By using the standard combining logics technique (D. M. Gabbay 1999) we define a generalization of von Wright’s preference logic (G. H. von Wright 1963) enabling to express, on an almost propositional level, the individual and the social preference relations simultaneously. In this context we...

This paper studies a class of judgment aggregation rules, to be called `scoring rules' after their famous counterpart in preference aggregation theory. A scoring rule delivers the collective judgments which reach the highest total `score' across the individuals, subject to the judgments having...

The contribution is to analyze why harmful lobbyism against the transition to market economy takes place and to recommand how this important barrier to economic growth can be eliminated.

A social choice correspondence called the Essential Set is studied with the help of an axiom called Cloning Consistency.

A social policy is a rule which assigns each possible set of endowments an allocation of these endowments among members of society. This paper assumes that individuals have preferences over private consumption and preferences over all possible social policies.

We illustrate by means of a dynamic research and development race that, while at some points in the race, social incentives and private incentives may coincide, at other points they may diverge-- too many researchers remain that race.

We consider abstract social systems of private property, made of n individuals endowed with non-paternalistic interdependent preferences, who interact through exchanges on competitive markets and Pareto-efficient lumpsum transfers. The transfers follow from a distributive liberal social contract...

In a framework of preferences over lotteries, we show that an axiom system consisting of weakened versions of Arrow's axioms has a unique solution. "Relative Utilitarianism" consists of first normalising individual von Neumann-Morgenstern utilities between 0 and 1 and then summing them. This...

We provide a characterization of selection correspondences in two-person exchange economies that can be core rationalized in the sens that there exists a preference profil with some standard properties that generates the observed choices as the set core elements of the economy for any given...
