Patient preferences, referral process, and access to specialized care. Is patient choice constrained?
No full textInternational audienceIn most developed countries, patients have been encouraged to elect their preferred choice of health care provider. However, this is different for specialized care, where the patient’s referral could be defined as a two-stage decision process and their options are pre-selected by their general practitioner (GP). In this study, we estimate patient preferences while controlling for the pre-selection procedure, and we investigate whether patients are actively choosing their provider for cancer care. The French national hospital discharge database (Programme de Médicalisation des Systèmes d’Information, PMSI – MCO 2017) has been used for investigation. We estimated a multinomial choice model when choice sets are in fact unobserved, which is assumed to identify patient preferences, in a revealed preferences framework. Our findings provide evidence that patients consider factors other than distance to select their provider. The patient – hospital distance as well as the specialization profile of providers appears to be internalized in the pre-selection process, while patients rather consider waiting times, hospital quality, and other provider attributes to make their final choice. We also found that patients would be treated in higher-quality hospitals if they had the opportunity to choose among all available providers
Peer effects in an automated world
No full textInternational audienceBeyond its technological impact, automation also transforms the social context of the workplace by weakening peer effects. We study the often-neglected effects of this transformation on work production. Using experiments in which people complete a sequential task, we show that humans who work with algorithms underperform those who work with other humans, especially when workers are rewarded under team incentives. Our findings stress that firms should account for the weakening of peer effects due to automation when assessing the cost-efficiency of replacing humans with algorithms.<br/

BRICs & clicks : Insights into the sociomateriality of consuming social networking sites
No full textInternational audience"Cette recherche aborde le problème du manque de recherches comparatives sur la consommation des réseaux sociaux et le comportement des internautes dans les “BRIC” (Brésil-Russie-Inde-Chine). Des données sont recueillies auprès d’individus à l’aide d’une enquête et d’entretiens afin d’identifier les différents types de comportement des internautes, pour développer un modèle de la culture numérique qui montre les effets du contexte culturel sur le contexte sociomatériel, et la manière dont ces facteurs peuvent être employés pour expliquer le comportement des internautes. Les résultats donnent une vision contemporaine qui peut informer les entreprises qui opèrent sur ces marchés afin d’exploiter l’interactivité numérique.""This study addresses the lack of comparative research on the consumption of social networking sites (SNS) and SNS user behaviour in four emerging economies: Brazil, Russia, India, China. Using online survey and interviews, data are collected from individuals in order to identify different types of SNS user behaviour. From the findings, we develop a simplified framework of digital culture to show the effects of BRIC cultural context on sociomaterial context, and how these factors can be used to explain SNS user behaviour. The findings offer contemporary insights that can inform businesses operating in BRIC markets for leveraging digital interactivity"<br /
Navigating investment decisions with social connectedness : Implications for venture capital
No full textInternational audience"This study examines how the geographical structure of social networks shapes venture capital (VC) investment decisions. We find that VC firms invest more in portfolio companies in socially connected regions. The effect is more pronounced among independent, smaller, less reputable, early–stage–focused VC firms and those not from a VC hub. We further document that social connectedness lowers the likelihood of a successful exit since it induces VC firms to undertake suboptimal investment decisions. Overall, our findings highlight the role of social connectedness in constituting the geographical differences in VC firms’ capital allocation and investment outcomes."<br /
How do omnichannel strategies contribute to value-based healthcare? : An orchestra-based analysis
No full textInternational audience"The healthcare ecosystem is currently characterized by multiple interactions at different levels that call for new managerial approaches in line with value-based healthcare, where the omnichannel strategy is crucial. Drawing on the omnichannel approach in the B2B context, the overall objective of the current study is to unveil the underlying mechanisms through which a healthcare organization can transform the value creation process within its business ecosystem. An in-depth case study of an ecosystem has been used to demonstrate how the design and development of digital solutions can provide better services to the different agents involved in the healthcare sector. Our results show how an orchestra model of an innovation ecosystem effectively works and reveal the orchestration mechanisms operating in the healthcare industry, drawing on the example of the Patient Support Program (PSP) provider as the orchestrator. Moreover, key challenges have been highlighted, and the role of B2B marketing has been identified as crucial, providing important implications for managers and scholars."<br /
Multi-echelon Urban Distribution Networks: Models, Challenges and Perspectives
No full textInternational audience"This chapter presents two-echelon location and routing models and discusses their characteristics and solvability. It describes new paradigms in urban logistics and their challenges related to governance, green logistics, smart cities, and hyperconnected logistics. Designing distribution networks has critical impacts for city logistics stakeholders on cost, revenue and service levels to the city citizens. Using mathematical models to design the optimal distribution network is particularly constrained by the characterization of the operating environment and multiple factors such as demand, product portfolio, inventory levels, response time and returnability. The chapter focuses on the routing approaches dedicated to cargo bikes as this one is among the fastest-growing delivery modes in urban areas. A special emerging problem that challenges urban distribution and fits into the two-echelon setting is omnichannel retailing. The major challenge for cities and operators lies in the positioning of the transshipment and the resulting logistics organization: upstream for their supply, and downstream for delivery to customers."<br/
