No full text'R&D and export performance: exploring heterogeneity along the export intensity distribution'
No full textThis study analyses the relationship between frm-level innovative efort as measured by R&D expenditures and export intensity. We apply quantile regression techniques to a sample of Italian frms to verify whether R&D expenditures’ efect varies
along the conditional distribution of export intensity, after controlling for censoring
and endogeneity issues. Empirical fndings suggest that the efect of R&D expenditures on export intensity is positive and that frms taking most advantage from
R&D activity are in the right tail of the export intensity distribution (from the 70th
quantile onwards), that is, those exporting 50% of their sales or more. Overall, the
results prove robust to several specifcation checks and suggest not only that frms’
innovative eforts help explaining heterogeneity in export intensity performance, but
also that its positive efect difers across the export to sales ratio distribution. This
implies that innovation policy measures might be more efective for frms characterised by a relatively high export intensive margi
'R&D and export performance: exploring heterogeneity along the export intensity distribution'
Full text linkThis study analyses the relationship between firm-level innovative effort as measured by R&D expenditures and export intensity. We apply quantile regression techniques to a sample of Italian firms to verify whether R&D expenditures’ effect varies along the conditional distribution of export intensity, after controlling for censoring and endogeneity issues. Empirical findings suggest that the effect of R&D expenditures on export intensity is positive and that firms taking most advantage from R&D activity are in the right tail of the export intensity distribution (from the 70th quantile onwards), that is, those exporting 50% of their sales or more. Overall, the results prove robust to several specification checks and suggest not only that firms’ innovative efforts help explaining heterogeneity in export intensity performance, but also that its positive effect differs across the export to sales ratio distribution. This implies that innovation policy measures might be more effective for firms characterised by a relatively high export intensive margin
R&D, innovation and knowledge spillovers: An empirical reappraisal based on cross sectional dependence
No full textBottazzi and Peri (2007) show that the existence of a cointegrating relationship between the domestic
stock of knowledge, domestic R&D and the international knowledge stock can be interpreted as a
support of the semi-endogenous versus the endogenous growth models. We replicate their study in
a wide sense by using three more countries, a more recent time period, a different measure of R&D
resources and by estimating the cointegrating vector with an econometric methodology that is robust
to cross sectional dependence. Our replication confirms Bottazzi and Peri's main results in favour of
the semi-endogenous growth models but finds stronger spillover effect

No full textGoing 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

No full textVariations 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
