Bank liquidity and performance in Basel 3
No full textThe paper assesses, on the basis of available data and simplified hypothesis, the value of the Net Stable Funding Ratio on a sample of top-tier international banks operating in five area of specialization (Bank Holding & Holding Companies, Commercial Banks, Cooperative Banks, Saving Banks and Real Estate & Mortgage Banks) both in the pre-crisis period (2005-2007), and in the crisis and “post” crisis period (2008-2009), in order to identify which sample banks comply with new structural liquidity risk measure on the dual time horizon considered. The results highlight that the banks with structural liquidity furthest away from minimum requirements are those that would probably be included in the systemic risk list drawn up by the Group of Governors and Head of Supervision, belonging to the category of Bank Holding & Holding Companies or Commercial Banks. Conversely, the sample banks with liquidity structures in line with the new liquidity requirement NSFR are those belonging to the specializations Cooperative Banks, Saving Banks, or Real Estate & Mortgage Banks. These banks operate on a smaller geographical scale and so have lower total assets
The relationship between bank performance and the Net Stable Funding Ratio. Evidence from the recent financial crisis
No full textBased on a sample of top-tier international banks, this paper examines the main factors that determine the bank performance and more specifically investigates whether the new structural liquidity measure, the Net Stable Funding Ratio (NSFR), is a key determinant of ROA and ROE. The analysis encompasses two time periods: a pre-crisis period (2003-2006) and a crisis and post-crisis period (2007-2010) and focuses on bank-specific characteristics as well as macroeconomic and industry-specific factors. The results of the empirical analysis indicate that the NSFR becomes significant only during only the crisis and post-crisis period and it is positively related to bank performance. This finding shows that, during the crisis and post-crisis period, banks characterized by values of NSFR below the threshold of 100% are perceived by supervisors as having a less solid capital structure, lower rating and higher overall funding costs. Hence, the impact of the new structural liquidity ratio on bank performance is positive
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Board diversity reforms: Do they matter for EU bank performance?
Full text linkWe examine the impact of governance reforms related to board diversity on the performance of EU banks. Using a difference-in-difference approach, we document that reforms increase bank stock returns up to two years after their introduction. We find that the impact is similar across mandatory and affirmative actions, albeit the former increase bank risk. The performancediversity relationship varies with the type of reform. While gender diversity per se seems to have no significant influence, when women’s presence is mandatory it reduces risk. The effectiveness of reforms depends on a country's institutional environment, its legal origin and its cultural openness to diversity
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
