Definition
Surge pricing is a dynamic pricing technology in which an algorithm raises prices in real time when demand for a service suddenly piles up in one area. Companies describe it as a device that quickly connects people who want the service with providers willing to work, so the market does not freeze up, not just as a way to earn more profit. But critics say it pushes the burden onto users.
Why Do Fares Jump on Rainy Nights?
You may have opened a ride-hailing app in a busy nightlife district on a Friday night and seen the fare far above normal. On services like Uber abroad, fares can climb to 1.5 times the usual price when it rains, and sometimes to 2 times or more. In Korea, regular taxis run on a set meter fare. So instead of the fare itself, a capped call fee goes up and down with demand.
When far more people want a ride than there are people to give rides, a computer program raises the price on the spot, using real-time data. This technology is called surge pricing. When it rains, or when the last subway is about to leave, the number of people wanting a taxi can swell to thousands in no time. But the number of cars on the road is limited.
If everyone paid only the usual base fare, the app would jam up. Lots of riders would stand on the street in the rain, staring at a screen that never finds them a car. When the price goes up, riders who do not need a taxi right now turn to the bus or subway instead.
In the end, cars go first to the riders willing to pay more, and the rush of demand gets spread out. That is the principle at work. But the person who can pay more is not always the person in the biggest hurry, so debates about fairness follow.
It Is Not Just About Cutting Down Customers
When riders see prices rise, it can feel like the company is slyly squeezing out more money. But the other key goal of this technology is to pull workers who were resting at home, or who were somewhere else, to that spot.
Say a notice pops up on a driver's or delivery rider's app: "Fares are 1.8 times higher than usual." Drivers who were getting ready to finish for the day, or who were in a quiet part of town, head over to that area. That is because it promises workers something clear: more income.
So surge pricing uses price as a strong signal, a way to quickly draw scarce supply to where it is needed. If fares stayed the same, drivers would have little reason to drive into rainy traffic jams or crowded nightlife streets.
Once the added supply and the reduced demand meet and balance out, the fare slides back down to its usual level. The price moves flexibly and keeps the see-saw of supply and demand level in real time.
A Bit More Precisely
To be more precise, surge pricing is not a person sitting in an office changing price tags by hand. A carefully built AI algorithm splits a city map into hundreds of small zones. It keeps comparing the number of ride requests in each zone with the number of cars on the road, and calculates from there.
It is also known to use things like past trip records, the weather, and the ending times of big nearby stadium games or concerts to predict demand. Using machine learning, the system can foresee how many riders will flood in a few minutes from now, and raise prices ahead of time.
But prices have also shot up in emergencies such as heavy snow, terrorist attacks, and big fires. This has drawn ethical criticism that it takes advantage of the fear of vulnerable riders. Charging high fares to people trying to escape an emergency goes against the public interest.
So some companies set a cap so fares cannot climb without limit, or have policies that limit surcharges once a disaster is declared. In some countries, the size of the surcharge is capped by law, as with taxi fares.
Common misconceptions
Surge pricing is a trick companies use to give users a hard time and make huge profits.
Companies and the economists who support the practice say it is a device that keeps the market from freezing up. Higher prices push back the demand of people who can wait longer, and the extra pay draws more drivers to the area, they argue. On the other hand, critics say it only adds to the burden on users in a crisis, so opinions are split.
Where you meet it
You open a ride-hailing app on a rainy night and see a 1.5 times surcharge on the usual fare.
Right after a big concert or baseball game ends, delivery fees or taxi call fees around the venue go up for a while.
In one sentence
Surge pricing is a technology in which an algorithm raises fares in real time when demand spikes, to spread out demand and draw in supply.
