This Research Handbook argues that the study of entrepreneurs as leaders is a gap in both the leadership and the entrepreneurship literatures. With conceptual and empirical chapters from a wide range of cultures and entrepreneurship and leadership ecosystems, the Research Handbook for the first time produces a systematic overview of the entrepreneurial leadership field, providing a state of the art perspective and highlighting unanswered questions and opportunities for further research. It consolidates existing theory development, stimulates new conceptual thinking and includes path-breaking empirical explorations.
