Why do people leave tips? According to new research, the answer comes down to two main motivations. Some customers tip as a pure reward for good service. Some people tip because they feel pressured to conform to social norms.
That difference is important. Customers who truly value your service often leave more than their usual amount. People who are primarily motivated by social expectations tend to match the average tip, no matter how much. Over time, this dynamic can cause tipping rates to rise steadily in places where tipping is common.
Research published in business administration A study by Dr. Ran Snitkowski of Tel Aviv University’s Koller School of Management and Professor Lawrence Debo of Dartmouth College’s Tuck School of Business uses a theoretical model to better understand this behavior.
“Overturning is a phenomenon that is difficult to explain using classical economic tools,” Dr. Snitkowski explains. “A ‘homo economicus’ who is only interested in his own material wealth has no reason to tip once a service has been rendered. Researchers have suggested in the past that tipping guarantees better service in the future, but this does not explain why you would tip even if you were sure you would never encounter that particular service provider again. For example, you might tip a taxi driver in New York even though there is virtually no chance you will ever meet him again. And even if we do, they probably won’t remember us.Whether or not this is true, tips give servers an incentive to provide better service, so selfish customers want to tip others and maintain good service quality while avoiding their own expenses.The bottom line is that to understand this phenomenon deeply, we need to consider psychological and behavioral considerations.
Tipping is big business. A recent study reported by USA Today found that the average American spends nearly $500 a year on tips at restaurants and bars. Tipping revenues in the United States collectively generate more than $50 billion annually and are a major source of income for millions of workers.
Behavioral economics and game theory models
To dig deeper, the researchers used tools from game theory and behavioral economics to build a mathematical model.
“We used mathematical models and tools from game theory and behavioral economics to understand the motivations behind the chips,” says Dr. Snitkowski. “I entered into this model two main reasons why people report tips: first, to show gratitude to the service provider, and second, conformity, to do the same as others. The first reason is related to my personal evaluation of the service I received or the server-customer interaction, and may stem from a desire to reward the server for doing their job or showing empathy to the server.2 The second reason is related to my own perception in society, i.e., my interactions with other customers, i.e. I can distinguish between: “viewers” and “conformists.” ”
Their findings suggest that in societies with stronger social pressure, the average tip increases over time. When people feel a strong need to follow the crowd, they are more likely to match or exceed prevailing norms.
“This process is essentially driven by the evaluator elevating the fitter, not the other way around,” Dr. Snitkowski says. “This may explain why tipping rates in the United States went from about 10% a few decades ago to closer to 20% today. People who value service are willing to tip much higher than average, while those who want to follow convention tend to tip more than average. In addition, the increase in tipping rates may also reflect growing economic inequality, a hypothesis proposed by another researcher at Tel Aviv University, Professor Yoram Margaliot of the Buchman School of Law, and supported by our model.
Does tipping actually improve service?
The team also investigated whether the chips could actually improve server performance. Their model shows that while hints can encourage extra effort, their effect is limited.
Many customers tip based on social norms rather than quality of service, so servers often receive a standard percentage regardless of performance. If that happens, the incentive will be weakened.
“If a server knows that most customers are conformists, they will tip the customary amount anyway, so there is little reason to make the extra effort. This is actually the situation in countries like the United States. In a hypothetical world where all customers were appreciators and unaffected by each other’s tipping rates, tips would be a stronger incentive. On the other hand, in a world where tips only reflect appreciation, companies may conclude that customers are willing to pay more for the service experience and charge more up front. ”
Economics of tip credit laws
The researchers also analyzed the “tip credit” system used in most U.S. states. Under this policy, employers can pay tipped workers less than the standard minimum wage and count the difference as tips. For example, if the minimum wage is $8 an hour and the tipped wage is set at $3, the employer can pay $3 directly and cover the remaining $5 in tips. If tips do not earn a worker more than $8 an hour, the employer must make up the shortfall. If tips increase their income by more than $8, workers keep the additional amount.
“We find that higher tip credits allow companies to lower prices because they rely more on tips to fund their workforce,” Dr. Snitkowski says. “As a result, supply increases and more customers can be served. This suggests an element of economic efficiency, but the efficiency in this case came at the expense of the individual server’s revenue. So essentially, a tip credit is a mechanism that allows an employer to carve out tips that ostensibly belong to the server and use them to pay wages.”
The social cost and complexity of chips
Snitkowski admits that he approached the chip study with some skepticism.
“I approached this study with some bias. I personally don’t like this practice and wanted to understand what was causing it. First of all, tipping puts customers in an uncomfortable position. Research shows that tipping can encourage sexist behavior towards female servers, and that women may refrain from setting boundaries to avoid losing tips. Other studies have shown that people are more generous in tipping when the server is of the same ethnicity as themselves. Although it is easy to find good reasons to abolish tipping, this practice also has some positive effects, making it a complex phenomenon. Ultimately, tipping allows people to pay more for services and thereby provide services to others, although this effect is very limited. Century business owners are now able to offer better services, including online reviews and in-house cameras.”
