Entrepreneurial self-efficacy (ESE) – the belief in one’s ability to successfully engage in entrepreneurial behavior such as starting a business - is an important antecedent of entrepreneurial intention and start-up behavior. Individuals with high self-efficacy are more likely to start businesses than those with low self-efficacy. Subjective norms – what individuals think other people think about their behavior - are also associated with influencing behavior. In this research, we examine longitudinally how subjective norms influence ESE, entrepreneurial intentions, and start-up behavior.
