A Keynesian economy is described by the following equations. Consumption                       Cd = 250 + 0.5(Y - T) - 250r Investment                           Id = 250 - 250r Government purchases       G = 300 Government taxes               T = 300 Real money demand            L = 0.5Y - 500r + πe Money supply                        M = 3000 Full-employment output   Y = 1250 Expected inflation             πe = 0 (HINT a: The expected rate of inflation is assumed to equal zero so that money demand depends directly on the real interest rate, which equals the nominal interest rate. Domestic Savings,  Sd =Y - C - G. In equilibrium set domestic savings equal to domestic investment, so Sd = Id) Calculate the values of the real interest rate (r), consumption (Cd), and investment (Id) for the economy in general equilibrium.

Consider the ASAD model of a closed economy with zero ongoing inflation and workers misperceptions. Firms are perfectly competitive, produce output with diminishing marginal returns to labour and have perfect foresight over the price level. Workers, instead, expect zero inflation in each period. At time zero, the economy is in the potential equilibrium. There is a negative shock on aggregate demand – for example, a permanent fall in desired autonomous consumption at time t = 1. What are the effects of the shock on the equilibrium real wage in the short and in the medium run?

When in macroeconomics an economy ‘overheats’ it is observed that aggregate demand exceeds national income at the full employment output level. Within a ‘Keynesian cross’ framework this overheating is described as which of the following: (a)  A Goldilocks effect; (b)  A hyperinflation; (c)  A recessionary gap; (d)  An inflationary gap Please illustrate the correct answer via a diagram.

Which of the following would cause the dynamic DAD curve to shift in (back)? A) a decrease in consumer confidence. B) a decrease in the inflation rate. C) an increase in consumer wealth. D) an increase in the short-run aggregate supply (SRAS) curve.

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.

(a) Using a basic Keynesian income determination model, describe the effects of the following changes, assuming that money demand is infinitely elastic: (i) an increase in government expenditure (ii) an increase in the marginal propensity to save (iii) a decrease in export demand (iv) an increase in the marginal propensity to import (v) a cut in the official rate of interest by the Monetary Policy Committee of the Bank of England Illustrate your answers with diagrams.

(a) Suppose that, in a liquidity trap, bank reserves are less liquid than government debt. If the central bank conducts an open market sale of government debt, what will be the effect on the price level? Use a diagram, explain your results. (b) Suppose that there is a decrease in the price of housing, which the central bank judges is a temporary asset price decrease. In the New Keynesian model, determine the central bank's optimal response to this asset price increase, using diagrams. (c) Suppose initially that inflation is at the central bank's target and the output gap is zero. Then, government spending goes up. Determine, with the aid of diagrams, how the degree of price stickiness affects the central bank's optimal response and explain your results.

Egypt authorities faced significant health and economic policy challenges during the COVID19 Pandemic, shutting down certain industries to protect public health. This shutdown resulted in almost 1 million jobs lost in April and May 2020, and a dramatic fall in consumers’ and firms’ confidence to spend and invest. Describe the effect that a fall in confidence had upon output in the Egypt economy using a Keynesian model of the macroeconomy. Ensure that your analysis includes the following:(i) the components of expenditure that are affected and why;(ii) the adjustment process associated with moving from an initial equilibrium (before the onset of the pandemic) to a new equilibrium (after the significant job losses), i.e. the mechanism that leads to a change in output (including a relevant diagram);(iii) an explanation of what the multiplier is and its role in explaining the fall in output; and(iv) a discussion of the policy actions that can restore aggregate demand to its initial level.
