In a new paper published today in PNAS, Jacopo and I try to extract as much information as possible from an ostensibly meager source of data: a list of the names of all the researchers working in Italy, at the Centre National de la Recherche Scientifique in France, and at public universities in the US.
We show that by using simple randomizations, one can highlight several interesting facts about these different academic systems.
The work is a bona fide exercise in style: by introducing subtle variations of the randomization algorithm, we show that in Italy researchers work in the region where they were born and raised, while in the US geography does not influence the distribution of researchers; in France, we can detect academic couples working in the same unit; we demonstrate that academic nepotism in Italy (the focus of a previous paper of mine) is declining; finally, we show that in the US immigration is field-specific.
