The Phillips curve is a relationship between the unemployment rate and the rate of InflationInflation in an economy. It was first proposed by A.W. Phillips in 1958, and it has been a subject of much debate and controversy ever since.
The Phillips curve suggests that there is a trade-off between inflation and unemployment. In other words, if the government wants to reduce unemployment, it must accept higher inflation, and vice versa.
However, the Phillips curve has not always been reliable. In the 1970s, the United States experienced StagflationStagflation, a period of high unemployment and high inflation. This led many economists to believe that the Phillips curve was no longer valid.
In recent years, there has been renewed interest in the Phillips curve. Some economists believe that the curve may be valid again, while others believe that it is still unreliable.
The following are some of the subtopics related to the Phillips curve:
- The original Phillips curve
- The expectations-augmented Phillips curve
- The natural rate of unemployment
- Stagflation
- The NAIRU
- The Phillips curve in the United States
- The Phillips curve in other countries

The original Phillips curve was a simple relationship between the unemployment rate and the rate of inflation. Phillips found that there was a negative relationship between these two variables, meaning that when unemployment was low, inflation tended to be high, and vice versa.
This relationship was based on data from the United Kingdom from the 1950s and 1960s. However, it soon became clear that the Phillips curve was not as reliable as it had first appeared. In the 1970s, the United States experienced stagflation, a period of high unemployment and high inflation. This led many economists to believe that the Phillips curve was no longer valid.
In the 1970s, Milton Friedman and Edmund Phelps proposed the expectations-augmented Phillips curve. This curve suggests that the relationship between inflation and unemployment is not as simple as the original Phillips curve suggested. Instead, the expectations-augmented Phillips curve suggests that inflation is determined by both the unemployment rate and the expected rate of inflation.
In other words, if workers expect inflation to be high, they will demand higher wages, which will lead to higher prices and higher inflation. This means that the government cannot simply reduce unemployment without also taking steps to reduce inflation expectations.
The natural rate of unemployment is the rate of unemployment that is consistent with stable prices. In other words, it is the rate of unemployment at which there is no upward or downward pressure on inflation.
The natural rate of unemployment is determined by a number of factors, including the structure of the labor market, the level of government benefits, and the minimum wage.
Stagflation is a period of high unemployment and high inflation. It is a situation in which the economy is not growing, but prices are rising.
Stagflation is a difficult problem to solve, because the traditional tools of monetary and Fiscal Policy are not effective in addressing both unemployment and inflation at the same time.
The NAIRU is the non-accelerating inflation rate of unemployment. It is the rate of unemployment below which inflation is expected to rise.
The NAIRU is determined by a number of factors, including the natural rate of unemployment, the level of productivity, and the structure of the labor market.
The Phillips curve in the United States has been relatively stable since the 1980s. However, there have been periods of time when the curve has shifted. For example, the curve shifted to the right in the 1970s, during the period of stagflation.
The Phillips curve in other countries has also been relatively stable. However, there have been some differences in the way that the curve has behaved in different countries. For example, the curve has been more stable in Europe than in the United States.
The future of the Phillips curve is uncertain. Some economists believe that the curve will continue to be relevant, while others believe that it will become less important. The future of the Phillips curve will depend on a number of factors, including the behavior of inflation and unemployment, the structure of the labor market, and the policies of governments.
Here are some frequently asked questions about the Phillips curve:
-
What is the Phillips curve?
The Phillips curve is a relationship between the unemployment rate and the rate of inflation in an economy. It was first proposed by A.W. Phillips in 1958, and it has been a subject of much debate and controversy ever since. -
What does the Phillips curve suggest?
The Phillips curve suggests that there is a trade-off between inflation and unemployment. In other words, if the government wants to reduce unemployment, it must accept higher inflation, and vice versa. -
Why is the Phillips curve important?
The Phillips curve is important because it helps policymakers understand the relationship between inflation and unemployment. This understanding can help policymakers make decisions about how to manage the economy. -
What are the limitations of the Phillips curve?
The Phillips curve has a number of limitations. First, it is based on the assumption that there is a trade-off between inflation and unemployment. However, this assumption has not always been borne out by experience. Second, the Phillips curve is based on the assumption that inflation is caused by demand-pull factors. However, inflation can also be caused by cost-push factors, such as an increase in the price of oil. Third, the Phillips curve is based on the assumption that workers are willing to trade off higher inflation for lower unemployment. However, this assumption may not always be true. -
What is the future of the Phillips curve?
The future of the Phillips curve is uncertain. Some economists believe that the curve may be valid again, while others believe that it is still unreliable. The future of the Phillips curve will depend on a number of factors, including the behavior of workers, businesses, and policymakers.
Here are some subtopics related to the Phillips curve:
- The original Phillips curve: The original Phillips curve was proposed by A.W. Phillips in 1958. It showed a negative relationship between the unemployment rate and the rate of inflation. In other words, the curve suggested that there was a trade-off between inflation and unemployment.
- The expectations-augmented Phillips curve: The expectations-augmented Phillips curve was developed in the 1970s. It takes into account the fact that workers and businesses form expectations about future inflation. These expectations can affect the current rate of inflation.
- The natural rate of unemployment: The natural rate of unemployment is the rate of unemployment that is consistent with stable inflation. It is the rate of unemployment at which there is no upward or downward pressure on inflation.
- Stagflation: Stagflation is a period of high unemployment and high inflation. It is a situation in which the Phillips curve does not hold.
- The NAIRU: The NAIRU is the non-accelerating inflation rate of unemployment. It is the rate of unemployment below which inflation is expected to accelerate.
- The Phillips curve in the United States: The Phillips curve has been observed in the United States since the 1950s. However, the relationship between inflation and unemployment has changed over time. In the 1960s and 1970s, the Phillips curve was relatively flat. This meant that there was a small trade-off between inflation and unemployment. However, in the 1980s and 1990s, the Phillips curve became steeper. This meant that there was a larger trade-off between inflation and unemployment.
- The Phillips curve in other countries: The Phillips curve has also been observed in other countries. However, the relationship between inflation and unemployment has varied across countries. In some countries, the Phillips curve has been relatively flat, while in other countries, it has been relatively steep.
- The future of the Phillips curve: The future of the Phillips curve is uncertain. Some economists believe that the curve may be valid again, while others believe that it is still unreliable. The future of the Phillips curve will depend on a number of factors, including the behavior of workers, businesses, and policymakers.
Question 1
The Phillips curve is a relationship between the unemployment rate and the rate of inflation in an economy. It was first proposed by A.W. Phillips in 1958, and it has been a subject of much debate and controversy ever since.

However, the Phillips curve has not always been reliable. In the 1970s, the United States experienced stagflation, a period of high unemployment and high inflation. This led many economists to believe that the Phillips curve was no longer valid.
In recent years, there has been renewed interest in the Phillips curve. Some economists believe that the curve may be valid again, while others believe that it is still unreliable.
Which of the following is not a subtopic related to the Phillips curve?
(A) The original Phillips curve
(B) The expectations-augmented Phillips curve
(CC) The natural rate of unemployment
(D) Stagflation
(E) The NAIRU
Answer
(D) Stagflation
Stagflation is a period of high unemployment and high inflation. It is not a subtopic related to the Phillips curve.
Question 2
The expectations-augmented Phillips curve is a model that incorporates the expectations of workers into the Phillips curve. It suggests that the rate of inflation is determined by the unemployment rate and the expected rate of inflation.
Which of the following is not an assumption of the expectations-augmented Phillips curve?
(A) Workers have rational expectations.
(B) The natural rate of unemployment is constant.
(C) The rate of inflation is determined by the unemployment rate and the expected rate of inflation.
(D) The expected rate of inflation is determined by the past rate of inflation.
(E) The Phillips curve is downward-sloping.
Answer
(E) The Phillips curve is downward-sloping.
The expectations-augmented Phillips curve is a model that incorporates the expectations of workers into the Phillips curve. It suggests that the rate of inflation is determined by the unemployment rate and the expected rate of inflation. The Phillips curve is not necessarily downward-sloping.
Question 3
The natural rate of unemployment is the rate of unemployment that is consistent with stable prices. It is the rate of unemployment at which there is no upward or downward pressure on inflation.
Which of the following is not a factor that can affect the natural rate of unemployment?
(A) The level of government spending
(B) The level of productivity
(C) The structure of the labor market
(D) The level of unionization
(E) The level of immigration
Answer
(A) The level of government spending
The natural rate of unemployment is the rate of unemployment that is consistent with stable prices. It is the rate of unemployment at which there is no upward or downward pressure on inflation. The level of government spending is not a factor that can affect the natural rate of unemployment.
Question 4
Stagflation is a period of high unemployment and high inflation. It is a situation in which the economy is experiencing both high unemployment and high inflation.
Which of the following is not a cause of stagflation?
(A) Supply shocks
(B) Demand shocks
(C) Cost-push inflation
(D) Demand-pull inflation
(E)
Answer
(E) Monetary policy
Monetary policy is the use of interest rates and other tools to control the MoneyMoney-supplyMoney Supply. It is not a cause of stagflation.

Which of the following is not a way to reduce the NAIRU?
(A) Increase productivity
(B) Reduce the level of unionization
(C) Increase the flexibility of the labor market
(D) Increase the level of immigration
(E) Reduce the level of government spending
Answer
(A) Increase productivity
The NAIRU is the non-accelerating inflation rate of unemployment. It is the rate of unemployment below which inflation is expected to accelerate. Increasing productivity is not a way to reduce the NAIRU.
