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). 1. There is a fall in the natural rate of unemployment. 2. There is a decline in expected inflation. 3. There is a fall in government spending. 4. There is a rise in the price of imported oil.
The following graph plots the short-run and long-run Phillips curves (SRPC and LRPC, respectively) for an economy currently experiencing long-run macroeconomic equilibrium at point A, where the natural unemployment rate is 6% and the inflation rate is 8% per year. Suppose that the central bank for this economy has decided that inflation is too high and thus wants to decrease the inflation rate by 6 percentage points per year. A reduction in the rate of inflation is known as (deflation/disinflation) . To reduce inflation from 8% to 2% in the short run, the central bank would have to accept an unemployment rate of ____% True or False: If people have rational expectations, the economy may not have to endure an unemployment rate as high as predicted by the short-run Phillips curve. -True -False
Assuming the long-run Phillips curve is vertical, a consistent increase in money supply over a period of years will _________________ the unemployment rate and will _________________ the inflation rate? a) decrease; increase b) increase; decrease c) increase; have no effect on d) decrease; decrease e) have no effect on; increase
For this question, assume that the Phillips curve equation is represented by the following equation: πt - πt-1 = (m + z) - αut. A reduction in the unemployment rate will cause A) a reduction in the markup over labor costs (i.e., a reduction in m). B) an increase in the markup over labor costs. C) an increase in the inflation rate over time. D) a decrease in the inflation rate over time. E) none of the above
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). (Please use the image attached) 1. There is a rise in the price of imported oil. 2. There is a fall in government spending.
The following graph depicts the short-run and long-run Phillips curves (SRPC and LRPC) for a hypothetical economy in long-run macroeconomic equilibrium at point A, where the natural unemployment rate is 6% and the current inflation rate is 8% per year.
Why do the unexpected inflation and output gap axes need to extend into the negative regions in the Phillips curve diagram? Group of answer choices Both output gaps and unexpected inflation can be negative or positive. Both output gaps and unexpected inflation always begin by being negative. Negative inflation gaps are very common. Negative output gaps are very common.
As with demand and supply analysis, changes in the economy can cause both shifts of and movements along the short-run Phillips curve. Which of the following would cause a shift of the short-run Phillips curve? Check all that apply. An increase in government spending A decrease in short-run aggregate supply An increase in the expected inflation rate
Does the short-run Phillips curve have a positive or negative slope? Explain how this slope is derived.
Graphically derive short run Phillips curve with the help of aggregate demand and supply and demand.
The long−run Phillips curve is a ________ curve, and moving along the long−run Phillips curve an increase in the inflation rate is associated with ________ in the natural unemployment rate. A. horizontal; no change B. downward sloping; no change C. downward sloping; a decrease D. vertical; no change E. upward sloping; an increase
The following graph plots the long-run Phillips curve (LRPC) and short-run Phillips curve (SRPC1SRPC1) for an economy currently experiencing long-run equilibrium at point A (grey star symbol). Which of the following is true along SRPC1SRPC1? -The actual unemployment rate is 6%. -The expected inflation rate is 5%. -The actual inflation rate is 5%. -The natural rate of unemployment is 3%. Suppose that the central bank for this economy suddenly and unexpectedly decreases the money supply in an effort to reduce inflation. As a result of this unanticipated policy action, actual inflation falls to 3%. On the previous graph, use the black point (plus symbol labeled "B") to illustrate the short-run effects of this policy. Suppose that now, after a period of 3% inflation, households and firms begin to expect that the inflation rate will persist at the level of 3%. On the previous graph, use the purple line (diamond symbol) to draw SRPC2SRPC2, the short-run Phillips curve that is…
