We are in eqm in the full SR model, IS-LM. Following a single shock (so that only one curve shifts), cet. par., we see that the nominal interest rate has fallen and Y has risen then we know with certainty that the Fed has engaged in expansionary policy. True, False, or Uncertain? Show graph in i-Y space and explain fully.
The Keynesian Transmission mechanism will eliminate a recessionary gap if there are not Liquidity Trap or Insensitive Investment function. Explain:a) What it is a liquidity trapb) What it is insensitive investment function
b) use the "Lucas Island Model" to provide an explanation as to why money is leading and pro-cyclical according to the New Classical Economists. Be sure to include a completely labeled AS/AD diagram and an explanation of what we mean exactly by a Lucas Aggregate supply curve (along with the intuition underlying it). Finish your essay by discussing whether or not money is neutral in this New Classical model and why. ANSWER I WROTE The Lucas Island Model retains the assumption of rapid market clearing despite being based on incomplete information. The Lucas Island Model makes the same assumption as the traditional model that the money supply will rise before prices start to rise. Take a person, let's say a tailor. After observing the fabric market for some time, the tailor detects a rise in the cost of cloth. He believes that the relative price of cloth has increased because he is unaware of what has occurred to the prices of all other commodities, which is what we refer to as price…
In the full SR model, IS-LM, we know that if to falls, cet. par., then the real Money Supply will increase. True, False, Uncertain? Explain. Show graphs in i-Y space and i-M/P spaces.
Explain in words how investment multiplier and the interest sensitivity of aggregate demand affect the slope of the IS curve. Furthermore, Explain in words how and why the income and interest sensitivities of the demand for real balances affect the slope of the LM curve. According to the IS–LM model, what happens to the interest rate, income, consumption, and investment under the following circumstances?a. The central bank increases the money supply.b. The government increases government purchases.c. The government increases taxes.
Consider the following numerical example of the IS-LM model: C = 200 + 0.25YD I = 150 + 0.25Y - 1000iG = 250 T = 200 i = .05 a. Derive the IS relation. (Hint: You want an equation with Y on the left side and everything else on the right.) b. The central bank sets an interest rate of 5%. How is that decision represented in the equations? c. What is the level of real money supply when the interest rate is 5%? Use the expression:(M>P) = 2Y - 8000i d. Solve for the equilibrium values of C and I, and verify the value you obtained for Y by adding C, I, and G. e. Now suppose that the central bank cuts the interest rate to 3%. How does this change the LM curve? Solve for Y, I, and C, and describe in words the effects of an expansion-ary monetary policy. What is the new equilibrium value of M/P supply? f. Return to the initial situation in which the interest rate set by the central bank is 5%. Now suppose that government spending increases to G = 400. Summarize the effects of an expansionary…
Consider the following short-run IS-LM model. Assume the central bank targets the nominal interest rate and expected inflation is zero. C = 300 + .50YD I = 1000 + .10Y – 5000i G = 700 T = 600 M/P = 100 + .25Y - 6250i P = 1 i = .06 Y-T = YD Solve for the IS equation and the LM equation. Find the equilibrium and also show it on a graph of IS-LM. Find the equilibrium values for C, I, and the money supply M. Consider a fiscal stimulus: what is the impact on Y if G rises by 100? What is the impact on I in this case? What is the impact on the interest rate and the money supply? Return to your original analysis. Consider a monetary stimulus where the central bank sets a new target interest rate, i = .04. Find the new equilibrium values for Y, C, and I. Find and discuss any change in the money supply. What causes the change in I in this case? Explain.
Assume that as a consequence of an IS shock the economy is initially at a point with output above equilibrium (y > ye), and inflation of 4% above a 2% target. By means of a diagram, explain how the central bank will respond to this new information about economic conditions and discuss the effects on the economy.
Consider the following numerical example of the IS-LM model: C = 200 + 0.25YD I = 150 + 0.25Y - 1000i G = 250 T = 200 i = .05 (i has a bar over it) a. Derive the IS relation. (Hint: You want an equation with Y on the left side and everything else on the right.) b. The central bank sets an interest rate of 5%. How is that decision represented in the equations? c. What is the level of real money supply when the interest rate is 5%? Use the expression:(M>P) = 2Y - 8000i d.

Using the IS LM model, show how expansionary monetary and expansionary fiscal have same effect on output but opposite impact on interest rates. b. Derive the equations for IS and LM curves from the set of equations given below: C = 80+ 0.75Yd I = 300-200 i G is government expenditure G = 30 T = 30 where T= taxes Ms = 270 where Ms is money supply Md = 150+ 0.30Y – 300i Find the volume of investment at equilibrium . What would be the impact on investment if Money supply is increased to 300.
Suppose the economy is initially in its long-run equilibrium. Due to the biased (overestimated) expectation of return, the entrepreneurs overwhelmingly become much more aggressive in investment holding other things equal. a. Use the IS-LM model and AD-AS model to graphically illustrate the impact of the biased expectation in the short run and in the long run. What are the changes in the equilibrium real interest rate, output, and prices? b. If the central bank wants to offset the impact of the biased expectation, what is the appropriate measure? Draw a graph as in part a. for illustration. What are the changes in the equilibrium real interest rate, output, and prices in this case?
Explain the effect, if any, that each of the following occurrencesshould have on the aggregate demand curve.a. The Fed lowers the discount rate.b. The price level decreases.c. The federal government increases federal income tax rates inan effort to reduce the federal deficit.d. Pessimistic firms decrease investment spending.e. The inflation rate falls by 3 percent.f. The federal government increases purchases to stimulatethe economy.
