We introduce an end-to-end model of participatory budgeting grounded in social choice theory. This model accounts for both the first stage, in which participants propose projects to be shortlisted, and the second stage, in which they vote on which of the shortlisted projects should be funded. We introduce several shortlisting rules for the first stage and we analyse them in both normative and algorithmic terms. Our main focus is on the incentives of participants to engage in strategic behaviour, especially in the first stage, in which they need to reason about how their proposals will impact the range of strategies available to everyone in the second stage.

翻译：我们提出了一种基于社会选择理论的参与式预算端到端模型。该模型涵盖两个阶段：第一阶段，参与者提出项目以形成候选名单；第二阶段，他们投票决定候选名单中的哪些项目应获得资助。我们为第一阶段引入了若干入围规则，并从规范性与算法性两个维度展开分析。我们的核心关注点在于参与者采取策略行为的动机，尤其是在第一阶段——他们需要思考自己的提案将如何影响第二阶段中所有参与者可用的策略范围。
