Socially desirable responding (SDR) is an often-reported source of bias in survey interviews. It describes the tendency of a respondent to answer in a way that is socially desirable rather than to answer truthfully. This response bias also threatens the reliability and validity of survey-based environmental valuation techniques such as the Contingent Valuation Method (CVM). Therefore, the study deals with the assessment of the conditions for the occurrence of SDR in CVM interviews. A behavioral model is devised to take into account a set of factors triggering SDR responses. The impact of these factors of SDR on willingness to pay (WTP) responses is tested. The results reveal that the relevant factors do not affect WTP statements simultaneously but rather influence them in an independent manner. These findings can improve future CVM studies by identifying respondents who are prone to be influenced by SDR.

The provision of environmental goods by government creates social benefits which might vary between citizen groups with different cultural and ethnic backgrounds. These differences as well as the overall extent of benefits should be analysed before the implementation of public projects in order to consider not only the efficiency aspects of such a project but also its distributional effects. In Southwest China we are facing a rapid deforestation for the development of rubber cultivation and at the same time find an ethnically highly diverse population. This Contingent Valuation study tries to assess the short-term and long-term benefits accruing from a public reforestation programme in Xishuangbanna and their distribution among different ethnic groups living in that region. The results show that different ethnic groups value short-term and future benefits of reforestation differently and that these differences can be explained by the different cultural and historical backgrounds of these ethnic groups.

Abstract
To assess preferences for measures that strengthen security and defense as a public good, discrete choice experiments are a promising approach. For Germany, such a survey-based experiment reveals a strong preference for the installation of a European air defense system, but also for an increase in the troop size of the German military by 25% as well as the creation of a European army. For these changes, there is an aggregate willingness to pay of approximately 11.5 billion euros. Approval and willingness to pay vary by party preference. However, the reintroduction of compulsory military service is overwhelmingly rejected.

Article 8.1 (c) of the Directive calls for 'an economic and social analysis of the use of those waters and of the cost of degradation of the marine environment'. The MSFD is 'informed' by the Ecosystem Approach to management, with GES interpreted in terms of ecosystem functioning and services provision. Implementation of the Ecosystem Approach is expected to be by adaptive management policy and practice. The initial socio-economic assessment was made by maritime EU Member States between 2011 and 2012, with future updates to be made on a regular basis. For the majority of Member States, this assessment has led to an exercise combining an analysis of maritime activities both at national and coastal zone scales, and an analysis of the non-market value of marine waters. In this paper we examine the approaches taken in more detail, outline the main challenges facing the Member States in assessing the economic value of achieving GES as outlined in the Directive and make recommendations for the theoretically sound and practically useful completion of the required follow-up economic assessments specified in the MSFD. ; Publisher PDF ; Peer reviewed

Melanie Austen and Stefanie Broszeit are partially funded by the Marine Ecosystems Research Programme, Natural Environment Research Council (NERC) and Department for Environment, Food and Rural Affairs (DEFRA) (grant number NE/L003279/1). ; The EU Marine Strategy Framework Directive (MSFD) requires Member States to assess the costs and benefits of Programmes of Measures (PoMs) put in place to ensure that European marine waters achieve Good Environmental Status by 2020. An interdisciplinary approach is needed to carry out such an assessment whereby economic analysis is used to evaluate the outputs from ecological analysis that determines the expected effects of such management measures. This paper applies and tests an existing six-step approach to assess costs and benefits of management measures with potential to support the overall goal of the MSFD and discusses a range of ecological and economic analytical tools applicable to this task. Environmental cost-benefit analyses are considered for selected PoMs in three European case studies: Baltic Sea (Finland), East Coast Marine Plan area (UK) and the Bay of Biscay (Spain). These contrasting case studies are used to investigate the application of environmental cost-benefit analysis including the challenges, opportunities and lessons learnt from using this approach. This paper demonstrates that there are opportunities in applying the six-step environmental cost-benefit analysis framework presented to assess the impact of PoMs. However, given demonstrated limitations of knowledge and data availability, application of other economic techniques should also be considered (although not applied here) to complement the more formal environmental cost-benefit analysis approach. ; Publisher PDF ; Peer reviewed
