The document analyzes motivations for entrepreneurship using survey data from 1,000 entrepreneurs and interviews with 40 entrepreneurs. It finds that while necessity entrepreneurship is common, motivations are complex, with autonomy, challenge, financial goals, and family legacy also playing important roles. Entrepreneurial motivations are generally stable but increased in importance during the recession, with recession-era entrepreneurs more ambitious. Higher growth expectations, linked to challenge and financial motivations, influence business performance and survival rates more than opportunity-necessity distinctions alone.
