Prior to the mid-1970s, many economists thought a higher rate of unemployment would reduce the inflation rate. Why? How does the modern view of the Phillips curve differ from the earlier view?
Do you think the Phillips curve is a useful tool for analyzing the economy today? Why or why not?
The period from the late 1990s to the winter of 2000 was marked by falling unemployment rates and falling inflation rates as well. How does economic theory explain this apparent violation of the Phillips curve model?

Explain. Suppose the unemployment rate in Canada is very high. If the relationship depicted by the Phillips Curve is true, what could the hands-on approach to economic policy do to reduce unemployment? How would such a policy affect inflation? Explain why both unemployment and inflation rose in the 1970s. 2. Consider the following scenarios and briefly explain how each scenario would affect short-run aggregate supply (SAS), long-run aggregate supply (LAS) or aggregate demand (AD) in Canada. In some situations, more than one may be affected. Canada produces larger number of university graduates who possess higher levels of education and skill.

What should happen in the short term and in the longterm?arrow_forwardAccording to the Phillips curve, there is an inverse relationship between inflation and unemployment. It is possible for policymakers to “buy” lower unemployment by allowing higher inflation. Using a Phillips curve, illustrate and explain how nationwide rioting and looting will impact the economy and why this supply shock has implications for policymakersarrow_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_forwardAs 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.
