Excelente paper produzido por Edward Glaser e Rafael La Porta, ambos da Harvard University sobre os aspectos institucionais do crescimento econômico.
We revisit the debate over whether political institutions cause economic growth, or whether,
alternatively, growth and human capital accumulation lead to institutional improvement. We find
that most indicators of institutional quality used to establish the proposition that institutions cause
growth are constructed to be conceptually unsuitable for that purpose. We also find that some of the
instrumental variable techniques used in the literature are flawed. Basic OLS results, as well as a
variety of additional evidence, suggest that a) human capital is a more basic source of growth than
are the institutions, b) poor countries get out of poverty through good policies, often pursued by
dictators, and c) subsequently improve their political institutions.
