What is “ArgMax”?

ArgMax is a mathematical term used to designate the “argument of the maximum” of a given function.

More specifically, the argmax of a function, f, with respect to an argument x which can take values in a set X is:

argmax f(x) = {x* in X | f(x*) >= f(x) for all x in X}

x in X

Economists often make the assumption that firms maximize profits, or that people maximize their wellbeing. So the argmax notation is convenient in describing the optimal choice of firms and people.
