  This work provides an in-depth analysis of the relation between the different
types of collaboration and research productivity, showing how both are
influenced by some personal and organizational variables. By applying different
cross-lagged panel models, we are able to analyze the relationship among
research productivity, collaboration and their determinants. In particular, we
show that only collaboration at intramural and domestic level has a positive
effect on research productivity. Differently, all the forms of collaboration
are positively affected by research productivity. The results can favor the
reexamination of the theories related to these issues, and inform policies that
would be more suited to their management.
