An economy is described by the following equations: Desired consumption cd=130 +0.5(Y-T)-500r Id=100-500r Desired investment Government purchases G = 100 Taxes T = 100 Real money demand Money supply L = 0.5Y - 1000r M = 1320 Full-employment output Y = 500 Assume that expected inflation is zero so that money demand depends directly on the real interest rate. Also assume the SRAS is horizontal at the current price level. a. Write the equations for the IS and LM curves. (These equations express the relationship between r and Y when the goods' and asset mar- kets are in equilibrium.) b. Calculate the full-employment values of output, the real interest rate, the price level, consumption, and investment.

Given information: Aggregate Demand function/equation: P = 1400 - 0.4Yr Aggregate Supply function/question: P = 200 + 0.2Yr Full employment real GDP = Yf = $10,000 P = CPI, Yr = Real GDP
Consider starting from full-employment equilibrium in our Aggregate Demand and Supply model (with flexible wages and worker misperception of price level changes in the short run), at Po, QN on the output market graph below. Then we get an increase in Aggregate Demand from Agg Do to Agg D1. Group of answer choices a) In the long run, P will increase further above P1 as workers finally get a full cost of living raise. b) at P1, Q1, we are in a recessionary gap. c) In the long run, P and Q will return to their original levels when workers perceive the decrease in P. d) In the long run Q will increase further above Q1 as employment increases (due to workers getting wage increases). e) None of the other options.
Based on research conducted by the Department of Economic Analysis, the government and policy advisors of an economy believe that the full employment GDP is $7500 billion, and Pe, the overall expected price level is 118. In addition, the researchers estimate that the short run aggregate supply equation is Y = Ypot + 80 (P- Pe), where Ypot is the potential level of output. In 2016, the population was 400 million, and the structure of the economy was described by the following equations for household consumption behavior and taxes received: C = 100+ 0.8DI, and T = 0.25Y where all monetary values are in billions of dollars. Government spending was fixed at $1700 billion, and firm's investment behavior was fixed at $800 billion. Trading is allowed in this economy and in 2016, trading occurred such that the trade account was balanced. That is, net exports (X-IM) was equal to zero. Question 17 of 20) Now consider that in in the following year (2017), the government decided to implement a…
Consider 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. Assume constant marginal productivity of labor. What will be the result of an increasing government consumption expenditure in this module, if not other paramiters are changed? a. Lower investment. b. Higher employment. c. Higher inflation. d. Lower employement.

Desired consumption is Cd = 100 + 0.8Y - 500r - 0.5G, and desired investment is I d = 100 - 500r. Real money demand is Md/P = Y - 2000i. Other variables are: expected inflation = 0.05, G = 200, y
C = 100 + 0.5 · (Y – T) I = 500 – 1000 - r where Y is real output and r is the real interest rate. Government purchases and taxes are Ğ = 500, T = 100. The LM (money market equilibrium) curve is MY P 5i where P is the price level and i is the nominal interest rate. The Central Bank (CB) is initially supplying M = 8000 units of money, and expected inflation is a = 0. Assume that the long-run equilibrium level of output is Y = 2000. Short-run equilibrium output is initially at the same level (Y = 2000). Suddenly, news of a new world-beating super-vaccine raises expected inflation to = 0.05. 1. Suppose the government (not the CB) wants to stabilise the shock in the short-run. Explain whether it should increase the government deficit (AĞ > AT) or reduce it (AĞ < AT), and how it works. 2. Now suppose the government doesn't do anything, and the CB wants to stabilise the shock in the short-run. Explain whether it should decrease or increase money supply M if it wants to bring output Y back to…
Consider the ASAD model of a closed economy with zero ongoing inflation in the medium run. The aggregate demand curve is determined by the IS-LM model. The aggregate supply curve is derived from the imperfect competition model of the labour market (the WS-PS model where firms have perfect foresight, monopoly power, and use a linear technology with constant returns to labour; workers expect zero inflation in every period, and their wage requests are an increasing function of wage-push factors like unions' bargaining power). The economy is initially in the potential equilibrium. Assume a permanent increase in the bargaining power of unions. Fiscal and monetary authorities perfectly forecast this shock and decide to neutralize immediately its consequences for the price level by enacting a “policy of price stability” that successfully eliminates all fluctuations in the general price level in every period. Therefore, the economy is subject to two simultaneous shocks – the increase in…
If the economy is in a long-run equilibrium when the Federal Reserve decides that its inflation target is too low and chooses to raise it, ________. A) it would likely conduct a tightening of monetary policy by raising the real interest rate for any given inflation rate B) it would likely conduct an easing of monetary policy by lowering the real interest rate for any given inflation rate C) it would likely conduct an easing of monetary policy where the real interest rate would increase due to the ensuing decrease in aggregate demand D) it would likely conduct a tightening of monetary policy where the real interest rate would increase due to the ensuing increase in aggregate demand E) none of the above
What is inflationary gap? Select one: When aggregate expenditures are greater than the full employment level causing a demand pull-inflation When aggregate expenditures are greater than full employment level causing cost push inflation None of the options are correct It is the gap between a developed nation GDP and an under-developed/ developing nation GDP When aggregate expenditures are inadequate to bring about a full employment level
