Suppose FFRATE is raised to $1\mathrm{.}5\%$ in period $t=5$ and then returned to its original level of $1\%$

for $t=6,7,8,9.$ Use the above equation to forecast INVGWTH for periods $t=5,6,7,8,9.$ Relate

the changes in your forecasts to the values of the coefficients. What are the delay multipliers?
