Answer:
The target federal funds rate=8%
Step-by-step explanation:
The formula for calculating the target federal funds rate is as follows;
I=R*+PI+0.5(PI-PI*)+0.5(PO-PO*)
where;
I=Target federal funds rate
R=real interest rate
PI=inflation rate
PI*=target inflation rate
PI-PI*=Inflation gap
PO=current output
PO*=target output
PO-PO*=output gap
This can be written as;
Target federal funds rate=real interest rate+inflation rate+0.5×(inflation gap)+0.5×(output gap)
where;
R=2%
PI=2%
PI*=2%
PI-PI*=2-2=0%
PO-PO*=4%
replacing;
Target federal funds rate=2+2+0+4%=8%
The target federal funds rate=8%
