We often deal with uncertain events for which no probabilities are known. Several normative

Understanding how farmers perceive climate change risks and how this affects their
willingness to adopt adaptation practices is critical for developing effective climate change …

The recent spate of theoretical models of behaviour under ambiguity can be partitioned into
two sets: those involving multiple priors and those not involving multiple priors. This paper …
