Preferences, decision-making behaviour of households and public good provision

为了理解在动态变化的框架条件下农村-城市界面的结构变化和公共产品的提供，我们建议分析社会和环境偏好、个人投资和撤资决策及其与公共产品结果的关联。更具体地说，该项目旨在解决四个目标：第一，我们分析影响个人风险、时间、社会和环境偏好的因素及其在城乡交界处的演变。其次，我们考察了城乡梯度上家庭的投资和撤资决策。特别是，我们将测试经典投资理论和实物期权方法中哪个更适合预测投资和撤资决策。第三，我们结合数据分析了个人投资和撤资行为在多大程度上可以由个人特征和偏好以及城市化引发的框架条件变化来解释。第四，考察了社会经济特征和偏好与环境公共产品提供之间的关系。为了解决上述研究目标，我们将与C05合作，从班加罗尔两个城乡交错带沿线的1200个家庭收集数据。这将构成FOR2432中其他项目的总体抽样框架，该框架将适用于本项目中受访家庭的子样本(B01、B02、B03、A03)，或从调查家庭中选择的农场研究地点(A01、A02、C01)。将使用标准化问卷收集有关社会经济家庭特征、社会和环境偏好以及生活满意度的数据。信任、风险和时间偏好将通过整合到调查中的实验游戏来引出。此外，我们将使用离散选择实验来获得与B01合作确定的不同生态系统服务的环境偏好。我们还将编制一份详细的清单，列出社会经济住户调查所包括的每个社区提供的公共物品。最后，将对600户家庭进行行为实验，以调查投资和撤资决策以及对公共利益的贡献。

In order to understand structural change and the provision of public goods along the rural-urban interface under dynamically changing framework conditions, we propose to analyze social and environmental preferences, individual investment and disinvestment decisions and their associations with public good outcomes. More specifically, the project aims to address four objectives: First, we analyse the factors influencing individual risk, time, social and environmental preferences and their evolution along the rural-urban interface. Second, we investigate investment and disinvestment decisions of households along the rural-urban gradient. In particular, we will test whether the classical investment theory or the real options approach is more appropriate to predict investment and disinvestment decisions. Third, we combine the data to analyse in how far individual investment and disinvestment behaviour can be explained by individual characteristics and preferences as well as changing framework conditions as induced by urbanization. Fourth, we investigate the relationship between socio-economic characteristics and preferences and the provision of environmental public goods. In order to address the above research objectives, we will collect data from 1,200 households along two rural-urban transects of Bangalore in collaboration with C05. This will constitute the overall sampling framework for other projects within FOR2432, which will work with sub-samples of the households interviewed in this project (B01, B02, B03, A03), or at on-farm research sites chosen from the surveyed households (A01, A02, C01). A standardized questionnaire will be used to collect data on socio-economic household characteristics, social and environmental preferences and life satisfaction. Trust, risk, and time preferences will be elicited using experimental games integrated into the survey. In addition, we will use discrete choice experiments to obtain environmental preferences regarding different ecosystem services identified in collaboration with B01. We will also compile a detailed inventory of public goods provided in each of the neighbourhoods included in the socio-economic household survey. Finally, behavioural experiments will be carried out with a sub-sample of 600 households to investigate investment and disinvestment decisions as well as contributions to a public good.
