How a 99-Cent Price Taps Your Left Brain
from Behavioral Economics with Fexingo: Decision Making, Bias, and How People Really Spend · host Fexingo
Episode 38 of Behavioral Economics with Fexingo digs into the left-digit effect — why a $4.99 price feels dramatically cheaper than $5.00. Lucas and Luna explore the 2011 University of Chicago study showing that reducing a price from $5.00 to $4.99 boosted sales by 24%, while an equivalent 1-cent drop from $5.00 to $4.99 had no effect. They discuss real-world applications at retailers like J.Crew and the psychology of how our brain reads prices left to right. This episode also touches on William Poundstone's book 'Priceless' and why 9-ending prices are so sticky in marketing. No fluff, just the concrete science behind why your brain treats 99 cents as a bargain. #BehavioralEconomics #LeftDigitEffect #PricePsychology #9EndingPrices #CharmPricing #ConsumerBehavior #CognitiveBias #MarketingStrategy #RetailPricing #Poundstone #UniversityOfChicago #SalesBoost #DecisionMaking #Economics #FexingoBusiness #BusinessPodcast #Bias #PricingScience Keep every episode free: buymeacoffee.com/fexingo
