Have you ever wondered why some promotions seem irresistible, while others go unnoticed?
The answer may lie in behavioral economics.
This area mixes psychology and economics to understand consumer decisions.
Understanding these principles can be the key to increasing your sales.

Main points
- THE behavioral economics uses behavioral and economic sciences to analyze consumer decisions.
- Anchoring bias influences how prices are perceived by consumers.
- Loss aversion causes consumers to prefer avoiding losses rather than seeking equivalent gains.
- Confirmation bias affects the way messages are marketing must be structured.
- Prospect theory suggests that decisions are evaluated in relation to perceived gains and losses.
- Mental accounting indicates that consumers evaluate financial results subjectively.
- The sunk cost fallacy can lead consumers to make irrational decisions.
Introduction to Behavioral Economics
THE behavioral economics studies how thoughts, emotions and social influences affect our economic decisions.

Richard Thaler and Cass Sunstein are well-known names in this field.
They helped shape policies based on this area, especially during Barack Obama's presidency.
In 2010, the United Kingdom created the Behavioral Insights Team (BIT) to use behavioral science in policy.
In 2013, the US formed a team of nudge to apply these ideas.

The UK's Central Office of Information (COI) used behavioral economics in its campaigns.
They used psychology to change people's behavior.
Financial institutions and research agencies are also interested.
They want professionals to apply the principles of behavioral economics.
Professionals of marketing and consulting are increasingly interested in behavioral economics.
This is due to books like “Predictably Irrational” and “Nudge”.
A 2009 study by Biswas showed that people choose more options when they can customize them.
This shows how behavioral economics can influence consumer behavior.
The concept of framing shows that the way we present options affects perceived value.
For example, a final price of $1,500 looks better if the initial cost is $2,000 rather than $1,000.
Behavioral economics is still growing.
It is influencing business and politics. The union between economics and psychology has brought new ideas to various sectors.

Main Principles of Behavioral Economics
Behavioral economics was created in 1979 by Daniel Kahneman and Amos Tversky.
She studies how our daily choices are influenced by biases and perspective theory.
Understanding how we decide based on a reference point is one of the key points in this area.

For example, when buying used cars, the initial price is a reference point.
This causes buyers to see lower-than-initial prices as great deals.
This phenomenon helps explain why early information can change our future decisions.
THE perspective theory shows that losses weigh more than gains.
This leads to decisions that don't make sense. availability heuristic is also important.
She says that people judge probabilities by the experiences they remember most easily.
Another common bias is optimism. People tend to think they will succeed more than they actually do.
THE framing effect shows that how we present information can greatly change the final decision.
| Principle | Example |
|---|---|
| Decision-making biases | Ostrich Effect: tendency to ignore negative information. |
| Reference point | Starting price on used car sales. |
| Prospect theory | Losses have a greater impact than gains. |
| Availability heuristic | Judgment based on easily remembered experiences. |
| Optimism bias | Overestimation of the chances of success. |
| Framing effect | Presentation of information influences decisions. |
A study on organ donation showed that allowing donation by default greatly increases donation rates.
Amazon, for example, did this with “1-Click.” This shows that simple choices can make a big difference.
Most of the time, we make decisions with system 1.
It is fast, intuitive and emotional. Understanding this helps us see how biases and prospect theory influence our daily choices.
Applications of Behavioral Economics in Marketing
THE influence of behavioral economics node marketing grew a lot.
This happens because we better understand what motivates people to make decisions.
For example, the loss aversion shows that losing something hurts more than gaining something new.
This idea helps to create more effective advertising campaigns.
They can reach the audience more efficiently.

A Prudential campaign drew attention to the fear of loss.
She asked, “What would you do if you couldn’t work tomorrow?” This made many consumers want more life insurance.
In appliance stores, it helps to talk about what the customer would lose by not exchanging an old appliance.
For example, talking about the increase in the electricity bill and the risk of failures.
Apple also uses this strategy, showing what the consumer loses by not having an iPhone.
A study in the telecommunications sector showed that talking about what customers would lose by switching providers helps.

This includes special benefits and priority technical support.
This approach has greatly reduced cancellation rates.
| Aspect | Practical Example | Result |
|---|---|---|
| Loss aversion | “What would you do if you couldn’t work tomorrow?” – Prudential | Increase in insurance sales |
| Replacing household appliances | Emphasize increased costs and risk of failures | Increased sales |
| Marketing emotional and rational | Loss of the iPhone experience | Increase in purchasing decisions |
| Customer retention in telecommunications | Loss of special benefits when switching providers | Reduction in cancellation fees |
Using these principles can help your business attract more customers.
And also keep the customers you already have. Understand the influence of behavioral economics brings valuable insights.
These insights transform business strategies. marketing into powerful tools for success.
Neuroscience and Behavioral Economics
Exploring the relationship between neuroscience and behavioral economics is essential.
This includes the neuroscience in marketing.
Studies show that biology influences our decisions in complex ways. Neuroscience helps us understand these influences.
Since 1990, over 900 studies in PubMed have discussed decisions and the brain.
This research is fundamental to understanding how we make decisions.
The discovery of dopamine was a major breakthrough in Cognitive Neuroscience and Neuroeconomics.
Genetics and neurobiology affect our choices.
But we're still figuring out how much. Recent studies show the role of the limbic system in our social interactions.
Below, we present interesting data related to these discoveries:
| Study | Discovery | Impact |
|---|---|---|
| Glimcher and Fehr (2014) | 900+ publications on decision making and the brain | Solid basis for further studies |
| Kahneman and Tversky (1979) | Prospect Theory | Context as a crucial factor |
| von Neumann and Morgenstern (1944) | Game Theory | Limbic system and social interactions |
| Current research | Genetic/biological factors | Impact on decision making |
THE neuroscience in marketing opens up new possibilities.
It helps to create more effective strategies and also to better understand how we make decisions.
Case Studies in Behavioral Economics
The field of case studies in behavioral economics shows how we make decisions in different situations.
For example, recent research has applied Kahneman and Tversky's (1979) prospect theory.
She analyzed how Economics and Administration students at a Brazilian federal university make financial choices under uncertainty and risk.
This study, with 27 questions, showed that students still make choices influenced by emotions and cognitive biases.
Loss aversion and optimism are examples of this.
Prospect theory helped to understand these “irrational” behaviors in investments.
Another study, by Rosales-Pérez et al. (2021), showed that emotional intelligence affects financial decisions.
Deficiencies in empathy and emotional regulation can undermine these choices.
This finding is important, as prospect theory is still little studied in developing countries, such as Latin America.
Understand these case studies in behavioral economics helps you see how emotions and biases affect our financial choices.
This analysis not only improves our understanding of behavioral economics. It also provides tools to improve our decisions at work.
Implementing Behavioral Economics in your Company
Adopting behavioral economics strategies can change how your company relates to employees and customers.
Many companies are appointing a Chief Behavioral Officer. This shows that this practice is growing.
EY-Parthenon has shown that two to three month projects can bring great results.

It is essential to involve senior management. But it is not necessary for everyone to be an expert. Setting clear goals helps a lot.
To begin with, it may be helpful to start with a specific team.
Nudging, small interventions, can increase employee engagement by up to 30%.
This when applied correctly.
Effective feedback is also crucial. It can increase job satisfaction by up to 25%.
Choice architecture can increase adherence to healthy options by up to 40%.
Nubank uses a simple design to help control spending.
Real-time notifications show the impact of behavioral design.
