Les tensions sur le marché du crédit de trésorerie en France dans une perspective historique
No full textTensions in the French short-Term Loan Market : A Historical Perspective.
This paper assesses the tensions in the distribution of short-term loans in France in 1994-2013. It is hard to determine how much of the decrease in newloanswas due to weaker corporate demand caused by an economic slowdownand howmuch was due to credit rationing by banks. This is a key issue because each scenario calls for different public policy responses. Using a macroeconometric model, we show that tensions appeared in the wake of recessions (1994-1995 and 2009-2010), with a potential for hampering economic recovery. These episodeswere caused by credit supply shocks due to a sharp increase in bad loans amid a rise in credit demand stimulated by a revival of business activity.Cet article analyse les tensions sur le marché du crédit de trésorerie des entreprises en France de 1994 à 2013. Face à la diminution des crédits octroyés, il apparaît difficile de distinguer ce qui relève d’une baisse de la demande de crédit liée au ralentissement de l’activité ou d’une restriction de l’offre bancaire. Cette question est essentielle car les deux situations appellent des réponses différentes en termes de politiques publiques. Les résultats issus d’un modèle macro-économétrique suggèrent que les tensions sur le marché du crédit se manifestent en sortie de récession (en 1994-1995 et en 2009-2010), pouvant alors freiner la reprise économique. Ces épisodes de rationnement tiendraient à une offre restreinte, due à un surcroît de créances douteuses tandis que la demande de crédit progresse sur fond de reprise de l’activité des entreprises.Benhami Kheira, Bessec Marie, Gilquin Guillaume.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Are Economists Chartists or Fundamentalists? A Survey of Eighty French Academics
No full textLes enquêtes auprès des cambistes sur leurs anticipations de change se sont multipliées depuis
une dizaine d’années. En revanche, il n’existe pas d’étude sur la vision universitaire du fonctionnement du marché des changes. Cet article vise à combler cette lacune. Nous avons réalisé en novembre 2002 un sondage au sein de plusieurs universités françaises. 80 chercheurs ont répondu à nos questions. Ils indiquent ne pas croire en une influence des variables fondamentales à court terme. En particulier, ils rejettent l’intérêt pratique de la PPA pour prédire les mouvements des cours. En revanche, les modèles de fondamentaux retrouveraient leur utilité à moyen et surtout à long terme. La confrontation de ces résultats à ceux d’une enquête réalisée sur le marché
des changes américain démontre que ce point de vue est relativement peu éloigné de celui des professionnels du marché.Surveys of market participants are now widely used in the exchange-rate literature. However, there is no study of academics’views on exchange-rate dynamics. Our paper aims to fill this gap. We conducted a survey of 80 economists in several French universities in November 2002. Most respondents do not perceive economic fundamentals as important determinants of exchange rates at short and medium horizons. In particular, PPP is not regarded as a useful concept for predicting exchange-rate movements. The consistency between these beliefs and those of foreign-exchange traders disproves conventional wisdom, which sees a wide gap between the academic view and market traders’ everyday practices.ou
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Étalonnages du taux de croissance du PIB français sur la base des enquêtes de conjoncture
No full textThis paper discusses new bridge models for short-term forecasting of French quarterly GDP growth. The only data used are from business surveys in French manufacturing, services, and construction. We consider two alternative methods. The first relies on the general-to-specific (GETS) algorithm applied to blocks of randomly selected variables (Hendry and Krolzig, 2005) ; the other relies on the combination method popularized by Stock and Watson (2004). We conduct in-sample and out-of-sample assessments of both methods using recursive and rolling regressions. We show that the forecast based on an automatic regression-model selection (GETS) performs better, and that extending the database to business surveys in the service and construction sectors can be useful for short-term GDP forecasting.Cet article développe des nouveaux étalonnages du taux de croissance du PIB français destinés à produire des prévisions de court terme de l’activité . Ils sont construits à partir de données d’enquête de l’Insee, dans l’industrie mais également dans les services et le bâtiment. Nous examinons deux stratégies de réduction de l information, l’une fondée sur l’algorithme de sélection automatique GETS par blocs de Hendry et Krolzig (2005), l’autre sur la méthode de combinaison popularisée par Stock et Watson (2004). Ces deux méthodes sont évaluées en-échantillon et hors-échantillon au travers de régressions récursives et roulantes. Nous montrons la supériorité des étalonnages construits avec GETS et l’intérêt de considérer d’autres enquêtes que celle dans l’industrie dans les stratégies de modélisation et de prévision.Bessec Marie.

koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
