This paper examines elements of the complex place/role/influence of psychology in the history of consumer choice theory. The paper reviews, and then challenges, the standard narrative that psychology was "in" consumer choice theory early in the neoclassical revolution, then strictly "out" during...

We provide a nonparametric 'revealed preference' characterization of rational household behavior in terms of the collective consumption model, while accounting for general (possibly non-convex) individual preferences. We establish a Collective Axiom of Revealed Preference (CARP), which provides...

Many studies document failures of expected utility’s key assumption, the independence axiom. Here, we show that independence can be decomposed into two distinct axioms - betweenness and homotheticity - and that these two axioms are necessary and sufficient for independence. Thus, independence...

Sharp nonparametric bounds are derived for Hicksian compensating and equivalent variations. These 'i-bounds' generalize earlier results of Blundell, Browning and Crawford (2008). We show that their e-bounds are sharp under the Weak Axiom of Revealed Preference (WARP). They do not require...

We develop a revealed preference approach to analyze non-unitary consumption models with intrahousehold allocations deviating from the cooperative (or Pareto efficient) solution. At a theoretical level, we establish revealed preference conditions of household consumption models with varying...

We derive revealed preference tests for models where individuals use consideration sets to simplify their consumption problem. Our basic test provides necessary and sufficient conditions for consistency of observed choices with the existence of consideration set restrictions. The same conditions...

This paper presents a nonparametric analysis of a common class of intertemporal models of consumer choice that relax consumption independence. Within this class and in the absence of any functional form restrictions on instantaneous preferences, we compare the revealed preference conditions for...

Reference-dependent choice behavior implies behavioral anomalies such as the so-called attraction effect, status quo bias, and endowment effect. This paper builds a new theory of revealed preference capturing preferences that depend on a reference point. The first main contribution of this work...

When making choices, decision makers often either lack information about alternatives or lack the cognitive capacity to analyze every alternative. To capture these situations, we formulate a framework to study behavioral search by utilizing the idea of consideration sets. Consumers engage in a...

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...
