Evaluation de l'impact médico-économique et social du programme OIIS, rapport méthodologique, projet régional OIIS.
No full textCe rapport méthodologique a pour objectif de présenter le processus d'évaluation envisagé pour le programme OIIS, Océan Indien Innovation, dans le cadre du programme Territoire de Santé Numérique (TSN). Il présente à la fois les concepts théoriques sous-jacents issus des travaux de recherche en mesure d'impact social (notamment le SROI, retour social sur investissement, mesuré par un ratio des impacts sur les contributions) et des travaux en économie de la santé relatifs à l'évaluation médico-économique. La priorité est accordée aux différentes parties prenantes du programme et à leur implication dans l'évaluation. Cela se traduit par une participation des différentes parties prenantes à des formations de sensibilisation aux méthodes d'évaluation retenues et à leur contribution dans la co-construction des indicateurs pertinents. Le but ultime de la méthode est d'aboutir à une mesure d'impacts socio-médico-économiques afin de proposer un ou des modèles économiques pertinents et assurant la pérennité du programme. Toute la démarche étant co-construite, partagée, progressive, les résultats obtenus du programme seront dans tous les cas positifs en terme d'implication des acteurs de la santé, aussi bien professionnels que patients, de l'Ile de la Réunion
Nominal income versus Taylor-type rules in practice
No full textSince the beginning of the financial crisis, a lively debate has emerged regarding which monetary policy rule the Fed (and other central banks) should follow, if any. To clarify this debate, several questions must be answered. Which monetary policy rule best the historical data? Which monetary policy rule best minimizes economic uncertainty and the Feds loss function? Which rule is best in terms of household welfare? Among the different rules, are NGDP growth or level targeting rules a good option, and when? Do they perform better than Taylor-type rules? To answer these questions, we use Bayesian estimations to test the Smets and Wouters (2007) model under nine different monetary policy rules with US data from 1955 to 2015 and over three different sub-periods. We find that when considering only the central bank’s loss function, the estimates generally indicate the superiority of NGDP level targeting rules, whatever the period. However, if other criteria are considered, the central banks objectives are not consistently met by a single rule for all periods
Design Science Research Contribution to Business Intelligence in the Cloud – A Systematic Literature Review
No full textInternational audienceBusiness intelligence (BI) helps managers make informed decisions. In the age of big data, BI technology provides essential support for decision making. Cloud computing also attracts many organizations because of its potential: ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications, and services). This paper focuses on the deployment of BI in the cloud, from the vantage point of design science research (DSR). We produce a state of the art of research pertaining to BI in the cloud, following the methodology of systematic literature review. This literature review especially exhibits the different artifacts proposed by design science researchers regarding BI in the cloud. To structure the literature review, we propose a framework composed of two dimensions: artifact type and BI step. In particular, we propose a typology of artifact types, refining the coarse-grained typology commonly used in DSR. We use the two-dimensional framework both to map the current state of DSR regarding BI in the cloud, and to elicit future research avenues in terms of design science artifacts for BI in the cloud. The contribution is threefold: the literature review may help DSR researchers get an overview of this active research domain; the two-dimensional framework facilitates the understanding of different research streams; finally, the proposed future topics may guide researchers in identifying promising research avenues
Trois essais sur les fusions-acquisitions transfrontalières
No full textCompared to domestic M&A, the literature of cross-border M&A is relatively fewer. Most of the current research is based on US studies. We also have much less knowledge about the cross-border M&A from developed countries to emerging countries. Motivated by the general research background, the thesis conducted three distinctive papers regarding cross-border M&As from European Union (EU) to emerging countries. We propose three research questions that are seldom addressed in previous literatures: 1) Does industrial diversification explain the cross-border M&A from the European Union to emerging countries? 2) Do market value industrial specialization or diversification in CBM&A with emerging countries? 3) Do acquiring managers take advantage of the market timing in payment decisions in CBM&A with emerging countries? In addition, we compared the CBM&As with those of domestic France as well as the CBM&As inside the European Union. Based on 2406 fusions-acquisitions in France, 7628 CBM&As inside the European Union, and 1857 CBM&As between European firms and the emerging markets during 1992-2012, we find the following results. First, consistent with what is observed in prior M&As literatures between companies in developed countries but contrary to what is suggested in the theoretical arguments in earlier literatures about emerging countries, we show CBM&As from the European Union to emerging countries are industrially specialized rather than industrially diversified. We find that there is a negative relationship between international diversification and industrial diversification. Second, we found that the announcement effects for CBM&As between the E.U.-15 and emerging market are positive, but compared to CBM&As conducted wholly inside the E.U.-15 and domestic M&As in France, they are significantly less positive due to the focus on industrial diversification versus specialization. Third, we found the market undervalues the acquiring firms in CBM&A from the European Union to emerging countries. The acquiring managers do not take the advantage of the market timing when making their payment decisions. Our results show the acquiring firms do not incline to pay cash in CBM&A to emerging countries but rather in CBM&A inside European Union. In the meanwhile, we find the premium paid by the acquiring firms are not different from CBM&As inside the European Union. Our analyses evidence that acquiring firms are reluctant to pay cash in CBM&As with emerging countries. The thesis contributes to the current M&A empirical literatures and it has provided important research implications. It highlights also that there are clear conflicts of interests between investors and managers in the cross-border from the European Union to emerging countries. The thesis also opens new perspectives for the future research. For example, we observed that industrial diversification has an increasing trend in recent years, and it is valued positively by the market. We believe the results may be attributable to either the financial crisis or the better integration of emerging markets into the world economy.Par comparaison avec la littérature sur les fusions-acquisitions nationales, celles sur les fusions-acquisitions transfrontalières (Cross-Border Mergers & Acquisitions, CBM&A) est relativement récente. En particulier, nous avons encore très peu d’études sur les fusions-acquisitions entre les entreprises des pays développés et émergents. Cette thèse considère trois questions rarement abordées jusqu’à présent. 1) Est-ce que la diversification industrielle peut expliquer les fusions-acquisitions entre les entreprises européennes et des marchés émergents? 2) Est-ce que le marché valorise plus dans ces opérations les actions de diversification industrielle? 3) Quelles sont les modalités de paiement préférées dans ce type d’opérations ? Parallèlement, nous avons comparé ces opérations de fusions-acquisitions à celles ayant lieu en France et à l’intérieur de l’Union Européenne. Fondés sur 2406 fusions-acquisitions en France, 7628 à l’intérieur de l’Union Européenne et 1857 entre des entreprises européennes et des marchés émergents sur la période 1992(1998)-2012, nos résultats sont les suivants. Premièrement, conformément à ce qui est observé dans les fusions-acquisitions entre des entreprises des pays développés mais contrairement à ce que laisse entendre la littérature théorique sur les investissements dans les marchés émergents, les fusions-acquisitions entre les entreprises européennes et de pays émergents sont plutôt des opérations de spécialisation industrielle. Nous constatons également que la relation entre la diversification internationale et la diversification industrielle est négative. Deuxièmement, les effets d'annonce des CBM&A entre les pays de l’'Union Européenne et les marchés émergents se traduisent par une augmentation de richesse des actionnaires des entreprises européennes acquéreuses. Cependant, par rapport aux fusions et acquisitions réalisées entièrement à l'intérieur de l'Union Européenne et en France, les effets d’annonces sont beaucoup moins positifs. Troisièmement, les marchés financiers sous-évaluent les entreprises européennes lors des fusions-acquisitions avec des entreprises de pays émergents. Nos résultats démontrent que les entreprises acquéreuses payent moins en espèces dans les fusions-acquisitions avec des entreprises des marchés émergents qu’avec d’autres entreprises européennes. En revanche, les primes payées ne sont pas significativement différentes. Nos résultats suggèrent aussi que les dirigeants des entreprises Européennes ne jouent pas sur le « market timing » lors de leurs décisions de paiement. Cette thèse a des implications importantes pour des futurs acquéreurs d’entreprises de pays émergents. Compte tenu des résultats obtenus sur la fin de notre période d’analyse, elle révèle que la diversification industrielle dans les fusions et acquisitions d’entreprises de pays industrialisés avec des entreprises de marchés émergents est plus importante ces dernières années, et qu’elle a un impact positif. Nous pensons que les résultats peuvent être attribuables soit à la crise financière soit à une meilleure intégration des marchés émergents dans l'économie mondiale. Elle met aussi en évidence qu'il existe des conflits d'intérêts clairs entre les investisseurs et les dirigeants lors de fusions-acquisitions entre des entreprises européennes et de pays émergents
Disclosure strategies and investor reactions to downsizing announcements: A legitimacy perspective
No full textInternational audienceIn this paper, we focus on a relatively underexplored aspect of sustainability—workforce reductions. We investigate the determinants and consequences of the decisions made by French firms to use press releases in order to announce downsizing operations. We also examine whether the content of press releases has an impact on investor reactions to downsizing announcements. Particularly in the French context, downsizing operations reflect negatively on corporate social responsibility with respect to employees, and we anticipate that French managers will use disclosure strategies to counter a potential legitimacy threat. Our sample consists of 227 downsizing operations announced between 2007 and 2012 by 119 French listed firms. We find that the disclosure of press releases is driven by both contextual and legitimacy factors. We also find that press releases are associated with more negative reactions to downsizing announcements than when there is no press release, particularly in the case of proactive operations (i.e., implemented by firms with improving performance). A content analysis of press releases indicates that firms, on average, engage in a reactive impression management strategy in their disclosure that consists of attributing downsizing operations to external factors. Moreover, investors penalize the use of proactive arguments, particularly when they are used to justify proactive operations. Overall, our results show that, in the French case, disclosure strategies and their consequences on the financial markets relate to a legitimacy perspective
