托您的福, 為了解答您的問題, 我回去翻了一下 Mas-Colell et al. 的大作,
稍稍喚醒了個人的一些回憶. 那個我還對個體理論有著高度熱忱的時光啊...
總之為了感謝您, 我抄一段 Mas-Colell et al. 給您看.
Definition:
A monotone preference relation "at least as good as" on X = R_+^L
is homothetic if all indifference sets are related by proportional
expansion along rays; that is, if x is indifferent to y, then
alpha*x is indifferent to alpha*y for any alpha >= 0.
