Mired in deception: escalating an environmental disaster in Colombia
No full textInternational audienceThis paper aims to analyze concealment and deception in self-defeating organizational crisis response strategies and the possible consequences of their adoption on a company’s reputation. It represents an example of where every guideline to address stakeholders after a crisis was dismissed
IT-enabled knowledge ambidexterity and innovation performance in small U.S. firms: The moderator role of social media capability
No full textInternational audienceThis study examines the impact of information technology (IT)-enabled knowledge ambidexterity on innovation performance, and the potential moderator role of social media capability on a sample composed of 100 small U.S. firms. The empirical analysis suggests that IT infrastructure enables the firm to explore new knowledge and exploit existing/new knowledge to innovate more and better. We also find that social media capability has a positive moderator role in this equation: IT infrastructure and social media capabilities work together to enable knowledge ambidexterity
Time-varying evidence of efficiency, decoupling, and diversification of conventional and Islamic stocks
No full textInternational audienceThis study investigates the efficiency of conventional and Islamic stock markets and their diversification potential by using multifractal de-trended fluctuation analysis (MF-DFA), wavelet squared coherence (WTC) and wavelet Value-at-Risk (VaR). Evidence from regional and country-level markets indicates Islamic stocks are less efficient than conventional ones in the short term, however more efficient in the medium term. Conventional stocks in the UK, Japan, and emerging markets are more efficient than the Islamic ones in the long term, whereas those from the US and Europe are less efficient. The wavelet VaR shows that conventional stock markets are at least as risky as the Islamic ones

MNCs' industrial linkages and environmental spillovers in emerging economies: The case of China
No full textInternational audienceMost studies investigating the mechanisms through which companies can reduce their environmental footprint have been conducted in the context of developed economies. However, corporate environmentalism in emerging economies is also an important and timely topic. Emerging economies will soon account for more than half of the global emissions and possess specific market conditions that require particular attention from scholars. Building on the international business and knowledge spillover literature, we examine in the context of emerging economies the channels through which environmental spillovers can take place from manufacturing Multinational Corporations (MNCs) to local companies in the host country. We used data from 24 manufacturing industries in China over the period 2005–2010 to test our contention. Our findings indicate that horizontal (with competitors), backward and forward vertical linkages (with supply chain actors) all had a positive effect on the overall environmental performance of an industry. Moreover, we found that backward industrial linkages (with suppliers) have stronger environmental spillovers than forward (with distributors) and horizontal industrial linkages. Our research contributes to the literature at the intersection of international business and sustainability by unraveling the mechanisms of environmental spillovers in host countries, from the perspective of an emerging economy
Multivariate dependence and spillover effects across energy commodities and diversification potentials of carbon assets
No full textInternational audienceIn a first step, we model the multivariate tail dependence structure and spillover effects across energy commodities such as crude oil, natural gas, ethanol, heating oil, coal and gasoline using canonical vine (C-vine) copula and c-vine conditional Value-at-Risk (CoVaR). In the second step, we formulate portfolio strategies based on different performance measures to analyze the risk reduction and diversification potential of carbon assets for energy commodities. We identify greater exposure to losses arising from investments in heating oil and ethanol markets. We also find evidence of carbon asset providing diversification benefits to energy commodity investments. These findings motivate for regulatory adjustments in the trading and emission permits for the energy markets most strongly diversified by carbon assets
Lesbians’ assessments of gay advertising in France: not necessarily a case of ‘La Vie en Rose?’
No full textInternational audienceThe social, political and economic importance of the lesbian, gay, bisexual and transgender (LGBT) community is increasingly being recognised by what is routinely referred to as mainstream society. However, surprisingly little is known about the nuances of differing behaviour within this broadly defined subpopulation. In a French context, this study examines lesbians’ responses to advertising that is purportedly targeted at them, including ‘gender neutral-implicit’ and ‘gay-explicit’ advertisements. This research furthers previous work by examining ‘in-group’ and ‘out-group’ lesbians’ reactions to (1) gay male-explicit, (2) gay lesbian-explicit and finally (3) gender neutral-implicit advertisements. Further, this research focuses on specific reactions beyond simply ‘attitude towards advertisement’; precisely, an overall ‘evaluation of advertisement’, the ‘ability to generate curiosity’ about the brand, and the ‘degree of likeability of advertisementʼ are compared. It was found that lesbians’ responses to targeted print advertisements were significantly influenced by whether they self-identify with gay males under the holistic banner of ‘gay’. These findings suggest that marketing practitioners would be judicious to stop thinking in terms of one common LGBT advertising target market and start to think about the nuances of homosexual advertising that include (1) response differences to advertising between the ‘G’ market, comprising homosexual men, and the ‘L’ market of homosexual women, and (2) the subtle, but important differences found within the lesbian sub-market
