ABSTRACT. Gavin affirms that the official adoption of an inflation target communicates information about policymaker’s inflation objective, and the interest rate rule transmits all money demand shocks into the money supply. Sousa and Zaghini assume the global liquidity aggregate to react in the same quarter to shocks on real income, the price index and the short-term interest rate. Amin observes that the new social democratic narrative assumes that a new global regulatory regime will be able to tackle the abuses of an unregulated capitalism without the need to alter its fundamentals.
