Suppose that an economy is in the Long-run and Short-rim equilibrium before 2003. In 2003, the households of the economy suddenly change their consumption-saving behavior. Given their disposable income, they save more and consume less. However, the change in the behavior occurs only in EMS. After 2M3, their saving-constunption behavior goes back to normal. In the model with IRAS-ERAS-AD, address the following two questions. (a) Will the change in the behavior of the household in 2003 affect the real GDP and potential real GDP of the economy in EDIE? If yes, explain why they will change and how (increase or decrease). If no, explain why they will not change. {b} Will the change in the behavior of the household in 2003 affect the real GDP and potential real GDP of the economy after 2003? If yes, explain why they will be change and how (increase or decrease]. If no, explain why they will not change
