Behavioral Economic Traps • Belsky & Gilovich, esp. Chapters 1, 4, 5, & 6 • Behavioral FinanceandBehavioral Economics • both begin with ‘anomalies’ to what should be optimal • The anomalies suggest a broader definition of the goals of the parties or the constraints or costs facing them. Example:Why do we spend more for items bought on credit than when we pay cash?
Rational behavior rational = systematically attempt to achieve a goal the goal may not be praiseworthy, but can still be rational irrational behavior cannot be explained by economists Self-interestedbehavior decision based on the impact on the individual can also be concerned about others as it affects the self Why do people tip? Who is in the best position to assess the friendliness of the server? Prevailing Economic Theory
Trap 1:Decision Paralysis • The phenomenon of decision paralysis causes loss of wealth over time • We see a deal at a price below a previous reference price, then we tend to buy it • If see a deal and yet another deal on a higher quality product, then we tend to delay the decision • The more choice, the harder the choice • Market experiments with products tend to confirm decision paralysis
Bewildering Choice in Financial Products • 7,000 stock and bond funds, and more every day • Yet, billions stashed in CDs & savings accounts • Once a decision is made, the tendency is not to change it • The success of 401(k) investing is that it tends to be a one time decision with automatic investing elements • The relative failure of Roth IRAs because they tend not to be automatic
Warning Signs You may be prone to Decision Paralysis if… • You use Scarlet O’Hara’s approach to investing: “Fiddle-dee-dee, after all tomorrow is another day.” • You cannot make up your own mind, but rely always on the advice of a stranger. • You only select grocery items with signs saying they are on sale. • If you are subject to Decision Paralysis, what can you do about it?
Trap 2:Mental Accounting • The Las Vegas honeymoon story • honeymooner takes $5 chip to roulette wheel • money won in gambling is separated from other monies • phrase: playing with house money • money isn’t fungible under mental accounting • Going to a movie with pre-paid tickets or $ • if lost the tickets or if lost equivalent cash?
Self control forced savings penalties for early withdrawal “Christmas club” savings plans Budgeting & planning gifts tax rebates as “found money viewed as non-essential Different volatilies in sources or uses of funds bonus regular salary tax rebate gift lottery nest egg for a house Motives for Mental Accounts
Credit CardsandMental Accounts • Cash in wallet -- visual evidence of financial loss in purchase • Checking balance -- running subtotal of financial loss in a purchase • Credit card purchase -- harder to remember earlier expenditures, belated accounting of actions • Auction bids for items is HIGHER if participants pay for them with credit cards than with cash UWM
Financial Errors and mental accounts • Retirement savings: invest too conservatively even with 30 years ‘til retirement • Tendency to sell winners and hold losers: though winners have tax injury and selling losers have a tax benefit • Tendency to hold onto home or assets in bequests:though best use may be to liquidate and reinvest
Warning Signs You may be prone to excessive use of Mental Accounts if… • You know to the dime how much is in your 401k plan, but have no idea what your credit card balance is. • You have continuing balances on credit cards, but also have money earning less than 1% in the bank. • How can awareness of your own use of mental accounts be accommodated? • Can you make a full balance sheet of your financial assets and liabilities?
Trap 3:The Sunk Cost Problem • Once committed to a course of action, we feel cognitive dissonance not to continue • Form of ‘Loss Aversion’ when faced with an outcome that is seen as a loss. • Story of the last game for Michael Jordan. You’ve paid $200 for ticket. At the last minute Michael is hurt and won’t play. Do you go? • What if there’s a terrible snow storm?
Problems with Sunk Costs • Half-built large government projects • seen in Nuclear Plants • Example: A certain nameless professor has 2/3rds of a medieval costume. • Did he already get the rest of it? • If stocks fall, we feel we can’t sell. This realizes the loss. • Therefore, we tend to invest in risk-free securities such as money market accounts.
Warning Signs You may be prone to Sunk Cost Problems if… • You want to justify all past decisions as correct • You mention to colleagues the profits you made selling your stock market winners! • What can you do to guard your heart against the Sunk Cost problem? • Do you dwell on past failures, or can you wade them up into a ball and toss them away?
Numbers & Statistics Number Numbness – Chapter 4 Sadly, people make errors with numbers • Money Illusion • You get a 2% raise and you’re happy, even though the inflation rate is 3% • Prices fall 3% and sell your house for 1% less than paid for it. People view this as a loss. • Governments in part raise the supply of money to exploit this illusion of better times

Discussion Questionspage 188 • Why does voluntary action tend not to succeed? • How does the concept of “externalities” apply to India and China? • Taxes on emissions and limits on emission are alternative solutions, but we tend to use limits more often. Why? • If it costs $80,000 per acre to make a wetland, is it worth it?
Trap 4: The Endowment Trap • If given an asset, people are reluctant to give it up. An “endowment effect.” • Value what you have more than if you were to buy it • Give coffee mugs to participants offer to purchase it back for $6, but few take it • Give $6 to to each participant offer to sell mugs for $6, but few purchase • Endowment effect leads to keeping proven losers too long • So also can switching investments too often can be injurious to wealth UWM mug
When already invested in one choice and alternatives are presented, many STAY with whatever is the initial endowment • No service charges at banks with large minimum balance vs. paying a service charge. • People appear to keep large minimum balances, even though more costly than paying a service charge. • If you have a ticket to an event, its value is greater than if you were to bid for it • also an endowment effect • Stay with a mutual fund family, once inside that family

Anchors and First Impressions • The first thing seen or heard can become a reference, an anchor • The order of information affects decisions • First impressionsdominate (anchor) decisions in dating and in business investing • Financial choices can either be viewed as SELECTION of the best or REJECTION of the worst product • Emphasis on risk or emphasis on return shape the thinking.
Beware of Anchors • Price paid for house -- as anchor on selling it • The Power of Suggestion • The agent says life insurance is typically 6 times annual income • The salesman says that others paid $29.95, but for you it is discounted to $19.95 • You’re thinking of selling your house that you paid 80-G for in 1987 and note you are hoping to get 125-G to the prospective RE broker, what do you thinkshe’ll list it for? • Sticker Shock -- as anchor in car purchases

Confirmation Bias • The tendency for new information to be rejected if it doesn’t fit preconceived view • Those who agree with either Geraldo or Rush watch or listen to them; and are confirmed in their opinions • Basis for brand loyalty, “owners groups”, insignia worn on clothes • Form of avoiding cognitive dissonance

Trap 7: Irrational Exuberance • Peer pressure, group psychology, and fads all speak of actions that copy others. • Tulipmania in seventeenth century Holland. • Speculative bubbles as self-fulfilling prophesies • Stock markets and Greenspan’s and Shiller’s Irrational Exuberance • Incorrect rumors can add ‘noise’ to prices of securities
Example: Mutual Fund Returns • The average stock mutual fund earned 12.3% • But the average investor earned only 6.3% • Both true -- so how can we explain this? • Buy and hold vs. switching for optimal asset allocation • Beware of fads in investing
