As I understand it, the Lagrange multiplier is always positive. Can it be negative?

If you have a purely geometric problem of maximizing or minimizing some function $f$ under a constraint $g=0$ then some people set up the auxiliary function $\Phi:=f-\lambda g$, and other people define $\Phi:=f+\lambda g$. Both will of course obtain the same conditionally stationary points of $f$, but the sign of $\lambda$ in these points will be opposite for the two.
If however the problem at stake comes from a physical or economical context then it is sometimes possible to give the $\lambda$ a meaning in this context, in so far as there is a clear cut "positive side" of $g$. People then speak about "virtual forces" or "shadow prices".
