The de Finetti Theorem is a cornerstone of the Bayesian approach. Bernardo [4, p. 5] writes that its "message is very clear: if a sequence of observations is judged to be exchangeable, then any subset of them must be regarded as a random sample from some model, and there exists a prior...

We generalize de Finetti’s exchangeable Bayesian model to accommodate ambiguity. As a central motivating example, we consider a policy maker facing a cross-section of markets in which …rms play an entry game. Her theory is Nash equilibrium and it is incomplete because there are multiple...

The paper considers an agent who must choose an action today under uncertainty about the consequence of any chosen action but without having in mind a complete list of all the contingencies that could influence outcomes. She conceives of some relevant (subjective) contingencies but she is aware...

Bernardo (1996) writes that its "message is very clear: if a sequence of observations is judged to be exchangeable, then any subset of them must be regarded as a random sample from some model, and there exists a prior distribution...

Call an economic model incomplete if it does not generate a probabilistic prediction even given knowledge of all parameter values. We propose a method of inference about unknown parameters for such models that is robust to heterogeneity and dependence of unknown form. The key is a Central Limit...
