We use subjects’ actions in modified dictator games to perform a within-subject classification of individuals into four different types of interdependent preferences: Selfish, Social Welfare maximizers, Inequity Averse and Competitive. We elicit beliefs about other subjects’ actions in the...

Patients with stage-I (very mild and mild) Alzheimer’s disease were asked to participate in a Dictator Game, a type of game in which a subject has to decide how to allocate a certain amount of money between himself and another person. The game enables the experimenter to examine the influence...

Does risk attitude (aversion or attraction) vary with the level of the income at risk? About half of our subjects chose to insure all levels, whereas another half chose instead not to insure low levels, but to insure high levels.

Many experiments have shown that human subjects do not necessarily behave in line with game theoretic assumptions and solution concepts. The reasons for this non-conformity are multiple. In this paper we study the argument whether a deviation from game theory is because subjects are rational,...

In an experimental standard Cournot Oligopoly we test the importance of models of behavior characterized by imitation of succesful behavior. We find that the players appear to the rather reluctant to imitate.

We test in the laboratory the potential of evolutionary dynamics as predictor of actual behavior. To this end, we propose an asymmetric game -which we interpret as a borrowerlender relation-, study its evolutionary dynamics in a random matching set-up, and tests its predictions. The model...

"Beauty-contest" is a game in which participants have to choose, typically, a number in [0,100], the winner being the person whose number is closest to a proportion of the average of all chosen numbers. We describe and analyze Beauty-contest experiments run in newspapers in UK, Spain, and...

We consider an oligopolistic market game, in which the players are competing firm in the same market of a homogeneous consumption good. The consumer side is represented by a fixed demand function. The firms decide how much to produce of a perishable consumption good, and they decide upon a...

Informal care is today the form of support most commonly used by those who need other people in order to carry out certain activities that are considered basic (eating, dressing, taking a shower, etc.), in Spain and in most other countries in the region. The possible labour opportunity costs...

Unemployment rates in developed countries have recently reached levels not seen in a generation, and workers of all ages are facing increasing probabilities of losing their jobs and considerable losses in accumulated assets. These events likely increase the reliance that most older workers will...
