Social Choice and Public Choice are theories that share theoretical assumptions. Nevertheless, each one offers different solutions to the instability problem of decision making.This article seeks to clarify the similarities and differences between these theories. In a nutshell, social choice studies the aggregation of individual preferences;the theory assumes that individuals have ordinal preferences and that these actors do not interact with each other. In contrast, public choice maintains that political decisions are the result of interactions, particularly exchanges among political actors who value issues with different intensity.

Keywords : social choice; public choice; logrolling; impossibility theorem; median voter theorem; structural induced equilibrium.
