This paper purports to provide some evidence on the effect of rating agencies on herding in financial markets. By means of a laboratory experiment, we investigate the effect and interaction between private and public information. Previous experiments showed that lemmings behaviour can survive in...

While a basic theoretical principle in public economics assumes that individuals’ behaviour is fully-optimizer with respect to the introduction of a tax, an increasing body of research is presenting evidence that agents decision making is often affected by non-negligible cognitive biases,...

We investigate, by mean of a lab experiment, a market inspired by two strands of literature on one hand we have herd behaviour in non-market situations, and on the other hand aggregation of private information in markets. The former suggests that socially undesirable herd behaviour may result...

In this paper, we first replicated Harrison et al. (2012). Then, we studied if the group's size has an impact on group's risk aversion. In line with Harrison et al. (2012), our results confirm that no significant differences occur between individuals and groups risk aversion in three-person...

This paper aims at providing an overview of several topics that have been addressed in the field of experimental asset markets. Rather than being exhaustive in any single topic, this review is meant to gather the several research strands, and to provide a powerful picture of the main advances on...

The theoretical approach in dealing with the aggregation of information in markets in general, and financial markets in particular considers information as an exogenous element to the system, focusing just on conditions and consequences of the efficient incorporation of information into prices....

Seminal models of herd behaviour and informational cascades point out existence of negative information externalities, and propose to 'destroy' information in order to achieve social improvements. Although in the last years many features of herd behaviour and informational cascades have been...
