Consider the AS-AD and three-equations models of a closed economy. Write down the expressions for the AS and AD curves and interpret the expressions: what is the intuition behind the two curves? What must be true of the model parameters and variables in the long-run equilibrium, i.e. in the steady state? Analyse the effects of an oil supply shock that causes a temporary increase in inflation, using the three-equation model. Assume that the shock lasts for one-period and then assumes the value 2%. Describe the mechanisms that bring the economy back to long-run equilibrium. What happens to aggregate demand? Consider an economy that starts out in steady state when the central bank decides to make the inflation target more ambitious. Analyse the effects of a decrease in the inflation target from ? to . Explain the mechanisms behind the adjustment to the new steady state.

Coronavirus pandemic and resultant shutdown measures to contain it have plunged the economies around the world including Singapore into severe contraction. Assuming Singaporean economy was in long run equilibrium in the aggregate demand and supply (AD-AS) model before the pandemic (and consequent shutdown) started, answer the questions below: a) Assuming the contraction in the Singaporean economy is mainly driven by demand side factors, Show the short-run effects of this using the AD-AS model. Carefully explain in words (100 or less). Graph Explanation b) Now assume that the contraction in the Singaporean economy is mainly driven by supply side factors, Show the short-run effects of this using the AD-AS model. Carefully explain in words (100 or less). Graph Explanation [1] Make sure to label the variables represented on the X-axis and Y-axis of the graph clearly. Also mark the curves in the graphs clearly…

In the sticky-price model, describe the aggregate supply curve in the following special cases. How do these cases compare to the short-run aggregate supply curve we discussed in Chapter 10? All firms have sticky prices (s = 1). The desired price does not depend on aggregate output (a = 0).
Use a standard dynamic AS-AD model to explain how the macroeconomy adjusts following a favourable supply shock (vt < 0) for one period which reverts to zero for all subsequent periods. Assume that the economy starts from its long-run equilibrium. As a reminder, the DAD and DAS curves, respectively, are provided below: Y =Y - αθη 1+aly Tt = t_1+ ¢(Y - Y)+v where Y is output, πt is inflation, 0 and Oy capture the responsiveness of the central bank to inflation and output, a is the sensitivity of output to the real interest rate and is the sensitivity of inflation to the output gap. Y is the natural output level, and π* is the central bank's inflation target.

Q1. Consider the IS-LM model. Suppose the economy of Economica is initially at the general equilibrium. This year, Economica’s economy is hit by a negative oil price shock, i.e., oil prices in Economica increase dramatically. a. Explain and show graphically how an oil price shock affects the labor, goods, or the asset market. b. Explain and show graphically how an oil price shock affects the short-run equilibrium. c. Explain and show graphically how an oil price shock affects the general (long-run) equilibrium.
The classical model is appropriate for analysis of the economy in the long run, since evidence indicates that money is not neutral in the long run. long run, since real and nominal variables are essentially determined separately in the long run. short run, provided money is not neutral. short run, provided real and nominal variables are highly
