Robust Lot-sizing and Supplier Selection under Lead Time Uncertainty
No full textAbstract book, voir url dans champ "Voir aussi"International audienceWe study the single item lot-sizing problem with supplier selectionand uncertain lead time. We consider the situation where a companyhad preselected a set of suppliers for an item, and these suppliers havedifferent prices, different lead times, but also different reliability. Weaim to provide a robust optimization approach to decide when to order,how much to order, and from which suppliers, in the context of un-certain delivery lead time. We formulate the robust optimization prob-lem with polyhedral budgeted uncertainty sets. This formulation doesnot require assumptions on order crossovers, order splitting, or on thestructure of the demand or lead times. We propose an exact row andcolumn generation algorithm to solve the considered problem, alongwith some enhancements including a fast cut generation procedure. Toimprove the scalability of the approach we propose several heuristics,including a hybrid of the robust counterpart reformulation and row andcolumn generation, and a fix-and-optimize approach in the row andcolumn generation framework. Experimental results show that the fix-and-optimize approach provides good results. Finally, we provide in-sight into the reaction of the decision-maker to unreliable suppliers.One of the conclusions is that in the considered framework, an ex-tremely risk-averse decision-maker selects a single supplier, namelythe most reliable one even if it does not offer the lowest price
Institutional environment, the ultimate controller's characteristics and CSR disclosure in China
No full textInternational audienceUsing a dataset of Chinese listed companies from 2009 to 2018, this study empirically examines the relationship between a company's institutional environment, the ultimate controller's characteristics and its level of corporate social responsibility (CSR) disclosure in China. The results show that Chinese companies operating in better institutional environments have higher CSR disclosure. Moreover, the type of the ultimate controller of a company is significantly related to the level of CSR disclosure, which is higher in state-controlled companies than in nonstate-controlled companies. The results are robust to different proxies of CSR disclosure
From Policy-Practice to Means-Ends Decoupling in Organizations: A Systematic Review and Paths for Future Research
No full textInternational audienceRecent developments in the innovation literature suggest that even when an organisation truthfully implements the adopted R&D policy, it may still fail to achieve its intended goals, a phenomenon called means-ends decoupling. We employ a systematic literature review to answer the question of "what is the current state of knowledge in the phenomenon of means-ends decoupling in the literature" and "where it can move in the future". Our paper provides a framework that delineates means-ends decoupling from policy-practice decoupling and identifies the underlying mechanisms that explain when and how means-ends decoupling may occur within an organisation's activities
Corporate social responsibility and firm market performance: the role of product market competition and firm life cycle
No full textInternational audienceThis study empirically investigates the role of product market competition and mature-stage firm life cycle on the relation between corporate social responsibility (CSR) and market performance in an emerging market context – Malaysia. The authors construct a comprehensive CSR index toward the economy, environment and society (EES) and apply both Ordinary Least Squares (OLS) and Two-Stage Least Squares (2SLS) instrumental variables (IV) approaches to test the hypotheses of the study. The authors find that EES-based CSR generally enhances firms' market performance; however, the level of product market competition undermines the market performance of socially and economically responsible firms. In addition, the study results indicate that mature-stage firm life cycle with more involvement in CSR activities shows better market performance. However, the endogeneity check of CSR suggests that both CSR and mature-stage firms are mutually exclusive in influencing market performance. The study findings are robust to alternative measures and different identifications of high and low default risk situations of sample firms. Practical implications This study carries practical policy implications for the listed firms, regulators and stakeholders in general. For example, regulatory bodies may promote greater involvement in CSR activities by listed companies in the Malaysian stock market. Investors and other market participants should be aware of factors influencing socially responsible firms' market performance such as the corporate life cycle and the level of competition in product markets. This research work responds to the call of regulatory bodies in Malaysia at a time when the Malaysian economy is under threat of environmental distraction practices by the palm oil industry and import ban by the largest export market, i.e. the European Union by 2030. The study also contributes to the theoretical literature by refining the moderating role of product market competition and mature-stage life cycle on the relationship between CSR and market performance from the perspectives of resource-based and stakeholder theories in emerging economy settings
Foreign and domestic multinationals’ linkages in advanced, small open economies: do foreignness, regional origin and technological capability matter?
No full textInternational audiencePurpose International business theory suggests that multinational enterprises (MNEs) seek to internalise resources embedded in local firms to complement their own through inter-organisational relationships, yet little is known about whether and how these business linkages differ between foreign (F)MNEs and domestic (D)MNEs. This paper aims to explore the linkage differential between DMNEs and FMNEs operating in the same single-country contexts and to examine whether foreignness, regional origin and technological capability make a difference. Design/methodology/approach This study is based on a unique firm-level data set of 292 MNEs located in five advanced, small open economies (SMOPECs). This study analyses the benefit received – in the form of technical and organisational resources and knowledge – by DMNEs and FMNEs via backward, forward and collaborative linkages with local business partners. Findings Our research finds FMNEs benefit less from linkages than DMNEs; and FMNEs originating from outside the region especially so. However, the results also show technological capability mitigates this difference and is thus a game changer for FMNEs from outside the region. Originality/value This paper differentiates between FMNEs and DMNEs in their propensity to benefit from resources received from different local partners and explores the influence of regional origin and technological capability. Despite the advanced and internationally oriented nature of SMOPECs, DMNEs still gain more benefit, suggesting either liabilities of foreignness and outsidership persist, or FMNEs do not desire, need or nurture local linkages

Interaction Effects in Cross-Lagged Panel Models: SEM with Latent Interactions Applied to Work-Family Conflict, Job Satisfaction, and Gender
No full textInternational audienceResearchers often combine longitudinal panel data analysis with tests of interactions (i.e., moderation). A popular example is the cross-lagged panel model (CLPM). However, interaction tests in CLPMs and related models require caution because stable (i.e., between-level, B) and dynamic (i.e., within-level, W) sources of variation are present in longitudinal data, which can conflate estimates of interaction effects. We address this by integrating literature on CLPMs, multilevel moderation, and latent interactions. Distinguishing stable B and dynamic W parts, we describe three types of interactions that are of interest to researchers: 1) purely dynamic or WxW; 2) cross-level or BxW; and 3) purely stable or BxB. We demonstrate estimating latent interaction effects in a CLPM using a Bayesian SEM in Mplus to apply relationships among work-family conflict and job satisfaction, using gender as a stable B variable. We support our approach via simulations, demonstrating that our proposed CLPM approach is superior to a traditional CLPMs that conflate B and W sources of variation. We describe higher-order nonlinearities as a possible extension, and we discuss limitations and future research directions
Financing green technology development and role of digital platforms: Insourcing vs. outsourcing
No full textInternational audienceThis paper investigates the green technology development (GTD) problem of a capital-constrained manufacturing entrepreneur who seeks financial support from external and internal multi-sided platforms (MSPs). Following the government's environmental policies, MSPs (i.e., outsourcing and insourcing alternatives) determine their strategies and offer platform-driven solutions to the manufacturing entrepreneur pursuing green innovation. Using benchmark models, we first analyze decisions made by the manufacturing entrepreneur and the MSP under the deregulated scenarios. We then develop a three-level game-theoretical model and sequentially characterize the decision-making behavior of players under three platform power structures. The model outcomes are compared by considering the government's policymaking approach and platforms' power structure. Results reveal that, when coupled with appropriately designed trade-credit and revenue-sharing mechanisms and the government's innovation-based social welfare approach, the internal MSP system always outperforms the external alternative. Our study demonstrates that a win-win agreement among GTD players can only be achieved if the MSPs take the balance of power and remain committed to empowering the initiated sustainable ecosystem. In power struggle scenarios, however, GTD players prioritize the internal MSP over the external MSP. To fulfill the GTD goals, players are encouraged to use their structural and legislative power and adjust their strategies, investment decisions, and power preferences accordingly
Does Target Country Cultural Orientation Influence M&A?
No full textInternational audienceWe examine whether the cultural orientation of target firms influences the outcomes of international mergers and acquisitions (M&As). Prior research shows that the national culture of the acquiring firm country influences M&As, as well as the distance between the acquiring and target country cultures. Not previously studied from a cultural perspective of M&As has been the target country culture, despite estimates that about 40% of M&As are target-initiated. Our focus is on target firm cultural orientation, including how cultural orientation affects the likelihood of, and returns from, M&As. Our testing applies three cultural orientation factors (results, tradition and people orientation) extracted from a GLOBE cultural framework to a dataset of firm-level M&A data across 39 countries, in 1990–2016. We find that firms from cultures with a results orientation are less likely to become M&A targets and also experience higher cumulative abnormal returns if acquired, while firms from countries with cultures with a tradition orientation or a people orientation are more likely to become targets but experience lower cumulative abnormal returns if acquired. These results are robust to a comprehensive range of robustness tests. Our findings suggest that understanding the cultural orientation of target firms is important to understanding M&A outcomes
Fast Fashion, Charities, and the Circular Economy: Challenges for Operations Management
No full textInternational audienceTextile waste is one of the most pollutant items globally, being strongly affected by fast fashion (FF) products. Public pressure has made many FF firms voluntarily collect a small fraction of their preowned items and export them to developing countries for reuse. However, some developing countries are launching import bans on second-hand clothes. In addition, FF firms may soon be forced by extended producer responsibility legislation to collect more preowned items for reuse and recycling. To date, they do not have sufficient capacity to deal with this. Charities have been the key collectors and recyclers of unwanted clothes. Therefore, charities could help FF firms increase their capacity in this reverse supply chain (SC). However, we hardly witness such a collaboration for two main reasons: (i) charities prefer to sell high-quality preowned items in the primary market to generate the highest possible revenue and FF firms may fear cannibalization, (ii) many charities believe that FF firms generate quantities of low-quality items that require collection and sorting while being difficult to sell in the primary market. Charities also face competition from many small for-profit organizations selling FF preowned items. While charities have the support of volunteers, they tend to be less efficient. This work urges Operations Management (OM) researchers to suggest innovative business models to help (i) FF firms and charities collaborate to solve the abovementioned issues, and (ii) charities to improve their traditional practices for competitiveness. This study is primarily a position paper highlighting some challenges and introducing interesting research problems. Although the paper is not a research paper, it follows a qualitative research method to collect and analyze the required supporting documents to justify arguments and statements. We collected primary and secondary data from the textile reverse SC members to familiarize the OM community with this context. The current changes in the textile reverse SC offer many great opportunities for impactful OM research
