Abstract : This paper aims at estimating the determinants of co-authorship in economics. More specifically, we test the existence of a potential relationship between the research efficiency of an individual and that of his co-authors (the so called assortative matching hypothesis) using a novel database of French academic scholars. However, individual research productivity should be an endogenous regressor as the quality of an academic-s publication will depend somehow on the quality of his co-authors. We have applied the Two Stage Residual Inclusion (2SRI) approach in order to take into account this endogeneity bias. The main empirical result is that the number and the quality of a researcher-s co-authors reflect the productivity of that researcher.There is also a significant gender effect: being a woman has no impact on the probability of never collaborating with other economists but it decreases both the quality and the quantity of co-authors. Finally, lifetime cycles are also an important determinant of the co-authorship trend as the social imprinting hypothesis would suggest. So institutional changes occurred in French academia in mid-eighties have had a large impact on individual research productivity.
