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.

We experiment a mechanism for the provision of a discrete public good where individuals are allowed to upwards their contribution during a fixed time interval. Experimental evidence shows that subjects increase their contributions in order to finance the cost of the good. The public good is...

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...

The work undertook is located between Public Economic Theory and Experimental Economics. The object of the thesis consists in analysing the aggregate behavior and the individual heterogeneity in a voluntary contribution game.

This paper analyzes the relevance of the inflation targeting (IT) policy in achieving its primary goal of medium-term price stability. Contrary to previous studies, we propose, in this work, a new approach; an intermediate approach that consists in conducting a time-series analysis (employed in...

We test in the laboratory how entrepreneurs' skill perceptions influence the design of financing and advising contracts. Our theoretical framework proposes that self-confident entrepreneurs prefer issuing debt whereas low self-confident ones prefer equity which induces strong investor...

The European Central Bank (ECB) will offer to banks in 2013 an european shared platform for securities settlement, named TARGET 2 Securities (T2S), in order to open the national financial markets. The financial crisis did not change the ECB agenda. This paper develops a spatial competition model...

We present a Cournot model that compares the critical threshold of collusion in Duopoly and Oligopoly Markets where the actors are private, mixed or public. We assume that the incentive critical threshold for collusion depends on the interconnection fees. The different threshold values...
