Answer the following questions regarding the Keynesian perspective.  From a Keynesian point of view, which is more likely to cause a recession: aggregate   demand or aggregate supply, and why? Why do sticky wages and prices increase the impact of an economic downturn on unemployment and recession? Explain what economists mean by “menu costs”.

Consider the original presentation of the Phillips Curve, with inflation on the vertical axis and unemployment on the horizontal axis. Which of the following could NOT shift this Phillips Curve upward? an increase in the price of inputs used in production expected higher prices in the future/higher inflation an increase in the average wages of workers an improvement in production technology

Consider an economy for which wage and price inflation are initially 3% under a zero output gap. Calculate price inflation by the end of the current period under a new output gap of 6%. (Hint: you need to use the Phillips curve equation)

If expected inflation rises, the long-run Phillips curve will Group of answer choices not be affected. become negatively sloped. shift to the right. shift to the left.

1. Aggregate demand, aggregate supply, and the Phillips curve In the year 2027, aggregate demand and aggregate supply in the imaginary country of Aso-Kuju are represented by the curves AD2027 and AS on the following graph. The price level is currently 102. The graph also shows two potential outcomes for 2028. The first possible aggregate demand curve is given by the curve labeled ADA curve, resulting in the outcome given by point A. The second possible aggregate demand curve is given by the curve labeled ADB, resulting in the outcome given by point B. PRICE LEVEL 108 107 106 105 104 103 102 101 100 0 AD 2027 2 4 B AS ADB ADA 8 10 6 OUTPUT (Trillions of dollars) 12 14 16 (?) Suppose the unemployment rate is 7% under one of these two outcomes and 5% under the other. Based on the previous graph, you would expect outcome B▼ to be associated with the lower unemployment rate (5%). If aggregate demand is high in 2028, and the economy is at outcome B, the inflation rate between 2027 and 2028…

In the year 2020, aggregate demand and aggregate supply in the fictional country of Drooble are represented by the curves AD2020 and AS on the following graph. The price level is 102. The graph also shows two possible outcomes for 2021. The first potential aggregate demand curve is given by the ADA curve, resulting in the outcome illustrated by point A. The second potential aggregate demand curve is given by the ADB curve, resulting in the outcome illustrated by point B. PRICE LEVEL 108 107 B 106 105 104 103 AD 2020 102 101 100 0 2 4 6 8 A 10 OUTPUT (Trillions of dollars) AS AD A ADB 12 14 16 ? Suppose the unemployment rate is 5% under one of these two outcomes and 2% under the other. Based on the previous graph, you would expect to be associated with the higher unemployment rate (5%). If aggregate demand is low in 2021, and the economy is at outcome A, the inflation rate between 2020 and 2021 is

Discuss what the long-run Phillips curve looks like in the neoclassical perspective, and why the trade-off between inflation and unemployment disappears.  From this perspective, what is the best government policy response to favorable economic conditions in the long run?

The Short-Run Phillips Curve given by T = E (x) – 0.4 (u – 10) + v Suppose that the economy has adaptive expectations and no inflation shocks. If inflation goes down by 3.3 percentage points a year from today, what is the unemployment rate one year from now? Round your answer to the nearest two decimal place. Write your answer in percentage terms so if your answer is 10%, write 10.

Consider the model of unemployment with job separation rate s = 0.05 and job finding rate f = 0.20. If the unemployment rate U = 10,000, L = 200,000, and E = 190,000 then what will the natural rate of unemployment be? Please show your calculation. If U were to fall to 5,000 because of an exogenous shock, how would the unemployment rate change in the short run? In the long run? If s were to fall to 0.03 because of an exogenous shock, how would the unemployment rate change in the short run? In the long run?

Lucas's critique, based on rational expectations, argues that it is not enough to use econometric models to evaluate policy. In this regard, explain the comparison of the new classical macroeconomic model, the new Keynesian model and the traditional model on the impact of rational expectations on the aggregate economy!
