Question
Suppose that the central bank has the policy "set R equal to 3 if inflation equals 2% and
GAP = 0. Raise R by 0.5 points for every point of inflation above 2%. Reduce R by 0.5
points for every point that inflation falls shortof 2%. Increase R by 1 point for every
percentage point of GAP, if GAP > 0. Reduce R by 1 point for every percentage point of
GAP, if GAP < 0."
All but one of the following is an equation that is consistent with this rule. Which is the
exception?
OR-3+0.5( - 2) + GAP
OF-2+1.5n + GAP
OF- 3+0.5(n - 2) + GAP + n
R-2+n+ GAP
