- Suppose that for years East Confetti's short-run Phillips Curve was such that each 1 percentage point increase in its unemployment rate was associated with a 4 percentage point decline in its inflation rate. Then, during several recent years, the short-run pattern changed such that its inflation rate rose by 3 percentage points for every 1 percentage point drop in its unemployment rate. Graphically, did East Confetti's Phillips Curve shift upward or did it shift downward? |(Click to select) VStep 1 Plot the graphs. The corresponding table includes a breakdown including Inflation Rate, Unemployment Rate, Price Level, and Real GDP. Using the data below, plot the graphs: Plot the short-run Phillips curve and the aggregate supply curve on separate graphs. Plot the long-run Phillips curve on a separate graph, when the natural unemployment rate is 6%. Inflation Rate Unemployment Rate Price Level Real GD 2% 7% 104 9.8 3% 6% 103 10.0 4% 5% 102 10.22. Analyze the effects of the following developments on both the short-run and the long-run Phillips curves. Use the graphs and explain in detail: a) a rise in the natural rate of unemployment b) a substantial increase in the price of energy
- 5. Consider the standard Phillips curve. Select all the correct statements: (a) A positive aggregate demand shock will lead to an upward shift in the Phillips curve. (b) Changes in short-run output will lead to movements along the Phillips curve. (c) A negative inflation shock will lead to movements along the Phillips curve. (d) A shock to the price of oil will lead to a shift in the Phillips curve. (e) The inflation rate will always be equal to zero when short-run output is equal to zero.2. What is the eqution and shape of the modem aggregate supply curve according to imperfect infomation model? Using the equation of Aggregate Supply (AS) derive the equation of Expectation augmented Phillips curve and explain causes of inflation in tems of it. How does expectation augmented Phillips curve explain Stagflation?1. The inflation-unemployment relationship The following graph shows the combinations of unemployment and inflation that existed in the United States from 1961 through 1969. Hint: Use the graph to answer the following questions. Select any blue point (circle symbol) on the graph to get its exact coordinates. INFLATION RATE (Percent) 5.0 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 a O 3.0 3.5 1969 1968 1967 1965 4.0 1964,982 1963 4.5 5.0 5.5 6.0 UNEMPLOYMENT RATE (Percent) 6.5 What happened to the inflation rate between 1962 and 1965? The inflation rate decreased by 2 percentage points. The inflation rate increased by 0.5 percentage points. The inflation rate increased from 4% to 5%. The inflation rate decreased from 1.9% to 1.5%. 1961 7.0 Scratch Point ? The points on the graph represent observations along the U.S. economy's Phillips curve during the 1960s.
- For each of the following scenarios, illustrate the effects of the development on both the short-run and long- run Phillips curves (SRPC and LRPC respectively). Plz show a colored graph so I can see if I moved them to the right positions For each of the following scenarios, illustrate the effects of the development on both the short-run and long-rum Phillips curves (SRPC and LRPC, respectively) There is a fall in the natural rate of unemployment. LRPC Unemployment Rate SRPC There is an advance in technology that makes production more efficient. There is a decrease in taxes. LRPC Unemployment Rate SAPC SRPC LRPC SAPC ° Movement along SRPC LRPC LRPC SRPC5. Consider the following changes in the sticky-wage model. a. Suppose labor contracts are fully indexed for inflation so that as inflation changes. That is, the nominal wage is to be adjusted to fully compensate for changes in the consumer price index. How does full indexation alter the AS curve in this model? b. Suppose that now indexation is only partial. That is, for every increase in the CPI, the nominal wage rises, but by a smaller percentage. How does partial indexation alter the AS curve in this model?Specific subject - Macroeconomic Analyse the case of a negative supply shock caused by an increase in oil prices and compare with the shock caused by the Covid pandemic. What would be the similarities and differences between the two shocks? What would be the effect of an expansionary economic policy (increase in aggregate demand)? Graph What measures or government intervention would be most appropriate to deal with both types of shocks? Graph Compare the adjustment in both cases with and without government intervention. Graph
- A generalization of the fisher effect that can be applied to other variables is the relationship between real price growth and nominal price growth if we know the inflation rate. We can express this relationship T, where g is the growth rate (real or nominal) and t is inflation rate. Use this as greal information for problems 10-12. gnomial - 10. Assume that data shows the nominal price of a new Nissan Maxima was $12,000 in 1992 and $15,000 in 2002, but you also found a reliable source that claimed real price growth for Maximas this claim about real price growth A) 16.5% B) 5% C) 10% D) 8.5% E) Not enough information to determine was closer to 8.5%. For experienced from 1992 to 2002? to be true, how much inflation was 11. Assume that the inflation rate is the level you found in 10. If the real price growth for a Mercedes- AMG was 10%, and the nominal price in 1992 was 2002? $42,000; what is the nominal price of the Mercedes in A) $50,000 B) $53,130 C) $56,750 D) $60,070 E) $77,000 12.…15. Suppose that the relationship between inflation rate (x) and unemployment rate (u) is described by the following equation: H, - n = (m + z) – au, where m = 0.05, z = 0.04, and a = 2. In this economy, the authorities keep unemployment rate at 4% forever. a. If the modified Phillips curve describes the relationship between a and u correctly, how should "x,*" be specified? Rewrite the equation using this specification. And assuming that 7-1= 1%, compute Af, T4+1, and x4+2. b. Derive the natural rate of unemployment.11. Changing the slope of the Phillips curve: Suppose the slope of the Phillips curve the parameter -increases. How would the results differ from the Inc Volcker disinflation example considered in the chapter? What kind of changes in the economy might influence the slope of the Phillips curve? on
