Suppose the federal reserve's target for inflation is 2%, the current inflation rate is 2%, and the output gap is 4%. what should be the target for the federal funds rate according to the taylor rule as it is presented in the book?

The target federal funds rate=8%

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%

The interest rate the bank charges you for your loan.

Explanation:

The bank is trying to make money, so the bank is going to PAY you a lower interest rate on your savings account, but CHARGE you a higher interest rate on your loan.  Then, the bank makes more money out of the deal.
