- Explain it correctly not copy paste Q)In the Real Business Cycle model, what is the effective investment and the equilibrium investment?TRUE/FALSE. Brietly explain your answer. a) The real business cycle model is very helptul because we can always identity the sources of total factor productivity shocks. b) An increase in financial market frictions can cause the natural rate of interest to increaseIs fiscal policy, say an increase in government expenditures (G), effective according to the Real Business Cycle (RBC) theory? If it is, should it be used? Explain by using production function, labor market, goods market and asset market equilibrium tools.
- Consider a closed economy. A. Provide a graphical analysis of the effect of a temporary but persistent increase in total factor productivity (TFP) on current employment, current output, current investment, current real wages, current prices and current real interest rates in terms of the Real Business Cycle Model. Explain why each of the curves in your analysis shifts in response to the shock. B. Do we observe changes in total factor productivity? How are they calculated? C. Why do we assume that changes to TFP are persistent?Economics Suppose that the effects of COVID-19 on the economy can be thought of as a permanent negative productivity shock, i.e., a permanent decrease of the production owing to lower total factor productivity. What does the model predict will happen to the following variables: (1) real interest rate, (2) real output), (3) real consumption, (4) real investment, (5) labor input? For each variable explain why COVID-19 would have the predicted effect.Consider an Economy in its medium run equilibrium. Now suppose that the government passes a stricter law against the exercise of market power leading to decline in mark-up over wages. Explain using IS-LM and AD-AS curves how it will affect price level, interest rate and output in the short run and in the medium run.
- Calculations with the IS curve: Suppose the parameters of the IS curve are a = 0,b = 3/4, r = 2% and the real interest rate is initially R = 2%. Explain whathappens to short-run output in each of the following scenarios (consider eachseparately):(a) Te real interest rate rises from 2% to 4%.(b) Te real interest rate falls from 2% to 1%.(c) ac increases by 1 percentage point.(d) ag decreases by 2 percentage points.(e) aim decreases by 2 percentage points.Suppose the economy is initially in its long-run equilibrium. Due to the biased (overestimated) expectation of return, the entrepreneurs overwhelmingly become much more aggressive in investment holding other things equal. a. Use the IS-LM model and AD-AS model to graphically illustrate the impact of the biased expectation in the short run and in the long run. What are the changes in the equilibrium real interest rate, output, and prices? b. If the central bank wants to offset the impact of the biased expectation, what is the appropriate measure? Draw a graph as in part a. for illustration. What are the changes in the equilibrium real interest rate, output, and prices in this case?Consider a closed economy. Provide a graphical analysis of the effect of a temporary but persistent increase in total factor productivity (TFP) on current employment, current output, current investment, current real wages, current prices and current real interest rates in terms of the Real Business Cycle Model. Explain why each of the curves in your analysis shifts in response to the shock. Do we observe changes in total factor productivity? How are they calculated? Why do we assume that changes to TFP are persistent? Compare graphically the behaviour of the current Average Productivity of Labour and Employment in the Real Business Cycles Model and the Coordination Failure Model following a temporary increase in current total factor productivity. Are the two different and how do these results compare to the data?
- Why is Okun's law a useful rule of thumb to keep in mind when analyzing our short-run model?Urgentttt!!! Use the IS-LM model to answer this question. Suppose there is a simultaneous increase in government spending and reduction in the money supply. Explain what effect this particular policy mix will have on output and the interest rate. Based on your analysis, do we know with certainty what effect this policy mix will have on investment? Explain.Assume that the United States economy is currently in a recession in a short-run equilibrium. When interest rates fall, what is the impact on each of the following? (i) Investment (ii) Economic growth rate. Explain
