Bank foundations, social capital and the growth of Italian provinces
No full textThe funding role of bank foundations in the Italian economy, especially to the non-profit sector, significantly increased over the last 25 years. This paper constructs a novel measure of social capital at the provincial level that explicitly takes into account the bank foundations’ sectors of intervention (such as education, public health, and art and culture), together with other traditional aspects of social capital, and then tests the impact of bank foundations on the economic growth of Italian provinces. The findings suggest that the contribution of bank foundations to social capital positively affects the economic growth of provinces
Imprese innovative e accesso al credito. Un’indagine empirica
No full textQuesto lavoro mira ad analizzare l’accesso al credito delle imprese innovative testando
l’impatto della natura innovativa delle imprese: (a) sul costo del credito bancario; (b) sulla
probabilità di restrizione del credito. L’analisi empirica utilizza le informazioni ottenute
dall’unificazione di due database distinti e di diversa derivazione. Il primo database contiene
informazioni di natura finanziaria su oltre 15.000 linee di credito concesse da un’istituzione
bancaria ad imprese di diversa tipologia dimensionale e giuridica operanti in 23 settori industriali.
Il secondo database identifica le imprese che svolgono attività innovativa. Le stime
econometriche mostrano che le imprese innovative hanno una minor probabilità di restrizione
del credito rispetto a quelle tradizionali. L’innovazione si potrebbe dunque configurare
una via per il superamento del credit crunch.This paper aims at analyzing the access to credit of innovative firms by means of two empirical
models that estimate the impact of innovative nature of firms on: (a) the loan interest
rate; (b) the probability of overdraw. We use information gained by two dataset. The first
one contains data on more than 15,000 lines of credit of a bank to firms that operate in 23
different industrial sectors. The second dataset indentifies the firms that can be defined innovative
according to a narrow set of activities carried out. The findings show that innovative
firms have a lower probability of being credit rationed than supplier dominated firms
Estimating the relationship between collateral and interest rate: A comparison of methods
Full text linkThis paper uses a variety of estimation methods to explore the empirical relationship between interest rate and collateral requirements in bank loan contracts. Methods that do not allow for endogenous contract terms detect a positive reciprocal association between interest rate and collateral. Methods that allow for endogenous contract terms point to a strong positive effect of interest rate on collateral but the effect of collateral on interest rate is weaker. This highlights the importance of incorporating the endogenous nature of contract terms in empirical work
The role of universities in the location of innovative start-ups
No full textStart-ups increasingly find the prospect of university–industry collaborations to be a powerful driver of innovation and entrepreneurship activity. Moreover, at the geographical level, they are attracted by teaching and research institutions, either public or private. This paper focuses on the role played by universities. Our hypothesis is that geographical proximity favors the transfer of knowledge and technology from universities to industries and, consequently, represents a positive factor for regional economic development. Results show that university spillovers are positively correlated with the creation of innovative start-ups. Furthermore, the presence of human capital (graduates) exerts a significant influence on the location decisions of start-ups, being a source for competitiveness for firms close to universities. Research quality, especially in the social sciences area, attracts innovative start-ups, while third-mission activities have a weak impact on locational choice
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
