英文摘要：
Coastal erosion is a global and pervasive phenomenon that predicates a need for a strategic approach to the future management of coastal values and assets (both built and natural), should we invest in protective structures like seawalls that aim to preserve specific coastal features, or allow natural coastline retreat to preserve sandy beaches and other coastal ecosystems. Determining the most suitable management approach in a specific context requires a better understanding of the full suite of economic values the populations holds for coastal assets, including non-market values. In this study, we characterise New South Wales residents willingness to pay to maintain sandy beaches (width and length). We use an innovative application of a Latent Class Binary Logit model to deal with Yea-sayers and Nay-sayers, as well as revealing the latent heterogeneity among sample members. We find that 65% of the population would be willing to pay some amount of levy, dependent on the policy setting. In most cases, there is no effect of degree of beach deterioration characterised as loss of width and length of sandy beaches of between 5% and 100% on respondents willingness to pay for a management levy. This suggests that respondents who agreed to pay a management levy were motivated to preserve sandy beaches in their current state irrespective of the severity of sand loss likely to occur as a result of coastal erosion. Willingness to pay also varies according to beach type (amongst Iconic, Main, Bay and Surf beaches) a finding that can assist with spatial prioritisation of coastal management. Not recognizing the presence of nay-sayers in the data or recognizing them but eliminating them from the estimation will result in biased WTP results and, consequently, biased policy propositions by coastal managers.

中文摘要：
海岸侵蚀是一种全球性的普遍现象，预示着未来需要对海岸价值和资产（包括建筑和自然）进行战略管理，我们是否应该投资于旨在保护特定海岸特征的海堤等保护性结构，或允许自然海岸线后退以保护沙滩和其他海岸生态系统。在特定情况下确定最合适的管理方法需要更好地了解人口对沿海资产所持有的全部经济价值，包括非市场价值。在这项研究中，我们描述了新南威尔士州居民花钱维护沙滩（宽度和长度）的意愿。我们使用潜在类二元Logit模型的创新应用来处理Yea-sayers和Nay-sayers，并揭示样本成员之间的潜在异质性。我们发现，65%的人口愿意支付一定数额的税款，这取决于政策设置。在大多数情况下，以沙滩宽度和长度损失5%-100%为特征的海滩恶化程度对受访者支付管理税的意愿没有影响。这表明，同意支付管理税的受访者有动机将沙滩保持在当前状态，而不考虑海岸侵蚀可能造成的沙粒流失的严重程度。支付意愿也因海滩类型而异（在标志性海滩、主要海滩、海湾海滩和冲浪海滩之间），这一发现有助于海岸管理的空间优先顺序。不承认数据中存在反对者，或不承认他们，但将其从估计中消除，将导致有偏见的WTP结果，从而导致沿海管理者有偏见的政策主张。
