The relation between Sen's decomposition of the weak axiom of revealed preferences (WARP), and WARP directional decomposition introduced in Nosratabadi (2017) is investigated. It is argued that the latter generalizes the former. A pairwise transitive WARP decomposition consistent with Sen's...

References can influence choice. One of the well-studied cases is when a decoy is added to the menu. However small in magnitude, decoy effect violates the weak axiom of revealed preferences (WARP). In order to explain the small deviation from the classical revealed preference theory, I decompose...
