We report an experimental test of the influence of ambiguity on behaviour in a coordination game. We study the behaviour of subjects in the presence of ambiguity and attempt to determine whether they prefer to choose an ambiguity safe option. We fi?nd that this strategy, which is not played in...

This paper studies the impact of ambiguity in the best shot and weakest link models of public good provision. The models are ?rst analysed theoretically. Then we conduct experiments to study how ambiguity affects behaviour in these games. We test whether subjects? perception of ambiguity differs...

This paper studies how updating affects ambiguity attitude. In particular we focus on generalized Bayesian updating of the Jaffray–Philippe sub-class of Choquet Expected Utility preferences. We find conditions for ambiguity attitude to be the same before and after updating. A necessary and...

Raiffa (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...

The paper examines the effect of ambiguity on contests where multiple parties expend resources to win a prize. We develop a model where contenders perceive ambiguity about their opponents’ strategies and determine how perceptions of ambiguity and attitudes to ambiguity affect equilibrium...

The paper examines the impacts of ambiguity and ambiguity attitudes on macro-economic "Big Push" model. By formally modelling ambiguity, optimism and pessimism in economic industrialization, we show the results with Keynesian flavour: sufficient optimism can create the "Big Push" to help the...

This article considers the impact of ambiguity in strategic situations. It extends the existing literature on games with ambiguity‐averse players by allowing for optimistic responses to ambiguity. We use the CEU model of ambiguity with a class of capacities introduced by Jaffrray and Philippe...

We run experiments with a stag hunt and bargaining coordination game. Using a between-subjects design, we vary the identity of the opponent between someone of the same culture or a different culture. The idea is to see whether cultural norms or identity play a part in coordination decisions. We...
