Implied correlation indices and volatility forecasting

Implied volatility indices are an important measure for ‘market fear’ and well-known in academia and practice. Correlation is still paid less attention even though the CBOE started to calculate implied correlation indices for the S&P500 in 2009. However, the literature especially on cross-country dependencies and applications is still quite thin. We are closing this gap by constructing an implied correlation index for the DAX and taking a deeper look at the (intercontinental) relationship between equity, volatility and correlation indices. Additionally, we show that implied correlation could improve implied volatility forecasting.     

Improving Attitude toward Corporate Strategy with Visual Mapping： Scale Development and Application in Europe and China

Companies operating across borders face greater challenges in ensuring compliance with company strategy in different cultural contexts. Recent research shows the cognitive and emotional benefits of utilizing visual representations of knowledge in organizations. This study aims to test if mapping a corporate strategy visually can improve attitudes toward firm strategy and the intention to comply with it. An experiment is conducted comparing two knowledge maps to a textual version of the same company strategy. In order to measure attitudes toward the strategy, a scale was developed and tested in Europe and China. The study outcome provides a parsimonious and effective tripartite scale of attitude with cognitive, affective and behavioral components. The scale was then applied to a different sample to test the effect of mapping a company strategy visually on attitude toward the strategy, and to test if the effect is persistent in Europe and China. The results of the experiment show that subjects exposed to the visual conditions had significantly more positive affective and cognitive attitudes toward the content.     

You Support Diversity,But Are You Ethical? Examining the Interactive Effects of Diversity and Ethical Climate Perceptions on Turnover Intentions

Efforts to identify antecedents of employee turnover are likely to offer value to organizations through money saved on recruitment and new-hire training. The authors utilized the stakeholder perspective to corporate social responsibility to examine the effects of a perceived climate for ethics on the relationship between diversity climate and voluntary turnover intentions. Specifically, they examined how ethics climate (employees’ perceptions that their organization values and enforces ethically correct behavior) affected the diversity climate–turnover intentions relationship. Results indicated that ethics climate moderated the diversity climate–turnover intentions relationship. Turnover intentions were lowest among workers perceiving both a pro-diversity and highly ethical climate. These results reinforce the need to communicate both diversity values and ethical standards to employees.     

Good guy vs. bad guy: the influence of parasocial interactions with media characters on brand placement effects

Although brand placements are frequently associated with media characters within movies or TV series, and viewers are well known to relate to such characters, previous research has scarcely dealt with media characters’ influence on brand placement effects. Addressing this, two studies investigate the influence of parasocial interactions with media characters on perceptions of brands related to media characters. The first study applied a 1 × 2 between-subjects design, assuming that positively represented characters elicit greater parasocial interaction and, subsequently, more favourable brand attitudes compared with negatively represented characters. The results confirm the assumed indirect effect. A second study was able to replicate the first study's findings in a different setting and to introduce brand familiarity as an important moderator of the mediation found in the first and second study (moderated mediation). The underlying mechanism and implications are discussed.     

Optimization of Monte Carlo Procedures for Value at Risk Estimates

This paper proposes a methodology which improves the computational efficiency of the Monte Carlo simulation approach of value at risk (VaR) estimates. Principal components analysis is used to reduce the number of relevant sources of risk driving the portfolio dynamics. Moreover, large deviations techniques are used to provide an estimate of the minimum number of price scenarios to be simulated to attain a given accuracy. Numerical examples are provided and show the good performance of the methodolgy proposed.

Choosing project risk management techniques. A theoretical framework

The pressure for increasing quality while reducing time and costs places particular emphasis on managing risk in projects. To this end, several models and techniques have been developed in literature and applied in practice, so that there is a strong need for clarifying when and how each of them should be used. At the same time, knowledge about risk management is becoming a matter of paramount importance to effectively deal with the complexity of projects. However, communication and knowledge creation are not easy tasks, especially when dealing with uncertainty, because decision-making is often fragmented and a comprehensive perspective on the goals, opportunities and threats of a project is missing. With the purpose of providing guidelines for the selection of risk techniques taking into account the most relevant aspects characterising the managerial and operational scenario of a project, a theoretical framework to classify these techniques is proposed. Based on a literature review of the criteria to categorise risk techniques, three dimensions are defined: the phase of the risk management process, the phase of the project life cycle and the corporate maturity towards risk. The taxonomy is then applied to a wide selection of risk techniques according to their documented applications. This work helps to integrate the risk management and the knowledge management processes. Future research efforts will be directed towards refining the framework and testing it in multiple industries.     

The evolution of the industrial organisation of the production of knowledge

This work elaborates the notion of localised technological knowledge,based upon the distinction between information, competence andknowledge, and analyses the emergence of the new knowledge industry.The evolution of the organisation of knowledge production isanalysed through four stylised modes: scientific entrepreneurship,institutional variety, vertical integration and technologicalcooperation. The new trends towards the growth of knowledge-intensivebusiness service industries are detected and underlined. Theyare considered as the outcome of the institutional formationof a market for knowledge based upon a process of increasingappropriability of localised knowledge based on: the blendingof generic scientific information and competence and growingscope of applicability via computer-communication systems; deverticalisationof research activities from the boundaries of corporations;the specification of a demand for technological competence;and the specialising of independent firms in the productionof technological competence and knowledge.     

Multiple Origins of Accounting? An Early Italian Example of the Development of Accounting for Managerial Purposes

ABSTRACT

Utilising archival materials relating to an Italian pottery manufacturer, Manifattura Ginori, this paper examines the development of the company's accounting system during the 19th century. By the early 1800s, Manifattura Ginori is shown to have developed a double-entry bookkeeping system and to have carried out cost calculations. Deficiencies in the archive unfortunately do not enable us to determine precisely the nature of the links between the cost calculations and the financial accounting system during the early decades of the 19th century. However, as the century wore on, and the business moved from being an artisanal based manufacturer of high quality porcelain to a large-scale, industrial producer of utilitarian wares, Manifattura Ginori developed its system of accounting to reflect organisational changes and managerial needs. The Ginori archives therefore not only provide us with a rare glimpse of accounting in an early industrial context in Italy, but also of the use of accounting as a mechanism for business management and control in a non-Anglo-Saxon context. In particular it allows us to examine the role of accountants, to throw light on factors causing accounting change, and the relevance of alternative theoretical paradigms in interpreting such changes. By placing the experiences of Manifattura Ginori in a context of developments elsewhere in Europe, especially Britain and France, some implications can be drawn regarding the possibility of multiple origins of accounting ideas.     

The dynamics of relational competencies in the development of born global firms: A multilevel approach

From a multilevel approach, this paper focuses on the born global firms and the relational competencies that they use to initiate, maintain, and expand their international social networks. To do so, we detail the three levels of relational competencies (individual, collective, and organizational) and undertake an exploratory qualitative research based on interviews with French entrepreneurs of born global firms and experts who support their development. This study allows us to reach two sets of findings: firstly, a repository of thirteen relational competencies mobilized in born global firms as well as their development mechanisms; secondly, a dynamic view of these competencies, based on initiation, consolidation and expansion situations in which relational competencies and their development mechanisms are activated. Our study may lead entrepreneurs to identify competencies they hold at all levels (individual, collective, and organizational) but without necessarily implementing, as well as provide keys to develop any that are lacking in order to improve their internationalization strategy.
