  In the past 15 years, two international observatories have been intensively
studying entrepreneurship using empirical studies with different methodologies:
GEM and PSED. Both projects have generated a considerable volume of scientific
production, and their intellectual structures are worth analyzing. The current
work is an exploratory study of the knowledge base of the articles generated by
each of these two observatories and published in prestigious journals. The
value added of this work lies in its novel characterization of the intellectual
structure of entrepreneurship according to the academic production of these two
initiatives. The results may be of interest to the managers and members of
these observatories, as well as to academics, researchers, sponsors and
policymakers interested in entrepreneurship.
