Teoria dos Jogos e Política Monetária

Uma aula em poucas palavras por Mankiw:

"Suppose the Fed has a long-term inflation target. And suppose the Fed followed this rule:


Look at the market's forecast of interest rates and inflation over the next few years. If the market expects inflation above target, set a path for interest rates a bit higher than the market expects. If the market expects inflation below target, set a path for interest rates a bit lower than the market expects. If the market expects inflation to come in on target, set a path for interest rates equal to what the market expects.

This might seem circular: The Fed is responding to the market, and the market is responding to the Fed. But there is nothing wrong with that. Economists are used to simultaneity."


Poucas palavras, e uma citação breve do que seria um ponto fixo, e está estabelecida uma regra razoável de política monetária.

Abraços!
