Assume a closed economy with no government. Suppose that autonomous consumption equals $400, planned investment equals $500, and the mpc equals 0.9.
1. Using the information in Situation 20-1, if aggregate output is equal to $10,000, then unplanned inventory investment equals
2. Using the information in Situation 20-1, the equilibrium level of aggregate output is
3. Using the information contained in Situation 20-1, if autonomous consumption increases by $100, then equilibrium aggregate output will change by
4. Using the information contained in Situation 20-1, if planned investment decreases by $100, the equilibrium aggregate output will change by
