Productivity, profitability and financial fragility: Empirical evidence from Italian business firms
Full text linkIn this work we investigate two crucial dimensions of firms' structure and dynamics, that is profitability and productivity performance. The empirical distributions and the associated persistence over time are explored through a set of parametric and non parametric exercises performed on an large panel of Italian firms active in both Manufacturing and Services during the period 1998-2003. The main contribution resides in the use of an index of financial risk which allows us to document that not obvious interactions are in place among economic performances, financial conditions and availability of external credit. We also offer an initial understanding about how profitability and productivity relate with a third dimension of performance, that is firm growth. We find that, independently from the particular sector of activity and from financial conditions, there seems to be little market pressure and little behavioral inclination for the more efficient and more profitable firms to grow faster
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
Assessing the impact of credit ratings and economic performance on firm default
Full text linkThe study of firms' default has attracted wide interest among both practitioners and scholars. However, attention has often been limited to a relatively small set of financial variables. In this work, we try to increase the scope of analysis extending the investigation to other possible determinants of default. In particular, we rely on credit ratings to summarize firms' financial conditions, and we address the potential predictive power of a set of economic dimensions size, growth, profitability and productivity which industrial economics suggest to be meaningful determinants of survival. We present novel results based on a large Italian dataset reporting credit ratings for all the firms in the sample. As far as financial conditions and default are concerned, we find that the firms displaying the worst credit ratings are quite turbulent, but also exhibit non-negligible chances to recover. Moreover, the analysis of the distribution of firms' economic performance reveals that profitability stands up as the only relevant economic variable telling apart defaulting firms from surviving ones, at different time distance to default. Finally, probit and logit estimation of default probabilities, testing for the simultaneous effect of economic and financial dimensions, suggest that growth, in addition to credit ratings, significantly affects the likelihood of default, albeit in a positive (and as such unexpected) way in the manufacturing industry
