In a site-selection choice experiment various hypotheses are tested related to spatial heterogeneity in willingness to pay (WTP) for environmental improvements. Spatial heterogeneity is measured through distance-decay effects, substitute sites inside and outside the experiment’s choice set,...

We contrast the discovered preference hypothesis against the theory of coherent arbitrariness in a split-sample stated choice experiment on flood-risk exposure. A semiparametric local multinomial logit model is developed as an alternative to the Swait and Louviere (1993) test procedure...

The main objective is to assess preference heterogeneity related to the spatial distribution of water quality improvements throughout a river basin. In a choice experiment, the river basin’s hydrogeographical units and the levels of water quality improvement are included as attributes in the...
