Assumption of Monotonic Preferences
The assumption of monotonic preferences means that more is better no matter how much more.
As noted in WikiBooks (reference below):
“The monotonicity assumption translates roughly to “more is better”. Though trivial in some instances, choice sets including economic ‘bads’ such as pollution may violate monotonicity.”
“Notice that monotonicity, translating to “more is better, even for infinitesimal deviations”, implies local non-satiation, but not vice-versa.”
