| 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 using a novem database of French academics. The main empirical result is that the number and the quality of a researcher's co-authors reflect the productivity of this researcher. |

| 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. |

| Abstract: | This paper focuses on the properties of the matching process which leads to scientific collaboration. In a first step, it proposes a simple theoretical model to describe the intertemporal choice of researchers facing successive opportunities of co-authoring papers. In a second part, the paper empirically assesses the properties of the model. The main empirical result is that the number and the productivity of a researcher's co-authors reflect the productivity of this researcher. This result is consistent with the assumption that co-authorship is motivated by a willingness to increase both the quality and the quantity of research output. As researchers with a lot of influent publications papers may create links with a large number of influential co-authors, co-authoring with highly productive academics appears as a signaling device of researchers' quality. |

| Abstract: | This paper analyzes the production of fundamental research as a coordination game played by scholars. In the model, scholars decide to adopt a new idea only if they believe that a critical mass of peers is following a similar research strategy. If researchers observe only a noisy idiosyncratic signal of the true scientifi c potential of a new idea, we show that the game presents a single threshold equilibrium. In this environment, fundamental research proceeds with large structural breaks followed by long periods of time in which new ideas are unsuccessful. The likelihood of a new idea emerging depends on various parameters, including the rewards of working in the old paradigm, the critical mass of researchers required to create a new school of thought and scholars ability to properly assess the scientifi c value of new ideas. |
