Using monetary policy to raise the real interest rate leads to an ______ in investment spending and an ______ in consumption spending. a) increase, increas

Consider a closed economy in which: C=250+0.8 (Y-T)I=400−30 rT=150G=220Y=C+I+G where Y is GDP, C is consumption, I is investment, T is taxes, G is government purchases, and r is the interest rate. If the economy were at full employment (that is, at its natural rate), GDP would be 3,000.  a. Suppose the central bank’s policy is to adjust the money supply to maintain the interest rate at 3 percent, so r = 3. Solve for GDP (Y). Y=______ b. How much is the private saving (SPVT)? SPVT=______ c. How much is the government spending multiplier (k)? k=______  d. Assuming no change in monetary policy, what change in government purchases (ΔG) would restore full employment? ΔG=______ e. Assuming no change in fiscal policy, what change in the interest rate (Δr) would restore full employment? Δr=______

Why will a reduction in the real interest rate increase investment spending, other things equal? Why is investment spending unstable?

If all of the households and businesses in the economy start saving more during economic hard times, then aggregate income will fall, hurting everyone in the economy. This is known as: A) the quantity theory. B) the crowding-out theory. C) the paradox of thrift. D) the permanent income hypothesis

Macroeconomics Question No.4 Using the IS–LM diagram, show the effects on output and the interest rate of a decrease in government spending. Can you tell what happens to investment? Why? Using the IS–LM diagram, show the effects on output and the interest rate of a decrease in money supply. Can you tell what happens to investment? Why?

true or false and provide a reason to support it, please quickly thanks !!! Q9.Keynes believed that saving is less responsive to changes in income than to changes interest rates

As interest rates rise, the effect on aggregate demand is to Select one: a. increase firm borrowing and investment spending. b. increase only firm borrowing. c. reduce consumer borrowing and consumption spending. d. increase consumer borrowing and saving.

An economy is described by the following equations: C = 2,600+ 0.8 (Y- T) - 10,000r IP = 2,000 10,000r G = 1,800 NX = 0 T = 3,000 The real interest rate, expressed as a decimal, is 0.10 (that is, 10 percent). a. Find a numerical equation relating planned aggregate expenditure to output. Instructions: Enter your response for mpc rounded to one decimal place. PAE=+ 0.8 Y b. Using a table (or algebra if you have used the appendix to this chapter), solve for short-run equilibrium output. Instructions: If you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers. Leave no cells blank. You must enter 'zero' for the answer to grade correctly. Output Y 9,500 9,600 9,700 9,800 9,900 10,000 10,100 10,200 Planned aggregate expenditure (PAE) Short-run equilibrium output: Y PAE

New money injected in the economy will have a multiplied effect on the macro-economy.    True  False

Suppose the incoming Biden administration permanently increases taxes and government purchases by equal amounts. 1)What will be the impact (if any) on output in the short run? 2)What will be the impact on the economy’s normal real interest rate (r*) and normal investment (I*, which is the same as normal saving, S*)?
