Question 1:

Use the model of aggregate demand and short-run aggregate supply to explain how each of the following would affect real GDP and the price level in the short run.

An increase in government purchases
A major decrease in the stock of capital
A trade surplus
An increase in Labor

This is the whole question and I need these answers with the graph, please... Thank you!

In short run the AS curve is flat.

1. If there is an increase in Govt purchases. The AD curve will shift up. Which leads to increase in Real GDP as prices are constant.

2. IA major decrease in the stock of capital

A major Decrease in stock of capital means, people do not have enough money in their hand to buy. Hence AD will shift leftwards. Leading to a decrease in Real GDP. The output decreases from Y0 to Y1.

3. A trade surplus means, there is a lot to buy . Hence Demand will shitt upwards, leading to an increase in output from Y0 to Y1.

4. If there is an increase in Labour, it means that people have more income in their hands to buy,Hence the demand curve wll shift upward leading to an increase in real GDP.

It is concluded that in the short run, output is determined by the AD alone and prices are unaffected by the level of output.

1. Using the aggregate demand (AD), the short-run aggregate supply (SRAS), and the long-run aggregate supply (LRAS) curves, briefly explain how an open market purchase will affect the equilibrium price level (P) and real output (Y) in the short run. Assume the economy is initially in a recession. 2. Using the quantity equation (the equation of exchange) briefly explain the quantity theory of money. Specifically, how the quantity theory of money explains why inflation occurs.

Using aggregate demand, short-run aggregate supply, and long-run aggregate supply curves, explain the process by which each of the following government policies will move the economy from one long-run macroeconomic equilibrium to another. Illustrate with diagrams. In each case, what are the short-run and long-run effects on the aggregate price level and aggregate output? There is an increase in taxes on households. There is an increase in the quantity of money. There is an increase in government spending.

Using aggregate demand, short-run (SR) aggregate supply, and long-run (LR) aggregate supply curves, explain the process by which each of the following economic events will move the economy from an original LR (and SR) equilibrium (eq) to a new SR eq, and to a new LR (and SR) eq. Illustrate with diagrams. There is a decrease in households’ wealth due to a decline in the stock market. The government lowers taxes, leaving households with more disposable income.
