We study random joint choice rules, allowing for interdependence of choice across agents.
These capture random choice by multiple agents, or a single agent across goods or time …

We provide two nested models of random reference-dependent choice in which the
reference point is endogenously determined by random processes. Random choice …

We propose and characterize a class of stochastic decision functions for a decision-maker
who has a capacity for processing at most k-alternatives at a time. When faced with a menu …

Multivalued choice rules, or choice correspondences, are effective means to describe a wide
array of behaviors conforming to and deviating from rationality. Modeling heterogeneity in …

We examine the effect of item arrangement on choices using a novel decision-making model
based on the Markovian exploration of choice sets. This model is inspired by experimental …

The degree to which consumers treat different options as distinct or differentiated is a key
determinant of market competition and pricing. To facilitate the measurement of …

We propose a boundedly rational model of choice where agents eliminate dominated
alternatives using a transitive rationale before making a choice using a complete rationale …

I propose a procedural model of random choice called visual choice based on the eye
movements of individuals. The decision maker fixates randomly on alternatives, and …

In this dissertation, I model individuals who have limited attention due to different reasons
and the impact of this on the market competition. I propose three theoretical models two of …

Measurement error is an important concern in empirical and experimental work on discrete
choice. Ignoring it may lead to an (under) over rejection problem, whereby observed choices …
