To address this fundamental question, we introduce founder social identity and economic prosperity as potential explanatory factors that are still insufficiently understood. Specifically, we theorize that having a Darwinian, Communitarian, or Missionary founder social identity affects the transition from nascent to active entrepreneurship in distinct ways. Furthermore, we expect economic prosperity to act as a relevant contingency factor. We test our hypotheses in a two-wave dataset of nascent entrepreneurs from the GUESSS project and conduct a supportive post-hoc analysis in a sample of nascent entrepreneurs from a longitudinal PSED-type study (SwissPEB). We find support for most of our expectations, namely that having a Communitarian or Missionary founder social identity makes the nascent-active transition more likely and that economic prosperity moderates the Darwinian- and Communitarian-related main effects.journal-article
