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."

true or false Suppose that the central bank lost credibility in the sense that people no longer believe its inflation target (that is, inflation expectations are not `anchored’). In this case, both short-run output and long-run output do not increase in response to a permanently higher inflation target.
Hi, could you help me solve this problem? Consider an increase in global oil and gas prices from the point of the euro area (that does not produce much oil or gas itself). Think of this shock as a supply shock and use the AD-AS -model to explain how it is likely to affect output (or unemployment) and inflation. How does your result relate to the original Phillips curve? Your answer should include a graph and a short explanation in words.
Suppose the economy is in a long-run equilibrium.a. Draw the economy’s short-run and long-run Phillips curves.b. Suppose a wave of business pessimism reduces aggregate demand. Show the effect of this shock on your diagram from part (a). If the Fed undertakes expansionary monetary policy, can it return the economy to its original inflation rate and original unemployment rate?c. Now suppose the economy is back in long-run equilibrium, and then the price of imported oil rises. Show the effect of this shock with a new diagram like that in part (a). If the Fed undertakes expansionary monetary policy, can it return the economy to its original inflation rate and original unemployment rate? If the Fed undertakes contractionary monetary policy, can it return the economy to its original inflation rate and original unemployment rate? Explain why this situation differs from that in part (b)
An economy is currently in a recession. (a) Draw a single correctly labeled graph with both the short-run and long-run Phillips curves. Label the current short-run equilibrium as point X. (b) Is the expected inflation rate greater than, less than, or equal to the actual inflation rate? (c) Will borrowers on fixed-rate loans benefit from the situation that you identified in part (b)? Explain. (d) Assume the government budget is balanced. In the absence of any discretionary policy action, will the government budget move into surplus, deficit, or remain in balance? Explain. (e) On your graph in part (a), show how the economy will adjust in the long run in the absence of any discretionary policy action. (f) Now assume instead the government increases spending without changing taxes to close the recessionary gap. What effect will this policy have on the national debt? (g) Draw a correctly labeled graph of the loanable funds market and show the effect of the change in the national debt…
During the early 1990’s, Japan experienced an asset price bubble collapse followed by a massive decrease in economic activity. At that time, Japanese inflation was running at 1.76% a)Assuming that inflation expectations in Japan were equal to the previous period’s inflation rate, show (and explain), using the multiplier model, the labour market model, and the Phillips Curve, how the abovementioned asset price bubble collapse led to drop in economic activity in the short-run and deflationary pressure into the medium run (MR), ceteris paribus b) Explain the concept of the zero lower bound, and show how it can lead to a deflationary spiral. Use the Fisher equation to aid your explanation.
. Explain how the original Phillips curve was transformed into the expectations augmented Phillips curve. Using the latter, describe why any expansionary policy would not be effective in the long run and move the macro-economy back to the Natural Rate of Unemployment (NRU).
What kind of changesin the economy might infuence the slope of the Phillips curve?
If expected inflation decreases, does the short-run Phillips curve shift? If so, what direction does it shift? Does the long-run Phillips curve shift? If so, what direction does it shift?
“The more people at work, the higher their bills” The Phillips Curve shows the correlation between unemployment and inflation.” In the light of this statement,(a) Draw the short-run trade-off between inflation and unemployment. How might the Central Bank move the economy from one point on this curve to another? (b) Draw the long-run trade-off between inflation and unemployment. Explain how the short-run and long-run trade-offs are related. (c) Illustrate the effects of the following developments on both the short-run and long-run Phillips curves. Give the economic reasoning underlying your answers.1. A rise in the natural rate of unemployment.2. A decline in the price of imported oil.
How can you show an output gap on the vertical phillips curve model?(can use the full inflation targeting model if that helps)
Using the Frieman-Phelps expectations-augmented Phillips curve, if actual and expected inflationare equal to each other, thenA)workers are correctly forecasting inflation and the economy is in long run equilibriumB)the policymaker needs to pursue expansionary policy to create more output.C)in the long run workers will adjust their expectations, resulting in a business cycle in the longrun.D)the economy is in an expansion above the natural rate of output.
Assume the United States economy is in recession. (a) Explain the effect of the recession on: (i) short-run price level (ii) short-run output (iii) unemployment (b) If 78% of newly unemployed workers are optimistic that they can return to their jobs, what impact will that have on the macroeconomy? Explain. (c) Assume the United States implements a combination of expansionary fiscal and monetary policies. In the absence of complete crowding out, what will be the effect of these policies on each of the following? (i) Aggregate demand in the United States. Explain. (ii) The price level in the United States. Explain. (iii) Interest rates in the United States. Explain. (d) The US Government decides to enact $100 billion in fiscal stimulus. Assume that the marginal propensity to consume is 0.5. (i) What is the impact on GDP of $100 billion in government checks? (ii) What is the impact of GDP of $100 billion in government spending on infrastructure and purchases of agricultural…
