Concavity of Cobb-Douglass Utility Function on Non-Open set
My textbook argues that the Cobb-Douglass utility function $u=(x1)^a(x2)^b$ with $a,b>0$ and $a+b<1$ is concave on $R2+$ by computing the Hessian and showing it to be negative semidefinite for ...

Calculating elasticity between log term and non-log term [duplicate]
Given the following, I am asked to calculate the elasticity of wages with respect to age:
$$ππ(π€_π)=π½_1+π½_2πππ_i+π½_3πππ^2_π+π½_4π_π+π½_5π_π+π½_6πππ_π+π_π$$

What problems arise when the minimum wage is directly linked to the inflation rate?
For example if the minimum wage is 10, and the inflation for the year is 3%, then next year the minimum wage is 10*1.03 =10.30. the next year, inflation is 5%, so the minimum wage becomes 10.82.
The ...

Supporting Hyperplane Theorem and quasiconcave utility function
My notes says that if $u(.)$ is strictly quasiconcave and differentiable, by the supporting hyperplane theorem, there exists $p >>0$ and $w \geq 0$ such that $ x = x(p,w)$ $\forall x$. I am ...
