Most models of ambiguity aversion satisfy Anscombe-Aumann's Monotonicity axiom. Monotonicity imposes separability of preferences across events that occur with unknown probability. We construct a test of Monotonicity by modifying the Allais paradox to a setting with both subjective and objective...

Most models of ambiguity aversion satisfy Anscombe-Aumann's Monotonicity axiom. This paper proposes a test of Monotonicity, the Allais Horse Race. It is an adaptation of the Allais paradox to a setting with both subjective and objective uncertainty. Viewed as a thought experiment, the Allais...

Firms often discourage certain categories of individuals from buying their products, seemingly at odds with typical assumptions about profit maximization. This paper provides a potential rationale for such firm behavior: Consumers seek to signal that they have "desirable" ideological values to...

Firms often discourage certain categories of individuals from buying their products, in contrast with typical assumptions about profit maximization. This paper provides a potential rationale for such firm behavior: consumers seek to signal that they have "good" moral values to themselves and...

Ambiguous prospects are ubiquitous in social and economic life, but the psychological foundations of behavior under ambiguity are still not well understood. One of the most robust empirical regularities is the strong correlation between attitudes towards ambiguity and compound risk which...
