For taxi drivers, there’s now a reason to enjoy sunny days even more: Sunshine drives up cab tips, according to research published this month. The study tracked weather and nearly 14 million taxi rides in New York City over a 10-month period and found that a shift from a dark sky to full sunshine was linked to a 0.7% increase in tipping. That’s no big deal for one ride, but over dozens of trips a day, it adds up—accounting for an estimated daily increase of $17,466 in cab tips citywide.
With taxi trips being a fairly standardized experience--unlike restaurants, which range dramatically in food quality and atmosphere--the researchers argue that taxicabs are a great model for understanding general tipping behavior, a practice that makes up billions of dollars for the U.S. economy. Researchers couldn’t definitively say why sunshine drove up tips, but suggested it was linked to better moods, which have previously been shown to improve with sunlight.
