A Nash equilibrium can also be seen as a Cournot-Nash equilibrium, though this is debated because Cournot provided a specific application, not a general formulation. In my view, another of Nash's fundamental contributions stands out when contrasting him to Cournot. Cournot treated economic...

This paper generalizes a result by Samet concerning iterated expectations and common priors. When a player in some state of the world is allowed to ascribe probability zero to that state, something not allowed in Samet's framework, iterated expectations may not converge, and when they do, common...

This paper analyzes farsighted stable sets when agents have heterogeneous expectations over the dominance paths. We consider expectation functions satisfying two properties of path-persistence and consistency. We show that farsighted stable sets with heterogeneous expectations always exist and...

This paper analyzes farsighted stable sets when agents have heterogeneous expectations over the dominance paths. We consider expectation functions satisfying the two properties of justifiability and maximality and define stable alternatives as endpoints of the expectation function of some agent...

Delusional beliefs are seen in association with a number of neuropathological conditions, including schizophrenia, dementia, and traumatic brain injury. A key distinction exists between polythematic delusion (here the patient exhibits delusional beliefs about a variety of topics that are...

This paper analyzes farsighted stable sets when agents have heterogeneous expectations over the dominance paths. We consider expectation functions satisfying two properties of justifiability and maximality. We characterize singleton farsighted stable sets with heterogeneous expectations in...
