Sensitivity to scope in nonmarket valuation refers to the property that people are willing to pay more for a higher quality or quantity of a nonmarket public good. Establishing significant scope sensitivity has been an important check of validity and a point of contention for decades in stated...

Using a choice experiment, this paper investigates how Swedish citizens value three environmental quality objectives. In addition, a follow-up question is used to investigate whether respondents ignored any attributes when responding. The resulting information is used in the model estimation by...

This paper examines the application of quasi-experimental methods in environmental economics. We begin with two observations: (i) standard quasi-experimental methods, first applied in other microeconomic fields, typically assume unit-level treatments that do not spill over across units; (ii)...

Information provided in valuation surveys has been shown to affect stated preferences, which in turn may matter for the validity and reliability of survey-based value estimates. Although such information effects are widely documented, the reasons underlying the effects are less established. We...

How does a choice experiment (CE) model derived under standard preference axioms perform for respondents with incomplete preferences?[...]

Using a choice experiment, this paper investigates how Swedish citizens value three environmental quality objectives. In addition, a follow-up question is used to investigate whether respondents ignored any attributes when responding. The resulting information is used in the model estimation by...

We investigate whether Swedish Environmental Protection Agency (EPA) administrator recommendations regarding improvements in environmental quality differ from citizen preferences. The scope and significance of the possible difference are assessed by conducting identical choice experiments on a...
