This is a notable effort (by Paulo Guimaraes and Miguel Portela) in compiling and disseminating information about the work done by Portuguese economists (and non-Portuguese economists based in Portugal) in pushing the frontiers of knowledge in the "dismal science".
According to the website, there's somewhat surprising evidence that 2010 was a not very good year in terms of academic results, given the upward trend starting in the mid-1980s. But perhaps this is only a one-off blip (or, alternatively, 2008 and 2009 were one-off spikes):
Here's the list of top 10 economists, according to one of the many criteria (summing all research contributions since 1970 and weighting each article using a combination of metrics):
1: Sergio Rebelo, Northwestern U
2: Luis Cabral, New York U
3: Pedro Pita Barros, U Nova
4: Miguel Villas-Boas, U CA, Berkeley
5: Nuno Garoupa, U Illinois
6: Alfredo Marvão Pereira, Col William & Mary
7: João Santos Silva, U Essex
8: Guilherme Carmona, U Nova
9: Nuno Limão, U Maryland
10: Pedro Portugal, U Nova
It's interesting to note that only three out of those ten economists are based in Portugal (and all of those are in the same university, Nova).
