Em sua Nobel Lecture, Stiglitz se pergunta como as graves deficiências do paradigma neoclássico não o varreram das mentes dos seus mais ardorosos defensores, os economistas ortodoxos: “But one cannot ignore the possibility that the survival of the paradigm was partly because the belief in that paradigm, and the policy prescriptions, has served certain interests”. Palavras de Prêmio Nobel de Economia.

Os mercados não são perfeitos e existem desequilíbrios entre oferta e demanda que extrapolam o simplório arcabouço teórico dos ortodoxos. Information Economics é o nome do novo paradigma proposto por Stiglitz: “Problems of information are central to understanding not only market economics but also political economy”.

Para o Brasil, merece reflexão o seguinte comentário de Stiglitz: “I have criticized the Washington consensus development strategies partly on the grounds that they perceived of development as nothing more than increasing the stock of capital and reducing economic distortions. But development represents a far more fundamental transformation of society, including a change in ‘preferences’ and attitudes, an acceptance of change and an abandonment of many traditional ways of thinking”.

Enfim, o alargamento das perspectives analíticas se faz necessário.
