SETTLE down at one of São Paulo's sushi bars and before long you will overhear a discussion about a start-up business making energy from obscure weeds, or some other bright idea for relieving members of the country's growing middle class of their disposable income. A field study of this kind displays a strong sample bias, but the point is clear: Brazil does not lack go-getters. Yet according to a more thorough survey backed by the International Finance Corporation (IFC), a sister organisation of the World Bank, Brazilian entrepreneurs are a strikingly different breed to their peers in Russia and China.

Overall, some 82% of entrepreneurs in all three countries came from families with at least one other entrepreneur. They also tended to be taller than the average. But there the similarities end. In particular, Brazilian entrepreneurs seem to have a much lower appetite for risk.
