We study the market implications of ambiguity sensitive preferences using the alpha-maxmin expected utility (alpha-MEU) model. In the standard Ellsberg framework we prove that alpha-MEU preferences are equivalent to either maxmin, maxmax or subjective expected utility (SEU). We show how...

We investigate the effect of introducing information about peer portfolios in an experimental Arrow-Debreu economy. Confirming the prediction of a general equilibrium model with inequality averse preferences, we find that peer information leads to reduced variation in payoffs within peer groups....

We study optimal portfolio choice and equilibrium asset prices induced by alpha-maxmin expected utility (alpha-MEU) models. In the standard Ellsberg framework we prove that alpha-MEU preferences are equivalent to either maxmin, maxmax or subjective expected utility (SEU). We show how ambiguity...

The information content of stock prices is analysed without imposing strong restrictions on traders' preferences and the distribution of dividends. Noise in the information contained in equilibrium prices arises from endogenous asset supply, which offsets price movements due to informed trading....

We construct an asset market in a finite horizon overlapping-generations environment. Subjects are tested for comprehension of their fundamental value exchange environment, and then reminded during each of 25 periods of its declining new value. We observe price bubbles forming when new...

This paper underscores the importance of the assessment of incentives of the main agents in a financial system as a key element in the analysis of financial system vulnerability and the surveillance over the financial system. We outline a diagnostic approach for the assessment of incentives....
