Stated preference surveys often give minimal attention to distinctions between intermediate and final ecosystem services, leading to the potential for welfare estimates that overlook, misrepresent or double count associated values. This paper illustrates potential mechanisms through which...

Stated preference surveys often provide ambiguous descriptions of ecological commodities, yielding welfare estimates that have unclear interpretations and cannot be linked to measurable outcomes. This paper proposes guidelines to promote ecological content validity in survey scenarios and...

Stated preference analyses often impose strong assumptions regarding spatial welfare distributions that can influence the validity of welfare analysis and aggregation. These include spatial homogeneity and continuous distance decay. Global assumptions such as these are increasingly questioned by...
