Conservation investments are increasingly evaluated on the basis of their return on investment (ROI). Conservation ROI analysis quantitatively measures the costs, benefits, and risks of investments so conservancies can rank or prioritize them. This paper surveys the existing conservation ROI and...

This study assesses the potential cost-effectiveness of incentive payment programs relative to traditional top-down regulatory programs for biological conservation. We develop site-level estimates of the opportunity cost and the nonmonetized biological benefits of protecting biodiversity...

This study examines the spatial nature of optimal bioinvasion control. We develop a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal spatial-dynamic control strategies. We find that the optimal...

Energy generated from land-based wind power is expected to play a crucial role in the decarbonisation of the economy. With the looming biodiversity and nature crises, spatial allocation of wind power cannot, however, any longer be considered solely a trade-off against local disamenity costs....

On the one hand, wind power production is necessary for decarbonizing the electricity sector. On the other hand, we risk replacing one environmental problem with other environmental problems, that is, stopping climate change in exchange with increased loss of pristine land and biodiversity. The...

Data from a farm survey and choice experiment are used to value the benefits of Bt cotton in Pakistan. Unlike previous research on the economic impacts of Bt, which mostly concentrated on financial benefits in terms of gross margins, we also quantify and monetize positive externalities...

Norway is considering a national afforestation program for greenhouse gas (GHG) sequestration on recently abandoned semi-natural pastureland. However, the program may have negative impacts on landscape aesthetics and biodiversity. We conducted a national choice experiment survey to estimate...

Despite a large stated-preference literature on wind power externalities, few SP studies employ a case-control approach to examine whether people's acceptance of new wind power developments increases or decreases with exposure to and familiarity with wind turbines. Furthermore, the existing...

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...

Altruistic preferences of various forms may cause difficulties in welfare economics. In the valuation of public goods, such preferences are believed to help explain the substantial non-use values found in many stated preference (SP) valuation surveys. However, studies analysing the effect of...
