"Social impact accelerators (SIAs) seek to select startups with the potential to generate financial returns and social impact. Through the lenses of signaling theory and gender role congruity theory, we examine 2324 social startups that applied to 123 SIAs globally in 2016 and 2017 and find that SIAs are more likely to accept startups that signal their economic and social credibility. Moreover, while we find that the influence of these signals is strongest when they are congruent with the stereotypes associated with the lead founder's gender, men seem to experience better outcomes from gender incongruity than women."

"Despite the emergence of startup accelerators as venture development organizations (VDOs) to high-growth firms, research has yet to identify where these accelerators fit into the venture development ecosystem. By clarifying and reviewing three different subsystems in the entrepreneurial ecosystem, our paper proposes that as an extension of the current incubation mechanism, accelerators contribute to the entrepreneurial ecosystem by transforming entrepreneurs and their ventures at early stages. Drawing upon the Pipeline model (Lichtenstein, G. A., and T. S. Lyons. 2006."Managing the community's pipeline of entrepreneurs and enterprises: A new way of thinking about business assets." Economic Development Quarterly 20 (4): 377-386.), we first plot where the accelerator model fits in the broader entrepreneurship ecosystem, and then demonstrate how different types of accelerators help participating entrepreneurs and their ventures progress along the venture development pipeline. Our theoretical approach contributes to both the entrepreneurship ecosystem and the accelerator literature and provides a practical map for both policymakers and early-stage entrepreneurs to manage and utilize their entrepreneurship ecosystem more effectively."
