Some new results on interest rate rules in EMU and in the US

This paper offers two new results on interest rate rules. First, we show that the empirical evidence from 1970 onwards for the US is compatible with a Taylor rule when we consider the possibility of changes in the inflation target and in the real interest rate. Second, recursive estimates of a forward-looking version of the Taylor rule for EMU confirm an increasing weight for inflation in the area, possibly as a consequence of the EMS, and, furthermore, a convergence in the nineties to the German value observed for the whole period. This process has coincided with an important reduction in the deviation of inflation across EMU countries.
