CAVEAT will identify and mitigate the caveats associated with current valuation methods when applied to culture and heritage capital to inform decision making. CAVEAT will explore how to best triangulate existing valuation techniques to assess the value of the stock (and flows) of a complex historic asset, such as a historic high street/neighbourhood, to improve decision makers' confidence when using such results in Social Cost-Benefit Analysis (SCBS).CAVEAT addresses a key policy and knowledge gap. The protection of heritage assets requires investments in a regime of scarce resources. Historic England's High Street Heritage Action Zone (HSHAZ) programme is an example of how conservation areas may require coordinated actions. Historic High Streets are currently suffering from the impact of businesses closures, and without investment in their conservation and requalification, cities lose a central part of their heritage. A business case for investment requires decision makers to compare costs and benefits of the intervention within a Social Cost Benefit Analysis (SCBS) framework. The main problem they face is to fully account for the economic values (both use and non-use) associated with a cultural asset and articulate their social benefits, which cannot be captured by simple market transactions. A heritage asset is more than its real estate value, or the value people associate with its use. The non-use value, linked to the cultural, aesthetic, and symbolic quality of the asset and/or the emotional attachment that communities have toward it, define such asset as heritage (Throsby, 1999). The only methods able to capture the non-use values associated to cultural heritage are survey-based techniques such as choice experiment and contingent valuation, which can be used to express in monetary terms the social benefits associated to the conservation of historic assets. CAVEAT applies several economic valuation techniques to the same historic high street in an English medium sized city to assess the use and non-use values, and understand the reasons for possible divergence in estimates, sources of bias and ways of minimizing them. These techniques capture use values (such as hedonic pricing (HP) and travel cost (TC) methods) and non-use values (contingent valuation (CV) and discrete choice experiment (DCE) methods). It investigates sources of biases, such as embedding effects (the problem of lack of variation of estimates with respect to the scope of the good) and information effects. It explores the role played by emotional attachment of respondents and compares the estimates of values obtained within the hypothetical setting (CV and DCE) with real-world experiments, where actual transaction for non-use values take place. The results from CV and DCE are then tested against a comparable historic high street in another English city. This tests the reliability of results using benefit transfers (inferring the expected values at the comparable site from results obtained from the first site) between the two sites and suggests ways to minimise possible transfer errors.The main outcome of the project is a guidance for researchers and decision-makers on how to effectively and efficiently triangulate valuation methods for complex assets such as historic high streets/historic neighbourhoods and how to minimise potential biases. CAVEAT provides a framework for the development of future studies. The research will impact the UK cultural sector and beyond. The project team involves two key international heritage stakeholders ICCROM and ICOMOS, engaging governments and experts worldwide.The project team encompasses expertise from various disciplines (architecture, urban planning, heritage conservation, cultural economics, environmental economics, heritage advocacy, policy making support) who have worked on these themes before and are committed to an interdisciplinary approach.

当应用于文化和遗产资本以告知决策时，警告将确定并减轻与当前估值方法相关的警告。警告将探讨如何最好地三角衡量现有的估值技术来评估复杂的历史资产（例如历史悠久的高街/社区）的股票价值（和流动），以提高决策者在社交成本效益分析（SCBS）中使用此类结果时的信心。CAVEAT解决了关键政策和知识差距。保护遗产资产需要在稀缺资源方面进行投资。历史悠久的英格兰高街遗产行动区（HSHAZ）计划是保护区如何需要协调行动的一个例子。历史悠久的大街目前正在遭受关闭企业的影响，而没有对其保护和必要性进行投资，城市就会失去其遗产的中心部分。投资的业务案例要求决策者在社会成本收益分析（SCB）框架内比较干预的成本和收益。他们面临的主要问题是充分说明与文化资产相关的经济价值（使用和不使用），并阐明其社会利益，这无法通过简单的市场交易来捕获。遗产资产超过其房地产价值，或者是与其使用相关的价值。与资产和/或社区对其具有情感依恋的文化，美学和象征性质量相关的不使用价值，将资产定义为遗产（Throsby，1999）。唯一能够捕获与文化遗产相关的不使用值的方法是基于调查的技术，例如选择实验和或有估值，这些技术可用于以货币术语表达与历史资产的保护相关的社会利益。警告将几种经济评估技术应用于英国中型城市的同一历史悠久的高街，以评估使用和不使用的价值，并了解估计，偏见来源以及最小化它们的方式可能发散的原因。这些技术捕获了使用值（例如享乐定价（HP）和旅行成本（TC）方法）和非使用值（偶然的估值（CV）和离散选择实验（DCE）方法）。它研究了偏见的来源，例如嵌入效应（估计范围缺乏估计范围的差异）和信息效应。它探讨了受访者的情绪依恋的作用，并比较了假设设置（CV和DCE）在不使用值的实际交易中，在假设设置（CV和DCE）中获得的值的估计值。然后，对CV和DCE的结果进行了针对另一个英国城市的一条可比历史悠久的高街进行测试。这测试了两个站点之间使用福利转移（从第一个站点获得的结果中的结果中的预期值）测试结果的可靠性，并提出了最小化可能转移误差的方法。该项目的主要结果是研究人员和决策者的指导，以如何有效地和有效地进行诸如历史悠久的高等街道和有效的较高的街区，以供高等街道和有效地进行历史悠久的差异和有效的较高的历史悠久的差异。警告为未来研究的发展提供了一个框架。这项研究将影响英国的文化部门及其他地区。该项目团队涉及两个主要的国际遗产利益相关者库克罗姆（Iccrom and Icomos），吸引了全球政府和专家。该项目团队涵盖了各种学科（建筑，城市规划，遗产保存，文化经济学，环境经济学，环境经济学，遗产倡导，政策制定支持）的专业知识，他们在这些主题上都在这些主题上工作，并从事这些主题的工作。
