“…In a standard asset pricing equilibrium one can then write down the Euler equations of the agents, aggregate them and use the market data on returns, asset prices and market beliefs for a full identification. Recent examples of work where this has been done include Fan (2005) and Kurz and Motolese (2005). These papers show that with data on asset returns and market belief an asset pricing theory leads to specific testable restrictions.…”

“…Individual beliefs will probably not even be identifiable ex post, although aggregates of beliefs, like market sentiments, can certainly be identified (see e.g. Fan 2005, 2006). Thus, even with the full knowledge about agents' preferences over sure consumption, the individual cannot know exactly how agents will react to a particular institution 9…”
We studythe optimal choice of exchange rate regime when agents have beliefs that are mutually inconsistent. A general framework for identifying optimal policies in such situations is proposed and then used to compare fixed and floating exchange rate regimes. Agents are assumed to have diverse rational beliefs (rather than rational expectations), implying the prevalence of (rational) overconfidence. We argue that in such a situation, in comparing economic institutions, one should employ the concept of ex-post optimality rather than that of Pareto optimality. Fixing the exchange rate is ex-post optimal because it eliminates mistaken actions (based on mistaken beliefs).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
