This paper obtains an additive representation for preferences over subsets of a finite set relaxing the two substantive axioms in Kreps (1979) flexibility theorem. The result implies that the lottery structure and assumptions ...

The combination of a strict labor legislation with daily and weekly time-dependent demand patterns has meant that transit companies tend to suffer significant inefficiencies; indeed, as more drivers than the minimum required ...

The harvester ant Pogonomyrmex mendozanus is endemic to the central Monte desert. In this region, extensive grazing reduces grass cover and seed abundance in the soil bank. In previous studies carried out in ungrazed areas, ...

Intuitionistic reciprocal preference relations constitute a flexible and simple representation of decision makers' preference on a set of alternative options, while at the same time allow to accommodate degrees of hesitation ...

Habitat degradation caused by cattle grazing may be a serious threat for seed-eating birds because the availability of beneficial seeds usually diminishes in grazed areas. Ecologically plastic species might, however, ...

We analyse the choice of mode in suburban corridors using nested logit specifications with revealed and stated preference data. The latter were obtained from a choice experiment between car and bus, which allowed for ...

Although noise levels in urban areas frequently surpass the designated norms the consequences on health are only beginning to be examined. A stated preference experiment is used to estimate the willingness-to-pay for ...
