The Mas-Colell bargaining set is shown to contain the classical bargaining set for superadditive NTU games satisfying the nonlevelness condition. Without superadditivity this is no longer true, but in the TU case the containment still holds for the closure of the Mas-Colell bargaining set.

Economists have often attempted precise measurement of phenomena which involve vague predicates. Difficulties emerge in such attempts if vagueness is not explicitly acknowledged at the methodological level. In this paper, various accounts of vague concepts are used to think about the economics...

We present a technique to estimate the star-discrepancy of (t, m, s)-nets using generalized Haar function systems and apply this technique to obtain upper bounds for the star-discrepancy of special digital (t, m, s)-nets in base 2 and dimension s=2.

This paper studies by means of reciprocal fuzzy binary relations the aggregation of preferences when individuals show their preferences gradually. We have characterized neutral aggregation rules through functions from powers of the unit interval in the unit interval. Furthermore, we have...
