Suppose the aggregate demand and short-run aggregate supply schedules for an economy whose potential output equals $2,700 are given by the table: Aggregate Quantity of Goods and Services Price Level Demanded Supplied 0.50 $3,500 $1,000 0.75 3,000 2,000 1.00 2,500 2,500 1.25 2,000 2,700 1.50 1,500 2,800   What is the size of the recessionary gap?

6. Macroeconomic equilibrium and the ranges of the aggregate supply curve The following graph shows the aggregate demand (AD₁) and aggregate supply (AS) curves for a hypothetical economy with Natural Real GDP of $11 trillion. ? The Simple Keynesian Model AD₁ 130 125 120 115 110 105 100 95 90 8.0 8.5 9.0 11.5 12.0 9.5 10.0 10.5 11.0 REAL GDP (Trillions of dollars) Suppose consumers and businesses become less optimistic about future economic conditions, causing aggregate demand to decrease by a total $1.5 trillion at each price level (after all multiplier effects have taken place). On the previous graph, use the green line (triangle symbol) to show the new aggregate demand curve (AD2). Be sure that AD2 is parallel to AD₁ (you can mouse over AD₁ to see its slope). Then use the black drop lines (cross symbol) to indicate the new macroeconomic equilibrium after the shift of aggregate demand. range of the aggregate supply curve, causing the equilibrium price The decrease in aggregate demand…

Suppose that firms become very pessimistic about future business conditions and cut heavily on investment in capital equipment. [Label A, B, C for the initial, new short-run and new long-run equilibrium respectively] a)Use an aggregate-demand/aggregate-supply model to show the short-run effect of this pessimism on the economy. Label the new levels of prices and real output. Explain in words why the aggregate quantity of output supplied changes. (Use the sticky wage theory in your explanation)

Which of the following will increase the Aggregate Demand curve or shift it to the right? The government passes a big infrastructure improvement spending bill O Interest rates rise The raises personal income taxes The U.S. population experiences a significant contraction in population, decreasing the number of people working and consuming. Question 2 Which of the following will decrease the aggregate supply curve or shift it to the left? New international sanctions on Iranian oil raise the price of oil globally and oil is an input in production of many goods and services A 10 percent across the board reduction in personal income tax rates Business taxes fall A new networking technology increases productivity all over the economy

how should I answer this?

In this aggregate demand model, which one of the following statements correctly describes the economy if it is at point Y on the diagram? 1 - The economy is at the full employment equilibrium 2- There are forces that are tending to make income (output) fall. 3-There are forces that are tending to make income (output) rise. 4-The economy is in equilibrium at less than full employment.

11. Recession True or False: The aggregate-demand curve slopes downward because it is the horizontal sum of the demand curves for individual goods. True False

# I am guessing, the price of imports will decrease is wrong.

8. Economic fluctuations I The following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion. Suppose the government increases spending on building and repairing highways, bridges, and ports. Shift the short-run aggregate supply (AS) curve or the aggregate demand (AD) curve to show the short-run impact of the increase in government spending. 240 AS 200 AD 160 AS 120 80 AD 40 200 400 600 800 1000 1200 OUTPUT (Billions of dollars) In the short run, the increase in government spending on infrastructure causes the price level to the price level people expected and the quantity of output to the natural level of output. The increase in government spending will cause the unemployment rate to the natural rate of unemployment in the short run. Again, the following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion, before the increase in…

7. The long-run aggregate supply curve and short-run adjustments Suppose an economy's short-run aggregate supply curve (SRAS), current equilibrium aggregate price level (P₁), and real GDP (Q1) are shown on the graph that follows. The economy currently has Natural Real GDP (QN) of $6 trillion. Use this information to place the orange long-run aggregate supply curve (LRAS, square symbols) in the correct position on the graph. 20 PRICE LEVEL 0 2 4 6 Q₁ REAL GDP (Trillions of dollars) 8 SRAS 10 LRAS
