140. How to Think About Money, Choose Your Hometown, and Buy an Electric Toothbrush

Episode Summary

Executive Summary: This FAQ-style Freakonomics Radio episode explores how people make financial and location decisions through the lens of behavioral economics. Levitt and Dubner discuss why cash feels more painful than credit, how mental accounting shapes spending, why young people may be too thrifty, and how to choose a hometown based on amenities, schools, density, and lifestyle preferences.

Main Topics: Cash vs. credit card spending (Priority: 5/5): A listener asks whether younger people treat credit cards and cash differently. Levitt argues that paying with cash feels more painful because the money leaves your pocket immediately, while credit delays the pain and can increase willingness to pay. Mental accounting and irrational spending (Priority: 5/5): The hosts discuss Richard Thaler and Kahneman/Tversky’s idea that people do not treat every dollar identically. Examples include paying more for shipping on a laptop than on a toothbrush and overspending on home furnishings after buying a house. Financial advice for young adults (Priority: 5/5): Levitt argues that younger people should spend more and save less because their earnings typically rise over time. Dubner pushes back, noting that this advice fits Levitt’s unusually strong earnings trajectory and may not generalize to most people. Choosing a hometown as an economic decision (Priority: 5/5): A listener asks how to choose where to live objectively. Levitt explains that economists think in terms of amenities, prices, and self-selection based on preferences such as schools, nightlife, nature, or proximity to work. City life, propinquity, and social spillovers (Priority: 4/5): Dubner defends urban living by emphasizing density, proximity, and idea spillovers, while Levitt notes that even small physical distance affects who people interact with and collaborate with. Lifestyle preferences and place selection (Priority: 3/5): Levitt and Dubner reveal their own preferences: Levitt prioritizes golf and schools, while Dubner values diners as inclusive public spaces. They also joke about using indicators like gay couples or amenities as proxies for desirable locations.

Key Arguments: Credit cards can make spending feel less painful than cash because the payment is delayed, which can increase willingness to pay. People use mental accounting: they mentally separate money by purpose or context, causing inconsistent spending decisions across similar purchases. Examples like shipping costs show that people often violate standard economic logic by paying more for high-ticket items than low-ticket items, even when the utility is similar. Young adults should not overemphasize saving if their future earnings are likely to rise substantially; they may be better off consuming more when young and saving later. Dubner argues Levitt’s advice is not universally applicable because it assumes a strong future earnings path that many workers do not have. Housing and location choices should be based on the amenities a person values and the prices they are willing to pay for them. Living near other people and institutions creates spillover benefits; distance materially shapes collaboration, friendships, and professional output. Lifestyle indicators like schools, diners, golf access, and neighborhood composition can serve as practical signals when choosing where to live.

Data Points: Credit card willingness to pay increase: up to 100% - Cited from a paper on the credit card effect, suggesting people may pay much more with credit than cash in genuine transactions. Shipping example cost: $30–$50 - Levitt says he might pay this extra amount to ship a laptop quickly but not a $20 toothbrush. House purchase example: $700,000 - Dubner uses this figure to illustrate how a $100,000 furniture bill can seem small after buying a house. Furniture/curtains add-on: $100,000 - Example of mental accounting after a large house purchase. Airport purchase threshold: $5 - Levitt says he stopped worrying about small airport purchases under this amount. Gas example: $60 - Used to illustrate the pain of paying when gas prices are visible at the pump. Listener age: 22 years old - The credit card question is posed by a 22-year-old quality assurance analyst. Education and earnings horizon: 25–30 years - Levitt says college graduates’ earnings generally rise for decades before declining.

Pivotal Quotes: "“It means I'm heavily confused right now.”" — Stephen Dubner: Opening joke explaining the acronym FAQ. "“I think so often young people don't consume as much as they should.”" — Steve Levitt: Levitt’s core argument that younger people should spend more and save less. "“Location really matters.”" — Steve Levitt: Levitt summarizes why where you live shapes your interactions, collaboration, and quality of life.

Implications: Listeners are encouraged to think less rigidly about money and place: spending is psychological, not purely rational, and location choices should align with real preferences, not social convention. The episode also suggests that advice should be tailored to life stage and earnings trajectory.
