**15. Distinguish between demand-pull inflation and cost-push inflation. Which of the two types is most likely to be associated with a (negative) GDP gap? Which with a positive GDP gap, in which actual GDP exceeds potential GDP?**Demand-pull inflation occurs when prices rise because of an increase in aggregate spending not fully matched by an increase in aggregate output. It is sometimes expressed as “too much spending (or money) chasing too few goods.”Cost-push inflation describes prices rising because of increases in per unit costs of production.Cost-push inflation is most likely to be associated with a negative GDP gap, as the rising production costs reduce spending and output.Demand-pull inflation is more likely to occur with a positive GDP gap, because actual GDP will exceed its potential only when aggregate spending is strong and rising. As the economy produces above its potential, bottlenecks and more severe resource scarcity occur, driving up prices.

The difference between cost-push and demand-pull inflation is that for cost-push inflation, costs…

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-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 90. Faced with high menu costs, the firms that rely on catalog sales choose not to adjust their prices. Sales from catalogs will v , and firms that rely on catalogs will respond by v the quantity of output they supply. If enough firms face high costs of adjusting prices, the unexpected…
22. When the aggregate demand curve and the short-run aggregate supply curve intersect, A) the long-run aggregate supply curve must also intersect at the same point. B) inflation must be increasing. C) structural and frictional unemployment equal zero. D) the economy is in short-run macroeconomic equilibrium. 23. Interest rates in the economy have fallen. How will this affect aggregate demand and equilibrium in the short run? A) Aggregate demand will rise, the equilibrium price level will rise, and the equilibrium level of GDP will rise. B) Aggregate demand will rise, the equilibrium price level will fall, and the equilibrium level of GDP will rise. C) Aggregate demand will fall, the equilibrium price level will fall, and the equilibrium level of GDP will fall. D) Aggregate demand will fall, the equilibrium price level will rise, and the equilibrium level of GDP will fall.
5. The stock market crash has caused a great number of asset prices to drop sharply.If people’s expectation on current inflation level remain unchanged, what wouldbe the effects of this crisis to inflation and unemployment? Explain and useappropriate diagrams to support your answer.
Consider the figure to the right. If this country's government decides to increase its short-term spending, what happens to the short-run equilibrium price level, and why? Is this an example of demand-pull or cost-push inflation? Explain. 1.) Using the line drawing tool, draw either a new aggregate demand (AD) curve or a new short-run aggregate supply (AS) curve that shows the effects of temporary government spending increases. Properly label your line. 2.) Using the point drawing tool, indicate the economy's new short-run equilibrium price and level of real GDP. Label this point 'E₂.' Carefully follow the instructions above, and only draw the required objects. Price Level LRAS₁ Real GDP per Year (S trillions) AS₁ AD₁
6. Aggregate demand, aggregate supply, and the Phillips curve In the year 2023, aggregate demand and aggregate supply in the fictional country of Bartak are represented by the curves AD2023 and AS on the following graph. The price level is 102. The graph also shows two possible outcomes for 2024. The first potential aggregate demand curve is given by the ADA curve, resulting in the outcome illustrated by point A. The second potential aggregate demand curve is given by the ADB curve, resulting in the outcome illustrated by point B. 108 107 AS 106 B 105 A 104 AD 2023 103 AD. 102 AD 101 100 2 4 6 8 10 12 14 16 OUTPUT (Trillions of dollars) Suppose the unemployment rate is 7% under one of these two outcomes and 5% under the other. Based on the previous graph, you would expect to be associated with the higher unemployment rate (7%). If aggregate demand is low in 2024, and the economy is at outcome A, the inflation rate between 2023 and 2024 is PRICE LEVEL
4. Suppose that the President and Congress get legislation passed that encourages investment in research and development of new technologies. Assuming this policy results in a positive and permanent technological change, what does aggregate demand and supply analysis predict in terms of inflation and output? Only consider the self- correcting mechanism of the economy.
9. How will (a) an unexpected 3 percent fall in the price level in the goods and services market differ from (b) 1 percent inflation when 4 percent inflation had been expected? What impact would (a) and (b) have on the real price of resources, profit margins, output, and employment? Explain.
2. The inflation-unemployment relationship The following graph shows the combinations of unemployment and inflation that existed in the United States for selected years between 1961 and 1969. Click on any blue point (circle symbol) on the graph to get its exact coordinates. You can also use the black point (cross symbol) to find the coordinates of other points along the curve. (Note: You will not be graded for any adjustments made to the graph.) INFLATION RATE (Percent) 1969 5.2 4.5 1988 85 1967 20 1.5 10 0.5 1960 1984 1963 1981 0 2.0 3.5 40 4.5 5.0 5.5 GO 4.5 7.0 UNEMPLOYMENT RATE (Percent)
9. Money Supply 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. RANDO LHAS Aggregale Supply * A Demand Quantity of Oulpul Now adjust the graph to show the new long-run equilibrium. Aggregate and - Aggregate Supply What causes the economy to move from its short-run equilibrium to its long-run equilibrium? The government increases taxes to curb aggregate demand. The government increases spending to increase aggregate demand. O Nominal wages, prices, and perceptions adjust downward to this new price level. O Nominal wages, prices, and perceptions adjust upward to this new price level. Which of the following is true according to the sticky-wage theory of aggregate supply as a result of the increase in the money supply? Check all that apply. Nominal wages at the initial equilibrium are equal to…
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…
