1. (15 points) We have a production function which has a constant returns to scale $Y = F(A, K, L) = AK_t^\alpha L_t^{1-\alpha}$ and capital accumulation function $K_{t+1} = K_t + sY_t - \delta K_t$ (i) Define equations above (ii) Find out steady state level of capital per labor and explain this steady state level of capital per labor.
