Abstract

The paper proposes a unification of the two main frameworks commonly used for the analysis of collective decision-making: the framework of preference aggregation, developed from the seminal work of K. Arrow on social choice theory; and the more recent framework of judgment aggregation. Such unification provides several original insights on collective decision-making problems. The methods used are based on logic and, in particular, on formal semantics.
