15. The late 1990s in the United States were characterized by substantial economic growth with low inflation; that is, real GDP increased with little, if any, increase in the aggregate price level. Explain this experience using aggregate demand and aggregate supply curves. Illustrate with a diagram.

9. Problems and Applications Q3 Suppose an economy is in long-run equilibrium. The central bank raises the money supply by 5 percent. Use your diagram to show what happens to output and the price level as the economy moves from the initial to the new short-run equilibrium. Price Level LRAS Aggregate Supply Aggregate Demand Quantity of Output Aggregate Demand 10 Aggregate Supply Now adjust the graph to show the new long-run equilibrium. What causes the economy to move from its short-run equilibrium to its long-run equilibrium? Nominal wages, prices, and perceptions adjust upward to this new price level. The government increases taxes to curb aggregate demand. The government increases spending to increase aggregate demand. Nominal wages, prices, and perceptions adjust downward to this new price level. According to the sticky-wage theory of aggregate supply, nominal wages at the initial equilibrium are nominal wages at the short-run equilibrium resulting from the increase in the money…

6. Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output that firms supply can deviate from the natural level of output if the actual price level in the economy deviates from the expected price level. Several theories explain how this might happen. For example, the sticky-wage theory asserts that output prices adjust more quickly to changes in the price level than wages do, in part because of long-term wage contracts. Suppose a firm signs a contract agreeing to pay its workers $15 per hour for the next year, based on an expected price level of 100. If the actual price level turns out to be 90, the firm's output prices will , and the wages the firm pays its workers will remain fixed at the contracted level. The firm will respond to the unexpected decrease in the price level by v the quantity of output it supplies. If many firms face similarly rigid wage contracts, the unexpected decrease in the price level causes the quantity of output…
