Question 3 3.1 Suppose the economy of Panicia is initially at a long-run equilibrium. The Central Bank then increases the money supply growth rate. Assuming that any resulting inflation is expected, describe any likely changes in output and inflation that are caused by the increase in the money supply growth rate. Explain your conclusions using the aggregate demand-aggregate supply (AD-AS) diagram. 3.2 The Central Bank of Lala-land decides to increase the target inflation rate from 2 to 3 percent. Using the dynamic AD-AS model, show the effect of the change in the inflation rate by drawing a graph. When you draw your graph, assume that the economy is initially in the long run equilibrium. Please provide a brief explanation of your graph. (Hint: Use the Reserve Bank's policy reaction function (Taylor rule) and the AD-AS model)

Explain.c) Show with calculus how the velocity of money reacts to a change in output and a changein the nominal interest rate.d) Find the income and the nominal interest rate elasticities of money demand.
1) Inflation in Theoretica is currently below the target range of its central bank. What does this tell you regarding Theoretica’s likely output gap? Illustrate it using an AS-AD diagram, and briefly explain your diagram 2) Your mother states that lowering interest rates in the recessionary COVID-19 period is good policy because it will guarantee consumers will spend more as it is cheaper to borrow money. Do you agree or disagree with her statement? Provide two reasonings to justify your answer. 3) Is either helicopter money or quantitative easing preferred in times of severe recessions in order to boost economic activity? Explain your reasoning.
Suppose that an economy has a constant nominal money supply, a constant level of real output Y = 1500, and a constant real interest rate r = 0.05, and it’s expected rate of inflation is 2%, i.e, πe = .02. Suppose that the income elasticity of money demand is ηY = 0.5 and the interest elasticity of demand ηi = –0.2. (a) Suppose that Y decreases to 1425, r remains constant at 0.05 and there is no change in the expected rate of inflation. What is the percentage change in the equilibrium price level? (b) Suppose that r increases to 0.06 and Y remains at 1500. Assuming that expected inflation remains at πe = .02, what is the percentage change in the equilibrium price level? (c) Suppose that r increases to 0.06. Assuming that πe = .02, what would real output have to be for the equilibrium price level to remain at its initial value?
Suppose you observe the time series of output y and real money supply M/ P reported in the Figure below. Nominal money supply M is under full control of the Central Bank. Output y Real Money Supply M³/P Time t Time t 1 3 4 1 2 3 4 6. Interpret these time series using the ASAD Redux model with workers misperceptions (Lecture Notes, Chapter 1). Assume that the time paths are caused by a single permanent shock hitting the economy at time t= 1, and interpret time t = 6 as the medium run. Your general task is to guess what type of shock can be responsible for the observed time series. Answer each of the following questions, providing clear motivation for your statements: (a) Can the shock be a permanent change, positive or negative, in public expenditures G? Motivate your answer.

The following graph shows a decrease in short-run aggregate supply (AS) in a hypothetical economy where the currency is the dollar.

2. Suppose the monetary-policy rule has the wrong natural rate of interest, and the central bank follows this rule: ių = T; + pl+8,(T; – n}) +Oy (Y, – Y.), where pl does not equal p, the natural rate of interest in the goods demand equation. The rest of the dynamic AD-AS model is the same as in the chapter. Solve for the long- run equilibrium under this policy rule. Explain in words the intuition behind your solution.

Use relevant graphs to describe how a Central Bank’s action on the interest cashrate ripple through the economy and lead to the target policy goal. (Three connected diagramsshould be used: (1) money supply and demand (2) investment demand schedule (3) AS/ADdiagram. Interest rates is the variable that connects the first and second diagram).

16. Keynes (1936) argued that, from a policy perspective, everything that can be achieved by a nominal wage cut can be more effectively achieved through an appropriate monetary policy. (a) Does this statement hold in the deﬁcient-demand Keynesian model for a negative shock to (i) aggregate demand and (ii) aggregate labor productivity? (b) Does this statement hold in the new Keynesian model for a negative shock to (i) aggregate demand and (ii) aggregate labor productivity?
