“Nothing is so practical as a good theory” Kurt Lewin (1945). This statement still applies. According to Van de Ven (1989), a good theory is practical because it advances the knowledge in a scientific discipline, guides research toward crucial questions and informs practice. Analyse and discuss the challenges of building a good theory of entrepreneurship. Your essay should be informed by theoretical perspectives that seek to explain the actions and logic that underlie entrepreneurial behaviour, as found in high quality academic literature.
