Truthful aggregation of budget proposals with additive guarantees

Abstract

In this research, the participatory budgeting problem will be studied, in which each voter submits a proposal for how to divide a single divisible resource (such as money or time) among several possible alternatives (such as public projects or activities) and these proposals must be aggregated into a single aggregate division. We will depart from the single-minded setting considered by Freeman et al. [1] and their mechanisms will be implemented and experimentally analyzed for various objectives
