The collaboration network of Tinbergen Institute

Before TI was established, professors from different universities in the Netherlands rarely cooperated with each other in joint research. In fact, some professors even went so far as to instruct
their students not to cooperate with researchers from other universities - in order to prevent them from getting ‘strange ideas’.1 As a result, when TI was originally established as a graduate school in 1987, it presented an excellent opportunity to lower some of these barriers and provide a means to achieve greater academic collaboration between the participating universities. TI’s 25th anniversary provides us with the perfect occasion to look back and ask: has the TI network indeed resulted
in more collaborative research between different universities?
