Fig. 3 shows the reaction of theCPI inflation to shocks on the other variables. It is notorious
that inflation is affected by the interest rate as expected. On the other hand, it declines as a
result of a shock to the exchange rate,which seems to be counterintuitive at a first glance.This
may be explained, however, by the effectiveness of the interest rate. Shocks to the exchange
rate set off sudden reaction on the interest rate, which reduces the CPI inflation by
overcoming the eventual effect of the exchange rate devaluation on the price level.
