In the long run, when the government pursues accommodative policy, the output in the economy will be $ billion and the price level will be PRICE LEVEL

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.

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 total expenditure in Macroland begins with these initial levels (in trillions of dollars): autonomous consumption=1, Investment = 2; Net Exports = 0, T=2, and MPC = 0.75. Assume that equilibrium has been achieved. Suddenly there is an external shock and as a result investment goes down to 1. What is the change in GDP? Use the base model to answer this question. Equilibrium GDP goes down by 1 Equilibrium GDP goes up by 1 Equilibrium GDP goes up by 4 Equilibrium GDP goes down by 4

Identify how each of the following changes will affect Aggregate Demand An increase in consumers disposable income A decrease in Investment spending due to pessimistic forecasts concerning the future A global pandemic resulting in business closures and an increase in the unemployment level The federal government increases spending on roads, bridges, and school repairs The federal government reduces the federal income tax resulting in an increase in household disposable income

Which of the following states is equivalent to saying that we are in a short-run equilibrium? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a There is no unplanned changes in inventories. b Investment (I) is equal to Planned Investment Spending (Ip). Income is equal to aggregate expenditures. d All of the above.

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.

Suppose AE = 0.50 Y + 500. If GDP = $1,000, and There will be excess supply, so inventory will accumulate and firms will reduce output next period. There will be excess demand, so inventory will shrink and firms will increase output next period. There will be neither excess demand nor excess supply, so Y = $1,000 is the equilibrium level of GDP.

Consider a fictional economy that is operating at its long-run equilibrium. The following graph shows the aggregate demand (AD) curve and short-run aggregate supply (AS) curve for the economy. The long-run aggregate supply curve is represented by a vertical line at the potential GDP level of $6 trillion. The economy is initially producing at potential GDP. Suppose that fiscal authorities decide to decrease marginal tax rates. Assume that this change in marginal tax rates is perceived as a long-term change. Shift the appropriate curves to illustrate the supply-side view of the fiscal policy effect on output and the price level. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther. 120 Potential GDP AS 100 PRICE LEVEL 60 80 60 40 40 20 20 0 0 2 4 6 8 AD 10 12 QUANTITY OF OUTPUT (Trillions of dollars) AD 1 AS Potential GDP True or…

The population has aged and there are fewer people in the labor force. Firms and workers expected the price level to rise. The economy experienced an increase in government spending. The economy was in an expansion and has adjusted. The country's overall productivity increased.
