We present a new version of the overtaking criterion, which we call generalized time-invariant overtaking. The generalized time-invariant overtaking criterion (on the space of infinite utility streams) is defined by extending proliferating sequences of complete and transitive binary relations...

We examine who benefits when there is a strong leader in place, and those who benefit when a situation lacks a proper leader. There are fractious terrorist groups who seek to serve the same people in a common cause against a common enemy. The groups compete for rents obtained from the public by...

We develop an incomplete contract model to analyse the enlargement strategy of a club. An applicant is characterized by his wealth and the degree of conformity with the club standard. The club gains only from a fully reformed new member, but reform is costly. The club chooses between early...

I develop a model of group decision-making, in which a committee generates proposals and holds open discussions, but the ultimate decision is either taken by a leader (decision by authority) or by majority vote. Optimal communication processes are studied that combine both cheap talk statements...

In this paper, we evaluate the impact of Turkey's membership on EU voting. The aspects that we discuss are decision-making efficiency and the distribution of power in the EU's leading decision making body the Council of Ministers. We compare two alternative Council voting rules: those accepted...

The phenomenon of choice shifts in group decision-making is fairly ubiquitous in the social psychology literature. Faced with a choice between a ‘safe’ and ‘risky’ decision, group members appear to move to one extreme or the other, relative to the choices each member might have made...

People with a self-control problem often seek relief through social interactions rather than binding commitments. Thus, in self-help groups like Alcoholics Anonymous, Narcotics Anonymous etc, members are said to achieve better personal outcomes by mainly sharing their experiences. In other...

Each solution concept on a class of normal form games with a given outcome space can be regarded as a social choice correspondence. Here we present a general method of constructing compound solution concepts out of given ones by means of games of pretension.

The condorcet winner in an lection is the candidate who would be able to defeat all other candidates in a series pairwise elections. The Condorcet efficiency of a voting procedure is the conditional probability that it will elect the Condorcet winner, given that a Condorcet exists. The study...

This Paper analyses a hold-up problem in the EU enlargement process. EU-specific anticipatory investments of private firms lower the governments outside option. The EU takes advantage of the applicants' increased dependency and extracts more surpluses through entrance conditions that benefit it...
