Economics - Prospect Theory

A behavioral economic theory that describes how individuals make decisions under uncertainty, focusing on the psychological factors that influence decision-making.

Decision-Making Under Uncertainty

The process of making choices when the outcomes are uncertain, and individuals have incomplete information about the probabilities of different outcomes.

Loss Aversion

The tendency for individuals to prefer avoiding losses over acquiring equivalent gains, leading to risk-averse behavior and irrational decision-making.

Framing Effects

The influence of the way information is presented (framed) on individuals' decisions and judgments, even when the underlying content is the same.

Prospect Theory vs. Expected Utility Theory

A comparison between Prospect Theory and Expected Utility Theory, highlighting the differences in how they model decision-making under uncertainty and incorporate psychological biases.

Applications of Prospect Theory

The practical implications and real-world applications of Prospect Theory in various fields, such as finance, marketing, and public policy.

Critiques and Limitations

The criticisms and limitations of Prospect Theory, including its reliance on subjective judgments, limited scope, and challenges in empirical testing.

Experimental Evidence

The experimental studies and empirical evidence that support and validate the predictions and insights of Prospect Theory.

Behavioral Economics

A field of study that combines insights from psychology and economics to understand and explain deviations from rational decision-making in real-world economic behavior.

Endowment Effect

The tendency for individuals to value an item they own more than an identical item they do not own, leading to irrational behavior in economic transactions.

Reference Dependence

The idea that individuals evaluate outcomes relative to a reference point, such as their current wealth or status quo, influencing their perception of gains and losses.

Probability Weighting

The phenomenon where individuals overweight small probabilities and underweight large probabilities when making decisions under uncertainty, leading to risk-seeking or risk-averse behavior.

Certainty Effect

The tendency for individuals to overweight outcomes that are certain compared to outcomes that are merely probable, leading to risk-averse behavior in the domain of gains and risk-seeking behavior in the domain of losses.

Reflection Effect

The observation that individuals tend to be risk-averse when facing gains and risk-seeking when facing losses, reflecting a departure from expected utility theory.

Sunk Cost Fallacy

The tendency for individuals to continue investing resources into a project or decision based on the cumulative costs already incurred, even when the future benefits are unlikely or negative.

Mental Accounting

The cognitive process where individuals categorize and evaluate economic outcomes separately, leading to irrational behavior in financial decision-making.

Availability Heuristic

The mental shortcut where individuals make judgments and decisions based on the ease with which examples or instances come to mind, often leading to biased and inaccurate assessments.

Framing Bias

The tendency for individuals to be influenced by the way information is presented (framed), leading to different decisions or preferences based on the framing of the same information.

Anchoring and Adjustment

The cognitive bias where individuals rely heavily on an initial piece of information (the anchor) and make adjustments from that anchor when making judgments or estimates.

Losses Loom Larger Than Gains

The psychological phenomenon where losses have a greater impact on individuals' well-being and decision-making compared to equivalent gains, leading to risk-averse behavior and loss aversion.

Prospect Theory's Value Function

The S-shaped value function in Prospect Theory that describes how individuals perceive and evaluate gains and losses, showing diminishing sensitivity to changes in magnitude.

Framing of Risk

The way in which risk is presented or framed, influencing individuals' risk preferences and decisions, even when the underlying probabilities and outcomes are the same.

Endowment Effect Reversal

The reversal of the endowment effect, where individuals value an item more when they do not own it compared to when they own it, challenging the traditional understanding of ownership and valuation.

Status Quo Bias

The tendency for individuals to prefer the current state of affairs (status quo) and resist change, even when the alternative options may be objectively better.

Framing of Time

The way in which time is presented or framed, influencing individuals' decisions and preferences related to future outcomes and intertemporal choices.

Certainty Effect Reversal

The reversal of the certainty effect, where individuals become risk-seeking for certain gains and risk-averse for certain losses, challenging the predictions of expected utility theory.

Prospect Theory's Probability Weighting Function

The inverse S-shaped probability weighting function in Prospect Theory that describes how individuals distort probabilities when making decisions under uncertainty, overweighting small probabilities and underweighting large probabilities.

Framing of Social Norms

The way in which social norms and expectations are presented or framed, influencing individuals' behavior and decisions in social and economic contexts.

Regret Theory

An extension of Prospect Theory that incorporates the emotion of regret into decision-making, focusing on the anticipation and avoidance of regret in choices.

Dual-System Model

The cognitive model that distinguishes between two decision-making systems: the intuitive, automatic system (System 1) and the deliberative, reflective system (System 2).

Framing of Effort

The way in which effort is presented or framed, influencing individuals' motivation, willingness to exert effort, and perception of the value of rewards.

Prospect Theory's Loss Aversion

The asymmetry in individuals' responses to gains and losses, where losses have a greater psychological impact than equivalent gains, leading to risk-averse behavior and loss aversion.

Neuroeconomic Studies

The interdisciplinary field that combines neuroscience and economics to study the neural mechanisms underlying decision-making and the psychological biases described by Prospect Theory.

Framing of Social Identity

The way in which social identity and group membership are presented or framed, influencing individuals' behavior, attitudes, and decisions in social and economic contexts.

Prospect Theory's Reference Point

The baseline or reference point against which individuals evaluate gains and losses, influencing their perception of outcomes and the shape of the value function in Prospect Theory.

Framing of Incentives

The way in which incentives and rewards are presented or framed, influencing individuals' motivation, effort, and decision-making in economic and organizational settings.

Prospect Theory's Diminishing Sensitivity

The observation that individuals exhibit diminishing sensitivity to changes in magnitude, perceiving smaller changes in outcomes as relatively larger when they are near the reference point.

Framing of Fairness

The way in which fairness and equity are presented or framed, influencing individuals' perceptions of fairness, cooperation, and distributive justice in economic and social interactions.

Prospect Theory's Probability Distortion

The distortion of probabilities in individuals' decision-making, where small probabilities are overweighted and large probabilities are underweighted, leading to risk-seeking or risk-averse behavior.

Framing of Trust

The way in which trust and trustworthiness are presented or framed, influencing individuals' trust-related decisions, cooperation, and social interactions.

Prospect Theory's Certainty Effect

The observation that individuals exhibit risk-averse behavior for gains and risk-seeking behavior for losses when the outcomes are certain, deviating from the predictions of expected utility theory.

Framing of Health Risks

The way in which health risks and medical information are presented or framed, influencing individuals' perceptions, decisions, and behaviors related to health and healthcare choices.

Prospect Theory's Reflection Effect

The tendency for individuals to exhibit risk-averse behavior when facing gains and risk-seeking behavior when facing losses, reflecting a departure from the predictions of expected utility theory.

Framing of Climate Change

The way in which climate change and environmental issues are presented or framed, influencing individuals' attitudes, beliefs, and actions related to climate change mitigation and adaptation.

Prospect Theory's Mental Accounting

The cognitive process where individuals categorize and evaluate economic outcomes separately, leading to irrational behavior in financial decision-making and the allocation of resources.
