Conferência organizada pelo FMI sobre o que precisa mudar nos princípios de condução de política macroeconômica. Segundo Blanchard:
Before the global economic crisis, mainstream macroeconomists had largely converged on a framework for the conduct of macroeconomic policy. The framework was elegant, and conceptually simple. Caricaturing just a bit, it went like this:
•The essential goal of monetary policy was low and stable inflation. The best way to achieve it was to follow an interest rate rule. If designed right, the rule was not only credible, but delivered stable inflation and ensured that output was as close as it could be to its potential.
•This was achieved by setting the key policy rate that then affected the term structure of interest rates and asset prices, and then to aggregate demand. One could safely ignore most of the details of financial intermediation. Financial regulation was outside the macroeconomic policy framework.
•On currencies, countries could set an inflation target and float, or instead choose a hard currency peg or join common currency areas. In general, in a world in which central banks followed inflation targeting, there was no particular reason to worry about the level of the exchange rate or the current account balance. Certainly, attempting to control exchange rates through capital controls was undesirable. And multilateral coordination was not required.
•Fiscal policy had a limited role at best, at least in the short run. With the right use of monetary policy, it was not really needed. Automatic stabilizers, such as unemployment benefits, would kick in during downturns, but discretionary policy was more likely to be misused than used well. The focus had to be on the medium run, and on fiscal sustainability.
These were simple principles, and they seemed to work. From the early 1980s on, macroeconomic fluctuations were increasingly muted, and the period became known as the “Great Moderation”. Then the crisis came. If nothing else, it forces us to do a wholesale reexamination of those principles.
Engracado, nenhuma palavra entre o relacionamento do FED com o setor privado... esse sim uma fonte importante de confusao.
