Problem 4. Consider a closed economy without government. Since the economy is closed, X=0 and IM =0. Because there is no government in this economy, G=0,T=0 and TR=0. In such an economy, we have GDP=C+1YD=GDP The following table shows the data on GDP, disposable income (YD), consumption (C), planned investment (IPlanned), where it is assumed that IPlanned=$500 You want to find the equilibrium level of GDP in this economy. 1. Recall that aggregate planned spending (AE Eplanned) is defined as AEPlanned=C+IPlanned Using this definition, complete the column for AE Planned. 3. Complete the column for lunplanned. 4. What is the level of I Inplanned when the economy is in equilibrium? 5 . Is the value of IUnplanned positive or negative if GDP AE Planned
