Randomization and dynamic consistency
Raiffa (Q J Econ 75:690-694, 1961) has suggested that ambiguity aversion will cause a strict preference for randomization. We show that dynamic consistency implies that individuals will be indifferent to ex ante randomizations. On the other hand, it is possible for a dynamically consistent ambiguity...

| Summary: | Raiffa (Q J Econ 75:690-694, 1961) has suggested that ambiguity aversion will cause a strict preference for randomization. We show that dynamic consistency implies that individuals will be indifferent to ex ante randomizations. On the other hand, it is possible for a dynamically consistent ambiguity averse preference relation to exhibit a strict preference for some ex post randomizations. We argue that our analysis throws some light on the recent debate on the status of the smooth model of ambiguity This debate rests on whether the randomizations implicit in the set-up are viewed as being resolved before or after the (ambiguous) uncertainty. |
