Publication Out of sight, not out of mind:(2024) Henríquez, Makarena; Vásquez Lavín, Felipe; Barrientos, Manuel; Ponce, Roberto D.; Lara, Antonio; Flores-Benner, Gabriela; Riquelme, CarlosAccording to the latest global assessment report on biodiversity and ecosystem services, nature and biodiversity have experienced a global decline, making the development of conservation policies urgent. Herein, we used a contingent valuation survey to estimate the economic value of a reintroduction program for the huemul (Hippocamelus bisulcus), an endangered charismatic species in Chile. Our novel approach exploits changes in the access to the site to disentangle nonuse value from use value. We use parametric and nonparametric models to estimate the willingness to pay for the program. Our findings consistently indicate that the conservation of the huemul is valued more when tourist access is restricted, as opposed to allowing visitors access to reintroduction areas. We also analyze the sensitivity of this main finding to different cut-off points of a certainty scale, showing that the results are robust. We hypothesize that people are willing to pay a “premium” to keep the conservation site “out of sight” from tourist activities. This could also be related to the belief that a reintroduction program would be more effective if access was not allowed. A cost-benefit analysis using the most conservative assumptions suggests that social benefit significantly outperforms cost.Publication Economic valuation of Harmful Algal Blooms (HAB):(2024) Carias, José; Vásquez Lavín, Felipe; Barrientos, Manuel; Ponce, Roberto D.; Gelcich, StefanThis paper presents a literature review on the economic valuation of Harmful Algal Bloom (HAB) impacts, identifying methodological challenges, policy implications, and gaps. Unlike previous literature reviews, we are particularly interested in determining whether the economic valuations of HABs have included a policy analysis. Our paper provides a conceptual framework that allows us to evaluate whether applications of economic studies of HABs are consistent with a well-defined economic welfare analysis. It links methodologies and techniques with welfare measures, data types, and econometric methods. Based on this literature review, we present an example of economic valuation that closes the gap between policy analysis and valuation methodology. We use a stated preferences study to estimate a “seafood price premium” to create a fund to support monitoring systems and for damage compensation to producers in the presence of HABs. Results show that most economic studies on HAB valuation do not consider any cost-benefit analysis of a defined policy intervention. The predominant economic valuation methodology uses market information to estimate a proxy for welfare measure of the impact of HABs (loss revenue, sales, exports). Moreover, nonuse and indirect use values are ignored in the literature, while stated preference methodologies are underrepresented. Finally, results from 1293 surveys found that people are willing to pay an increase in the price of mussels to support a policy that informs on HAB. However, the lack of institutional trust affects the probability of paying negatively.
