Investisseurs étrangers et asymétries d'information : l'impact de la structure de propriété des entreprises chinoises sur la composition des syndicats bancaires
No full textLes entreprises chinoises ont connu des réformes importantes depuis le début des années 1990. Ces réformes associées au potentiel de croissance de l’économie chinoise ne manquent pas d’attirer les investisseurs étrangers. Cependant, les risques d’un investissement demeurent élevés du fait d’un environnement juridique et financier faiblement protecteur des investisseurs. L’investissement en Chine suppose donc une connaissance fine du fonctionnement des entreprises locales, des conventions juridiques, voire même de la culture sociale du pays. De ce fait, un investisseur étranger peut souffrir d’asymétries d’information par rapport à son homologue local. Ce mémoire étudie la façon dont les banques étrangères résolvent les problèmes d’asymétries d’information dans leur politique de prêt en Chine au travers du marché des prêts syndiqués. Le marché des prêts syndiqués présente notamment l’avantage de garantir la présence de banques étrangères du fait de son caractère international, et de permettre d’étudier les asymétries d’information à partir de la structure des syndicats bancaires
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
Can better capitalised banks be more profitable? An analysis of large French banking groups before and after the financial crisis
No full textThe article studies the effect of French banks’ capitalisation on their profitability. It contributes to the debate which has emerged, following the financial crisis, on the impact of the tightening of the regulation of capital (Basel III). Our econometric results show that over the period of 1993-2012, beyond the general trend of profitability which is weaker after the crisis, banks which increase their capital ratio more than the average improve their profitability, without it being possible to distinguish between voluntary increases and those imposed by regulation. All else being equal, a 100 basis point increase of the different capitalisation measures leads to a 3 to 10% increase in the average return on equity (ROE), depending on the measures considered, and to a 7 to 30% increase in the average return on assets (ROA). The positive impact of an increase of capitalisation on ROA is less significant when it is done by issuing shares.De Bandt Olivier, Camara Boubacar, Pessarossi Pierre, Rose Martin.

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
Essais sur le système financier chinois
No full textThis dissertation analyzes the development of the Chinese financial system from different perspectives. It has shed light on the recent advancements of the last decade. Overall, the findings reveal a contrasted picture of the progress achieved towards an efficient system. Chapter 1 has shown that the corporate bond market is still impeded by government influence. Based on this evidence, it is thus very unlikely to expect the banking system to decrease its dominance on the financial system. Chapter 2 also stressed that internal governance mechanisms remain imperfect. By analyzing the market price fluctuations at the time of the announcement of a CEO turnover, we find that ownership type plays a major influence on the expected consequences of such a decision. Chapter 3 revealed that little progress has been made in terms of banking competition despite the increasing number of new entrants in the market. However, banks behaved more efficiently over the decade. No trade-off seems to exist for policy-makers between the benefits of lower banking prices and efficiency of the system. Chapter 4 finally showed the beneficial effects of the capital requirement regulation on bank efficiency in China. Capital requirements, in supplement to provide higher capital buffers, appear to lower moral between banks’ shareholders and debtholders.Cette thèse étudie le développement du système financier chinois. Elle dévoile des aspects nouveaux du développement du système financier sur la dernière décennie. Globalement, les résultats montrent que les progrès réalisés vers un système efficient demeurent contrastés. Le premier chapitre montre que le marché obligataire des entreprises non financières est toujours sous influence du gouvernement. Sur la base de cet élément, il est peu probable d’espérer une baisse de la domination du secteur bancaire sur le système financier. Le second chapitre montre que la gouvernance d’entreprise interne reste imparfaite. En analysant les fluctuations des prix des actions au moment de l’annonce d’un changement de P-DG, nous trouvons que le type de propriété de l’entreprise joue une influence majeure sur les conséquences d’une telle décision. Le troisième chapitre révèle que peu de progrès ont été faits en termes de concurrence au sein du secteur bancaire malgré le nombre de nouveaux entrants sur le marché. Cependant, les banques se comportent de façon plus efficiente sur la décennie. Il ne semble pas exister d’arbitrage entre les bénéfices d’une plus grande concurrence et l’efficience du système bancaire en Chine. Le quatrième chapitre montre les effets bénéfiques de la nouvelle réglementation sur les exigences en capital des banques chinoises en termes d’efficience bancaire. Les exigences en capital, en plus de fournir des coussins en capital supplémentaires, apparaissent réduire l’aléa moral entre les actionnaires des banques et leurs créanciers
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
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
