- leads to overestimation of easily recalled event probabilities, influencing financial risk perception (stock market crashes)
- Loss aversion describes preference for avoiding losses over acquiring equivalent gains, impacting investment and spending behaviors
- Example: Holding onto losing stocks longer than profitable ones
- occurs when individuals rely too heavily on initial information for decisions, affecting price negotiations and valuations
- Example: Using list price as a starting point in real estate negotiations
- leads to overestimation of abilities and prediction accuracy, influencing investment strategies and market participation
- Present bias (hyperbolic discounting) places greater value on immediate rewards compared to future ones, affecting saving and long-term financial planning
- Example: Choosing a smaller immediate bonus over a larger future raise
- demonstrates how information presentation alters decision-making, impacting consumer choices and policy interpretations
- Example: Presenting a product as "95% fat-free" versus "5% fat" to influence purchasing decisions
Cognitive Biases in Market Behavior
- , influenced by social proof bias, leads to and crashes as investors follow the crowd rather than fundamental analysis

Key Terms to Review (27)
Amos Tversky: Amos Tversky was a pioneering cognitive psychologist known for his groundbreaking work in decision-making and behavioral economics, particularly in collaboration with Daniel Kahneman. His research highlighted how people often deviate from traditional economic theories and rationality due to cognitive biases, which has reshaped our understanding of human decision-making processes.
Anchoring Bias: Anchoring bias is a cognitive bias where individuals rely too heavily on the first piece of information encountered when making decisions, which serves as a reference point for future judgments. This bias can skew perceptions and lead to poor decision-making in various contexts, including economic and financial settings.
Availability heuristic: The availability heuristic is a mental shortcut that relies on immediate examples that come to mind when evaluating a specific topic, concept, method, or decision. This cognitive bias can lead individuals to overestimate the importance or frequency of events based on how easily they can recall similar instances, influencing various economic behaviors and decisions.
Behavioral Nudges: Behavioral nudges are subtle prompts or changes in the way choices are presented to influence people’s decision-making without restricting their freedom of choice. These nudges leverage insights from psychology and behavioral economics to guide individuals toward more beneficial choices, often by altering the context in which decisions are made. The aim is to help individuals make decisions that can lead to better outcomes, while still maintaining their autonomy.
Bounded rationality: Bounded rationality refers to the concept that individuals make decisions based on limited information and cognitive limitations, rather than striving for complete rationality. This means that while people aim to make the best choices, they often rely on heuristics and simplified models, leading to decisions that may be satisfactory but not necessarily optimal.
Cognitive Dissonance: Cognitive dissonance is the psychological discomfort that arises when a person holds two or more contradictory beliefs, values, or attitudes, especially when their behavior conflicts with these beliefs. This discomfort often leads individuals to change their beliefs or behaviors to restore harmony and reduce the dissonance they experience. Understanding cognitive dissonance is crucial because it can influence economic decisions, investments, and consumer behavior, revealing how people rationalize their choices and manage conflicting information.
Cognitive Mechanisms: Cognitive mechanisms refer to the mental processes and structures that underlie our thinking, reasoning, and decision-making. These processes help individuals interpret information, solve problems, and make choices, often influenced by cognitive biases that can lead to suboptimal economic outcomes. Understanding these mechanisms is crucial for grasping how people navigate economic decisions and the subsequent implications on markets and behaviors.
Confirmation bias: Confirmation bias is the tendency to search for, interpret, and remember information in a way that confirms one’s preexisting beliefs or hypotheses, while giving disproportionately less consideration to alternative possibilities. This cognitive shortcut can heavily influence economic decision-making by shaping perceptions and choices based on selective evidence.
Daniel Kahneman: Daniel Kahneman is a renowned psychologist known for his work in behavioral economics, particularly in understanding how psychological factors influence economic decision-making. His research challenges traditional economic theories by highlighting the cognitive biases and heuristics that impact people's choices, ultimately reshaping the way we think about rationality in economics.
Endowment Effect: The endowment effect is a cognitive bias where individuals value an item more highly simply because they own it. This phenomenon impacts how people make economic decisions, leading to irrational behaviors that deviate from traditional economic theories.
Experimental Economics: Experimental economics is a branch of economics that utilizes controlled experiments to test economic theories and observe decision-making processes in a structured environment. By manipulating variables and observing participants' responses, researchers can gain insights into how cognitive biases, social preferences, and cooperation influence economic behavior, leading to a better understanding of real-world economic interactions.
Framing effect: The framing effect refers to the phenomenon where people's decisions are influenced by how information is presented or 'framed,' rather than just by the information itself. This can significantly alter perceptions and choices, impacting economic decisions, as different presentations can lead to different interpretations and outcomes.
Herding Behavior: Herding behavior refers to the tendency of individuals to mimic the actions of a larger group, often leading to collective decision-making that may not reflect individual preferences or rationality. This phenomenon is especially relevant in economic contexts, where it can influence market trends, investor behavior, and the diffusion of information.
Irrational Exuberance: Irrational exuberance refers to the phenomenon where investors' enthusiasm drives asset prices to levels that exceed their intrinsic value, often leading to market bubbles. This term highlights the disconnect between rational economic fundamentals and investor psychology, indicating how emotions and cognitive biases can impact economic decision-making.
Loss Aversion: Loss aversion refers to the psychological phenomenon where people prefer to avoid losses rather than acquire equivalent gains, implying that the pain of losing is psychologically more impactful than the pleasure of gaining. This concept connects deeply with how individuals make economic decisions, influencing behaviors across various contexts such as risk-taking, investment choices, and consumer behavior.
Market Bubbles: Market bubbles occur when the prices of assets inflate to levels that exceed their intrinsic value, driven by irrational investor behavior and speculative trading. These bubbles can form in various markets, such as real estate or stock markets, often fueled by cognitive biases and overconfidence, leading to a disconnect between perceived value and actual worth. When the bubble bursts, it can result in significant financial losses and economic instability.
Mental Accounting: Mental accounting refers to the cognitive process by which individuals categorize, evaluate, and track their financial resources. This concept highlights how people create separate 'accounts' in their minds for different types of expenses or incomes, which can lead to irrational financial behaviors and decisions.
Nudge Theory: Nudge Theory is a concept in behavioral economics that suggests subtle changes in the way choices are presented can significantly influence people's decisions and behaviors without restricting their options. This theory emphasizes how choice architecture can lead to better decision-making outcomes, highlighting the importance of context in economic decision-making.
Overconfidence Bias: Overconfidence bias is a cognitive bias that leads individuals to overestimate their knowledge, abilities, and the accuracy of their predictions. This bias can significantly influence economic behavior by skewing decision-making processes and leading to excessive risk-taking, as people believe they are more capable than they actually are.
Policy Framing: Policy framing refers to the way information about a particular policy or issue is presented and structured, influencing how individuals perceive and interpret that information. This concept highlights the importance of context and language in shaping opinions and decision-making processes, ultimately impacting economic behavior and public policy outcomes.
Present Bias: Present bias refers to the tendency of individuals to give stronger weight to immediate rewards over future rewards, often leading to choices that prioritize short-term satisfaction over long-term benefits. This cognitive bias impacts various economic behaviors, highlighting the struggle between immediate desires and future planning.
Prospect Theory: Prospect theory is a behavioral economic theory that describes how individuals evaluate potential losses and gains when making decisions under risk. It highlights the way people perceive gains and losses differently, leading to decisions that often deviate from expected utility theory, particularly emphasizing the impact of loss aversion and reference points in their choices.
Recency Bias: Recency bias is the tendency for individuals to give undue weight to recent events or experiences when making decisions, often leading to distorted perceptions and judgments. This bias can significantly influence economic behavior, as people may rely on recent information to form expectations or make predictions, potentially neglecting historical data that could provide a more balanced view. Understanding this bias is essential for analyzing decision-making processes, particularly in contexts where timing and the flow of information are crucial.
Self-serving bias: Self-serving bias is the tendency for individuals to attribute their successes to internal factors, like their skills or efforts, while blaming external factors for their failures. This cognitive distortion helps maintain self-esteem and a positive self-image but can distort perceptions and decision-making. It plays a significant role in understanding how people interpret economic outcomes and the rationalizations they use when assessing their own performance versus that of others.
Status Quo Bias: Status quo bias is a cognitive bias that leads individuals to prefer the current state of affairs and resist change, even when alternatives may offer better outcomes. This bias often stems from a fear of loss or uncertainty and can significantly impact decision-making in various economic contexts.
Sunk Cost Fallacy: The sunk cost fallacy refers to the tendency for individuals to continue investing in a decision based on the cumulative prior investment (time, money, resources) rather than on current or future benefits. This irrational decision-making process often leads to further losses as people feel compelled to justify their earlier investments.
Surveys: Surveys are systematic methods of collecting data from a predefined group, often through questionnaires or interviews, aimed at understanding opinions, behaviors, or characteristics. They play a crucial role in economic decision-making by providing insights into consumer preferences, market trends, and the impact of cognitive biases.
