Choice consistency and preference stability in test-retests of discrete choice experiment and open-ended willingness to pay elicitation formats

This study was funded by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) in Zürich.This study tests the temporal stability of preferences, choices and willingness to pay (WTP) values using both discrete choice experiment (DCE) and open-ended (OE) WTP elicitation formats. The same sample is surveyed three times over the course of two years using each time the same choice sets. Choice consistency is positively correlated with choice certainty and choice complexity. The impact of choice complexity fades away in time, most likely as a result of learning and preference refinement. Although the OE WTP values remain stable over a time period of 2 years as in previous stated preference studies, DCE based WTP measures differ significantly, suggesting their use in benefits transfer may be limited.Publisher PDFPeer reviewe

Public preferences and willingness to pay for forest disease control in the UK

Invasive pests and diseases in trees impose a range of costs on society related to reductions in timber values, impacts on recreational opportunities and effects on forest biodiversity. These costs need to be considered when assessing control options and developing public policy. We investigate the preferences and willingness to pay of the UK general public for a range of forest disease control measures using a choice experiment with a sample of 605 people. Respondents were relatively well informed about general tree disease-related issues, such as causes and general measures to minimise the risk of disease spread. They were less knowledgeable about specific tree diseases, with Dutch elm disease and chalara ash dieback being the most well known. We find that disease control programmes in publicly-owned forests and forests owned by charitable trusts are more likely to be supported by the public than equivalent control programmes in privately-owned and/or commercial forests. The nature of scientific uncertainty about diseases does not affect peoples’ preferences for disease control measures significantly. Higher respondent income, greater ex-ante knowledge about tree diseases, and more frequent visits to forests are correlated with greater willingness to support publicly-funded tree disease control programmes in forests. Better knowledge about tree diseases also improves the clarity of respondents’ choices. We find a negative sentiment against some disease control measures, such as clear felling of a forest, and chemical or biocide spraying. We conclude that there is significant public support for part-financing forest disease control policies in the UK, but that this is conditional on forest ownership and the type of control measures used

Incentivising participation and spatial coordination in payment for ecosystem service schemes: forest disease control programs in Finland

This paper considers the problem of designing PES-type contracts to encourage participation and spatial coordination amongst private forest owners in Finland. The aim of the policy is to increase efforts to mitigate risks from invasive forest pests and diseases. Such control actions yield spill-over benefits to other landowners and to wider society, meaning that the level of privately-optimal disease control is likely to be less than the socially-optimal level. The policy designer may wish to encourage spatial coordination in the uptake of such PES-type contracts, as spatial coordination delivers an increase in the effectiveness of control measures on disease risks. We conducted a choice experiment with private forest owners in Finland in October 2016. The study elicited the preferences of woodland owners with respect to the design of forest disease control contracts, and gauged their willingness to cooperate with neighbouring forest owners within the framework of such programs

Political and legal aspects of the information warfare

This article describes the technological features of information warfare and possible lawful mechanisms to counter information attacks. The aim of the article is to analyse the political and legal features of information warfare. The tactics of the aggressor state’s behaviour in a hybrid war was substantiated using the case of the information war between Russia and Ukraine. The channels of information dissemination, which are most often used for disintegration and disinformation purposes, were studied. Problematic issues of the domestic public space that most often appear in the perspective of disinformation attacks on the Internet are determined: the activities of the Armed Forces of Ukraine, cooperation between Ukraine and the EU, reforms in Ukrainian society, temporarily occupied territories and annexed Crimea, corruption in Ukraine. The tactics of confrontation between countries in the information space was analysed — attempts to establish their “security belt” from other actors in international relations and to maintain their own dominant influence in certain regions by spreading misinformation. Promising areas of further research will be the analysis of the peculiarities of the national legal systems’ development in order to counter misinformation in the context of the continuous development of democracy in the world

The Allure of the Illegal: Choice Modeling of Rhino Horn Demand in Vietnam

Using choice modeling, we explore willingness to pay for rhino horn among existing and potential future consumers in Vietnam. We find that wild-sourced horn, harvested humanely from the least rare species, is the most highly valued product. Furthermore, consumers are willing to pay less for rhino horn products under a scenario where international trade is legalized compared to the current situation of illegal trade. We discuss the potential implications of our findings on rhino poaching and international trade policy

Assessing the societal benefits of river restoration using the ecosystem services approach

This paper is a contribution from the EU seventh framework funded research project REFORM (Grant Agreement 282656).The success of river restoration was estimated using the ecosystem services approach. In eight pairs of restored–unrestored reaches and floodplains across Europe, we quantified provisioning (agricultural products, wood, reed for thatching, infiltrated drinking water), regulating (flooding and drainage, nutrient retention, carbon sequestration) and cultural (recreational hunting and fishing, kayaking, biodiversity conservation, appreciation of scenic landscapes) services for separate habitats within each reach, and summed these to annual economic value normalized per reach area. We used locally available data and literature, did surveys among inhabitants and visitors, and used a range of economic methods (market value, shadow price, replacement cost, avoided damage, willingness-to-pay survey, choice experiment) to provide final monetary service estimates. Total ecosystem service value was significantly increased in the restored reaches (difference 1400 ± 600 € ha−1 year−1; 2500 − 1100, p = 0.03, paired t test). Removal of one extreme case did not affect this outcome. We analysed the relation between services delivered and with floodplain and catchment characteristics after reducing these 23 variables to four principal components explaining 80% of the variance. Cultural and regulating services correlated positively with human population density, cattle density and agricultural N surplus in the catchment, but not with the fraction of arable land or forest, floodplain slope, mean river discharge or GDP. Our interpretation is that landscape appreciation and flood risk alleviation are a function of human population density, but not wealth, in areas where dairy farming is the prime form of agriculture.PostprintPeer reviewe

Clinical markers of immune disorders in the pathogenesis of Escherichia coli enteritis

Background. Escherichia coli enteritis is one of the most common causes of diarrhea in developed countries and is caused usually by pathogenic strains of Escherichia coli. Objectives. To investigate the role of reactive response of polymorphonuclear neutrophilic granulocytes (NG) of peripheral blood in the systemic inflammatory response mechanisms of acute Escherichia enterocolitis (AEC), depending on genes polymorphism of heat shock proteins (HSP) family 70-2 (HSP70-2, 1267A®G) and interleukin 10 (IL-10, C-592A). Material and methods. The genes polymorphism was analysed by PCR based method in 95 patients with AEC and 30 healthy individuals. Clinical markers of immune disorders were evaluated after hematological indices, based upon an extended general clinical blood analysis, using verified formulas. Results. The endogenous intoxication severity did not depend reliably on genotypes of IL-10 gene (rs1800872), however it was significantly 23.68% (р=0.043) higher in GG-genotype carriers of HSP70-2 gene (rs1061581). The reduction of cellular reactivity by 14.71-19.08% (р<0.01) did not depend on the analyzed genes genotypes. But general non-specific immune reactivity decreases 3.49-4.24 times (р<0.001) was deeper in GG-genotype carriers of HSP70-2 gene and AA-genotype carriers of IL-10 gene by 17.78% (р=0.009) and 12.37% (р=0.023) respectively. The immunologic resistance index was lower by 18.75% (р=0.024) in GG-genotype carriers than in patients with А allele. Conclusions. Hematological indices, based upon an extended general clinical blood analysis, are indicative and reliable non-specific clinical markers of immune disorders in case of AEC
