Banks, FinTech and stock returns
No full textThis paper investigates the effect of banks' investment in FinTech firms (FTF) on stock returns. We hand-collect data on 581 investment rounds made by FTFs, within at least one European or North American bank acting as investor. Our results show that banks’ investment in fintech affect stock markets. The abnormal reaction is negative, larger for young and technology-oriented firms, and stronger in the case of multiple investments. Bank size, leverage and profitability do not moderate abnormal returns. Overall, our study suggests that bank equity investment in FTFs is an important determinant of abnormal stock returns
The signaling role of trade credit in bank lending decisions: Evidence from small and medium‐sized enterprises
No full textUsing confidential data at the bank–firm loan-level, we provide direct evidence of the signaling role of trade credit in bank lending decisions. Especially for firms that are opaque in their relationship with banks, the findings reveal that trade credit ameliorates information asymmetries. We address the questions of whether and, if so, how the presence of trade credit affects banks’ decisions to grant commercial loans. We base the analysis on a sample of small and medium-sized enterprises to examine suppliers’ informational advantage in screening activities in relation to relationship lending arguments. We provide evidence that supports the role of trade credit as a signaling instrument in lending decisions. More precisely, the analysis suggests that trade credit plays a signaling role, increasing the probability of obtaining a loan. Suppliers bearing credit risk lead banks to lend to firms. Thus, a bank receiving this signal is more likely to grant a loan even though abnormal payment delays are perceived as negative and function as friction during the lending process. This paper has two implications: Banks should use suppliers to signal a “good” type of borrower and for firms, sharing credit information could ameliorate the rationing problems arising in the context of credit asymmetries. © 2021 John Wiley & Sons Lt
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
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
