   What is a concave function?

   • Intuitively, what Equation 2.98 requires is that the own second partial derivatives (f 11 and f 22) be sufficiently negative so that their product (which is positive) will outweigh any possible perverse effects from the cross-partial derivatives (f 12¼ f 21). Functions that obey such a condition are called concave functions.
