Commodity and equity markets: Some stylized facts from a copula approach

In this paper, we propose to identify the dependence structure that exists between returns on equity and commodity futures and its development over the past 20 years. The key point is that we do not impose any dependence structure, but let the data select it. To do so, we model the dependence between commodity (metal, agriculture and energy) and stock markets using a flexible approach that allows us to investigate whether the co-movement is: (i) symmetrical and frequent, (ii) (a) symmetrical and mostly present during extreme events and (iii) asymmetrical and mostly present during extreme events. We also allow for this dependence to be time-varying from January 1990 to February 2012. Our analysis uncovers three major stylised facts. First, we find that the dependence between commodity and stock markets is time-varying, symmetrical and occurs most of the time (as opposed to mostly during extreme events). Second, not allowing for time-varying parameters in the dependence distribution generates a bias towards an evidence of tail dependence. Similarly, considering only tail dependence may lead to false evidence of asymmetry. Third, a growing co-movement between industrial metals and equity markets is identified as early as 2003; this co-movement spreads to all commodity classes and becomes unambiguously stronger with the global financial crisis after Fall 2008.     

What Drove the Massive Hoarding of International Reserves in Emerging Economies? A Time‐varying Approach

Existing empirical models fail to explain the surge in the accumulation of foreign exchange reserves by emerging countries during the last decade. This paper provides an estimate of the demand for international reserves on a panel of emerging countries using a time‐varying panel smooth transition regression (TV‐PSTR) model to relax the assumption of coefficient stability in the relationship. Evidence is dound that the parameters are not constant. In addition, it is observed that the coefficients remained relatively stable until 2000 and then increased gradually and strongly thereafter. The specification provided here accounts for an acceleration that linear specifications fail to explain. Finally, it is found that mercantilist motives are the major driver of this acceleration.     

Co-operation and co-opetition as open innovation practices in the service sector: Which influence on innovation novelty?

This study aims to identify the influence of co-operation practices and the use of internal and external information sources on the propensity of firms to introduce new to the market innovations in the service sector. Data come from the 4th Community Innovation Survey, which covers the years 2002-2004. A logistic regression model is applied with the degree of novelty of good/service innovation as dependent variable. The analysis of the parameter estimates shows that firms provided with information from market sources and from internal sources as well as firms involved in science-based collaboration for their product innovations are more likely to introduce new to the market innovations, whereas information coming from competitors seems to have a negative influence on the degree of novelty of innovation.     

Has the CDS market influenced the borrowing cost of European countries during the sovereign crisis?

This paper assesses the potential influence of the growing CDS market on the borrowing cost of sovereign states during the European sovereign crisis. We analyze the sovereign debt market to ascertain the pattern of information transmission between the CDS and corresponding bond markets. Our methodological innovation is the use of a non-linear specification rather than the linear VECM specification customarily employed. Using a panel smooth transition model during the 2008–2010 period, we find that: 1) linearity tests clearly reject the null hypothesis of a linear transmission mechanisms between the bond and the CDS markets; 2) market distress alters the mutual influence and 3) the higher the distress the more the CDS market dominates the information transmission between CDS and bond markets.     

In search of consensus: The role of accounting in the definition and reproduction of dominant interests

This article examines the role of accounting in the manufacture of consensus. Consensus building is often considered a central value for rational decision-making and management. However, more than a democratic confrontation of vantage points, the quest for consensus is a way to discourage conflict and resistance. Our main argument is that accounting and consensus play central roles in processes of definition and the social reproduction of dominant interests. Accounting acts to promote some stakes and strategies (and silence others), as if they were collective and disinterested, which makes them more powerful in debates that deny struggles and asymmetries in positions of power, as well as increases legitimacy by creating an illusion of participation. We illustrate these processes through a case study in which we document the intersection between two fields of knowledge, marketing and accounting, that compete for a monopoly on the definition of value and the ability to speak for the organisation. This analysis draws on Bourdieu's conceptualisation of symbolic domination to highlight how powerful actors secure influence while avoiding contestation. Accounting produces symbolic violence that consolidates asymmetries in positions of power by shaping what is consensual and what is not so that dominant interests are reproduced with the consent of those who have most to lose in the process.     

Functional Eating and Strategic Groups in Canada

The emergence of the nutraceuticals and functional foods (NFFs) products is a challenge to economists and management scientists interested in studying the evolution of the sector. There are profound issues in product and in market classification. This paper reports the results of an exploratory study that illustrates the use of strategic groups as a means to research this emerging industry, using a sample of 280 companies in Canada. The analysis identifies six main strategic groups within the NFFs sector that compete on the market, product and capability strategic fields. The results indicate that the sector is widely heterogeneous in firm composition, markets served, and intragroup and intergroup product strategies.
L'émergence de produits nutraceutiques et aliments fonctionnels (NAF) pose un défi aux économistes et aux spécialistes en sciences administratives intéressés par l'étude de I'évolution de ce secteur où perdurent de nomhreux prohlémes de classification de produits et de marchés. Cet article présente les résultats d'une étude exploratoire qui démontre la pertinence de la notion de groupe stratégique dans l'analyse d'un échantillon de 280 compagnies de ce secteur au Canada. Cette etude identifie six groupes strategiques dans le secteur des NAF en concurrence au plan des champs stratégiques de marchés, de produits et de compétences. Les résultats de la recherche montrent que le secteur est largement hétérogène au niveau de la composition des firmes, des marchés desservis et des stratégies de produits intergroupes et intragroupes.     

Clarifying the construct of human resource systems: Relating human resource management to employee performance

Strategic human resource management researchers have strongly advocated a system perspective and provided considerable evidence that certain systems of human resource practices have a significant impact on individual and organizational performance. Yet, challenges of understanding the construct of human resource systems still remain in the literature. Specifically, few efforts have been made to explicate the internal fit in human resource systems referring to how the practices in human resource systems work together. For the purpose of clarifying human resource systems construct, we review the components of human resource systems and delineate how the parts of human resource systems work together to influence employee performance. Theoretical and empirical implications for future research are also discussed.     

Exploring the role of perceived external prestige in managers' turnover intentions

Employee turnover is an important topic in the human resource management literature. Several researchers have sought to analyse its multiple determinants and to model the turnover process. The purpose of this paper is to study the impact of employees' perception of the external image of the company they work for on their intentions to leave. It is based on a questionnaire survey of 801 French managers that attempted to incorporate the notion of perceived external prestige (PEP) within the literature's classical model of turnover. The results show that the impact of PEP on intentions to leave is partially mediated by the two determinants of turnover in the model: organizational commitment and job satisfaction. Yet there still remains a direct effect of PEP on intentions to quit. Our research also attempted to confirm the existence of a possible moderator effect, but was unable to find such an effect.     

Indirect networks: an intangible resource for biotechnology innovation

In the context of the emergence of new modular organizational forms, especially in high-tech sectors such as the biotechnology sector, this article proposes that while a firm observes benefits from direct alliances, it also benefits from indirect linkages. First, a theoretical framework revolving around indirect ties is built on the basis of social network and innovation management literature. It ends with the proposition of two research hypotheses linking the indirect network position of a firm to its innovation capacities. To test those hypotheses, data on strategic partnerships and collaborations were collected through 40 interviews with biotech firms from the nutrition sector in the biotech clusters of Quebec (Canada). Using network analysis, centrality measures and hierarchical regressions, results of this study indicate that by occupying a central position in a network of indirect ties, a firm is more likely to access useful knowledge from its direct partners and increase innovation. We suggest, as a conclusion, that indirect network position could be considered as an intangible strategic resource for biotech firms.
