The phillips curve depicts relationship between real and nominal interest

Phillips curve: A graph that shows the inverse relationship between the rate of . The Phillips curve depicts the relationship between inflation and unemployment rates. This way, their nominal wages will keep up with inflation, and their real. Borrowers benefit from deflation, as the value of their debt decreases in real terms. Falling prices certainly benefit consumers who have constant nominal income. Which of the following statements regarding the effects of an interest rate rise is The diagram depicts the Phillips curve and the indifference curves of an. Adjusting Nominal Values to Real Values · Tracking Real GDP over Time . Rather, the real-world AS curve is very flat at levels of output far below A Phillips curve illustrates a tradeoff between the unemployment rate and the This chart shows the negative relationship between unemployment and inflation.

For example, if unemployment was high and inflation low, policymakers could stimulate aggregate demand. This would help to reduce unemployment, but cause a higher rate of inflation. In the s, there seemed to be a breakdown in the Phillips curve as we experienced stagflation higher unemployment and higher inflation. The Phillips Curve was criticised by monetarist economists who argued there was no trade-off between unemployment and inflation in the long run.

However, some feel that the Phillips Curve has still some relevance and policymakers still need to consider the potential trade-off between unemployment and inflation. Origins of the Phillips Curve The Phillips curve originated out of analysis comparing money wage growth with unemployment. The findings of A. Phillips in The Relationship between Unemployment and the Rate of Change of Money Wages in the United Kingdom — suggested there was an inverse correlation between the rate of change in money wages and unemployment.

For example, a rise in unemployment was associated with declining wage growth and vice versa. Original Phillips Curve Diagram This analysis was later extended to look at the relationship between inflation and unemployment. Again the s and s showed there was evidence of this inverse trade-off between unemployment and inflation.

US Unemployment and Inflation There are occasions when you can see a trade-off between unemployment and inflation. Inthe recession caused a sharp rise in unemployment and inflation became negative. Why is there a trade-off between unemployment and inflation?

Long run and short run Phillips curves

Therefore firms employ more workers and unemployment falls. However, as the economy gets closer to full capacity, we see an increase in inflationary pressures. With lower unemployment, workers can demand higher money wages, which causes wage inflation. Also, firms can put up prices due to rising demand. Therefore, in this situation, we see falling unemployment, but higher inflation. They argue that in the long run there is no trade-off as Long Run AS is inelastic.

Monetarists argue that if there is an increase in aggregate demand, then workers demand higher nominal wages. When they receive higher nominal wages, they work longer hours because they feel real wages have increased. When they realise real wages are the same as last year, they change their price expectations, and no longer supply extra labour and the real output returns to its original level.

Phillips Curve

Therefore, unemployment remains unchanged, but we have a higher inflation rate. Adaptive expectation monetarists argue there is only a short-term trade-off between unemployment and inflation. Rational expectation monetarists argue there is no trade-off, even in the short term. The rational expectation model suggests that workers see an increase in AD as inflationary and so predict real wages will stay the same.

Summary of Monetarist v Keynesian view A monetarist would argue unemployment is a supply side phenomena. Monetarists argue using demand-side policies can only temporarily reduce unemployment by an ever-accelerating inflation rate. The Phillips curve given by A. Phillips shows that there exist an inverse relationship between the rate of unemployment and the rate of increase in nominal wages.

A lower rate of unemployment is associated with higher wage rate or inflation, and vice versa. In other words, there is a tradeoff between wage inflation and unemployment.

Due to greater bargaining power of the trade union, wage increases. Thus, decrease in unemployment leads to increase in the wage Fig.

But when wage increases, the firms cost of production increases which leads to increase in price. Therefore it is also called wage inflation, that is, decrease in unemployment leads to wage inflation. The Phillips Curve shows that wages and prices adjust slowly to changes in AD due to imperfections in the labour market.

This will cause the wage rate to increase, but when wage increases, prices will also increase and eventually the economy will return back to the full-employment level of output and unemployment. Similarly, any attempt to decrease unemployment will aggravate inflation.

The Phillips Curve (Explained With Diagram)

Thus, the negative sloped Phillips Curve suggested that the policy makers in the short run could choose different combinations of unemployment and inflation rates. In the long run, however, permanent unemployment — inflation trade off is not possible because in the long run Phillips curve is vertical.

Since in the short run AS curve Phillips Curve is quite flat, therefore, a trade off between unemployment and inflation rate is possible. It offers the policy makers to chose a combination of appropriate rate of unemployment and inflation.
