The paper deals with combinatorial and stochastic structures of cubical token systems. A cubical token system is an instance of a token system, which in turn is an instance of a t...
This paper analyzes a two-alternative voting model with the distinctive feature that voters have preferences over the support that each alternative receives, and not only over the...
We present the first polynomial-time algorithm for computing the minimal covering set of a (weak) tournament. The algorithm draws upon a linear programming formulation of a subset...
Maximal elements of a binary relation on compact subsets of a metric space define a choice function. An infinite extension of transitivity is necessary and sufficient for such a c...
This paper considers the licensing of a quality-improving innovation. We analyze a duopoly model with heterogeneous firms and consumers. Firms compete in prices and face logit dem...
Topological separability is crucial for the utility representation of a complete preference relation. When preferences are incomplete, this axiom has suitably de...ned counterpart...
