Tiivistelmä: | This paper employs a split-sample Contingent Valuation (CV) (hereafter for 'valuation' as: val.) design to investigate the potential for such ordering effects on stated willingness to pay for nested goods. In one 'top-down' design, values (here as: vals.) are first elicited for protecting the 'whole' of an endangered area after which vals. for a 'part' sub-area are elicited. A second 'bottom-up' treatment reverses the order of val. tasks with the 'part' scheme valued prior to the 'whole'. Results show that 'whole' and 'part' val. responses are logically ordered and determined by a consistent set of factors irrespective of question order. |
