The consumer price index was 100 in 1994 and 103.3 in 1995. Therefore, the rate of inflation in 1995 was about: O 3.3 percent O 2.8 percent O 4.4 percent 1 pts O 6 percent
15. Suppose that the relationship between inflation rate (π) and unemployment rate (u) is described by the following equation:
πt – πte = (m + z) – αut
where m = 0.05, z = 0.04, and α = 2. In this economy, the authorities keep unemployment rate at 4% forever.
a. If the modified Philips curve describes the relationship between π and u correctly, how should “πte” be specified? Rewrite the equation using this specification. Assume that πt–1 = 1%. Compute πt, πt+1, and πt+2.
b. Do you believe the answer in part (a)? Why or why not?
c. Derive the natural rate of unemployment.
Assume that the labor demand equation for a fictional country is L d =30-w where w is the wage per hour worked and L d is the number of workers demanded by firms. Assume also that the labor supply equation for that country is L s =0.5(w) , where L s is the number of people willing to work . [LO 9.2,9.5] a. Find the equilibrium wage and quantity of labor employed b . At the equilibrium wage , how many people are unemployed ? c. How would the number of unemployed change if the supply of workers increased ?
