Modelling Outcome‐Related Risk in Choice Experiments

Klaus Glenk; Sergio Colombo

In this study, we introduce information on outcome‐related risk as an additional attribute in a choice model of preferences for a land‐based climate change mitigation project. We provide a comprehensive comparison of different model specifications arising from different behavioural assumptions about the way that respondents process information on outcome‐related risk within the choice task. We find significant differences between several specifications in terms of both model fit and WTP estimates. The behavioural assumptions made when choosing a particular model specification, and reasons that motivate them should be made explicit, and consequences of using different specifications should not be ignored.

Assessing economic preferences for biological diversity and ecosystem services at the Central Sulawesi rainforest margin — a choice experiment approach

Jan Barkmann; Klaus Glenk; Handian Handi; Leti Sundawati; Jan-Patrick Witte; Rainer Marggraf

Recognition of the importance of economically sound conservation strategies is one of the foundations of the Convention on Biological Diversity. Because of their exceptional contribution to global biological diversity, the conservation of the Central Sulawesi (Indonesia) rainforests is a particularly important case for a successful application of such strategies. One of the obstacles to the design and implementation of economically sound conservation strategies is the lack of knowledge on the economic value of non-market benefits generated by tropical forest ecosystems and the agricultural land use systems that replace them.

Using local knowledge to model asymmetric preference formation in willingness to pay for environmental services

Klaus Glenk

This paper describes an approach to account for asymmetric preference formation in discrete choice models used for environmental valuation. The paper draws on data from a case study on preferences for environmental change resulting from a hypothetical rural development and conservation programme in Indonesia. Local knowledge on the current state of the environment was used to define an individual-specific status quo that consistently frames changes in a range of environmental services as gains or losses matching the perceptions of the local population living in the vicinity of a National Park. I estimated choice models that included separate parameters for increases and decreases in attribute levels for the environmental services and derived the indicators of local willingness to pay (WTP) corresponding to the bidirectional changes relative to the individual-specific status quo option. I found clear evidence of an asymmetric response to increase and decrease in attribute levels relative to the status quo. Ignoring asymmetric preference formation can therefore result in biased estimates of WTP indicators and welfare measures of change in cases where the outcomes of environmental programmes can plausibly result in both an increase and a decrease relative to a reference option. Compared to a symmetrical modelling approach, the combination of simultaneously accounting for asymmetric preference formation and preference heterogeneity in the choice model yielded additional insights that may be used to inform the development of local strategies towards biodiversity conservation.

Social preferences for agricultural policy instruments: joint consideration of non-attendance to attributes and to alternatives in modelling discrete choice data

Sergio Colombo; Klaus Glenk

This paper uses the choice experiment method to analyse social preferences towards a set of agricultural policy instruments that are likely to play a key role in the post-2013 design of the EU Common Agricultural Policy. It contributes to the choice experiment literature by incorporating different attribute processing strategies into stated choice models. By comparing models that consider attribute non-attendance for individual choice tasks and for the whole sequence of choices, we demonstrate the impact of different ways of accounting for attribute non-attendance on model performance and preferences. In addition, we test whether ‘non-attendance to alternatives’, which describes the elimination of alternatives due to the presence of attribute levels deemed unacceptable to a respondent, is a relevant information processing strategy in a choice experiment context. The results clearly show that individuals allocate attention over a reduced array of information and jointly apply decision strategies that involve attribute non-attendance and non-attendance to alternatives. The joint consideration of these information processing strategies results in a significant improvement of model fit to data, and a better description of respondents’ preferences.

Protest Responses and Willingness to Accept: Ecosystem Services Providers’ Preferences towards Incentive-Based Schemes

Anastasio J. Villanueva; Klaus Glenk; Macario Rodríguez-Entrena

The identification and treatment of protest responses in stated preference surveys has long been subject to debate. We analyse protest responses while investigating ecosystem services providers’ preferences for incentive‐based schemes. We use a choice experiment for olive farmers’ preferences for agri‐environmental scheme participation in southern Spain. Our two main objectives are: first, to identify and discuss a range of possible motives for protest responses that emerge in a WTA context; second, we analyse the impact on WTA estimates of censoring serial non‐participation linked to protest or high compensation requirements (very high takers). Using a random parameter logit model in WTA space, we find that the inclusion or exclusion of serial non‐participants in the analysis can have a significant impact on marginal and total WTA estimates. Based on the findings, the paper makes recommendations on how to reduce the incidence of protest responses through survey design, regarding the identification of protesters as opposed to very high takers, and regarding the treatment of both groups of respondents for WTA estimation.

Prospects for Payments for Ecosystem Services in the Brazilian Pantanal: A Scenario Analysis

Christopher Schulz; Antonio A. R. Ioris; Julia Martin-Ortega; Klaus Glenk

The present study investigates the prospects for a large-scale implementation of Payments for Ecosystem Services (PES) schemes in the Brazilian Pantanal wetland. Despite increasing environmental threats associated with development pressures and the growing interest of public and private organizations, no PES schemes are currently in place in the Pantanal. Through an exploratory scenario analysis, this article determines the prospects for PES in the area. The findings suggest that a large-scale implementation is unlikely, as this would require much higher levels of environmental awareness among local decision makers and low substitution rates of ecosystem services by technology. Furthermore, strong socioeconomic inequality between inhabitants of the Pantanal lowlands and wealthy farmers of the neighboring uplands means that potential suppliers of ecosystem services would face very high opportunity costs to participate in PES schemes. The research findings are also relevant to other environmentally sensitive regions experiencing rapid economic growth and weak environmental regulation.

How to make complexity look simple? Conveying ecosystems restoration complexity for socio-economic research and public engagement

Julia Martin-Ortega; Klaus Glenk; Anja Byg; Asim Zia

Ecosystems degradation represents one of the major global challenges at the present time, threating people’s livelihoods and well-being worldwide. Ecosystem restoration therefore seems no longer an option, but an imperative. Restoration challenges are such that a dialogue has begun on the need to re-shape restoration as a science. A critical aspect of that reshaping process is the acceptance that restoration science and practice needs to be coupled with socio-economic research and public engagement. This inescapably means conveying complex ecosystem’s information in a way that is accessible to the wider public. In this paper we take up this challenge with the ultimate aim of contributing to making a step change in science’s contribution to ecosystems restoration practice. Using peatlands as a paradigmatically complex ecosystem, we put in place a transdisciplinary process to articulate a description of the processes and outcomes of restoration that can be understood widely by the public. We provide evidence of the usefulness of the process and tools in addressing four key challenges relevant to restoration of any complex ecosystem: (1) how to represent restoration outcomes; (2) how to establish a restoration reference; (3) how to cope with varying restoration time-lags and (4) how to define spatial units for restoration. This evidence includes the way the process resulted in the creation of materials that are now being used by restoration practitioners for communication with the public and in other research contexts. Our main contribution is of an epistemological nature: while ecosystem services-based approaches have enhanced the integration of academic disciplines and non-specialist knowledge, this has so far only followed one direction (from the biophysical underpinning to the description of ecosystem services and their appreciation by the public). We propose that it is the mix of approaches and epistemological directions (including from the public to the biophysical parameters) what will make a definitive contribution to restoration practice.

A behavioural economics analysis of the impact of information and knowledge on CO2 capture and storage acceptance in the European Union

Luiza Toma; Andrew P. Barnes; Cesar Revoredo-Giha; Viktoria Tsitsoni; Klaus Glenk

Abstract The paper analyses the impact that European Union citizens’ access to information on climate change has on their awareness of carbon capture and storage (CCS), perceived risks and benefits of using CCS and stated choice of preferred CCS options. We use a Eurobarometer dataset about awareness/acceptance of CCS and run structural equation models (SEM) for twelve EU countries with an average sample size of 1,100 observations per country. Results between the different countries are comparable and, alongside other determinants, access to information sources will significantly impact CCS awareness, perceived risk and benefits of CCS and preferences towards options of CCS.

From welcome culture to welcome limits? Uncovering preference changes over time for sheltering refugees in Germany

Ulf Liebe; Jürgen Meyerhoff; Maarten Kroesen; Caspar G. Chorus; Klaus Glenk

Europe recently experienced a large influx of refugees, spurring much public debate about the admission and integration of refugees and migrants into society. Previous research based on cross-sectional data found that European citizens generally favour asylum seekers with high employability, severe vulnerabilities, and Christians over Muslims. These preferences and attitudes were found to be homogeneous across countries and socio-demographic groups. Here, we do not study the general acceptance of asylum seekers, but the acceptance of refugee and migrant homes in citizens’ vicinity and how it changes over time. Based on a repeated stated choice experiment on preferences for refugee and migrant homes, we show that the initially promoted “welcome culture” towards refugees in Germany was not reflected in the views of a majority of a sample of German citizens who rather disapproved refugee homes in their vicinity. Their preferences have not changed between November 2015, the peak of “welcome culture,” and November 2016, after political debates, media reporting and public discourse had shifted towards limiting admission of immigrants. A minority of one fifth of the sample population, who were initially rather approving of refugee and migrant homes being established in their vicinity, were more likely to change their preferences towards a rather disapproving position in 2016. Experience of contact with refugees and migrants, higher education, and general pro-immigration attitudes explain acceptance of refugee and migrant homes as well as preference stability over time. Country of origin and religion of refugees and migrants are considered less important than decent housing conditions and whether refugee and migrants arrive as families or single persons. In this respect our results highlight the importance of humanitarian aspects of sheltering and integration of refugees and other migrants into society.

The economics of peatland restoration

Klaus Glenk; Julia Martin-Ortega

ABSTRACT Restoration offers opportunities for securing and enhancing critical ecosystem services provided by peatlands, such as carbon storage, water retention and water quality, and support for biodiversity and wildlife. A comprehensive valuation encompassing the relevant public benefits of restoration and how these compare with it is lacking to date, leaving policy makers with little guidance with respect to the economic efficiency of restoring this climate-critical ecosystem. Using Scotland as a case study, this paper quantifies the non-market benefits of changes in peatland ecological condition associated with changes in ecosystem service provision and depending on the location of restoration efforts. Benefits on a per hectare basis are compared to varying capital and recurrent cost in a net present value space, providing a benchmark to be used in decision making on investments into peatland restoration. The findings suggest that peatland restoration is likely to be welfare enhancing. Benefits also exceed cost in appraisals of previous and future public investments into peatland restoration. The results thus strengthen the economic rationale for climate change mitigation through improved peatland management.
