Question 2: [50 marks] The COVID-19 pandemic is causing tremendous hardship around the world. A recession, likely a severe one, is inevitable. A. Show the short run effects of a decrease in the demand for goods and services caused by the pandemic. Suppose the economy is an open economy that is on a flexible exchange rate. To answer this question, draw the following five diagrams: 1. The goods market, [3 marks] 2. The money market, [3 marks] 3. The IS-LM...

Using the IS-LM and Aggregate Supply-Aggregate Demand (AS-AD) models of Chapter 12 with a flat short-run AS curve (that is, completely sticky prices), suppose the economy is at the natural rate of unemployment and so, at long-run equilibrium. Suddenly, taxes are reduced with no change in government spending. Tell me (or show on a graph) what happens to the IS and/or LM curves. Show on a different graph what happens on the AS-AD diagram in the short-run (drawing in the...

Question 5: [15 marks A. In an open economy that is on a fixed exchange rate, show the short run effects on output and interest rate of a decrease in consumer confidence. To answer this question, draw the following four diagrams: 3 1. The goods market, 2. The money market, 3. The IS-LM curves, and 4. The interest parity condition. Clearly label the initial and new equilibrium points in each diagram. Provide brief explanations for the changes.

3. Suppose the economy originally operates at medium run equilibrium. Now, consumer confidence suddenly increased. a) In ISLM and ADAS diagrams, show the effect of the increase in consumer confidence in the short run and in the medium run, on output, nominal interest rate, and price level. Briefly explain the shift of curves. b) Based on your answer in (a), explain what happens to private savings in the short run. (Hint: S=Y-T-C=Y-T-c0-c1(Y-T)= -c0+(1-c1)(Y-T) ) c) What happens to private savings...

Suppose that Congress is going to increase government purchases on a permanent basis. Use the IS-LM/AS-AD tools to analyze the implications in the short run and in the long run. (Assume the following. Prices are completely fixed in the short run and completely flexible in the long run. Taxes remain constat. Consumption is a function of disposable income, with a constant marginal propensity to consume. Investment is a function only of interest rate. Our starting point in full equilibrium output.)...

According to the IS-LM model, what happens in the short run to the interest rate, income, consumption, and investment under the following circumstances?

please answer Question 7:
Inflation targeting and the Taylor rule in the IS-LM model Consider a closed economy in which the central bank follows an interest rate rule. The IS relation is given by Y C(Y- T) I(Y,r) G Where r is the real interest rate. The central bank sets the nominal interest rate according to the rule i = i* + a(n° =- T*) + b(Y- Y1) Where T is expected inflation, T* is the target rate of inflation,...

one big problem. thank you!!
Problem 3: AS-AD Relation Part II (20pts) AS-AD model can be used to explain how the economy transitions from the short-run to the medium-run 3a. (1pt) Can price be higher than expected price in the short run? 3b. (1pt) if P> Pe in the short run, what happens to Pe when we go from short-run to medium-run? 3c. (2pt) If Pe increases, would AD curve shift or would AS curve shift? How would it shift?...
