tax. Using relevant Classical Theories, explain its long-run effects on savings,
real interest rates,s and investments.
Question no 2

concern of plausible supply chain issues, business firms in Country A tend to
increase their level of inventory.
Using relevant Classical Theories, explain how this would affect her net

- During the current economic crisis caused by COVID 19, the Australian authorities have used both monetary and fiscal policy to try and minimise unemployment. (a) Use the dynamic AD-AS model to describe the impact of the crisis on the economy. Be sure to comment on its effect on both the demand and supply side in your answer. b) Using the same model, discuss and show in a diagram how the correct fiscal policy may offset the impact of the COVID effects on the economy. Be sure to mention any practical issues that may modify your answeronsider a closed economy to which the Keynesian-cross analysis applies. Consumption is given by the equation C = 200 + 2/3(Y – T). Planned investment is 300, as are government spending and taxes. What is equilibrium Y? (Hint: Substitute the values of equations for planned consumption, investment, and government spending into the equation Y = C + I + G and then solve for Y.) What are equilibrium consumption, private saving, public saving, and national saving?Consider an economy described by the following data:C = $3.25 trillionI = $1.3 trillionG = $3.5 trillionT = $3.0 trillionNX = - $1.0 trillionf = 1mpc = 0.75d = 0.3x = 0.1a. Derive simplified expressions for the consumptionfunction, the investment function, and the net exportfunction.b. Derive an expression for the IS curve.c. If the real interest rate is r = 2, what is equilibriumoutput? If r = 5, what is equilibrium output?d. Draw a graph of the IS curve showing the answersfrom part (c) above.e. If government purchases increase to $4.2 trillion,what will happen to equilibrium output at r = 2?What will happen to equilibrium output at r = 5?Show the effect of the increase in government purchases in your graph from part (d).
- Elaborate on the difference between a binding and non-binding borrowing constraints and thetwo consumption functions that result.b. From the Intertemporal Choice Model, many theories (non-Keynesian theories ofConsumption) came into being. Using graphical and mathematical expressions, compareand contrast the following theories on consumption behaviours:i. Franco Modigliani: Life-Cycle Hypothesisii. Milton Friedman: Permanent-Income Hypothesisiii. Robert Hall: Random Walk HypothesisConsider a keynesian macromodel Y=(C0+G+I) / (1-c) where C0 is autonomus consumption, G is government consumption expenditure, I is investment expenditure, c is the marginal propensity to consume. In this model, if lthere is an increse in both labor productivity and the marginal propensity to consume while autonomus expenditures remain unchanged, what will happen to the level of employment? a. can't say for sure b. decreses c. stays the same d. increasesCongratulationst You have been appointed an economic policy adviser to the United States, You are told that the economy is significantly abowe futtemplyoment GDP. Based on this inlormation, how can the economy would adjust to reach LR.SR Equilbrium (Classical View)? The economy wilt experience low unemployment rate, pushing wages up, and increasing the pelces of a key input (labor). shatting the sAS to the left (up). The economy will experience high unemployment rate, pushing wages down, and reducing the prices of a key input (labor). shiting the SAS to the right (down). The econoriny wil experience low unemployment rate, decreasing inceme, which will eventually shift the AD to the left. The eooncmy will experience low unemployment rate, pushing wages up, and increasing the prices of a key input (labor), shiting the sAs to the night (down).

- The US Government is facing major budget deficit deciding between implementing fiscal and monetary policy to boost output back to potential output. In the presence of expectations, using the IS-LM model graph the effects on the US economy from a contractionary fiscal policy? What would happen if this change is perceived as permanent by investors? Graph and explain. What would happen if the government was perceived as wasteful? Graph and explain.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 PAE = C+1²+ GANX T = 3,000, Where the definitions of each variables are the same as our lecture notes. The real interest rate, r, expressed as a decimal, is 0.10 (that is, 10 percent). a. Find a numerical equation relating planned aggregate expenditure to output. b. Solve for short-run equilibrium output. c. Show your result graphically using the Keynesian-cross diagram. d. Now, suppose that potential output Y* equals 12,000. What real interest rate should the Fed set to bring the economy to full employment? e. Recalculate question (d) for the case in which potential output Y* equals 9,000.1. Consider an economy where the potential output is equal to the equilibrium output (i.e., 7 =Y) and the country is running a budget deficit (i.e., G>T). Suppose that the households in this economy become very thrifty. a. Using the IS-LM model, illustrate (draw a graph) and explain what happens to r and Y due to increasing thriftiness. b. If the government wants to stabilize output Y at its potential Y and balance the budget at the same time, illustrate (Draw a graph ) and explain what combination of monetary and fiscal policies should be implemented.
