What is the natural rate of unemployment? (please answer in the form 0.xxxx (which 4 digital places), e.g. 0.1234 representing 12.34%) Answer: The original Phillips curve implied or assumed that Select one: Q a. The actual and expected rates of inflation would always be equal b. The expected rate of inflation would be zero c. none of the other alternatives is correct d. The markup over labour costs was negative 0000 e. The markup over labour costs was zero Label the following statement as true or false: The natural rate of unemployment is unaffected by (government) policy changes. Select one: 0 True 0 False For this question assume that a is equal to 8, the markup (m) is 0.6 and that the value of the catch-all variable 2 is 0.4. What is the natural level of unemployment? (please answer in the form 0.xxxx (which 4 digital places), e.g. 0.1234 representing 12.34%) Answer: For this question, assume that the Phillips curve equation is represented by the following: :z,x,1=m+zau, Which of the following will cause a reduction in the natural rate of unemployment? Select one: Q a. an increase in m 0 b. an increase in 2 Q) C. an increase in expected ination Q d. an increase in o 0 e. an increase in actual inflation Match the correct answer to each question An increase in public spending J Choose... shifts the PC curve down will change if taxes change does not shift the PC curve shifts the PC curve upwards is the same in all countries will change if either the mark-up m or catch-all variable 2 change The natural rate of unemployment Previous .a:e
