摘要
In economics, homothetic functions are production functions whose marginal technical rate of substitution is homogeneous of degree zero. Mathematically, a homothetic function is a function of the form f(x) = F((h(x(1),, x(n))), where F is a monotonically increasing function and h is a homogeneous function of any degree d not equal 0. In this paper, we classify homothetic functions satisfying the homogeneous Monge-Ampere equation. Several applications to production models in economics will also be given. (C) 2013 Elsevier Inc.
