Well there is the [Lagrange multiplier test](http://www.cemfi.es/~arellano/lmtesting.pdf) in econometrics.

In my own studies I have noticed that many of the constrained optimization type questions that are often covered in intermediate/advanced microeconomics courses are seldom seen in more empirical types of work.

under what circumstances would I apply the use of the Lagrangian multiplier technique to an real world problem?
