- 3)Show and explain the effects of an increase in aggregate demand in the long-run and short-run by using AD–AScurves.2)Show and explain by using a graph, what will happen to the price level and real GDP if the quantity of moneyincreases and the increase is not anticipated; that is, the price level is not expected to change.1)By using aggregate demand (AD) and aggregate supply (AS) curves, show and explain the effects of ananticipated increase in money supply on macroeconomic equilibrium according to Rational ExpectationsHypothesis.Assume that investment, government expenditures, taxes are autonomous.C = 2000 + 0.65* (Y-T)I = 900 – 50iG = 400T = 1500M = 1000P = 2L = 0.50Y-25ia.What is the value of the sensitivity money demand to the level of income?b.What is the value of the nominal supply?c.What expression represents the IS curve?d.What is the equilibrium interest rate, i*?e.What is the equilibrium income, Y*?Which school of economic thoughts suggests that the speed of adjustment for self-correction to potential GDP would be very quick?O. monetarismO.

- i neeed it in word form.. not handwrittten Explain, with the aid of three separate IS-LM-FE diagrams, how a decrease in government purchases will affect real output, real interest rate and the general price level in three steps:(i) before the general price level adjusts;(ii) when the general price level is adjusting;(iii) after the price adjustment process is completed.Is the general price level increasing or decreasing during the price adjustment process? Explain the intuition of your answer with reference to the AD-AS framework.Stagflation is the combination of--------. Select one: a. a recessionary gap and a falling price level b. no recessionary or expansionary gap, but a rising price level c. an expansionary gap and a falling price level d. a recessionary gap and a rising price levelConsider a closed economy, where wages are sticky in the short run. The consumption function isC = c0 + c1(Y − T ), where the marginal propensity to consume c1 is equal to 0.75. Initially the economy is in equilibrium at Y = Y* and P = P e, where P e is the price level that was expected when agents agreed their fixed nominal wage contracts. The short-run aggregate supply curve (SRAS) is horizontal. Suddenly the government increases government spending G by $500. 1. By how much will output Y change (compared to its initial level before the change in G) in the long run, after wage contracts are renegotiated? 2. By how much will consumption C change (compared to its initial level before the change in G) in the long run, after wage contracts are renegotiated? 3. By how much will investment I change (compared to its initial level before the change in G) in the long run, after wage contracts are renegotiated?

Make sure to label (i) the axes, (ii) the curves and (iii) the initial equilibrium levels.Suppose that in Macroland the consumption and the investment have a negative relationship withthe real interest rate and positive relationship with Y. The Central Bank of the country targets acertain nominal interest rate and lets the money supply adjust in order to reach that interest rate.a. Draw a graph of the IS-LM model in this situation.b. Suppose that the Central Bank announces an increase of the interest rate in the future.Represent graphically the initial position of IS-LM curves. Then, show the IS-LM curves of thefuture, after the announced increase in the interest rate is implemented. (Assume that the ISis constant.).c. Suppose that agents today take into consideration the resulting income of the future whendeciding the amount of consumption and investment. Show what happens to the IS-LMcurves today after the announcement of the CB (tip: the CB is NOT increasing the nominalinterest rate today).d.

- Asap plz Assuming the economy has a strong-form market and that the current economy has reached its long-term equilibrium with optimal inflation rate π = 3 (%) and the aggregate output y = 10 (£bil). The economy has the following AD-AS curves: I. AD Curve: π = 10-0.7y II. AS Curve: π = 1+0.2y III. LRAS Curve: y = 10 Now, the central bank intends to use monetary policy to boost economic growth and suggest the government to increase £1bil in government expense. You are a researcher and now reviewing effect increased expense. a. What is the short-term equilibrium of π and y? b. What is the long-term equilibrium of π and y? c. What is the new AS curve? Do you think central bank’s suggestion on monetary policy effective?(52). Listen Keynes believed that the money supply played a minor role, if any, in causing changes in the business cycles. O. True O. FalseAssume the supply of loans decreases by 25%, even though the economy isinitially in both short-run and long-run macroeconomic equilibrium.
