In this exercise, we analyze how loose monetary policy can lead to high rates of inflation. Imagine that at t=1, policymakers observed that GDP was lower than what they expected. So, they assumed that output was below its potential due to a negative aggregate demand shock. Use the IS-MP + Phillips Curve model to predict what happens to short-run output (Ỹ₂) and inflation (™) in each of the following cases: Case A: Assume that there is a negative aggregate demand shock (ā < 0) but the Central Bank does not respond so the interest rate is r = r. Case B: Assume that there is a negative aggregate demand shock (ā < 0) and the Central Bank responds by lowering the interest rate: rt < F. Case C: Assume that policymakers misinterpreted the data and what actually happened is that GDP was low because potential output was low, while there was no aggregate demand shock. That is: there is no aggregate demand shock (ā = 0) but still the Central Bank responds by lowering the interest rate: rt < ñ.

Assume an imaginary country called Narnia. Firms in this country heavily rely on natural gas as a raw material to produce the final output. Assume a sudden fall in the price of natural gas. This shock is an event that directly affects firms' costs of production and thus the price that they charge. Describe the effects of this shock on the aggregate supply curve and on the Phillips curve of the economy of Narnia. Use a diagrammatic analysis to provide your answer.
In the decade through 2020, inflation was consistently low. If people adjusted their inflation expectations to their actual inflation experience, this would shift the short-run Phillips curve down. shift the short-run Phillips curve up. shift the long-run Phillips curve to the left. Shift the long-run Phillips curve to the right.
Which of these graphs shows the effect on the Phillips curve in Ethiopia of an appreciation of the country's currency, the Ethiopian birr? Unexpected inflation Rising costs Unexpected inflation Real interest rate Real interest rate Output gap Falling costs Output gap Decreased Interest rates Output gap Increased spending
An implication of the Rational Expectation Theory is that A) rational expectations of inflation are reformulated sooner than adaptive expectations of inflation. B) changes in how the inflation variable moves over time will not affect how expectations are formed. C) people can always accurately assess the actual rate of inflation. D) people always underestimate the future rate of inflation. E) people always overestimate the future rate of inflation.
A well-known economic model called the Phillips curve (discussed in the Keynesian Perspective chapter) describes the short run trade off typically observed between inflation and unemployment. Based on the discussion of expansionary and contraction monetary policy, explain why one of these variables usually falls when the other rises.
Draw a Phillips curve graph here that shows a natural rate of unemployment of 4% and a current inflation rate of 2%. Make sure your lines and axes are labeled and your graph is complete! Use your knowledge of The Phillips Curve to answer the following questions. The threat of future inflation: makes people reluctant to loan money for long periods. makes people eager to loan money for long periods. has no effect on loaning money. increases the value of money paid back in the future. makes people reluctant to borrow money for long periods. According to the short-run Phillips Curve, there is a trade-off between: interest rates and inflation. the growth of the money supply and interest rates. unemployment and economic growth. inflation and unemployment. economic growth and interest rates. Which of the following is true of the long-run Phillips curve? it shows there is a trade-off between unemployment and inflation. it is positively sloped when the inflation rate exceeds…
Question 3: The Phillips Curve and Inflation Expectations Consider the following two modifications to the Phillips Curve equation we studied in class The Federal Reserve has been successful in achieving stable inflation around its target rate of 2% per year. Therefore, we may expect inflation expectations to be "anchored" in the sense that private sector agents expect inflation to eventually return to target over the long-run after any economic shocks. Suppose that inflation expectations are not adaptive, but are anchored to the inflation target as follows: π = (1-р)π + pπt-1 This equation says that firms forecast inflation as a weighted average of the inflation target and yesterday's inflation Tt-1. Note that adaptive expectations are a special case of this where the weight on yesterday's inflation p = 1. i. ii. Many economists have documented that the empirical Phillips Curve is almost flat. Therefore, suppose that the Phillips Curve does not depend on the current state of the…
Let's say that at some time in the past the central bank of a nation raised real interest rates to get inflation under control. Inflation has stayed low now for a couple of years. As people in the economy build this now-lower inflation into their expectations, the economy will move further away from the LR value of output we'll move to the right along the same Phillips Curve the Fed will shift the MP curve further upward the Phillips curve will shift rightward
According to Modern Phillips Curve Theory, an increase in the sensitivity of inflation to changes in real GDP results in: (a) lower Durbin-Watson statistics across econometric estimations; (b) a movement to the left of the long-run aggregate supply curve; (c) decreased employment volatility over several economic cycles; (d) more inflation
If we use the simple monetary policy rule R: = F + m(Tt – ñ), and the IS curve equation Yt = ā – b(R¢ – F), and inflation evolving according to the Phillips T +vÝt,with inflation expectations formed using T Curve equation: Tt %3D Tt-1. We observe: D = 0.5 marginal product of capital is 5%, target rate of inflation is 3%, the current rate of inflation is 6%, m = 0.6, b = 0.7: Solve for the rate of inflation at time t+1. Enter you answer in percent rounded to one decimal place, but do not use any % symbol. This means something like 4.3% would just be entered "4.3". Type your answer.
How does the short-run Phillips curve reflect an increase in the price of oil such as occurred in the early 1970s? as a leftward shift in the short-run Phillips curve as a rightward shift in the short-run Phillips curve as a downward movement along the short-run Phillips curve as an upward movement along the short-run Phillips curve
