| Abstract: |
Increased specialization and extensive collaboration are common behaviours in
the scientific community, as well as the evaluation of scientific research
based on bibliometric indicators. This paper aims to analyse the effect of
collaboration (co-authorship) on the scientific output of Italian economists.
We use Social Network Analysis to investigate the structure of co-authorship,
and econometric methodologies to explain the productivity of individual
Italian economists, in terms of "attributional" variables (such as age,
gender, academic position, tenure, scientific sub-discipline, geographical
location, etc.), "relational" variables (such as propensity to cooperate and
the stability of cooperation patterns) and "positional" variables (such as
betweenness and closeness centrality indexes and clustering coefficients). |
