Why or why not?arrow_forwardTrue or false? Phillips curve represents a structural relationship between unemployment and inflation that never changes.arrow_forwardDerive the original Phillips curve and answer the following questions:a) What effect does an increase in the expected price level have on the price level?b) What effect does an increase in the unemployment rate have on the price level?c) What effect does a decrease in business competition have on inflation?d) What is the effect of liberalizing foreign trade?e) What effect does the formation of trade unions have?arrow_forward
- An economy has the following equation for the Phillips Curve: π = Eπ − 0.5(u − 6)People form expectations of inflation by taking a weighted average of the previous two years of inflation: Okun’s law for this economy is: Eπ = 0.7π−1 + 0.3π−2 (Y −Y−1)/(Y-1)=3.0−2.0(u−u−1) Th economy begins at its natural rate of unemployment with a stable inflation rate of 5 percent. 1. What is the natural rate of unemployment for this economy? 2. Graph the short-run tradeoff between inflation and unemployment that this economy faces. Label the point where the economy begins as A. 3. A fall in aggregate demand leads to a recession, causing the unemployment rate to rise 4 percentage points above its natural rate. On your graph, label the point the economy experiences that year as point B.arrow_forwardWhich of the following is true about the Phillips curve? The empirical relationship between unemployment and inflation in the US disappeared after the 1970s. This means that the theoretical Phillips curve does not represent the world well. For a researcher to identify the theoretical Phillips curve from empirical data, the economy must be subject to supply shocks. The empirical Phillips curve implies that a government must choose between either low unemployment and high inflation or high unemployment and low inflation. When inflation expectations adjust, the negative empirical correlation between inflation and unemployment might disappear.arrow_forwardTrue or false? According to the Phillips curve, in the long run there is a trade-off between inflation and unemploymentarrow_forward

How does economic theory explain this apparent violation of the Phillips curve model?arrow_forward
- Inflationary expectations are an important driver of the Phillips curve relationship. What are three different ways inflationary expectations might be modelled? Depict each graphically.arrow_forwardIllustrate the effects of the following developments on Phillips curves. Give the economic reasoning underlying your answers. a) In order to increase the amount of highly skilled labour in Indonesia, the government decided to make an online training program.
