A cooperative-competitive perspective of ownership necessitates an understanding of ownership disagreements.

Boyer's cognitive model of ownership, based on cooperation and competition, underscores the importance of studying disagreements in ownership. We argue that exploring the factors that can lead to different perceptions and experiences of ownership will uniquely inform our understanding of legal, psychological, and perceived ownership beliefs.

Scarcity and intertemporal choice.

Scarcity often encourages decisions that favor the present over the future. While prevailing theories largely attribute these decisions to myopic, impulsive decision making, five studies find support for an alternative, less prevalent perspective. We introduce the time horizon of threatened needs as an important determinant of scarcity's effect on intertemporal choice, demonstrating that people's decisions under scarcity reflect attempts to address threatened needs.

Each year, eligible individuals forgo billions of dollars in financial assistance in the form of government benefits. To address this participation gap, we identify psychological ownership of government benefits as a factor that significantly influences individuals' interest in applying for government benefits. Psychological ownership refers to how much an individual feels that a target is their own.
