Rischio sistemico e assetti proprietari delle banche europee
No full textLa recente pandemia, la crisi finanziaria e del debito sovrano hanno dimostrato quanto
sia importante monitorare il rischio sistemico. Infatti, banche efficienti favoriscono la
crescita e l’economia reale. In questo contesto, la minimizzazione dei costi di agenzia
è una condizione necessaria per lo sviluppo e la stabilità del sistema bancario, in modo
da garantire una più corretta allocazione delle risorse finanziarie. Utilizzando un campione
europeo sulla struttura proprietaria delle banche, il seguente articolo si pone un
duplice obiettivo: studiare la relazione tra il rischio sistemico e l’assetto azionario della
banca e identificare il canale attraverso cui tale relazione si manifesta. Coerentemente
con la teoria dei costi di agenzia, i risultati ottenuti suggeriscono che una struttura azionaria
più concentrata si associa a un minor livello di rischio sistemico, mentre il rischio
di credito rappresenta il principale canale attraverso cui la struttura proprietaria influenza

A comparison between capitalization-weighted and equally weighted indexes in the European equity market
No full textThis article aims at comparing two major equity index construction methodo- logies, the capitalization-weighted and the equally weighted approaches. Focusing on the constituents of the DJ Euro Stoxx index from January 2002 to December 2011, it provides further evidence to add to the established literature on this topic, of the higher risk-adjusted returns achieved by equally weighted portfolios in comparison with cap-weighted indexes. The novelty of our study is that we test these findings on the Euro stock market by using four reweighting frequencies (monthly, quarterly, semiannually and annually) with the aim of identifying that which is most able to maximize the benefits of the contrarian strategy implicit in the equally weighted approach. Moreover, it is demonstrated that the excess returns are not driven solely by a ‘size effect’ that usually explains the difference in perfor- mance of the two methodologies. Finally, we confirm our results by performing a Fama- French (1992) three-factor regression analysis and also by using a portfolio approach based on the market capitalization of the index constituents. To evaluate the implementation of the EW strategy, from an operational perspective, we estimate the related transaction costs and show that trading costs are not able to affect the main results
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
Is relationship lending still a mixed blessing? A review of advantages and disadvantages for lenders and borrowers
No full textRelationship lending is a common lending technology that is assumed to bring several benefits to small-medium enterprises (SMEs) and to financial institutions that adopt it. Notably, it could reduce information asymmetries, permitting banks to offer better credit terms to the borrower. However, it also entails some costs for both sides. The empirical evidence so far has not been conclusive in determining under what conditions relationship lending can be beneficial or harmful. Most of the studies suggest that SMEs that engage in relationship lending benefit from more credit availability (especially during a financial crisis), and lower interest rates. This occurs when they are served by small banks, are geographically close to the lender, when the bank is adequately decentralized and when it is the dominant creditor of the firm. However, under certain circumstances, banks can extract rents from the borrower or be captured by him. In addition, the consequences and the future of relationship lending will be remarkably affected by the level of competition among banks, their ownership structure, the regulatory framework and the business model that banks will have to adopt accordingly
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
