Part 1: Long-Run Self Adjustment- Draw a correctly labeled graph of aggregate demand, aggregate supply, and long-run aggregate supply. Start each graph at full employment. Show what happens in both the short-run and the long-run if the economy is given time to self-adjust. 1. Consumer spending increases as consumers confidence increases 2. Congress passes a bill dramatically reducing government spending

1) According to the Phillips Curve, as unemployment falls what happens to inflation? Why? 2) According to the Phillips Curve, as unemployment rises what happents to inflaiton? Why? 3) According to the Aggregate Supply/ Aggrgeate Demand model, if AD increases what happebs to Price Level GDP and Unemployment 4) Accroding to the AS/AD model, if AD decreases what happens to PL, GDP and unemployment? 5) According to the AS/AD model if AS decreases what happens to PL GDP and unemployment? 6) Based on your answer to #5 how would you show the decrease in AS on the Philips Curve?
A. What assumptions did Thomas Sargent make when he claimed that inflation is always and everywhere a fiscal phenomenon?" B. Why is it appropriate in the book's short-term model for the author to use the Phillips Curve as an Aggregate Supply curve? Does it capture the working of the labor market as well as an AS curve based, say, on sticky wages? C. Provide an example of the book's short-run model being based on "microfoundations."
Consider the expectations adjusted Phillips’s curve and assume that expected inflation is given by πet = πt-1. Suppose that unemployment is initially equal to the natural rate and that π=10%. The central bank decides that inflation is too high and that, starting in year t, it will maintain the unemployment rate 1% point above the natural rate until the inflation rate has decreased to 2%. (a) What is the sacrifice ratio in this economy [Hint: the sacrifice ratio is the percentage of a year’s excess unemployment needed to reduce inflation by 1%. For a Philips curve given as πet − πt −1 = −α (ut − un ), the sacrifice ratio is 1/α]? (b) Compute the rate of inflation for year t, t+1, t+2, t+3, …, t+8. (c) For how many years must the central bank keep the unemployment rate above the natural rate of unemployment? Is the implied sacrifice ratio consistent with your answer to (a)?
An economy has the following equation for the Phillips Curve: π = Eπ − 0.5(u − 6)People form expectations of inflation by taking a weighted average of the previous two years of inflation: Okun’s law for this economy is: Eπ = 0.7π−1 + 0.3π−2 (Y −Y−1)/(Y-1)=3.0−2.0(u−u−1) Th economy begins at its natural rate of unemployment with a stable inflation rate of 5 percent. 1. What is the natural rate of unemployment for this economy? 2. Graph the short-run tradeoff between inflation and unemployment that this economy faces. Label the point where the economy begins as A. 3. A fall in aggregate demand leads to a recession, causing the unemployment rate to rise 4 percentage points above its natural rate. On your graph, label the point the economy experiences that year as point B.
1. In the RBC (Real Business Cycle) model, if businesses react to a pessimistic outlook and decrease spending, the model predicts a. the aggregate demand curve shift left. b. equilibrium inflation rates fall. c. no change in long run growth rates. d. a&b only e. all of the above 2. In the RBC (Real Business Cycle) model, if you observe unemployment levels rising, what is the likely cause? a. A negative real shock b. A negative aggregate demand shock c. A negative SRAS shock d. A&B only e. None of the above 3. Irrigation technology that changes how farmers utilize rainfall a. will have no effect on economic growth if rain fall levels do not also increase. b. represents a positive aggregate demand (AD) shock. c. may lead to higher levels of productivity growth and lower levels of unemployment. d. represents a negative real shock and will increase unemployment. e. None of the above.
MA4. 13. If the equation for a country's Phillips curve is π = 0.05 – 0.8(u – 0.05), where π is the rate of inflation and u is the unemployment rate, what is the short-run inflation rate when unemployment is 3 percent (0.03)?

B) policy by discretion. C) time inconsistency of policy. D) monetary policy. 10. According to the sticky-price model, output will be above the natural level if: A) firms expect a high price level and the demand for goods is high. B) the proportion of firms with flexible prices equals the proportion of firms with sticky prices. C) the price level is above the…
Assume that inflation falls significantly below expectations. Diagramboth the short-run and long-run effects on employment using a PhillipsCurve diagram. What changes in this model to allow the return to long-runequilibrium?
a. Suppose the Australian government announces that it will bring the federal budget deficit to zero, over the next ten (post-pandemic) years, with no change in tax rates. Describe the effects of such a policy according to the three business cycle models, assuming that the policy is fully credible. b. How do new Keynesian ideas about price setting and inflation expectations affect the short-run aggregate supply curve? Explain.
