Returns to Open Source Software Engagement: An Empirical Test of the Signaling Hypothesis
Juergen Bitzer, Ingo Geishecker, Philipp J.H. Schroeder · RePEc: Research Papers in Economics · 2010
Job-Market signaling is ranked high among the explanations why in- dividuals engage voluntarily in OSS projects. If true, signaling implies the existence of a wage premium for OSS engagement. However, due to a lack of data this issue has not been tested previously. Based on a novel data set comprising detailed demographic and wage information for some 7,000 German IT employees, this paper fills this gap. In the empirical analysis, however, we find no support for the signaling hypothesis, a result that is robust to different measures of OSS involvement and different model specifications.
