Question
In the first problem set, you studied the constant elasticity of substitution (CES) production function
Y = zF(K, N):
Y = z [0(aK)" + (1 – 0)(BN)"]*
where Y is output, the constant z measures productivity, K is physical capital, N is labor, 0 <0 <1
and y are parameters and 0 <a < 1, 0 < 3 <1 represent the capital and labor shares, respectively.
