The following graph shows an increase in short-run aggregate supply (AS) in a hypothetical economy where the currency is the dollar. Specifically, the short-run aggregate supply curve shifts to the right from AS₁ to AS2, causing the quantity of output supplied at a price level of 100 to rise from $200 billion to $250 billion. PRICE LEVEL 200 175 150 125 100 75 50 25 I I AS₁ AS₂ ?

2. The theory of liquidity preference and the downward-slopingaggregate demand curve Suppose the money market for some hypothetical economy is given by the following graph, which plots the money demand and money supply curves. Assume the central bank in this economy (the Fed) fixes the quantity of money supplied. Suppose the price level increases from 90 to 105. Shift the appropriate curve on the graph to show the impact of an increase in the overall price level on the market for money. INTEREST RATE (Percent) 18 15 12 8 3 0 0 20 Money Supply Money Demand 40 60 80 MONEY (Billions of dollars) 100 120 Money Demand Money Supply Following the price level increase, the quantity of money demanded at the initial interest rate of 9% will be supplied by the Fed at this interest rate. As a result, individuals will attempt to bonds and other interest-bearing assets, and bond issuers will realize that they restored in the money market at an interest rate of % than the quantity of money their money…

The following graph shows a hypothetical economy in long-run equilibrium at an expected price level of 120 and a natural output level of $300 billion. Suppose a stock market boom increases household wealth and causes consumers to spend more. Using the graph, shift the short-run aggregate supply (AS) curve or the aggregate demand (AD) curve to show the short-run impact of the stock market boom. PRICE LEVEL 3 AS 200 AD -α- 180 8 0 100 200 300 AD 400 500 600 OUTPUT (Billions of dollars) AS (?) In the short run, the increase in consumption spending associated with the stock market expansion causes the price level to level people expected and the quantity of output to the price the natural level of output. The stock market boom will cause the unemployment rate to ▼the natural rate of unemployment in the short run. Again, the following graph shows a hypothetical economy experiencing long-run equilibrium at the expected price level of 120 and natural output level of $300 billion, prior to the…

One of the reasons given for the downward sloping aggregate demand curve is the foreign price effect.  Clearly explain, step by step, how an increase in the price level will lead to a decrease in the aggregate demand, indicating a downward sloping aggregate demand curve.
