Problem 1. (40 POINTS) Consider the Solow growth model with constant population ($\frac{\dot{L}}{L} = 0$) and with technology progress ($\frac{\dot{A}}{A} = g$).
a) Define the steady state condition using one equation. Represent it graphically.
b) Show the effects of a decrease in the saving rate $s$ and an increase in the depreciation rate of capital $\delta$ in two separate graphs. Briefly describe how the growth rates of capital and output per effective labor (i.e. $g_k$ and $g_y$) change during two adjustment processes?
c) Assume the production function $Y = K^{0.5}(AL)^{0.5}$, $\delta = 0.05$, and $g = 0.02$. If per effective labor production is 10, what is the equilibrium value of $s$?
