaire to 450 customers in an under-investigated retail setting, i.e. supermarkets, within the Italian context. Structural equation modelling was employed. The results prove that customers consider retail service quality as a second-order dimension and recognize the main contribution of physical aspects and reliability first-order dimensions. Findings corroborate the crucial role played by perceived service quality and the mediating role of customer satisfaction and conative loyalty within the relationship between service quality and action loyalty.
