The main objective of this paper is to analyze the impact of uninformative communications on asset prices. An experimental approach allows us to control for the release of a priori uninformative messages. We introduce the release of messages in standard experimental asset markets with bubbles...

In real world situations the fundamental value of an asset is ambiguous. Recent theory has incorporated ambiguity in the dividend process and the information observed by investors, and studied its effect on asset prices. In this paper we experimentally study trader reaction to ambiguity when...

Financial markets are overwhelmed by daily announcements. We use experimental asset markets to assess the impact of releasing public messages with different levels of reliability on asset prices. Subjects receive qualitative announcements in predetermined trading periods that are either preset...

We study team formation in real-effort experiments in which participants bargain over a jointly produced outcome depending both on effort and ability. Participants decide between undertaking a task alone or with another participant by releasing the minimum share of the future team outcome that...

We propose a novel approach to the analysis of organizations by developing a computerized platform that reproduces relevant features of existing organizations such as real-effort tasks and real-leisure alternative activities (Internet). In this environment, we find strong incentives effects as...

We report experiments that examine trader reaction to ambiguity when dividend information is revealed sequentially. We find that experienced traders are better at internalizing ambiguity than inexperienced subjects. No significant differences are observed in the ambiguity versus control...

"There is extensive evidence which indicates that people learn positively about themselves. We build on this finding to develop a model of team formation. We show that under complete information learning positively about oneself prevents efficient team formation. Agents becoming overconfident...
