Question:
Assume that production is a function of capital and labor, and that the rate of savings and depreciation are constant. Furthermore, assume that the production function can be described by the function:
{eq}Y = K^\frac{1}{2}L^\frac{1}{2} {/eq}
where {eq}\textbf{K} {/eq} is capital and {eq}\textbf{L} {/eq} is labor.
a. What is the per worker production function y = f(k)?
b. Solve for steady state capital per worker, production per worker, and consumption per worker with s = 0.4 and {eq}\sigma {/eq} = 0.1. (You need to set {eq}\Delta k = 0 {/eq} to get an equation in s, {eq}\sigma {/eq}, and k, then solve for k).
Capital:
Capital refers to a sum of money that investors use to set up a business. Capital is. in most cases, used to build wealth. The term is often used to describe machinery, land, and buildings that are needed to make establishments even more efficient.

The production function is: {eq}Y = K^{\frac{-1}{2}} {/eq}
Once you divide both sides by L, you will get the production function for workers to...
