Impact of foreign ownership on market power: Do regional banks behave differently in ASEAN countries?
No full textInternational audienceThe change in crossborder financial intermediation and rise in regional banking have consequences for competitive conduct in emerging countries' banking markets. Using data from the Association of Southeast Asian Nations countries' banks during 2011–2018, we examine the nexus between foreign ownership and banks' market power by controlling for the heterogeneity of foreign banks concerning their countries of origin (advanced vs. emerging and regional vs. nonregional). We find that the increasing presence of foreign banks from advanced countries is associated with lower bank market power because of higher marginal costs and lower price–cost margins of the domestic banks. However, the increasing presence of emerging countries’ banks is associated with higher bank market power because of lower marginal costs and prices of domestic lenders. Our findings have implications for policies regarding bank competitiveness and promoting regional banking integration because domestic banks conduct differently under increased participation levels of advanced and emerging country foreign banks
Mobilizing suppliers when starting up a new business venture
No full textInternational audiencePrior research has shown that new ventures can complement their capabilities and extend their limited internal resources by drawing on suppliers. Yet, our knowledge of the supplier mobilization process in new ventures is limited. In this paper, we take a relational perspective on the mobilizing process, which entails investigating the scope for mobilizing suppliers in new ventures and new ventures' attractiveness to suppliers. Drawing on three new venture cases, we posit that for new ventures the scope for mobilizing suppliers: 1) ranges from the use of suppliers for the procurement of well-defined existing inputs to the co-development of various resources and capabilities with suppliers; 2) varies across ventures, reflecting the new venture's distance to market; and 3) depends on the supplier's assessment of the new venture's attractiveness as a customer. We also argue that the attractiveness of new ventures as customers to the suppliers is based on elements that differ from those found in studies of ongoing businesses, and include: 1) stimuli to innovate and develop new competencies, 2) reputational benefits and prestige, and 3) personal satisfaction
A legitimacy perspective on sharing economy consumption in the accommodation sector
No full textInternational audienceThis research adopts a consumer focus in examining the impact of perceived legitimacy of sharing economy platforms on attitude and behavioural intention in the accommodation sector. By investigating tourist adoption of sharing economy platforms from a legitimacy perspective, this research differs from past studies which focused on characteristics of new services to predict adoption. Results show that (1) tourists evaluate legitimacy through comparisons with traditional offers in the accommodation sector rather than with other sharing economy offers, (2) lack of legitimacy has a negative effect on guest behavioural intentions and (3) this effect is moderated by relativism. Even though sharing economy platforms' commercial success may imply that they are enjoying a high level of legitimacy in the eyes of tourists, our results suggest that tourists act as societal actors and that the legitimacy issues raised by the sharing economy are relevant to them and inform their decisions
Gender diversity in boardrooms and corporate financial performance: Evidence from the male-dominated society of Qatar
No full textInternational audienceThis study examines the relationship between board gender diversity and the corporate financial performance (CFP) of companies listed on the Qatar Stock Exchange. We use the ordinary least square (OLS) regression as the baseline technique along with the system GMM generalized method of moments (GMM) approach to mitigate the possible issue of endogeneity. Our analysis reveals that board gender diversity negatively affects CFP. Our findings are robust to the use of alternate measures of board gender diversity and free from endogeneity concerns as demonstrated by the results of the system GMM regression estimates. Further, we explain the possible reasons of this negative relation, particularly in the context of Qatar. An important implication of our findings is that they identify the factors that inhibit the women in Qatar from making significant contributions to board proceedings as well as to CFP in its male-dominated society
Ethical leadership and environment specific discretionary behaviour: The mediating role of green human resource management and moderating role of individual green values
No full textInternational audienceThis study examines the mediating role of green human resource management between ethical leadership and employees' citizenship behavior towards the environment with the moderating effect of individual green values. We collected data from 589 MBA executive students with one-year of experience working in various organizations at two different times using a questionnaire-based survey method. Applying structural equation modeling to the results confirmed a direct effect of ethical leadership on employees' citizenship behavior towards the environment and an indirect effect through green human resource management. Further, individual green value strengthened the association between green human resource management and employees' environmentally conscious citizenship behavior. Our study contributes to social learning and supply value-fit theory and has implications for management
“Shiny” crypto assets: A systemic look at gold-backed cryptocurrencies during the COVID-19 pandemic
No full textInternational audienceIn this paper, we empirically analyse the performance of five gold-backed stablecoins during the COVID-19 pandemic and compare them to gold, Bitcoin and Tether. In the digital assets' ecosystem, gold-backed cryptocurrencies have the potential to address regulatory and policy concerns by decreasing volatility of cryptocurrency prices and facilitating broader cryptocurrency adoption. We find that during the COVID-19 pandemic, gold-backed cryptocurrencies were susceptible to volatility transmitted from gold markets. Our results indicate that for the selected gold-backed cryptocurrencies, their volatility, and as a consequence, risks associated with volatility, remained comparable to the Bitcoin. In addition, gold-backed cryptocurrencies did not show safe-haven potential comparable to their underlying precious metal, gold
Value creation and appropriation of software vendors: A digital innovation model for cloud computing
No full textInternational audienceDo software vendors propose, create, and capture value in the era of digital transformation? Drawn on the literature of business models, digital innovation, and firms' capabilities, we examine this cutting-edge research question. We conducted a multiple case research of 10 software vendors operating in Germany and Austria. The thematic analysis yields a conceptual model that explains whether and how software vendors leverage cloud computing-enabled innovation for the digital boost, which is this study's primary contribution to information systems research. Software vendors use a complementary portfolio of information technology and organizational capabilities to innovate in their value proposition, creation, and capture
Designing Bioenergy Supply Chains Under Social Constraints
No full textPart 6: Meta-Heuristics and Optimization Techniques for Energy-Oriented Manufacturing SystemsInternational audienceThe use of renewable energy, as a clean alternative to fossil fuel, has become very attractive. It has environmental advantages and leads to regional development. This study proposes an optimization model for the design of bioenergy supply chains under social concerns. The social concerns involve the unemployment rate and the vulnerability to changes during an economic crisis.The areas that are mostly exposed to these social issues are chosen as initial potential locations for installing the biorefineries. Installing a biorefinery can generate jobs for the people of these areas. This leads to the sustainable development in the areas. The applicability of the developed model is shown through a case study. The results demonstrate that the proposed approach leads to the generation of a large number of job positions which has an important impact on the social development of these regions
Performance implications of export assistance: the mediating role of export entrepreneurship
No full textInternational audienceAlthough both institutional export assistance and entrepreneurial orientation (EO) contribute separately and positively to export performance, the interplay between them has received little attention. This study examines the role of international EO in deriving performance benefits from governmental and nongovernmental export assistance
Lessons from Applying Sanctions and Blockades
No full textInternational audienceFrom the geo-economic standpoint, a power may avail itself of a spectrum of constraining measures against a hostile or dangerous nation - measures ranging from sanctions, boycotts to embargos and blockades, which last represent the ultimate form of economic pressure to which an adversary may be subjected. Because they are an extreme type of economic banishment, their imposition reveals the physiognomy of the power struggle; and, because they obstruct the free flow of goods, they also appear to be an ephemeral anomaly within the Liberal world order. Yet, their incumbency in the game is a reflection of geo-economic complexity. Whether enacted to great fanfare or not, blockades freeze some transactions while generating business opportunities elsewhere. And while an activity momentarily stilled in one zone may be reshaped to the advantage of another, blockades still allow their instigators to zero in on key sectors of the enemy's economy without endangering the country's survival. Thus, we can see blockades as an economic and military measure serving imperial ends. This essay succinctly reviews the history of famous blockades and garners the core economic lessons one may learn from them
