BRAVO !!!

Following Geoff’s comment on intellectual externalities, now they are spreading to the University of Arizona where my next semester will be devoted to teach the tools learned in Luc’s class in 2002. May be we should explore this new type of connection further and name it “the intellectual weight matrix”.
Many thanks for your contribution. It’s a pleasure to see spatial statistics and spatial econometrics being applied to many different topics of regional science. I look forward to see you again in Toronto.
