Qual o valor do auto-interesse?

The article critically reviews past and current justifications for the theoretical use of the behavioral assumption of self-interest, explanatory, normative, representational and critical, focusing on the critical function. This latter emerges from an incursion into the modern history of ideas and may be shown still to fertilize a number of contemporary economic approaches.

As razões do laissez-faire: uma análise do ataque ao mercantilismo e da defesa da liberdade econômica na Riqueza das Nações

The reasons of the laissez-faire: an analysis of the attack to mercantilism and of the defense of economic liberty in The Wealth of Nations. The main reasons presented in The Wealth of Nations to advocate the system of economic liberty and reject mercantilism are analyzed. These two systems are evaluated considering basically their impact on the annual product, and the degree of liberty and justice they engender. Based on his views of man and of capital hierarchy, Smith defends the superiority of economic liberty in what concerns the growth of the annual product. This system is also considered superior to mercantilism in terms of justice since it does not privilege any sector of society and allows a great level of liberty to the individuals.

Ciência econômica e modelos de explicação científica: retomando a questão

Economic science and scientific explanation models. Economics was born under the sign of methodological vagueness. The first author who tried to solve the question (John Stuart Mill) asserted that it is a kind of knowledge that uses the abstract (direct deductive) method but also that it is an exception because for all other phenomena in the field of moral science the correct method is the inverse deductive or historical method. On the other side, functionalist explanations that are condemned by the scientific precepts of economics are present in the science since its beginning with Adam Smith. Economics went ahead without worriment about these methodological issues but this indefiniteness has never gone off stage. Since the start of XXI century new facts are emerging. Developments in Psychology are giving a new breath to Friedman's point of view and seem to fortify the mainstream (Rogebert e Nordberg, 2005), whereas unfolding in complexity science promises to throw it down and put in its place another kind of explanation borrowed from Biology (Beinhocker, 2006). All this stimulates to retake the question. We do this here, under a critical vision, taking the taxonomy of scientific explanations framed by modern positivism.
