   abstract = {A public divisible resource is to be divided among projects. We study rules that decide on a distribution of the budget when voters have ordinal preference rankings over projects. Examples of such portioning problems are participatory budgeting, time shares, and parliament elections. We introduce a family of rules for portioning, inspired by positional scoring rules. Rules in this family are given by a scoring vector (such as plurality or Borda) associating a positive value with each rank in a vote, and an aggregation function such as leximin or the Nash product. Our family contains well-studied rules, but most are new. We discuss computational and normative properties of our rules. We focus on fairness, and introduce the SD-core, a group fairness notion. Our Nash rules are in the SD-core, and the leximin rules satisfy individual fairness properties. Both are Pareto-efficient.}

+\emph{Participatory Budgeting} (PB) is a process of democratic deliberation that
+allows residents of a municipality to decide how a part of the public budget is
+to be spent. It is a way to improve transparency and citizen involvement which
+are two important cornerstones of a democracy. PB was first realized in the
+1990s in Porto Alegre in Brazil by the Workers' Party to combat the growing
+divide between the rich city center and the poor living in the greater region.
+Owing to its success in the south of Brazil, PB quickly spread to North America,
+Europe, Asia and Africa.
+
+Although the process is heavily adapted by each municipality to suit the
+environment in which the residents live in, it generally follows the following
+stages \autocite{participatorybudgetingprojectHowPBWorks}:
+
+\begin{description}
+    \item [Design the process] A rule book is crafted to ensure that the process
+        is democratic.
+    \item [Collect ideas] Residents propose and discuss ideas for projects.
+    \item [Develop feasible projects] The ideas are developed into projects that
+        can be undertaken by the municipality.
+    \item [Voting] The projects are voted on by the residents.
+    \item [Aggregating votes \& funding] The votes are combined to determine a
+        set of winning projects which are then funded.
+\end{description}
+
+\noindent The two last stages \emph{voting} and \emph{aggregating votes} are of
+main interest for computer scientists, economists and social choice theorists
+because depending on how voters elicit their preferences (\emph{balloting}) and
+how the votes are aggregated through the use of algorithms, the outcome is
+different.
+
+\textcite{azizParticipatoryBudgetingModels2020} define a taxonomy of
+participatory budgeting scenarios where projects can be either divisible or
+indivisible and bounded or unbounded.
+
+\subsection{Participatory budgeting scenario}
+\label{subsec:Participatory budgeting scenario}
+
+Formally, a PB scenario consists of a set of projects $P = \{ p_1,\dots,p_m \}$
+where each project $p\in P$ has an associated cost $c(p):P\rightarrow\mathbb{R}$.
