ESE refers to the strength of a person’s belief that he or she is capable of successfully performing the various roles and tasks of entrepreneurship. It consists of five factors: marketing, innovation, management, risk-taking, and financial control. We conducted two studies, one on students and the other on small business executives. Study 1 found that the total ESE score differentiated entrepreneurship students from students of both management and organizational psychology, and that across the three types of students, ESE was positively related to the intention to set up one’s own business. We also found the entrepreneurship students to have higher self efficacy in marketing, management, and financial control than the management and psychology students. In study 2, we simultaneously tested effects of ESE and locus of control on the criteria of founders vs. nonfounders of current businesses. After controlling for individual and company background variables, the effect of ESE scores was significant, but the effect of locus of control was not. More specifically, it was found that business founders had higher self-efficacy in innovation and risk-taking than did nonfounders.
