Plain-text version
Suppose the following equation holds for an economy at every time t: Pₜ=(1+a)WₜNₜ/Yₜ. That is, the price of output is a fixed markup over unit labour cost. Let π be the inflation rate, w the wage inflation rate, and λ the rate of growth in labour productivity (labour productivity =Yₜ/Nₜ). Which of the following is true? (A) w=π-λ (B) π=w+λ (C) π=w-λ (D) w=λ-π
Also written as: Suppose the following equation holds for an economy at every time t: P_t=(1+a)W_tN_t/Y_t. That is, the price of output is a fixed markup over unit labour cost. Let pi be the inflation rate, w the wage inflation rate, and lambda the rate of growth in labour productivity (labour productivity =Y_t/N_t). Which of the following is true?
