Distinguish between the short run and the long run as they relate to macroeconomics. Why is the distinction important?

Short Answer

Expert verified

The main difference between the short run and long run in macroeconomics is that the input prices are fixed in the short run, but they are flexible in the long run.

The distinction is crucial as it helps policymakers choose appropriate policies, keeping in mind the short-run and long-run impact of those policies.

Step by step solution

01

The distinction between short run and long run 

In macroeconomics, the main point of distinction between the short and long run is the responsiveness of input prices.The short-run is a period in macroeconomics when the input prices remain fixed in response to changes in output prices.This happens because the workers cannot anticipate inflation correctly, so they do not bargain for higher wages. Hence, the input prices remain unchanged in the short run.

In contrast, the long run is a period in macroeconomics when the input prices change entirely in response to a change in output prices. This happens because the workers can correctly anticipate inflation (or rise in output prices), so they bargain for higher wages. This causes wages or input prices to rise in the long run.

02

The importance of the distinction 

The distinction between the short and long run is crucial as it helps to understand the impact of various government policies in the short and long run. In other words, the economy behaves differently concerning a particular policy in the short and long run. So it helps the government to adopt appropriate monetary or fiscal policy to stabilize the economy, keeping in mind the short-run and long-run impacts of those policies.

Most popular questions from this chapter

Between 1990 and 2009, the U.S. price level rose by about 64 percent while real output increased by about 62 percent. Use the aggregate demand–aggregate supply model to illustrate these outcomes graphically.

Suppose the full-employment level of real output (Q) for a hypothetical economy is $250 and the price level (P) initially is 100. Use the short-run aggregate supply schedules below to answer the questions that follow:

AS(P100)
AS(P125)
AS(P75)
PQPQPQ
125280125250125310
100250100220100280
752207519075250

What is the level of real output in the short run if the price level unexpectedly rises from 100 to 125 because of an increase in aggregate demand? What happens if the price level unexpectedly falls from 100 to 75 because of a decrease in aggregate demand? Explain each situation, using numbers from the table.

b. What is the level of real output in the long run when the price level rises from 100 to 125? When it falls from 100 to 75? Explain each situation.

c. Illustrate the circumstances described in parts a and b on graph paper, and derive the long-run aggregate supply curve.

Suppose the government misjudges the natural rate of unemployment to be much lower than it actually is and, thus, undertakes expansionary fiscal and monetary policies to lower it. Use the concept of the short-run Phillips Curve to explain why these policies might at first succeed. Use the concept of the long-run Phillips Curve to explain these policies’ long-run outcomes.

What do the distinctions between short-run aggregate supply and long-run aggregate supply have in common with the distinction between the short-run Phillips Curve and the long-run Phillips Curve? Explain.

Which of the following statements are true? Which are false? Explain why the false statements are untrue.

a. Short-run aggregate supply curves reflect an inverse relationship between the price level and the level of real output.

b. The long-run aggregate supply curve assumes that nominal wages are fixed.

c. In the long run, an increase in the price level will result in an increase in nominal wages.
