The role of social norms on conservation programmes in shellfish fisheries
Alló, M., Loureiro, M.L., (2017). "The role of social norms on conservation programs in shellfish fisheries", Marine Policy 84134-141.
Abstract
Ostrom (1990) has argued that in collective action problems, social factors are crucial in order to promote conservation. A survey instrument among shellfish gatherers has been used to analyse their preferences with respect to a proposed conservation management programme, assessing the effect of co-management initiatives and the impact of social norms on extraction. Results show that shellfish gatherers working in a Marine Protected Area (MPA) behave more conservatively with respect to their counterparts in terms of their current extraction patterns, promoting species conservation. With regards to social norms, expected believes about the fulfilment of the current extraction regulation in their network, allow for the acceptance of restrictions imposed by the conservation management plan without decreasing the shellfish gatherers’ utility in any significant way.
The Economics of Oil Spills
Loureiro, ML., Alló, M., (2017). "The economics of oil spills". Oxford Research Encyclopedia, DOI: 10.1093/acrefore/9780199389414.013.501
Abstract
Vessel oil spills are very serious natural hazards that have affected coasts worldwide for many decades. Although oil spills from tankers are highly publicized, very little is known about the role played by the incentives and regulatory instruments in place to prevent them. In order to shed some light on these issues, data were collected worldwide on large oil spills from multiple databases, starting in the 1970s, and merged with other socioeconomic records. A crucial concern is that that large oil spills have been undercompensated over time with respect to the damages caused. A meta-analysis was estimated in order to assess relevant factors affecting the damage claimed in oil spills and the compensations received by the affected parties. Meta-regression results show that the legislation applied (strict unlimited liability versus limited liability) played a crucial role in both the amount claimed and the final compensation received. Also, time-trend variables are shown as determining factors for both the damages and claims that are finally paid. To correct the large gap between damage claimed and compensation scenarios, it is recommended to strengthen compensation funds, while carrying out more comprehensive assessment studies which apply valuation methods comparable with those proposed by green capital initiatives for marine ecosystem services, and which could be used successfully during the litigation process.
The impact of offshore wind farms on beach recreation demand: Policy intake from an economic study on the Catalan coast
Voltaire, L, Loureiro, Maria L., C. Knudsen, PALD Nunes, (2017). "The impact of offshore wind farms on beach recreation demand: Policy intake from an economic study on the Catalan coast, Martine Policy", 81, 116-123.
Abstract
Offshore wind energy development can have major economic implications because of the potential impact on coastal recreation demand – particularly for countries that are characterised by high offshore wind power potential while also being popular tourist destinations. In this context, the impact of offshore wind farm projects on beach recreation demand in Catalonia (Spain) during the 2012 summer season was examined. A combined revealed and stated preference approach, which allows joint modelling of actual and hypothetical demands, was applied. The results demonstrate a significant welfare loss up to €203 million per season. The results further show that the installation of a wind farm mainly will cause a shift in trips to Catalan beaches without wind farms, which implies that the estimated negative economic impacts will occur mostly in areas where wind farms are located. From a political economy point of view, this may call for the design and implementation of re-distributive instruments to offset the negative impacts caused by wind farms.
Ecosystem Services and REDD: Estimating the Benefits of Non-Carbon Services in Worldwide Forests
Ojea, E. M. Loureiro, M. Alló, M. Barrio. 2016. “Ecosystem Services and REDD: Estimating the Benefits of Non-Carbon Services in Worldwide Forests” World Development, doi:10.1016/j.worlddev.2015.10.002
Abstract
Forest ecosystems are playing an increasingly important role in climate change mitigation through programs on Reducing Emissions from Deforestation and Forest Degradation (REDD), which targets carbon sequestration. However, decades of environmental valuation studies evidence the economic benefits of other forest ecosystem services different than carbon, and there is no evidence on how these economic benefits differ in countries where REDD is to be implemented. To respond to this question, we conduct a global meta-analysis of forest primary studies published over the past 30 years in which we estimate the economic benefits related to different forest ecosystem services in targeted REDD countries, and discuss the implications of considering these economic figures in REDD decision making. A systematic review of the scientific literature leads to the selection of 52 original studies to conduct a meta-analysis on 205 observations. We obtain that the economic benefits of forest ecosystem services in REDD countries are always greater than in other countries, and provide economic ranges of services to serve as a reference to REDD decision making in relation to co-benefits and opportunity costs. The results have implications for future avoided deforestation programs, which should take co-benefits into account in order to better articulate payments for ecosystems and create proper incentives for forest conservation and sustain local livelihoods.
Economic valuation of climate‐change‐induced vinery landscape impacts on tourism flows in Tuscany
Nunes, P. A., & Loureiro, M. L. (2016). "Economic valuation of climate‐change‐induced vinery landscape impacts on tourism flows in Tuscany". Agricultural Economics, 47(4), 365-374.
Abstract
It is widely acknowledged that landscape features can play a major role in determining tourism demand. The present article assesses the impact of vinery landscape and high‐quality wine production on regional tourism flows in Tuscany, an important tourist region in Italy and renowned for its enchanting countryside. Thus, vinery landscape and high‐quality wine production have been included as explanatory variables in our model for tourism flows. This model has been estimated for both international and domestic markets for the whole region of Tuscany. Estimation results confirm that land areas devoted to the production of these superb Tuscan wines, in the particular case of Siena including the Brunello di Montalcino, play an important role in explaining international tourism flows. In this context, we estimate climate‐change‐induced impacts on vinery landscape and quality wines in the tourism sector. These are estimated to cause a loss in the tourism revenues of nearly 15 and 20 million Euros a year, respectively, for 2020 and 2050, for the Tuscany region. Such losses are quite significant, and reiterate the urgency to identify and implement adequate policy options so as to moderate such land use changes, and respective negative welfare impacts.
The incidence of calorie labeling on fast food choices: A comparison between stated preferences and actual choices
Loureiro, M. L., & Rahmani, D. (2016). "The incidence of calorie labeling on fast food choices: A comparison between stated preferences and actual choices". Economics & Human Biology, 22, 82-93.
Abstract
In order to test the effect of calorie information on fast food choices, we conducted a questionnaire employing two types of stated preferences methods (the best-worst-scaling and intentional questions) and a follow-up randomized field experiment in a sample of 119 participants. This combined approach allowed us to test the internal validity of preferences for fast food meals across elicitation scenarios. The results showed that calorie information reduces the probability of selecting high calorie meals only in the questionnaire, while it did not have any significant impact on actual purchasing behavior in the field experiment. Thus, the findings show that there is a clear difference between the role of calorie information on immediate stated preference choices, and the relatively low level of responsiveness in real choices in a restaurant. We believe that the current results are quite suggestive, indicating the limits of predicting actual fast food behavior, and may open the way to using data sources that combine stated methods with field experiments.
Evaluating the fulfillment of the principles of collective action in practice: A case study from Galicia (NW Spain)
Alló, M., & Loureiro, M. L. (2016). "Evaluating the fulfillment of the principles of collective action in practice: a case study from Galicia (NW Spain)". Forest policy and economics, 73, 1-9.
Abstract
We analyze the type of communal forest owners' management practices through a survey in Northern Spain. In particular, we test whether the Principles of Collective Action (PCA) postulated by Ostrom (1990) are being followed in a sample of communal forests. Second, we study whether such principles derive in better forest management practices and conservation outcomes. Our results show that PCA are not perfectly fulfilled in our sample, showing a clear room for improvement. However, we have also found that in areas where their application is more predominant, forest owners have better management practices. Specifically, we have found a negative relationship between the fulfillment of PCA and the number of forest fires in our sample, while considering other socio-economic and control variables.
Ecosystem services values in Spain: A meta-analysis
Quintas-Soriano, C., Martín-López, B., Santos-Martín, F., Loureiro, M., Montes, C., Benayas, J., & García-Llorente, M. (2016). "Ecosystem services values in Spain: A meta-analysis". Environmental Science & Policy, 55, 186-195.
Abstract
We analyzed the state of the art in research on the economic valuation of ecosystem services in Spain. A review of 150 publications was conducted and included 649 economic value estimates. The results showed an increase in the number of scientific studies on the economic valuation of ecosystem services and a dissimilar distribution across regions. Cultural ecosystem services received the most attention, and coastal systems and forested areas were the most studied ecosystem types. We found differences in the economic value estimates among categories of services and among economic valuation methods, with provisioning services and market-based methods as those that elicited the highest economic values, respectively. Our results provide an overview of past and current economic valuation studies in Spain. In addition the results depict patterns that help in understanding the effects of different factors on economic value estimates and in providing insights for future research on ecosystem services assessment in Spain. We conclude that although economic assessments remain important in scientific and policy forums, we should also recognize additional approaches that are able to incorporate the plurality of values attached to ecosystem services.
Economic impacts of marine ecological change: Review and recent contributions of the VECTORS project on European marine waters
Groeneveld, R. A., Bartelings, H., Börger, T., Bosello, F., Buisman, E., Delpiazzo, E., ... & Loureiro, M. (2016). "Economic impacts of marine ecological change: review and recent contributions of the VECTORS project on European marine waters". Estuarine, Coastal and Shelf Science, 30, 1e12.
Abstract
Marine ecological change is likely to have serious potential economic consequences for coastal economies all over the world. This article reviews the current literature on the economic impacts of marine ecological change, as well as a number of recent contributions to this literature carried out under the VECTORS project. We focus on three main types of change, namely invasive alien species; outbreakforming species, such as jellyfish and toxic algae; and gradual changes in species distribution and productivity. The case studies available in the literature demonstrate that the impacts of invasions and outbreaks on fisheries, aquaculture, and tourism can potentially amount to several tens of millions of dollars each year in some regions. Moreover, stated preference studies suggest a substantial impact on coastal tourism and non-use values that is likely not visible in case studies of specific outbreak events. Climate-driven gradual changes in distribution and productivity of commercial fish stocks will have an impact on fisheries, although these impacts are likely to be overshadowed by much larger changes in prices of seafood and fuel.
Choice-Based Recommender Systems
Saavedra, P., Barreiro, P., Duran, R., Crujeiras, R., Loureiro, M., & Vila, E. S. (2016). "Choice-Based Recommender Systems". In RecTour@ RecSys (pp. 38-46).
Abstract
Choice-based models are proposed to overcome some of the limitations found in traditional rating-based strategies. The new approach is grounded on decision-making paradigms, such as choice and utility theories. Specifically, random utility models were applied in a recommendation problem. Prediction accuracy was compared with state-of-art ratingbased algorithms in a gastronomy dataset. The results show the superior performance of choice-based models, which may suggest that real choices could bring more predictive power than ratings
