Is this economy in equilibrium when income equals $245 b? If not, what is the equilibrium level of income for this economy? (solve to two decimal places). Part (7) Illustrate this economy using the aggregate expenditure model. On your diagram, identify the equilibrium level of income as calculated in part 6 and the actual level of income ($245 b). Identify as required the vertical distance that represents unplanned investment calculated in part 4. Ensure you label all axis and each component (line) you draw in your diagram. Part (8) Calculate the tax multiplier for the economy (solve to two decimal places)
