Strictly quasiconcave
Did you know?
WebIIf f is a monotonic transformation of a concave function, it is quasi-concave. This also means that if a monotonic transformation of f is concave, then f is concave. IExample: Check whether the f(x;y) = xy + x2y2+ x3y3 de ned on <2 +is quasiconcave. Note that f(x) = g(u(x;y)) where u(x;y) = xy and g(z) = z + z2+ z3.
