💰Psychology of Economic Decision-Making Unit 11 – Psych Factors: Saving & Spending Behavior

Key Concepts and Theories

• Behavioral economics combines psychology and economics to understand how people make economic decisions
• Bounded rationality suggests people make decisions based on limited information, cognitive constraints, and time pressure
• Mental accounting categorizes money into different mental accounts (regular income vs. windfall gains) which influences spending and saving behavior
• Prospect theory proposes people make decisions based on potential losses and gains rather than final outcomes
  • Explains loss aversion, where the pain of losing is psychologically twice as powerful as the pleasure of gaining
• Intertemporal choice examines how people make decisions involving tradeoffs between costs and benefits occurring at different times
• Hyperbolic discounting suggests people prefer smaller, immediate rewards over larger, later rewards
  • Leads to present bias, where immediate rewards are disproportionately more compelling

Psychological Factors Influencing Saving

• Self-control plays a crucial role in saving behavior as it requires delaying gratification and resisting temptation to spend
• Financial literacy, including knowledge about interest rates, inflation, and risk diversification, positively correlates with saving behavior
• Personality traits such as conscientiousness and emotional stability are associated with higher saving rates
• Locus of control influences saving behavior, with individuals who have an internal locus of control more likely to save for the future
• Emotion regulation strategies like reappraisal (reframing a situation) can increase saving behavior by reducing the emotional impact of sacrificing current consumption
• Savings goals and mental accounting create dedicated mental accounts for specific purposes (emergency fund, retirement), increasing the likelihood of saving
• Automaticity, such as setting up automatic transfers to savings accounts, reduces the need for self-control and decision-making, promoting saving behavior

Psychological Factors Influencing Spending

• Impulsivity and lack of self-control can lead to overspending and impulsive purchases
  • Delay discounting, the tendency to prefer smaller immediate rewards over larger future rewards, contributes to impulsive spending
• Emotions significantly influence spending decisions, with positive emotions leading to increased spending and negative emotions leading to decreased spending
  • Retail therapy, or making purchases to improve one's mood, exemplifies emotional spending
• Social comparison and a desire to keep up with others can drive overspending, particularly on conspicuous consumption goods
• Scarcity mindset, or the perception of limited resources, can lead to increased spending due to fear of missing out or perceived lack of future opportunities
• Sunk cost fallacy, the tendency to continue investing in something because of past investments, can lead to overspending on failing projects or investments
• Anchoring effect occurs when an initial piece of information (the anchor) influences subsequent judgments and decisions about spending
• Framing effect describes how the way a spending decision is presented (as a gain or a loss) can influence the choice made

Decision-Making Models in Economic Behavior

• Expected Utility Theory assumes people make decisions by weighing the expected utility of each option and choosing the one with the highest expected utility
  • Utility refers to the satisfaction or benefit derived from a good or service
• Prospect Theory proposes that people make decisions based on the potential value of losses and gains rather than the final outcome
  • Explains phenomena like loss aversion and reference dependence
• Bounded Rationality suggests that people make decisions based on limited information, cognitive constraints, and time pressure, leading to satisficing rather than optimizing
• Dual-Process Theory posits that there are two types of thinking: System 1 (fast, automatic, and intuitive) and System 2 (slow, deliberate, and logical)
  • Many economic decisions are made using System 1 thinking, which is more susceptible to biases and heuristics
• Intertemporal Choice models analyze how people make decisions involving tradeoffs between costs and benefits occurring at different times
  • Hyperbolic discounting and present bias are key components of intertemporal choice models
• Heuristics, or mental shortcuts, are often used to simplify complex economic decisions (availability heuristic, representativeness heuristic)
  • While heuristics can be useful, they can also lead to systematic biases in decision-making

Cultural and Social Influences

• Cultural values, such as individualism vs. collectivism, influence spending and saving behavior
  • Collectivistic cultures may prioritize saving for family obligations, while individualistic cultures may prioritize personal consumption
• Social norms and expectations can drive spending behavior, particularly for visible goods and services (weddings, cars)
• Peer influence and social comparison can lead to increased spending to keep up with others' lifestyles
• Family financial socialization, or the process by which children learn about money from their parents, shapes future financial behavior
  • Parental modeling of financial behavior and direct teaching about money influence children's financial habits
• Socioeconomic status affects access to financial resources and education, which in turn influence spending and saving behavior
• Religious and cultural traditions can dictate specific spending patterns (tithing, holiday gift-giving)
• Marketing and advertising play a significant role in shaping consumer preferences and spending behavior
  • Targeted advertising and personalized recommendations can lead to increased spending

Cognitive Biases and Heuristics

• Anchoring bias occurs when an individual relies too heavily on an initial piece of information (the anchor) when making decisions
  • Example: A higher initial price for a product can make the discounted price seem more attractive
• Availability heuristic leads people to overestimate the likelihood of events that are easily remembered or imagined
  • Overestimating the likelihood of winning the lottery due to memorable winners
• Confirmation bias is the tendency to search for, interpret, and recall information in a way that confirms one's preexisting beliefs
  • Seeking out information that supports a desired purchase while ignoring contradictory information
• Framing effect describes how presenting the same option in different ways (positive vs. negative framing) can influence decisions
  • Presenting a credit card fee as a "$50 late fee" vs. a "$50 on-time payment discount"
• Hyperbolic discounting leads people to prefer smaller, immediate rewards over larger, later rewards
  • Choosing a smaller immediate cash bonus over a larger retirement contribution
• Mental accounting refers to the tendency to categorize and treat money differently based on its source or intended use
  • Spending unexpected windfalls more freely than regular income
• Sunk cost fallacy is the tendency to continue investing in a losing proposition because of past investments
  • Continuing to invest in a failing business venture due to the time and money already spent

Practical Applications and Interventions

• Automatic enrollment in retirement savings plans significantly increases participation rates by leveraging the power of defaults
• Commitment devices, such as self-imposed penalties for failing to reach a savings goal, can help individuals overcome present bias and stick to long-term goals
• Financial education programs can improve financial literacy and decision-making, particularly when combined with practical experience and timely interventions
• Framing financial decisions in terms of potential losses rather than gains can leverage loss aversion to encourage desired behavior (saving more, spending less)
• Goal setting and mental accounting can create dedicated savings accounts for specific purposes, increasing motivation to save
• Limiting consumer choice can reduce decision fatigue and lead to better financial decisions
  • Simplifying investment options in a retirement plan
• Providing timely reminders and feedback can help individuals stay on track with financial goals and avoid impulsive spending
• Restructuring the choice architecture, such as setting smaller default portion sizes or placing healthier items at eye level, can nudge individuals towards better decisions

Case Studies and Real-World Examples

• Save More Tomorrow program: Employees commit to automatically increasing their retirement contributions with each future pay raise, leveraging inertia and hyperbolic discounting
• Peer-to-peer lending platforms (Lending Club, Prosper): Leverage social proof and the identifiable victim effect to encourage lending
• Mobile banking apps (Acorns, Digit): Use rounding up spare change and automatic transfers to make saving feel less painful
• Credit card minimum payments: Anchoring effect leads many consumers to pay only the minimum due, resulting in higher interest charges over time
• Extended warranties: Framing effect and loss aversion lead consumers to overvalue the protection against potential losses
• Black Friday sales: Scarcity mindset and social proof drive impulse purchases, even when the deals are not exceptional
• Grocery store layouts: Placing essential items at the back of the store and tempting items near the checkout leverages impulse spending
• Microlending programs (Kiva, Grameen Bank): Leverage the identifiable victim effect and social proof to encourage lending to low-income entrepreneurs
