As empresas novas, tal como as outras,  não são  todas iguais, não são um bloco homogéneo:

"In this paper, we have shown that there is substantial skewness in the desires and expectations of individuals who start small businesses. Specifically, the vast majority of small business owners do not expect to grow, report not wanting to grow, never expect to innovate along observable dimensions, and report not wanting to innovate along observable dimensions. We also show that there is also substantial heterogeneity in the reported reasons for why individuals start their business.

Our results suggest that much of the current literature has overlooked an important component of many small businesses. Essentially all of the current literature on firm dynamics explains the ex-post distribution of firm size with models emphasizing differences in entrepreneurial talent, differences in entrepreneurial luck, and differential access to credit markets. The results in this paper, however, suggest that another factor may be at play: many small business owners just do not wish to grow big or innovate along observable dimensions in any meaningful way.

Lastly, we conclude that our results suggest that it is often inappropriate for researchers to use the universe of small business (or self employment) data to test standard theories of entrepreneurship. Most small businesses do not match our conceptual measures of entrepreneurship which focuses on  the desire to innovate or grow.  Researchers interested in testing such specific theories of entrepreneurship may need to use more specialized data sets like the ones that track small businesses seeking venture capital funding."

Gosto de recolher tudo o encontro que ajuda a dinamitar a concepção da economia como um bloco homogéneo.
