This article uses an explorative case study of the smart card industry where 'coopetition' is to be found. We show that the nature of interaction between smart card actors, dealing with industry and market conditions that create a very complex competitive landscape, constitutes a mix of...

Based on a social network analysis, as a methodology that can be used to analyze the relationships among people, as well as a proprietary database built by ourselves on inter-firm agreements formed in the smart card industry, this paper analyses the role and the influence of particular firms on...

We run a public good experiment with four different treatments. The payoff function is chosen such that the Nash equilibrium (NE) and the collective optimum (CO) are both in the interior of the strategy space. We try to test the effect of varying the level of the collective optimum, which...

We experiment a new mechanism for the provision of a discrete public good: in a fixed period individuals can contribute several times; at any moment they can see the total amount collected; at the end of the period, the public good is provided if the amount covers the cost. We find that the...

Our aim is to see whether the general result of a decreasing over contribution over time in a public goods game is still available at the group and at the individual levels. We find that individuals are heterogeneous and that they interact differently.

Generally, with a standard linear public goods game, one observes at the aggregate level that contributions lay between the Nash equilibrium and the social optimum and decrease over time with an end-effect.Our purpose is to see whether these general aggregate results remain available at the...

Nous présentons dans ce papier une modélisation du seuil critique de préférence pour la collusion dans un duopole mixte/privé en fonction du tarif d'interconnexion et de son coût marginal, dans un régime de concurrence à la Cournot. L'objectif consiste à comparer la préférence pour la...

In this paper, we propose to compare different partial transparency regimes in order to determine the optimal diessemination policy by the central bank, using an experimental approach. A treatment dedicated to the benchmark situation (where information is fully released) is also available. Our...

We try in this paper to characterize the state of mobile phone market in Tunisia. Our study is based on a survey of foreign experience (Europe) in detecting collusive behavior and a comparison of the critical threshold of collusion between operators in developing countries like Tunisia. The...
