What is a potential problem with a temporary tax increase designed to increase aggregate demand it people know that it is temporary?
Although our development of the Keynesian cross in this chapter assumes that taxes are a fixed amount, most countries levy some taxes that rise automatically with national income. (Examples in the United States include the income tax and the payroll tax.) Let’s represent the tax system by writing tax revenue as T = T− + tY, where T− and t are parameters of the tax code. The parameter t is the marginal tax rate: if income rises by $1, taxes rise by t × $1. 1.How does this tax system change the way consumption responds to changes in GDP? 2. Im the Keynesian cross, how does this tax system alter the government purchases multiplier? 3. In the IS–LM model, how does this tax system alter the slope of the IS curve? (solve all three tasks)
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.
Determine how each of the following monetary or fiscal policy would shift the aggregate demand curve. Illustrate and explain the following effect. a. Assuming the economy is currently producing above the full employment output, the government decided to increase the personal income tax as a form of contractionary fiscal policy. Illustrate and explain the effect of the policy using AD-AS curve. b. With the recession due to COVID-19, the central bank has decided to lower down discount rates and reserve requirements of the commercial bank. Illustrate and explain the effect of the policy using AD-AS curve.
The graph below depicts an economy where a decline in aggregate demand has caused a recession. Assume the government decides to conduct fiscal policy by changing taxes to reduce the burden of this recession. Fiscal Policy Instructions: Enter your answer as a whole number. If you are entering a negatlve number Include a minus sign. a. How much does aggregate demand need to change to restore the economy to its long-run equilibrilum? $, billion b. If the MPC is 0.6 , how much do taxes need to change to shift aggregate demand by the amount you found in part a? $, billion Suppose Instead that the MPC is 0.8 . c. How much does aggregate demand and taxes need to change to restore the economy to Its long-run equilibrlum? Aggregate demand needs to change by $ billion and taxes need to change by $ billion.
You are hired by the Council of Economic Advisors (CEA) as an economic consultant.The chairperson of the CEA tells you that she believes the current unemployment rate istoo high. The unemployment rate can be reduced if aggregate output increases. She wantsto know what policy to pursue to increase aggregate output by 300 billion TL. The bestestimate she has for the MPC is 0.8. Which of the following policies should yourecommend?a) Increase government purchases by 75 billion TL.b) Reduce taxes by 75 billion TL.c) Reduce taxes by 75 billion TL and to increase government purchases by 75 billion TL.d) Reduce the budget deficit by 300 billion TL
ax policy is one used not only for economic purposes but also for political purposes. It is the opinion of some economists and politicians that the rich should pay more of their income in taxes, and that the resulting fairness from this rise in taxes will lead to more economic growth and a rise in employment. Using the simple expenditure model (Y and Ep, not IS-LM) answer these two questions: One, would a lump-sum tax increase on many high-income households cause GDP to rise in the short run as predicted by the politicians? Why or why not? And two, are there macroeconomic conditions in the simple model under which such a tax increase would be fully warranted? Draw the graphs and explain the outcomes for both cases.
Assume that an economy is experiencing simultaneous equilibrium in both the product market and money market. Furthermore, assume the MPC is currently around a normal level of 0.65 and the sensitivity of real money demand to also around a normal level. Based on this information, answer the following questions: a) Using the AD-AS model and IS-LM model illustrate the impact of an expansionary fiscal policy. Label the initial points in both diagrams as A and the new points following the policy change as B.
Assume that an economy is experiencing simultaneous equilibrium in both the product market and money market. Furthermore, assume the MPC is currently around a normal level of 0.65 and the sensitivity of real money demand to also around a normal level. If the MPC rises to 0.8 and also the sensitivity of real money demand to changes in the income rises well, use the IS-LM model to illustrate the impact of an expansionary fiscal policy. Label the initial point prioer to the fiscal policy as A and the new point following the expansionary policy as B.
please explain this question in words. Assume that fiscal policy can be accomplished by changing only one of G and T. In the IS-LM framework, suppose the effect on the general equilibrium output is the same between expansionary fiscal policy and expansionary monetary policy. Which one would you expect to have a greater impact on the equilibrium consumption?
An economy is in long-run macroeconomic equilibrium when each of the following aggregate demand shocks occurs. What kind of gap - inflationary or recessionary - will the economy face after the shock, and what type of fiscal policies would help move the economy back to potential output? How would your recommended fiscal policy shift the aggregate demandcurve? (Note: you do not need to draw anything).(a) A stock market boom increases the value of stocks held by households.(b) Firms come to believe that a recession in the near future is likely.(c) Anticipating the possibility of war, the government increases its purchases of military equipment.(d) The quantity of money in the economy declines and interest rates increase.
The graph below depicts an economy where an increase in aggregate demand has caused inflation. Assume the government decides to conduct fiscal policy by decreasing government purchases to restore full-employment GDP. Instructions: Enter your answer as a whole number.
