I DONT NEED HELP ON 3.1-3.2! Only solve for Elasticity of Y in respect to G_1 (3.3 Only) Thanks in advance. Solve only 3.3
3.1 Writing down the problem
A firm has N inputs: G₁, G₂,...GN. The cost to rent/hire the i'th input (G₂) is p. The firm has
a multi-input Cobb-Douglas production function, where the exponent of the i'th input is y
Y = A-II (G¹) = A x G xGT. GW
The price of output is p. So, if the firm makes Y units of output, their revenue would be pY. The
firm has to pay for all inputs, however, all inputs except for G₁ are fixed. This means the firm only
chooses G₁. Write down the firm's profit maximization problem.
3.2 Finding the optimal level of input
1. Solve the problem you just formulated analytically.
2. Solve the problem you just formulated by "brute-force" at y₁ = 0.36, A = 1, G; = 1 for all
i>1, p₁ = 0.05, p =1. Use MATLAB to evaluate profit along a grid of 100 G₁ choices and
find the peak profit level. Use MATLAB to visualize the results.
3. Would there be an optimal choice if >1?
3.3 Elasticity
What is the elasticity of Y with respect to G₁, i.e., the sensitivity of output to input. G₁?
