Temporal resolution of uncertainty: Risk vs. Ambiguity

Abstract

Several studies examine attitudes towards temporal resolution of risk, but much less is known about how people value the timing of resolution of ambiguity. We introduce a unified framework to measure preferences towards delayed risk, immediate ambiguity, and delayed ambiguity, using a common scale: matching probabilities. An incentivized laboratory experiment illustrates the approach and shows that preference for early resolution is stronger under ambiguity than under risk.
