Question

Founded in 2009 by Travis Kalanick, Uber provides transportation service in U.S.,
European, and Asian cities. In the year 2014, its gross revenues were $2.957 billion, net
revenue after commissions and incentives, $495 million, cost of revenue, $400 million,
operating expenses, $661 million, for EBIT of -$565 million.
The original Uber model of operations was for the driver to use her/his own vehicle and offer
services as and when they liked. The Uber webpage to drivers emphasizes, “Drive your
own car using the Uber Partner app to find riders in your area. Set your own schedule. Get
paid weekly.” More recently, Uber has arranged for drivers to rent cars so as to provide
Uber services.
Uber clients book and pay for rides through the smartphone. After each ride, the Uber client
rates the driver on a scale from 1 to 5. If a driver’s rating falls below a particular level, Uber
discontinues her/him from offering the service. Uber also allows drivers to rate clients.
In January 2015, Uber extended fare cuts from the largest U.S. markets to 48 more
cities. Uber asserted that the lower fares would benefit clients and drivers: “with the
increased demand, drivers’ income goes up as well. More demand turns into significantly
more efficiency for the driver, more trips for every hour, and more earnings for every hour
on the road”.
By contrast with Uber, whose drivers provide service with private cars, the Chinese
services, Didi Dache (backed by Tencent) and Kuai Di Dache (backed by Alibaba) are
smartphone-based applications to book taxis. In 2015, faced with competition from Uber
(backed by search engine Baidu), Didi Dache and Kuai Di Dache merged. Following the
merger, they continue to operate as separate services.
(a) What economic inefficiencies does the original Uber operating model exploit? How
does your answer change for drivers who rent cars to provide Uber services?
Compare the economic inefficiencies addressed by Uber vis-à-vis Didi Dache.
(b) What economic concept relates a cut in prices to an increase in demand? Explain
how to use this concept to calculate the change in revenue from a 1% cut in prices.
In Chicago, the reduction of fares by 23% led to 12% increase in revenue. What do
these data imply about the concept in (b)?
(c) On a figure with dollars per hour on the vertical axis and hours of labor supplied on
the horizontal axis, please sketch the driver’s marginal benefit from providing labor.
Note: If the driver supplies more hours, she raises the probability of getting work, but
at a diminishing rate.
(i) Explain how a reduction in the fare affects the marginal benefit from providing
labor. Consider both the direct effect of the fare and the indirect effect (lower
fare attracts more customers and raises the probability that the driver gets work).
(ii) From a driver’s viewpoint, what is the optimal quantity of labor to supply?

Answer 1

a)charging a price below the optimal level to get a higher market share. the drivers who rent cars have to pay an additional amount which increase the cost for them above others. two strong competitors collaborated in order to take uber out , may exploit the code of conduct of market by charging unfair prices .

b) you in order to grab the extra market share would decrease the price of the good . its the elasticity of price concept and law of demand . revenue would increase as with price decrease the quantity demanded would increase. this implies that by the rate at which the price falls, the demand increases by half that rate.
