“…one cannot at all levels of a particular good fully compensate an individual for a certain reduction of the good by an increase in another good (such as money). In a more recent paper (Amiran and Hagen, 2010), the authors extend the analysis of such bounded utility functions to another phenomenon often observed in the CV literature, the limited sensitivity to scope. Specifically, they show that one cannot, based on standard consumer theory, rule out arbitrarily small degrees of sensitivity to scope for this class of utility functions.…”

“…The existence of universal hypersubstitutability, implicit in functions such as the Cobb-Douglas, seems highly implausible. While it may appear that this property only has implications at extreme levels of consumption, it has been shown to have important implications in contexts where the changes in consumption quantities are not large [8] [9].…”

“…In what follows we make use of the formal definition of directionally bounded utility first proposed by Amiran and Hagen [9]. Consider a utility function ( ) , u q w that depends continuously on non-market and market goods whose consumption levels are ( )…”

“…comparing mean WTP for those who received 4.5% and 10% as their second WTP question). 25 Putting too much weight on the lack of external scope as a sign of unreliable data would be too simplistic, as there may be good reasons for not having higher WTP for the 10% plan compared to the 4.5% plan (Amiran and Hagen, 2010;Lindhjem, 2007). Marginal existence value may be diminishing (Rollins and Lyke 1998) or respondents may even feel that as long as a sufficient amount of biodiversity is preserved for the species not to be threatened anymore, it is good enough (Jacobsen et al, 2012).…”
