Consider an AD-AS model with AD curve Y - Y* = −αy(n − ñ*) + € and AS curve π = π² + ¢ß(Y – Y*) + €s with parameter values a = 2, y = 1, p = 1 and ß = 2 and with inflation target * = : 0.01 and potential output normalised to Y* : = 1. e T Starting from a long-run equilibrium with ² = *, suppose there is a temporary supply shock €s = 0.05. Which of the following is FALSE? In the short run, inflation is 1% above target In the short run, output is 2% below potential In the short run, the real interest rate rises O In the short run, the real interest rate falls
The COVID-19 pandemic continues to present new challenges to the Australian economy. The Treasury has announced that they continue to support the economy by adding $41 billion in direct economic support, bringing total support since the beginning of the pandemic to $291 billion as of May 2021. Using a AD-AS graph, illustrate how this support would impact on economic growth and inflation in the short and long term
The IS-LM model for a closed economy is given below, where Y is the output, C is the consumption, I is the investment, T is the income tax, Md is the money demand, P is the price level, r is the real interest rate, n is expected inflation rate and G is the government expenditure.

Consider the classical AS-AD model with misperceptions. Assume that the economy is initially at its general equilibrium. Now, suppose the central bank considers an increase in the nominal money supply that is not anticipated by households or firms. a. How does the misperception theory work? b. Which of the three markets is first affected (labor, goods, or asset market)? Explain and show graphically how this market is affected by an unanticipated increase in the nominal money supply. c. Use the classical version of the AS-AD model with misperceptions to explain and to show graphically how an unanticipated increase in the nominal money supply affects the short-run equilibrium. d. Use the classical version of the AS-AD model with misperceptions to explain and to show graphically how an unanticipated increase in the nominal money supply affects the long-run (general) equilibrium.
new keynesian models assume that the business cycle fluctuations are driven by the aggregate demand components true or false
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?
(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.
Assume an economy that starts with Y = Y₂. Illustrate graphically and explain the impact of a fall in energy prices in the IS-LM-PC model with anchored expectations. Illustrate graphically, explain, and discuss the impact of the fall in energy prices depending on whether the central bank, firms, or workers have the power to adjust the economy to keep inflation at its target rate after the fall in energy prices. ་པཕབ་པ་
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.
Consider the following 3-equation model: Y 108-2rCB +2(G-T) (1) rCB =4+1.5(\pi-\pi)+0.5(Y-Y) (2) \pi \pie+0.5(YY) (3) wherey isoutput, \pi isinflation, \pi e =\pi = 2, andY* = 100. Expected future inflation is \pi e, and Y-Y⚫ is the output gap. The variable rCB is the interest rate set by the central bank. We may interpret \pi as the central bank's inflation target. Government ex- penditure, G, and net taxes, T, are given and set by the government. (a) Which equation is the IS curve, and which is the New Keynesian Phillips curve? Provide a brief economic explanation for the relationship between \pi and \pi e in Equation (3). (b) Find inflation, output and interest rates when G = T = 5. (c) Now suppose G = 8.5 and T = 5. How are inflation, output and interest rates affected? Is the impact of the fiscal expansion on output magnified or reduced by monetary policy? Explain.
Consider the short-term model characterized by the following AS and AD curves: Ý, = à – bm(x, – ñ) (AD] and A; = x; + vỶ, + õ, (AS). The economy is in steady state at time t = -1 (that is, a-1 = ñ, ō-1 = 0, and ā = 0). It is hit by a one-time inflation shock öy = .025 at time i = 0. For now, expectations are adaptive: 7 = ,-1. You'll use the answer to this question in several follow-up questions. To keep track of your results, you should use a spreadsheet application. If you don't already have one, you can use this hyperlinked template e (it's a Google Sheet). Calculate zo assuming b = 0.5, m = 2, ñ = 0.03, and ū = 1. Enter your answer as a percentage and round to the nearest hundredth.
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…
