We inquire experimentally whether asymmetric information in competitive settings and competition per se influence individual social behaviour. Participants perform a task and are remunerated according to two schemes, a non-competitive and a competitive one, then they play a standard public goods game. In the first scheme participants earn a flat re...
Experimental economics uses response times as a tool to evaluate the instinctiveness of choices and behaviours. They have been used to define types of subjects, but never to evaluate the stability of such types. This paper defines stability of types in terms of the variability exhibited by the choices made by an individual in a repeated experiment....
This paper is centred on a discussion of Gauthier’s model of Constrained Maximization in the case of uncertainty on the nature of the agents. I have looked at the effects on Constrained Maximization of considering mutual recognition between the agents who enter into interaction as a necessary condition for cooperation. The definition of Constrained...
This entry outlines what is meant by decision making under risk and uncertainty. It illustrates the model of Expected Utility, its properties and the Allais paradox as the main violation of the model. It describes the Subjective Expected Utility model of decision under uncertainty, and the Ellsberg paradox as an example of the Knight’s approach to...
In this paper we extend the model of Resolute Choice to a situation of interaction and compare it with the Sophisticated-subgame perfect equilibrium and the Myopic Choice models in terms of welfare implications. The framework adopted is a non-cooperative game in which two players with different preference orderings over outcomes move sequentially....
Aim of this work is to contribute to the discussion about the link between metacognitive abilities and overconfidence. In particular we want to empirically investigate the existence and the sign of the above relation. In the work we therefore elicit forecast evaluation: (1) using data from two sets of midterm exams and question-by-question evaluati...
Our experiment studies the impact of two types of relational goods on the voluntary contributions for the
production of a public good, i.e. acquaintance among the contributors and performance of a team work before
the experiment. Our results show that: (1) both team work and previous acquaintance increase the average
contribution to the public good...
This paper inquires experimentally whether competition has any impact on the individual disposition to contribute voluntarily to the provision of a public good. Participants perform a task and are remunerated according to two schemes, a non-competitive and a competitive one, then they play a standard public goods game. In the first scheme participa...

We use data on response times from a public goods experiment to test the hypothesis that cooperation is instinctive, under the assumption that the longer the time of the decision, the less instinctive the choice. Results seem to support the hypothesis that cooperation is instinctive, while defection is ‘rational’. Moreover, as the experiment is des...
Our experiment aims at studying the impact of two types of relational goods on the voluntary contributions to the production of a public good, i.e. acquaintance among the contributors and having performed a common work before the experiment. We implement two treatments with 128 participants from two different groups. In the first treatment the subj...
In this paper we examine the performance of theories of decision making under uncertainty/ambiguity from the perspective of their descriptive and predictive power, taking into account the relative parsimony of the various theories. To this end, we employ an innovative experimental design which enables us to reproduce ambiguity in the laboratory in...
Dynamically inconsistent decision makers have to decide, implicitly or explicitly, what to do about their dynamic inconsistency. Economic theorists have identified three possible responses – to act naively (thus ignoring the dynamic inconsistency), to act resolutely (not letting their inconsistency affect their behaviour) or to act sophisticatedly...
The purpose of this paper is that of extending the model of Resolute Choice (McClennen 1990) to a situation of interaction and comparing its performance with the Sophisticated-subgame perfect equilibrium model in an experiment. A non-cooperative game in which two players with different preference orderings over outcomes move sequentially is adopted...
There is a large theoretical literature in both economics and psychology on decision making under ambiguity (as distinct from risk) and many preference functionals proposed in this literature for describing behaviour in such contexts. However, the empirical literature is scarce and largely confined to testing between various proposed functionals. U...
In this paper the problem of inconsistent dynamic choice is discussed, as considered in the literature, both under certainty in the
context of changing preferences, and under risk and uncertainty in the case of preference orderings which violate expected utility
theory.
The problem of inconsistent choice in a dynamic decision situation has been ini...
