Poucas pessoas têm interesse em temas tão áridos como a metodologia e epistemologia da economia. Para as que têm, o Mainly Macro tornou-se um ponto obrigatório de paragem. Simon Wren-Lewis escreve praticamente todos os dias acerca dos fundamentos microeconómicos da macroeconomia, da importância desses fundamentos para a modelização via DSGE, do que importa mudar e dos caminhos a seguir. DSGE critics and future directions for macro está longe de ser o melhor post da série; mas é um pretexto tão bom como qualquer outro para recomendar vivamente o melhor blogue do momento sobre teoria pura.
So let me give one argument for reform rather than revolution that I have only made implicitly before. When I studied macro and then began working as a macroeconomist, mainstream macro was divided into schools of thought. In an environment where both inflation and unemployment were high, you had monetarists saying that you just needed to control the money supply, some Keynesians arguing that we should focus on unemployment because it had nothing to do with inflation, and New Classicals saying unemployment was not even a problem. Each school had its models, and each claimed empirical backing. Econometric analysis was not strong enough to discriminate between schools. Different schools tended to talk across each other, and anyone trying to look for common ground or ultimate sources of disagreement had a hard time, and ended up writing lists. For a policymaker or student it must have seemed like a nightmare, and no wonder many chose which school to follow based on its ideological associations.In my view microfoundations brought some order to this chaos (see this from here). Now for heterodox economists who think the microfoundation approach is fundamentally flawed, this is a problem: we are looking at alternatives through the wrong lens. But for those who think that, for at least some problems, basic micro reasoning is a good place to start, microfoundations provided a common language with which to discuss and appreciate different points of view. Note that this is not an argument for complete synthesis, but just a shared language.
