As previously noted, about two thirds of Uber driver-partners work either full-time or part-time on another job. Therefore, it is not surprising that most drive with Uber part- time. The platform is conducive to a wide range of work schedules, and this is supported by the fact that there is little discernible relationship between hourly earnings and hours spent on the platform. Table 3 illustrates this pattern for October 2015 for uberX drivers, which we selected as a month after Uber’s summer fare cuts and before the holiday season to represent more normal market conditions. The table reports earnings per hour with the app on, broken down by amount of time spent driving per week in the six largest markets where Uber operates, and for the 2014 BSG markets combined. Reported earnings here are net of Uber’s fees but do not adjust for driver-partners’ expenses, which we try to estimate below.20 We also emphasize that the hours measure is an imperfect and probably overstated measure of hours worked, as drivers can have an app for another ride-sharing platform on while their Uber app is on, and they can conduct personal tasks while the Uber app is turned on.

This omission causes us to slightly understate drivers’ earnings. 21 Trimmed one-percent means were selected instead of medians because the results were similar and because it is more appropriate to average trimmed means across cities than medians to derive an aggregate measure. 20
