Behavioral Economics with Fexingo: Decision Making, Bias, and How People Really Spend
What really drives the way people spend, save, and invest? Behavioral economics challenges the textbook assumption of the rational actor by revealing the systematic biases and mental shortcuts that shape every financial decision. In this show, Lucas and Luna sit down at the research library to dissect the experimental evidence, from Kahneman and Tversky's prospect theory to Thaler's nudge framework, and test those findings against real-world pricing, marketing, and policy design. They walk through specific studies — the endowment effect in housing markets, the sunk-cost fallacy in subscription pricing, the framing of credit-card interest rates — and ask what those experiments imply for a consumer choosing a mortgage or a CFO setting a price. Lucas brings the investigative journalist's rigor, pressing for the exact sample sizes, replication rates, and alternative interpretations; Luna pushes back with the practitioner's instinct, asking whether a bias that shows up in a lab actually translates to a shopping cart on Amazon.

The hosts unpack why this bias dr
The Insulation Effect Why a Big Bill Feels Smaller
Why does a $10,000 roof feel less painful than a $400 car repair? Because your brain spreads large, infrequent costs over time, making them feel smaller than they are.

They examine a real-world case: a Swiss watchmaker's limited edition that sold out in hours, despite a price tag
Why Your Brain Treats a Freebie as a Gift
In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore the 'free gift effect' — why receiving something for free, even when it's part of a promotion, triggers a sense of obligation and gratitude that changes how we evaluate the giver. They dig into a 2019 study from the Journal of Marketing that found free gifts increase purchase intent by 23 percent, even when the gift's val

They start with a concrete example: a $200 jacket marked down to $120. Lucas explains the concept of transaction utility, a term coined by Richard Thaler, where the perceived deal itself becomes part of the value. They discus
The Hidden Cost of Mental Accounting in Your Budget
In this episode, Lucas and Luna dig into mental accounting—the psychological quirk that makes us treat money differently depending on where it comes from or what jar we put it in. They anchor the conversation with a real-world example: how a $1,000 tax refund often gets spent on a splurge, while the same amount earned from a paycheck gets saved.

Why Your Brain Treats a Windfall Differently Than a Paycheck
In episode 152 of Behavioral Economics with Fexingo, Lucas and Luna explore the psychology of windfall gains: why a surprise bonus, a tax refund, or a gift card feels different from regular income, and how that difference changes what we do with the money. They dive into the classic 'house money' effect from experimental economics, the mental accounting research of Richard Thaler, and a striking r
The Endowment Effect in Reverse
In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore the 'endowment effect in reverse' — why letting go of what we own feels so painful that we often hold onto things that actively cost us money.

Why Your Brain Treats a Free Trial as a Trap
In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore why free trials feel like a gift but often end up costing us more. They drill into the specific psychology of the 'trial-to-paid conversion' — why we sign up, why we forget to cancel, and why companies design the cancellation process to be as painful as possible. Using the example of a popular streaming service and a gym
How Rebates Make Us Overpay
In this episode, Lucas and Luna explore the rebate trap: why a promised cash-back deal makes us spend more than we otherwise would.

The hosts discuss the endowment effect, the contrast effect, and the pain of paying, explaining why a ten percent discount for members fee
Why Your Brain Treats a Subscription as a Sunk Cost Trap
In this episode of Behavioral Economics with Fexingo, Lucas and Luna dig into the psychology of subscription fatigue. You sign up for a streaming service, a gym, a software tool—and then you never use it, but you keep paying. Why? It's not just laziness. It's a mix of the sunk cost fallacy, loss aversion, and the way our brains treat recurring charges as invisible. They unpack the research, includ
Why Your Brain Treats a Recurring Bill as Invisible
In this episode, Lucas and Luna explore the behavioral economics of recurring bills — why a gym membership or streaming subscription that auto-renews each month feels less painful than a one-off purchase of the same amount, and how that 'invisibility' quietly shapes household budgets. They anchor the discussion in a concrete case: the rise of subscription fatigue and the growing number of consumer
Why Your Brain Treats a Used Car as a Better Deal
Why does a slightly scuffed Toyota feel like a bargain while a pristine one feels overpriced? In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore the 'used car effect' — a quirk of mental accounting that makes previously owned goods seem more valuable, not less. They break down the psychology behind the 'ownership premium', why the first owner's loss is the second owner's
The IKEA Effect and Why We Overvalue Our Own Work
In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore the IKEA effect—the cognitive bias that makes us place a higher value on things we've helped create.

The Pain of Paying How Credit Cards Trick Your Brain
In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore the 'pain of paying' — the psychological discomfort we feel when parting with money. They anchor on a landmark 1998 study by Prelec and Simester which found that people are willing to pay up to 100% more for the same item when using a credit card compared to cash. The discussion unpacks why credit cards decouple the pleas
How the Endowment Effect Makes You Overvalue Your Possessions
In 1990, economists handed half a classroom of students a coffee mug and asked them to name a selling price. The others stated a buying price. Sellers demanded a median of $5.25; buyers offered just $2.25. That two-to-one gap is the endowment effect — our tendency to value what we own more than what we don't. This episode unpacks why ownership changes perceived value, from mug experiments to home
How the First Number You See Sets the Price Youll Pay
Why does the first price you see for a product or salary become the benchmark for everything else? Lucas and Luna dive into the anchoring effect, the cognitive bias discovered by Kahneman and Tversky that explains how an initial number—even a random one—can warp our judgment. They explore a classic experiment where a spinning wheel of fortune influenced guesses about UN membership, then trace anch
Why More Choices Make Us Buy Less
Back in 2000, psychologists Sheena Iyengar and Mark Lepper set up a tasting booth in a California grocery store. On some days, they offered 24 varieties of jam. On others, just 6. The display with 24 jams attracted more customers—but only 3% bought. The display with 6 jams? 30% bought. That 10x conversion gap is the paradox of choice in action. In this episode of Behavioral Economics with Fexingo,
Why Your Brain Prizes Instant Gratification Over Future Wealth
Ever wonder why saving for retirement feels so hard, even though you know it's smart? It's not just willpower — it's how your brain discounts future rewards.

Why Your Brain Treats a Subscription as a Sunk Cost Trap
In this episode of Behavioral Economics with Fexingo, Lucas and Luna dive into the psychology behind why we stick with subscriptions we barely use. They explore the concept of sunk cost fallacy—how our brains treat a monthly fee as a loss we need to justify by continuing the subscription, even when it no longer provides value. Using the example of a $10 monthly gym membership, they discuss real-wo
Why Your Brain Trusts a Handshake More Than a Contract
In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore the behavioral principle of 'social over legal' — why people trust a verbal deal more than a written one.

Why Your Brain Treats a Guarantee as a Decision Shortcut
Episode 120 of Behavioral Economics with Fexingo explores the psychological power of satisfaction guarantees. Lucas and Luna examine the classic case of L.L.Bean's legendary return policy, how it built decades of customer trust, and why the company's 2018 decision to limit returns sparked backlash—not because people wanted to abuse the policy, but because the guarantee itself served as a cognitive
Why Your Brain Treats a Default Option as a Decision Already Made
In behavioral economics, the default effect explains why people overwhelmingly stick with pre-selected options — even when switching costs are zero and a different choice would save them money or improve their outcome. Lucas and Luna drill into the most powerful real-world example of the past decade: automatic enrollment in retirement savings plans. They walk through the data from Richard Thaler a
Why Your Brain Treats a Price Tag as a Memory Anchor
In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore how the first price you see for a product—called an 'anchor'—shapes every subsequent price judgment, even when you know it's arbitrary. They dive into a 2003 field experiment by economist Dan Ariely where he asked students to write down the last two digits of their Social Security numbers, then bid on luxury goods. Studen
Why Your Brain Treats a Subscription as a Sunk Cost Trap
In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore why subscriptions are so hard to cancel—even when we barely use them. They anchor the discussion on a 2025 study from the University of Chicago that found people who signed up for a $10 monthly streaming service were 40% less likely to cancel after three months, even when they rated the content as 'poor' or 'fair.' The ho
The Endowment Effect Why You Overvalue What You Already Own
Why do we demand more to sell a coffee mug than we'd pay to buy it? In this episode of Behavioral Economics with Fexingo, Lucas and Luna explore the endowment effect—a cognitive bias that makes people overvalue what they already own. Using the classic 1990 Kahneman, Knetsch, and Thaler mug experiment, they break down how loss aversion and ownership distort our sense of value. Then they zoom out to

In this episode, Lucas and Luna explore the behavioral economics concept of 'mental accounting' — specifically how the brain categorizes windfalls as 'play money' and what that means for your spending and saving decisions. They anchor the discussion in a real-world example: the 2021 Child Tax Credit ad
Why Your Brain Treats Poverty as a Cognitive Tax
In this episode, Lucas and Luna explore the concept of 'cognitive scarcity' — how financial stress actually reduces IQ scores and decision-making capacity.

They break down the psychology: the cap becomes a license to consume up to it
Why Your Brain Treats a Frequent Flyer Mile as Real Money
Episode 110 of Behavioral Economics with Fexingo: Lucas and Luna explore the endowment effect in loyalty points—specifically how Delta Air Lines' 2023 SkyMiles devaluation triggered an emotional response more intense than a cash price hike. Drawing on Nobel laureate Richard Thaler's mental accounting and the 'pain of paying' research by Drazen Prelec and George Loewenstein, they walk through why t
Why Your Brain Treats a Rebate as a Windfall
Why do we spend rebate money more freely than our own cash? In episode 109 of Behavioral Economics with Fexingo, Lucas and Luna examine the 'rebate windfall effect' through the 2009 Cash for Clunkers program. That $3 billion stimulus offered up to $4,500 per trade-in, but consumer data showed people treated the rebate as found money—not a discount. Over 690,000 transactions happened, yet 40% of pa
Why Your Brain Treats a Price Increase as a Quality Signal
Episode 108 of Behavioral Economics with Fexingo. Lucas and Luna explore the Veblen effect — why higher prices can actually increase demand for certain goods.

They discuss signaling theory, the difference between luxury and necessity goods, and how brands like Rolex and Supre
Why Your Brain Treats a Round Number as a Trust Signal
This episode explores the behavioral economics of just-below pricing and round numbers. Lucas and Luna examine why we intuitively trust round prices like $10 more than $9.99, and how that trust shapes spending decisions.

They discuss why the effect is strongest for haptic-oriented categories like a
Why Your Brain Treats a Sale as a Loss Aversion Trap
Episode 92 of Behavioral Economics dives into the psychology of sales. Lucas and Luna unpack a 2024 experiment showing that consumers actually feel a subtle loss when they see a '50% off' sign — because the brain frames pre-sale price as a forfeited reference point. They explore why a 40% discount feels better than a 50% one when the original price is high, and how retailers use 'sale' framing to
Why Your Brain Treats a Flat Fee as a License to Consume
This episode explores the 'flat-rate bias': why paying a fixed fee for unlimited access — whether at a gym, a streaming service, or a buffet — makes people consume more than they would with a per-use price, even when they'd be happier paying per use.
