1. Calculate AE given the information below and completely fill in the table.
2. Where is equilibrium in this economy based on the table?
3. Using the injections-withdrawals approach complete the table and demonstrate that the point you chose in part 2 is the equilibrium.Go back to Chapter 8 if you forget how this is calculated.
4. Create another table and recalculate AE assuming that consumption has decreased at all levels by $25 (e.g. instead of consumption of 125 when total income is 95, consumption becomes 100).
5. Where is equilibrium in this economy now? (highlight the row)
6. Using the injections-withdrawals approach, complete the table again and demonstrate that the point you chose in question 4 is the equilibrium now.
7. If this economy had exports, explain the impact of the net export effect on fiscal policy, providing an example.
Taxes: $10 at each level of income
Investments: $15
Government Spending: $25
