	abstract = {This paper contributes to the open source software (OSS) literature by investigating the likelihood that a participant becomes a project leader. Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity. Harvard Business Review September-October. pp. 84-93; Mateos-Garcia, J., Steinmueller, W.E., 2003. The Open Source Way of Working: A New Paradigm for the Division of Labour in Software Development?

	abstract = {This paper studies the emergence of entrepreneurs and their skill profile in the open source software community. We test the hypothesis that entrepreneurs, carrying out complex, multi-task activities, have more balanced skill sets compared with individuals who are less involved in project management activities. Our empirical analysis employs the SourceForge dataset containing information on 77,039 individuals working in 54,229 OSS projects. We estimate logit and ordered logit models to explore the likelihood that an individual is a project founder or manager. Our main regressors include individual attributes like skill level and diversity, and project-level controls. Results support our hypothesis.},

	year = {2006},

	abstract = {This paper investigates the role of skills and the division of labor among participants in collective inventions. Our analysis draws on a large sample of projects registered at Sourceforge.net, the world{\textquoteright}s largest incubator of open source software activity. We test the hypothesis that the level of skills of participants and their skill variety are important for project performance. Skill heterogeneity across participants is in line with two fundamental organizational features of the open source development model: team work and modular design. We also explore the hypothesis whether the level of modularization of project activities is an important predictor of performance. Our econometric estimations show that both skill level and skill heterogeneity positively affect projects{\textquoteright} survival and performances. However, the impact of skill diversity is non linear. Design modularity is also positively associated with the performance of the project.},
