For the linear IS-LM model, the goods market and the money market are in equilibrium when. Suppose that the economy is characterized by the following equations: (Y;r) = ( 1200 ; 6), Y-C-IG=0, C-Co-c(Y-T)=0,I-Io+hr=0, and kY-ur-M^s=0, which are satisfied for Co=60, lo=150, G=250, T=200, M^s=60, with the parameters c=0.8, k=0.1, h=10, and u=10. How are the equilibrium
and affected,
a) if "h" (the sensivity of the demand for investment to the interest rate) decreases to 5?
b) if "u" (the sensitivity of the demand for real money balances to the interest rate) decreases to 5?
Suppose that a hypothetical economy has the following relationship between its real output and the input quantities necessary for producing that output: a. What is productivity in this economy?b. What is the per-unit cost of production if the price of each input unit is $2?c. Assume that the input price increases from $2 to $3 with no accompanying change in productivity. What is the new per-unit cost of production? In what direction would the $1 increase in input price push the economy’s aggregate supply curve? What effect would this shift of aggregate supply have on the price level and the level of real output?d. Suppose that the increase in input price does not occur but, instead, that productivity increases by 100 percent. What would be the new per-unit cost of production? What effect would this change in per-unit production cost have on the economy’s aggregate supply curve? What effect would this shift of aggregate supply have on the price level and the level of real output?
Suppose that the aggregate demand and aggregate supply schedules for a hypothetical economy are as shown below: a. Use these sets of data to graph the aggregate demand and aggregate supply curves. What is the equilibrium price level and the equilibrium level of real output in this hypothetical economy? Is the equilibrium real output also necessarily the full-employment real output? Explain.b. Why will a price level of 150 not be an equilibrium price level in this economy? Why not 250?c. Suppose that buyers desire to purchase $200 billion of extra real output at each price level. Sketch in the new aggregate demand curve as AD1. What factors might cause this change in aggregate demand? What is the new equilibrium price level and level of real output?

- 42. Suppose that there is a temporary fall in aggregate supply due to a drought. Whathappens in the long-run?(A) Higher prices cause permanent tensions, leading long-run aggregate supply to shiftleft, resulting in a lower natural rate of output.(B) Over time, as the drought conditions fade, aggregate supply rises and returns tothe original natural rate of output.(C) Aggregate demand shifts right, so that prices are higher but long-run output isunchanged.(D) If the person you’re dating enjoys Taylor Swift, dump them immediatelyarrow_forwardOver the last couple of years, food prices have increased substantially. Present two separate supply-demandanalyses to explain why the observed price increases could come from two fundamentally different causes.In one of your analyses, show that some “negative supply side shock”, like the Covid lockdowns that disruptedsupplies of goods and services, could have caused the observed increase in prices. In your other analysis,show that some “positive demand side shock”, like the large increases in government spending associatedwith Covid, could have caused the observed increases in prices. For full credit, identify how the results of thetwo analyses differ, and explain how you could use that difference to decide which type of shock was moresignificant in terms of explaining the observed price increases.arrow_forwardSuppose that consumer spending initially rises by $5 billion for every 1 percent rise in household wealth and that investment spending initially rises by $20 billion for every 1 percentage point fall in the real interest rate.
