We test an assortative mechanism whereby groups are formed endogenously, through the use of voting. Once formed, groups play a public-goods game, where the social value of an incremental contribution to the group account increases with the size of the group. Societies of nine people are...

The paper presents three different reconstructions of the 1980s boom of game theory and its rise to the present status of indispensable tool-box for modern economics. The first story focuses on the Nash refinements literature and on the development of Bayesian games. The second emphasizes the...

This is a contribution to the Journal Symposium on Douglass North's book on Understanding the Process of Economic Change by Structural Change and Economic Dynamics. It tries to understand his dynamic theory as that of the belief-institution co-evolution process and applies contributions of...

At age 17, Adam Smith accepted a Snell Fellowship to Oxford, agreeing to be ordained as a minister of the Church of England. Smith did not fulfill this obligation. Instead, Oxford officials agreed to allow him to transfer from the Ordination to the civil law tract; and, later, to leave Oxford...

Game theory is a branch of social sciences that formalizes decision-making in situations where two or more individuals or groups interact, possibly having conflicting interests. In Ortmann & Walraevens (2022) we have reconstructed Smith’s ways of thinking about the social world by analyzing...

In this paper I examine the relationship between Pareto-optimality and group size in linear public goods games or experiments. In particular, I use the standard setting of homogeneous linear public goods experiments and apply a recently developed tool to identify all Pareto-optimal allocations...

During the last three decades the ascent of behavioral economics clearly helped to bring down artificial disciplinary boundaries between psychology and economics. Noting that behavioral economics seems still under the spell of the rational choice tradition and, indirectly, of behaviorism we...

We reformulate the Humean farmer game on the basis of random assignment of advantage and the cost e of helping in another’s harvest. The result is a game that is a coordination game if e < ½ or a dominant strategy Prisoner’s Dilemma Game if e > ½ which allows a joint treatment of the two interpretations of the Humean farmer game. We employ two...</½>

Nash is famous for many inventions, but it is less known that he, simultaneously with Marschak, also was the first to axiomatize expected utility for risk. In particular, these authors were the first to state the independence condition, a condition that should have been but was not stated by von...
