The Economist has an article discussing the ride share industry.  They pointed out that ride share companies engage in price gouging when demand for their services is high:

This digital twin, one of the most sophisticated of its kind, allows Uber to adjust its operations in real time. Annoyed passengers may think that this enables the firm’s “surge pricing”, when fares suddenly spike to balance ride demand and driver supply. This is partly true. But the more immediate and more positive effect is that the digital twin allows for up-to-the-minute route optimisations through ever-changing city traffic.

(Price gouging is generally defined as a situation where companies set the price above the customary level in order to prevent shortages from occurring.)

The taxi industry provides a nice test of the theory that consumers don’t like price gouging.  Prior to the advent of ride sharing, the NYC taxi industry was regulated by the government, which set a standard price.  As a result, it was extremely difficult to find a taxi during peak periods, when demand exceeded supply at the regulated price.

Ride share companies decided to adopt surge pricing during periods of high demand, in order to prevent shortages.  As you can see, they’ve grown to dominate the NYC taxi market:

It would not surprise me if a poll showed that most Americans oppose price gouging.  But economists typically put little weight on polls; we are more interested in how people behave, that is, their revealed preference.  And at least in the NYC taxi market, it seems that consumers prefer price gouging to a stable regulated price.

One possible objection is that it is not the price gouging that they like, rather it’s the quick and reliable availability of the ride share cars.  But those are merely two sides of the same coin.  Flexible pricing is both a necessary and sufficient condition for assuring that quantity supplied equals quantity demanded.  You cannot have one without the other.  Thus regardless of what consumers might say, it seems to be the case that they actually do prefer a regime with price gouging over a regime with shortages.

PS.  After beginning this post, I discovered a John Cochrane post that makes some of the same points.
