Noise traders and smart money: Evidence from online searches
2019
International audience; Traditional finance theory considers that the impact of noise traders' attention on asset prices is offset by attention from smart investors. This paper uses online search data to study the influence of noise traders and smart investors on stock returns and volatility. Adopting an original approach, we construct a proxy for smart investor attention based on investors' online search behavior provided by Wikipedia Page Traffic. We combine this new measure with a standard measure of noise traders' attention as proxied by Google Search Volume Index. We show for a sample of 87 French firms over the period 2008–2018 that only noise traders' attention influences stock retur…
Entre indemnisation et effort de reclassement Quel compromis social lors des restructurations ?
2012
National audience; Alors que l’évolution des cadres normatifs va tendanciellement dans le sens d’un dialogue social renforcé, l’observation récente des phénomènes de restructuration en France semble indiquer une recrudescence de la conflictualité. Ce constat, pour autant qu’il soit valide, est porteur de questionnements : le recours au rapport de force constitue-t-il une stratégie préférable à l’identification de solutions négociées ? Peut-on faire un lien entre la forme prise par l’interaction sociale à l’occasion des restructurations et le type de mesures envisagées dans les compromis sociaux ?
Laboratory investigations on co-digestion of energy crops and crop residues with cow manure for methane production: Effect of crop to manure ratio
2007
Abstract Anaerobic co-digestion of grass silage, sugar beet tops and oat straw with cow manure was evaluated in semi-continuously fed laboratory continuously stirred tank reactors (CSTRs). Co-digestion of manure and crops was shown to be feasible with feedstock volatile solids (VS) containing up to 40% of crops. The highest specific methane yields of 268, 229 and 213 l CH4 kg−1 VSadded in co-digestion of cow manure with grass, sugar beet tops and straw, respectively, were obtained with 30% of crop in the feedstock, corresponding to 85–105% of the methane potential in the substrates as determined by batch assays. Including 30% of crop in the feedstock increased methane production per digeste…
Free admission in museums and monuments : An exploration of some perceptions of the audiences.
2008
This paper considers the theme of the audiences' perceptions of free admission in national French museums and monuments. The results show that, from an individual perspective, perceptions of free admission are linked to perceptions of price, money and payment, hence complementing perceptions expressed in a collective perspective (a symbolic, political measure causing either adhesion or rejection). These perspectives are generally put forward by both advocates and opponents of the measure in their discussions. These different visions of free admission have managerial implications for managers of museums and monuments. Copyright © 2007 John Wiley & Sons, Ltd.
La comunicazione istituzionale nelle organizzazioni pubbliche: opportunità e criticità connesse con il corporate brand orientation
2015
Corporate communication in public sector organizations: the opportunities and challenges of a corporate brand orientation. Over the past thirty years, the New Public Management (NPM) has been the dominant approach in the public sector. Leveraging the idea that citizens are customers of the administration, the NPM imports management principles and techniques from the private sector in order to improve the performance of public organizations. After a short description of the main problems associated with the implementation of market orientation in the public sector, this article examines corporate brand orientation as an interesting alternative to market orientation in the public context. Cor…
Current research issues in production economics
2020
This Special Issue includes a selection of papers originally presented and discussed at the Twentieth International Working Seminar on Pro- duction and Operations Management, Innsbruck, February 19–23, 2018, and subsequently extended and improved. Production and Operations Management was established in the1970s as an academic discipline focusing on scientific topics treating the interface between engineering, management, and economics with a special emphasis on financial consequences of decisions in the produc- tion domain. The subject is interdisciplinary in nature and it therefore contains a wide range of topics. The Working Seminar included sessions such as supply chain management, innov…
Designing multi-attribute auctions for engineering services procurement in new product development in the automotive context
2010
Abstract In recent years, use of multi-attribute auctions has been consolidating as a powerful mechanism in procurement settings where multiple drivers affect the transaction outcome. This paper provides a project management approach for multi-attribute auction design for standardized engineering services procurement in the context of new product development in automotive industry. Two variables are taken into account in the bidding process: price and duration of the given engineering activity. From a theoretical viewpoint, we fully determine optimal suppliers’ bidding strategies and expected outcomes, i.e. score/utility, price and duration, for the buyer under both first score sealed bid a…
Risk assessment and profit sharing in business networks
2011
Abstract Nowadays network is the preferred governance form to conduct economic transactions. Network solution allows to reach flexibility maintaining cost and quality level. Since network concept refers to a great variety of organizational hybrids it is possible to choose the one that fits better market requirements. The new trends in inter-organization relationships push towards network solutions: companies are interested in relationships with partners and customers to overcome resource dependence, to enter too risky market or simply differentiate their business portfolio. The proposed research focuses on the network concept aiming at highlighting threats and opportunities to investigate t…
"Facta non verba" : an experiment on pledging and giving
2015
International audience; We design an experiment to investigate whether asking people to state how much they will donate to a charity (i.e., to pledge) increases their actual donation. Individuals’ endowment is either certain or a random variable. We study different types of pledges, namely, private, public and irrevocable, which differ in terms of the cost to the individual for not keeping the promise. We show that in absence of endowment uncertainty, private and public pledges are associated with lower donations as compared to donations in the no-pledge case: private pledges slightly reduce donations and public pledges reduce them more significantly. Donations increase with uncertainty (in…
La valeur du comportement de magasinage. Statut théorique et apports au positionnement de l'enseigne.
2004
Au-delà de la simple fonction d'acquisition de produits, le point de vente apporte au client une valeur à travers sa fréquentation. La typologie des sources de valeur développée par Holbrook est appliquée à la recherche des formes de valorisation de l'expérience de magasinage. Les apports de la valeur du comportement de magasinage à la stratégie de positionnement de l'enseigne sont ensuite explorés à partir d'une étude qualitative.
