Behavioral Economics with Fexingo: Decision Making, Bias, and How People Really Spend

Fexingo 106 Episodes Oct 13, 2026

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 Zero Price Effect And Free Goods

The Power of Zero in Consumer Pricing
The Power of Zero in Consumer Pricing Oct 3, 2026 8:35 We explore the zero price effect, where removing a cost creates irrational demand spikes that defy basic economic logic.
