Consider an economy where the nominal wage rate is set by wage bargaining before production. The nominal wage Wₜ=Pₜ^eF(uₜ,Aₜ) with Fᵤ<0,F_A>0; producers set price as a constant markup Pₜ=(1+μ)Wₜ; inflation πₜ=(Pₜ-Pₜ₋₁)/Pₜ₋₁ and expected inflation πₜ^e=(Pₜ^e-Pₜ₋₁)/Pₜ₋₁. Which of the following equations represents the relationship between expected rate of inflation and actual rate of inflation? (A) πₜ=(1+πₜ^e)[F(uₜ,Aₜ)-μ]-1 (B) πₜ=(1+πₜ^e)(1+μ)F(uₜ,Aₜ)-1 (C) πₜ=πₜ^e(1+μ)F(uₜ,Aₜ) (D) None of the above
Also written as: Consider an economy where the nominal wage rate is set by wage bargaining before production. The nominal wage W_t=P_t^eF(u_t,A_t) with F_u<0,F_A>0; producers set price as a constant markup P_t=(1+mu)W_t; inflation pi_t=(P_t-P_(t-1))/(P_(t-1)) and expected inflation pi_t^e=(P_t^e-P_(t-1))/(P_(t-1)). Which of the following equations represents the relationship between expected rate of inflation and actual rate of inflation?
