We introduce a new approach for designing rules for participatory budgeting, the problem of deciding on the use of public funds based directly on the views expressed by the citizens concerned. The core idea is to embed instances of the participatory budgeting problem into judgment aggregation, a powerful general-purpose framework for modelling collective decision making. Taking advantage of the possibilities offered by judgment aggregation, we enrich the familiar setting of participatory budgeting with additional constraints, namely dependencies between projects and quotas regarding different types of projects. We analyse the rules obtained in both algorithmic and axiomatic terms.

我们引入了一种设计参与式预算规则的新方法，即直接根据有关公民表达的意见来决定公共资金的使用的问题。核心思想是将参与式预算问题的实例嵌入到判断聚合中，这是一个用于建模集体决策的强大通用框架。利用判断聚合提供的可能性，我们通过额外的约束来丰富参与式预算的熟悉设置，即项目之间的依赖性和不同类型项目的配额。我们分析了算法和公理方面获得的规则。
