“…Embedding is reduced in deliberation by providing sufficient time and multiple perspectives by which to consider questions of scope and tradeoff [12]. Deliberative groups can be especially useful when dealing with challenging welfare measures such as willingness to accept compensation, where discussion and deliberation can reduce strategic over-bidding and protest bidding [14,18,[32][33][34][35].…”

“…There is evidence that improved knowledge and information about the good or service in question meaningfully changes aggregate preferences-not just individual positions, but the aggregate distribution of preferences would be different on many issues if all respondents were better informed [5,9,11,12,14,18,22,29,35,36]. Traditional stated preference surveys give an overview of preferences as is; deliberation also offers the chance to examine preferences after a minimum threshold of knowledge is obtained.…”

“…Most notably, past deliberative valuation studies have had restricted sample sizes when compared to other stated preference methodologies, due to the high cost per participant and limited effectiveness of large deliberative groups. This has led to concerns about representation and the ability of deliberative valuation to reflect the preferences of the broader community [15][16][17][18][19]. The time investment required of participants in deliberation has also led to problematic sample compositions, with the systematic underrepresentation of a number of social and economic groups [19][20][21][22].…”
When compared with other stated preference valuation methodologies, deliberative valuation gives participants more time and information, potentially resulting in more valid and reliable estimations and higher participant confidence. However, it also has weaknesses, such as small sample sizes, lower participant diversity, and high costs. This paper proses a minimalist framework for deliberation that increases sample size and lowers the cost per participant through short, structured deliberative sessions and the use of deliberative sub-groups. A case study was conducted with 192 landholders in south-eastern Mexico, examining how participants’ perceptions of benefits from communal forest lands would impact their willingness to accept (WTA) comparatively lower payments to participate in a Payment for Ecosystem Services (PES) program. The results suggest that a majority of landholders would accept a lower payment level to participate in a PES program over a degradative alternative, with 45.5% of participants surveyed willing to accept a 45% reduction in payments to participate in the PES program. The minimalist framework had an impact on participants’ rate of acceptance, with a 13.8% increase in the percentage of participants willing to accept the PES offer post-deliberation. The impact on participant confidence was stronger, with a 31.2% increase in the percentage of participants expressing confidence in their choice after deliberations.

“…More recently studies are now explicitly focusing on the application of DMV techniques for the valuation of ecosystem services (e.g. Atkinson et al 2012;Balderas Torres et al 2012;Christie et al 2012), as the ecosystem services approach has become mainstream (exemplified in initiatives like the Millennium Ecosystem Assessment and The Economics of Ecosystems and Biodiversity -TEEB). This paper distinguishes from previous studies by examining DMV literature to assess how deliberative approaches combined with monetary valuation methods have been utilised to explicitly determine the value of ecosystem services.…”
It was found that DMV still faces large practical and theoretical challenges, most notably the lack of a theoretical base for the interpretation of the monetary values produced. Before these challenges are addressed it is early days to assess the usefulness of DMV for the valuation of ecosystem services.
“…In the final paper, Balderas Torres et al (2013) similarly relate contingent valuation of willingness to reduce carbon emissions at household level with a wide range of household attributes, including socio-economic conditions, environmental awareness, risk perception and ethical/citizenship attitudes. Their findings show differentiation of willingness to pay for conservation of the local La Primavera Biosphere Reserve in Guadalajara (Mexico) triggered by different levels of perceived co-benefits derived from the forest by respondents.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
