The behavioural finance literature attributes the persistent market misvaluation observed in real data to the presence of deviations from rational thinking of the actors involved. Cognitive biases and the use of simple heuristics can be described using expected utility maximising agents that...

We consider a market economy where two rational agents are able to learn the distribution of future events. In this context, we study whether moving away from the standard Bayesian belief updating, in the sense of under-reaction to some degree to new information, may be strategically convenient...

Measuring beliefs about natural disasters is challenging. Deep out-of-the-money options allow investors to hedge at a range of strikes and time horizons, thus the 3-dimensional surface of firm-level option prices provides information on (i) skewed and fat-tailed beliefs about the impact of...

Previous research has documented strong peer effects in risk taking, but little is known about how such social influences affect market outcomes. The consequences of social interactions are hard to isolate in financial data, and theoretically it is not clear whether peer effects should increase...

Financial knowledge and the investment in information of retail investors have been under scrutiny on the side of regulators and of academics. Actually, increasing financial literacy of individuals is one of the promising avenues in order to increase financial markets participation. In this...

Two types of agents have diverse beliefs about the law of motion for an exogenous endowment. One type knows the true law of motion and the other learns about it via Bayes' theorem. Financial market structure affects the dynamics of the distribution of financial wealth. When markets are complete,...

In a financial market where agents trade for short-term profit and where news can increase the uncertainty of the public belief, there are strategic complementarities in the acquisition of private information and, if the cost of information is sufficiently small, a continuum of equilibrium...

Previous research has documented strong peer effects in risk taking, but little is known about how such social influences affect market outcomes. Since the consequences of social interactions are hard to isolate in financial data, we design an experimental asset market with multiple risky assets...

We experimentally investigate how price expectations are formed in a large asset market where subjects' only task is to forecast the future price of a risky asset. The realized prices depend on these expectations. We observe small (6 participants) and large markets (about 100 participants). In...

The paper studies the emergence of contrarian behavior in information networks in an asset pricing market. Financial traders coordinate on similar behavior, but have heterogeneous price expectations and are influenced by friends. According to a popular belief, they are prone to herding. However,...
