The paper is based on 40 million observations of Uber tipping behavior, collected from four weeks of UberX rides in the summer of 2017, just after Uber rolled out in-app tipping. Uber had previously resisted building a tipping function into its app, arguing that quality of service and tipping often had little to do with each other, and saying that tips could push drivers to spend more time in wealthy neighborhoods, in search of bigger tips. In the past two years, the company says, drivers have received almost $2 billion in tips.

Her opinion is that “most tech-privileged parents should be less concerned with controlling their kids’ tech use and more about being connected to their digital lives.” Mimi is glad that the American Association of Pediatrics (AAP) dropped its famous 2x2 rule—no screens for the first two years, and no more than two hours a day until a child hits 18.
The researchers found that Uber riders were worse tippers than you might expect: Drivers were tipped in just 16 percent of rides, and just 1 percent of riders tipped on every trip. Sixty percent of riders never tipped at all. Male riders tipped 19 percent more often than female riders, and tipped 23 percent more overall. Counterintuitively, the more rides people took, the less likely they were to tip: Riders tipped nearly a quarter of the time in their first 15 trips, but by ride 275, tipped less than 10 percent of the time.
Because the tipping functionality had been introduced just before the study period, it’s possible Uber rider tipping behavior has since changed. The company declined to say whether there have been shifts in tipping since mid-September 2017.
The paper relies on detailed data about drivers, riders, and the rides themselves, including length, pickup time, and how many quick accelerations, hard brakes, and speeding stretches occurred during the trip.
Drivers’ characteristics and behavior appeared to affect riders’ tipping decisions. Female drivers, and especially younger female drivers, were tipped more often than male ones, especially by male riders. Those who accelerated quickly and braked hard also got slightly smaller tips, on average—about 50 cents less per tipped trip for the former, and about 1 cent less for the latter. But the age of the car didn’t matter much: Drivers with cars from after 2009 got about 1 cent more per trip than those with cars from before that year. (The researchers didn’t have data on the drivers’ or riders’ race.)
Drivers shouldn’t see the research as a how-to manual, says Bharat Chandar, one of the paper’s coauthors and a former Uber economist who is now studying for a PhD at Stanford’s Graduate School of Business. “On each given trip, the tip amount is a consequence of a lot of different factors that aren’t necessarily tied to quality,” he says.
Now for your latest installment of the on-again, off-again trade war between the US and China, we have President Trump blasting Beijing for reneging on commitments to clamp down on intellectual property theft, end forced technology transfers from US tech companies, and allow US companies greater access to the domestic Chinese market, including in cloud computing.
(Three of the paper’s four coauthors are former Uber employees. In general, Uber tends to enter into sensitive research agreements with teams that include at least one employee. The authors note that they worked with Uber product teams and management executives to design and implement the study, but a company spokesperson said that Uber does not censor findings.)
The paper is a peek into the dark heart of each Uber rider, a glimpse into the tipping decisions people make when no one is looking, and when they believe they may never see the tip-ee again. That behavior happens after Uber rides, sure, but also after DoorDash deliveries or TaskRabbit services.
