Chapter 20 Homework 1 Suppose the natural level of output is $50 billion of real GDP and that people expect a price level of 105. On the following graph, use the purple line (diamond symbol) to plot this economy's long-run aggregate supply (LRAS) curve. Then use the orange line segments (square symbol) to plot the economy's short-run aggregate supply (AS) curve at each of the following price levels: 95, 100, 105, 110, and 115. PRICE LEVEL 125 120 115 110 105 100 95 90 85 80 75 0 10 20 30 40 50 60 70 OUTPUT (Billions of dollars) 80 90 100 AS LRAS The short-run quantity of output supplied by firms will fall short of the natural level of output when the actual price level level that people expected. the price

6. Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output supplied by firms can deviate from the natural level of output if the actual price level deviates from the expected price level in the economy. A number of theories explain reasons why this might happen. For example, the sticky-price theory asserts that the output prices of some goods and services adjust slowly to changes in the price level. Suppose firms announce the prices for their products in advance, based on an expected price level of 100 for the coming year. Many of the firms sell their goods through catalogs and face high costs of reprinting if they change prices. The actual price level turns out to be 110. Faced with high menu costs, the firms that rely on catalog sales choose not to adjust their prices. Sales from catalogs will not change, and firms that rely on catalogs will respond by lowering the quantity of output they supply. If enough firms face high costs of…

On the following graph, use the purple Mine (diamond symbol) plot this economy's long-run aggregate supply (LRAS) curve. Then use the orange ne segments (square symbol) to plat the economy's shart-run aggregate supply (AS) curve at each of the following price levels: 100, 105, 110, 115, and 120, PRICE LEVEL 116 110 105 100 80 75 0 + 10 20 30 40 90 70 OUTPUT (ons of dollars) 85 120 AS LRAS The short-run quantity of output supplied by firms will fall short of the natural level of output when the actual price level level that people expected. the price

The short-run quantity of output supplied by firms will exceed the natural level of output when the actual price level ———-that people expected.

The following graph plots aggregate demand (AD2027AD2027) and aggregate supply (AS) for the imaginary country of Cotopaxi in the year 2027. Suppose the natural level of output in this economy is $6 trillion.   On the following graph, use the green line (triangle symbol) to plot the long-run aggregate supply (LRAS) curve for this economy.   Economists forecast that if the government takes no action and the economy continues to grow at the current rate, aggregate demand in 2028 will be given by the curve labeled ADAADA, resulting in the outcome given by point A. If, however, the government pursues an expansionary policy, aggregate demand in 2028 will be given by the curve labeled ADBADB, resulting in the outcome given by point B. The following table presents projections for the unemployment rates that would occur at point A and point B. Consider the potential rate of inflation between 2027 and 2028, depending on whether the economy moves from the initial price level of 102 to the…

On the following graph, use the purple line (diamond symbol) to plot this economy's long-run aggregate supply (LRAS) 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 decreases from 150 to 125. Shift the appropriate curve on the graph to show the impact of a decrease in the overall price level on the market for money. Money Supply 15 12 4 Money Demand 3 5 10 15 20 MONEY (Billions of dollars) INTEREST RATE (Percent) 18 0 0 25 30 Money Demand Money Supply (?) Following the price level decrease, 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 holdings. In order to do so, they will interest rates until equilibrium is
