Small business activity does not measure entrepreneurship

Abstract

Entrepreneurship policy mainly aims to promote innovative Schumpeterian entrepreneurship. However, the rate of entrepreneurship is commonly proxied using quantity-based metrics, such as small business activity, the self-employment rate, or the number of startups. We argue that those metrics give rise to misleading inferences regarding high-impact Schumpeterian entrepreneurship. To unambiguously identify high-impact entrepreneurs we focus on self-made billionaires (in US dollars) who appear on Forbes Magazine's list and who became wealthy by founding new firms. We identify 996 such billionaire entrepreneurs in 50 countries in 1996-2010, a systematic cross-country study of billionaire entrepreneurs. The rate of billionaire entrepreneurs correlates negatively with self-employment, small business ownership, and firm startup rates. Countries with higher income, higher trust, lower taxes, more venture capital investment, and lower regulatory burdens have higher billionaire entrepreneurship rates but less self-employment. Despite its limitations, the number of billionaire entrepreneurs appears to be a plausible cross-country measure of Schumpeterian entrepreneurship.

Varieties of entrepreneurship: exploring the institutional foundations of different entrepreneurship types through ‘Varieties-of-Capitalism’ arguments

“…Keuschnigg and Nielsen 2004). Additionally, effective tax treatments of options contracts were needed to enable VC firms to appropriately incentivize founders to foster innovative firms (Henrekson and Rosenberg 2001;Henrekson and Sanadaji 2014). Taken together, we expect that institutions facilitating the availability of venture capital stimulate the development of Schumpeterian entrepreneurial ventures.…”

Measuring entrepreneurship: Type, motivation, and growth

“…New firm formation-interchangeably also called "new venture creation," "entry," and "new business"-is frequently considered an appropriate measure for entrepreneurship [8]. New firm formation represents the creation of a new organizational entity, which is born in order to pursue a market opportunity.…”

Local Competitiveness Fostered through Local Institutions for Entrepreneurship

“…Instead of focusing on quantitative aspects of entrepreneurship, entrepreneurship policy should focus more on the qualitative aspects. Empirical evidence suggests that an economy that fosters (a few) high-impact entrepreneurial firms and highgrowth firms is superior to an economy that tries to maximize the number of SMEs or the rate of selfemployment (Shane 2008;Henrekson and Sanandaji 2014). Figure 1 depicts the major distinctions between SME policy and entrepreneurship policy.…”
