behavioral finance
The study of how psychological factors and biases influence financial decisions and market outcomes.
What research laid the foundation for behavioral finance?
Work by Kahneman and Tversky on decision-making under uncertainty, including Prospect Theory.
How does behavioral finance differ from traditional finance?
Traditional finance assumes rational investors; behavioral finance recognizes cognitive and emotional biases that lead to irrational decisions.
Nobel Prize winners associated with behavioral finance?
Daniel Kahneman (2002), Robert Shiller (2013), Richard Thaler (2017).
What book popularized behavioral finance concepts?
Thinking, Fast and Slow by Daniel Kahneman.
Explain how behavioral finance theory evolved over time.
It began with psychology-based research on decision-making, expanded through Prospect Theory, and integrated into wealth management practices emphasizing behavioral coaching.
What is intuitive decision-making?
Fast, automatic, emotional thinking (System 1).
What is deliberative decision-making?
Slow, analytical, logical thinking (System 2).
Describe biological processes in financial decision-making.
Emotional triggers activate the limbic system, influencing risk perception and decisions, while rational thinking engages the prefrontal cortex.
What is Expected Value Theory?
Optimal decision rule where decisions aim to maximize expected monetary value.
EV = Σ (Probability × Outcome).
What is Utility Function Theory?
A model where decisions aim to maximize satisfaction (utility), not just monetary value.
Difference between descriptive vs. prescriptive utility theory?
Descriptive explains actual behavior; prescriptive suggests optimal behavior.
What is the Mean-Variance Model?
A portfolio theory model that balances expected return against risk (variance).
What is Prospect Theory?
A behavioral model showing people weigh losses more heavily than gains, leading to loss aversion and risk-seeking in losses.
What is the Adaptive Market Hypothesis?
Suggests markets evolve like biological systems, adapting to changing environments and investor behaviors.
a framework for connecting the theories of efficient markets with the findings of behavioral economics
sometimes investors act rational, sometimes they act irreational
What is a behavioral bias?
A systematic deviation from rational judgment caused by cognitive or emotional factors.
Define loss aversion.
Feeling losses about twice as strongly as equivalent gains.
Define herding bias.
Following the crowd rather than independent analysis.
Define recency bias.
Overweighting recent events when making decisions.
Define availability bias.
Relying on information that is most easily recalled or readily available.
Define overconfidence bias.
Overestimating one’s own knowledge or predictive ability.
What is framing bias?
Decisions influenced by how information is presented (gain vs. loss framing).
What is mental accounting?
Treating money differently based on its source or intended use.
What is anchoring bias?
Relying too heavily on an initial reference point when making decisions.
