“Eu” ou “Nós”?

Akerlof, há anos, vem numa agenda muito interessante de repensar a modelagem da ação microeconômica incorporando (ou importando) aspectos de outras áreas. Vai emplacar? Não sei. Mas é o Akerlof, né?

Veja a última dele.

Increasingly, economists are drawing on concepts from outside economics–such as “norms,” “esteem,” and “identity”–to model agents’ social natures. A key reason for studying such social motivation is to shed light on the conditions that facilitate–or deter–collective action. It has been widely observed, for instance, that groups are more able to engage in collective action when they have a common, group identity. This paper gives one explanation for such a link. The paper develops a new concept, “we thinking”; and it also provides a deeper understanding of the concepts of norms, identity, and esteem.

Legal, né?


A Curva de Phillips vai bem, obrigado

Blanchard em artigo curto e interessante, aqui.

Eis o resumo:

This paper reexamines the behavior of inflation and unemployment and reaches four conclusions: 1) The U.S. Phillips curve is alive and well (at least as well as in the past). 2) Inflation expectations however have become steadily more anchored. 3) The slope of the curve has substantially declined. But the decline dates back to the 1980s rather than to the crisis. 4) The standard error of the residual in the relation is large, especially in comparison to the low level of inflation. Each of the four conclusions presents challenges for the conduct of monetary policy.
