Definition

Behavioral economics is an interdisciplinary field that integrates insights from psychology to study how cognitive, emotional, and social factors systematically influence human economic decision-making, often leading to deviations from the predictions of traditional rational choice models.

Key Figures

Preference Construction Era era

Amos Tversky [1], a central figure in the Preference Construction Era, is associated with Stanford University [3] and the University of British Columbia [4] during this period. His key contributions in this era center on framing effects and reference-dependent preferences, as articulated in The Framing of Decisions and the Psychology of Choice [6], Loss Aversion in Riskless Choice: A Reference-Dependent Model [7], and Elimination by aspects: A theory of choice [8], which collectively challenged stable-utility models by foregrounding context, losses, and stepwise elimination as determinants of choice. Daniel Kahneman [2], whose affiliations during the era include Harvard University [5] and Stanford University [3], helped shape the empirical program and methodological realism that defined the period. Their collaborative work—The Framing of Decisions and the Psychology of Choice [6] and Loss Aversion in Riskless Choice: A Reference-Dependent Model [7]—advanced constructionist theories of preference and helped define the bounded rationality program that characterized the era.

Experimental Formalization Era era

John H. Cochrane[1], with ties to the University of Washington[3] and the University of California, Los Angeles[4], emerged as a central figure in shaping the Experimental Formalization Era. His work, notably the 1999 paper By Force of Habit: A Consumption-Based Explanation of Aggregate Stock Market Behavior[7], introduced habit-based consumption mechanisms into asset-pricing discussions, providing a formal link between behavioral patterns and macro-financial models. John Y. Campbell[2], affiliated with Harvard University[5] and Princeton University[6], contributed to the era by advancing consumption-based explanations of aggregate asset prices. These contributions helped articulate intertemporal choice and reference-dependence within microeconomic and financial frameworks, enabling cross-checks with field data and supporting the replication-centered evolution of the era[7].

Policy Translation Era era

Richard L. Oliver [1] is associated with Vanderbilt University [3] and the University of Akron [4] during this era. His key contribution in this era is the paper "Satisfaction: a behavioral perspective on the consumer" [7], which reframes consumer satisfaction through behavioral insights and informs policy-oriented measurement and interventions. Dan Ariely [2] is associated with Harvard University [5] and the Massachusetts Institute of Technology [6] during this era. His paper "Doing Good or Doing Well? Image Motivation and Monetary Incentives in Behaving Prosocially" [8] contributed to understanding how image concerns and monetary incentives shape prosocial behavior, a foundation for policy-instrument design in the Policy Translation Era.
