La dinamica del debito pubblico in Italia: un’analisi empirica (1958-2013)
No full textIn this paper time series analyses are shown in order to study the relationships between
government debt/GDP and its macroeconomic determinants (such as primary balance/GDP,
real GDP, the inflation rate and the average interest rate on Treasury bills) in the period
1958-2013 in Italy. Consistent with the theory, the results reveal a significant causal
relationship moving from the primary balance to the real growth rate, as well as a clear
influence of the inflation on the interest rate. In contrast, the influence of public debt on
growth rate emerges only marginally. Further tests have, however, highlighted a significant
influence of public debt on the extent of primary balance, but also a non-negligible effect of
growth rate on both public finance’s indicators. These empirical evidences can be
considered particularly useful for the policies that Italy face in the new European
governance, suggesting to proceed with caution in the budgetary consolidation program and
giving greater emphasis on growth policies
Job polarization in Italy: structural change and routinization
Get PDFThis paper analyzes the role of structural change and the routinization hypothesis as
concurrent explanations for job polarization in Italy over a fifteen-year period: 2004-2019.
We observe that, even though the structural change pattern of Italian employment is
characterized by the pronounced contraction of the most routine-intensive sector of the
economy – i.e. the manufacturing sector – the disappearance of routine employment is a
more generalized phenomenon that is affecting transversally all sectors. Indeed, by
means of a standard shift-share decomposition method, the contraction of routine
employment in Italy turns out to be marginally driven by the structural change pattern
and the decline of the manufacturing sector – with only a negligible 20 percent of the
total contraction attributable to the between-industry dimension. We find instead robust
evidence in favor of the technological argument. The routinization hypothesis is tested
with OLS and 2SLS models by exploiting industry-province cell variations and results point
out that routine-tasks specialization does significantly increase employment in low-skill
occupations for 6 out of 8 broad industries covering around 90 percent of non-farm
private employment
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Employment effects of temperature shocks in Italy and the role of occupational heat stress
Get PDFWe assess the employment impact of temperature shocks in Italy by taking into consideration the role of occupational heat stress. Combining labor-market survey data with ground-station gridded weather information, we run non-linear panel fixed-effects regression models over 2011-2019 and estimate around half percentage-point contraction in provinces’ employment rates for a two Celsius degrees shock in average quarterly temperatures. This effect doubles in magnitude for provinces in coastal and southern climatic zones. By exploiting narrowly-defined 4-digit occupation survey information, we show that our results are significantly driven by individuals previously-employed in occupations relatively more exposed to extreme temperatures. This subset of non-employed significantly accrues to the private service sector and is equally split between unemployment and inactivity.we assess the employment impact of temperature shocks in italy by taking into consideration the role of occupational heat stress. combining labor-market survey data with ground-station gridded weather information, we run non-linear panel fixed-effects regression models over 2011-2019 and estimate around half percentage-point contraction in provinces’ employment rates for a two celsius degrees shock in average quarterly temperatures. this effect doubles in magnitude for provinces in coastal and southern climatic zones. by exploiting narrowly-defined 4-digit occupation survey information, we show that our results are significantly driven by individuals previously-employed in occupations relatively more exposed to extreme temperatures. this subset of non-employed significantly accrues to the private service sector and is equally split between unemployment and inactivity. employment effects of temperature shocks in italy and the role of occupational heat stress marco biagetti valerio intralig

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
