Return to scale of a production function, $q = L^\lambda + K^\gamma$, is determining it possible in that general form?

Given the production function $q = L^\lambda + K^\gamma$, how do we determine the return to scale for different value of $\lambda$ and $\gamma$? I know we have to determine the homogeneous degree of ...

How to determine if a production function in a functional form has diminishing marginal rate of technical substitution?

For production function $q(L,K) = L^\lambda + K^\gamma$ The MRST is defined as $\frac{\lambda L^{\lambda-1}}{\gamma K^{\gamma-1}}$. Is it correct and sufficient to say that in order for MRTS to be ...

question about production optimization

the question is, if Q = AK^a(HL)^b and the parameters are: (A =100) (K = 10000$) (H = 1) (L = 100 person) (a = 0.5) (b = 0.5) P = 5 per unit, R = interest rate of 3 percent per year , W = 3 per ...

Arguments for Concavity or Quasi-concavity

I'm faced with questions that want me to show that a utility or production function is either concave, or if not then quasi-concave so that we can apply the KKT conditions. For example the production ...

Mixed Partial Derivatives in Profit Function

$\pi(x,z) = p(a\ln(x) + b\ln(z)) - w_xx - w_zz$ Question 1: Using the first order conditions, we get: $x = \frac{pa}{w_x}$ $z = \frac{pb}{w_z}$ What do we call these Input demand functions as a ...

How is production managed with respect to the long run vs the short run?

Assuming perfect competition, I think that firms are price takers in the labor/capital markets as well (in the short and long run), correct? And I know that the Long-run total cost curve is derived by ...

Does global maximum of CRS Cobb-Douglas profit exist

In most macroeconomic papers it is taken as given that the aggregate prodution function is $Y=AK^{\alpha}L^{1-\alpha}$, and that the optimality conditions for inputs determine input demands: $$ \max_{...

Kuhn-Tucker conditions in linear cost minimization

Suppose we have the production function $f: \mathbb{R}^{2} \to \mathbb{R}$ given by $$ f(x,y) = ax + by $$ and input prices $p_{1}$ and $p_{2}$, and we want to minimize the cost function $p_{1}x_{1} ...
