- Which equation represents the macroeconomic equilibrium condition in the aggregate expenditure (AE) model?Use the Keynesian cross model to predict the impact of an increase in government purchases on equilibrium GDP. State the direction of the change and give a formula for the size of the impact. An increase in taxes shifts the planned expenditure function downward. The change in income is given by AY= ΔΥ= -MPC 1-MPC An increase taxes shifts the planned expenditure function upward. The change in income is given by -MPC 1-MPC AY= XAT An increase in taxes shifts the planned expenditure function inward. The change in income is given by AY= 1 1-MPC XAT 1 1-MPC The direction of the shift is undetermined without knowing the slope of the PE function. The change in income is given by XAT XATUse the Keynesian cross to predict the impact on equilibrium GDP of the following. In each case, state the direction of the change and give a formula for the size of the impact. (solve all the three cases) An increase in government purchases An increase in taxes Equal-sized increases in both government purchases and taxes
- please answer as detailed as you can Q. What is the difference (if any) between macroeconomic equilibrium and expenditure equilibrium ?The Aggregate Expenditure Model is traditionally called the” Keynesian Cross”. Use the Aggregate Expenditure Keynesian Cross diagram to show what happens to the economy under the following conditions: (Note that is different from the AS-AD Model.) What happens in the model if government expenditures are increased (G↑)? What happens if taxes are raised (T↑)? What happens to the US economy if the rest of the world experiences economic growth and imports more US goods (X↑)?Consider an economy where the various components of expenditure follow these equations: C = 10 + 0.8Yd I = 500 G = 100 X = 300 М — 0.1Y T = 0.1Y c. Calculate the equilibrium level of GDP in this economy, highlighting what are the values of the Keynesian multiplier and the autonomous components of expenditure.
- Consider that the macroeconomy is hit by aftershocks. Exports decrease by $40 billion and imports increase by $200 billion. Modify your macroeconomic model to reflect both these aftershocks 1. At GDP of 7400: 1. Inventories are in surplus by 80 2. Inventories are in shortage by 80 3. Equilibrium is achieved by the macroeconomy according to the Keynesians 4. Inventories are in surplus by 240 2. At GDP of 8200: Inventories are in surplus by 320, Inventories are in shortage by 320, Equilibrium is achieved by the macroeconomy according to the Keynesians, or Inventories are both in surplus and shortage by 240 3. At GDP of 5000: Inventories are in surplus by 80, Inventories are in shortage by 80, Equilibrium is achieved by the macroeconomy according to the Keynesians, or Inventories are in surplus by 240 4. At GDP of 5800, exports are: 5. At GDP of 9000, imports are: 6. At the new equilibrium GDP, the economy is in: 7. The marginal propensity to consume (MPC) for your…the question is true or false: "An increase in business investment spending has the same effect on the level of ad as an increase in the same amount of government spending" can you explain what the answer is?

- Explain, in detail, how the adjustment to macroeconomic equilibrium occurs when spending is less than production. Be sure to discuss how inventories play a crucial role in the adjustment process. State what happens to GDP and employment during the adjustment process.Use the Keynesian cross to predict the impact of the following on equilibrium income. Use dia- grams and explain your intuition. 1. An increase in government purchases. 2. An increase in taxes. 3. An equal increase in both government purchases and taxes.What happens in the simple Keynesian model if households expect lower income in the future and decide to save more today? Adjust the graph and answer the question. Assume that investment varies directly with aggregate income.
