Supermodularity and preferences

چکیده
We uncover the complete ordinal implications of supermodularity on finite lattices under the assumption of weak monotonicity. In this environment, we show that supermodularity is ordinally equivalent to the notion of quasisupermodularity introduced by Milgrom and Shannon. We conclude that supermodularity is a weak property, in the sense that many preferences have a supermodular representation.

Supermodularity is not Falsifiable∗
Supermodularity has long been regarded as a natural notion of complementarities in individual decision making; it was introduced as such in the nineteenth century by Edgeworth and Pareto. But supermodularity is not an ordinal property. We study the ordinal content of assuming a supermodular utility, i.e. what it means for the individual’s underlying preferences. We show that supermodularity is ...
متن کاملIncomplete preferences, complementarity and non-convexity
This paper extends to incomplete preferences the formulation of strategic complementarity in Milgrom and Shannon (1994). It is shown, by example, that quasi-supermodularity and single-crossing no longer su¢ce to guarantee monotone comparative statics with incomplete preferences. However, when incomplete preferences satisfy monotone closure in addition to quasi-supermodularity and single-crossin...
متن کاملComplementarity with incomplete preferences
This paper extends the formulation of complementarity in Milgrom and Shannon (1994) to the case of incomplete but acyclic preferences. It is shown that the problem can be reformulated as one with complete but intransitive preferences. In this case, quasi-supermodularity and single-crossing on their own do not guarantee either monotone comparative statics or equilibrium existence in pure strateg...
متن کاملSupermodularizability *
We study the ordinal content of assuming supermodularity, including conditions under which a binary relation can be represented by a supermodular function. When applied to revealed-preference relations, our results imply that supermodularity is some times not refutable: Choices on consumption at different prices can be rationalized with a supermodular utility if they can be rationalized. Hence,...
متن کاملSupermodularity and risk aversion
In this paper, we consider the relationship between supermodularity and risk aversion. We show that supermodularity of the certainty equivalent implies that the certainty equivalent of any random variable is less than its mean. We also derive conditions under which supermodularity of the certainty equivalent is equivalent to aversion to mean-preserving spreads in the sense of Rothschild and Sti...
