Behavioral Economics in Practice: How Psychological Factors Shape Financial Decisions

This is an article ‘Behavioral Economics in Practice: How Psychological Factors Shape Financial Decisions’ by Marc Primo.


Behavioral economics, at its core, mainly deals with how psychology affects the way we make economic decisions. How we buy our preferred products, align our savings with our spending, or even practice delayed gratification for better future gains all have to do with behavioral economics.


However, on the flip side of the coin, little do consumers know that companies utilize the right set of data to determine and predict how their target market will behave towards their products or competitors. The important thing is that a review of the right data gains both companies and us, the consumers, a win-win situation when it comes to offering and purchasing today’s products.



Unlike traditional economic theory, which assumes that individuals are always rational and strive to maximize their own self-interest, behavioral economics claims that humans are often irrational and often influenced by myriad cognitive biases. This fascinating fusion of psychology and economics has given us a deeper understanding of how people really behave when it comes to money and markets.


Let’s dive a little deeper into how our behaviors and ideas affect the way we consume goods and our personality in the process:


The Cognitive Biases Behind Our Financial Decisions


As it turns out, most people are not the perfectly rational creatures we thought we’d be. At least, classical economics once assumed that idea. However, our decisions in current economic times tell experts that we are influenced by a plethora of cognitive biases.


Enter the theory of Loss Aversion. People often feel the pain of a loss more intensely than the pleasure of a comparable gain. This psychological phenomenon was extensively studied by two pioneers in the field of behavioral economics, Daniel Kahneman and Amos Tversky. In their groundbreaking 1979 paper, “Prospect Theory: An Analysis of Decision under Risk,” they found that individuals place approximately twice as much weight on potential losses as potential gains when making decisions. This means that the fear of losing $100 might deter someone from taking a bet, even if they have an equally likely chance to gain $200.


Behind this thought, there’s also overconfidence, which can make us believe that we know more than we do. Robert Shiller, who won a Nobel Prize for his work in behavioral economics, pointed out that overconfidence can lead to speculative bubbles in financial markets. Shiller's book "Irrational Exuberance" delves into how investor overconfidence contributed to the dot-com bubble of the late 1990s and the housing bubble in the mid-2000s. With that, experts also discovered that we all have the tendency to anchor too heavily on the first piece of information we come across, especially when making financial decisions. For example, if you first see a jacket priced at $500 and then see a similar one for $250, you might feel that the second jacket is a bargain, even if it’s not worth its price in terms of quality and material.


Real-world Implications of Behavioral Economics


Digging deeper into the human psyche vis-a-vis how we deal with finances, we find that the impacts of these biases can be seen in various areas— from individual investment decisions to broader financial market trends.


One of the most well-documented implications of behavioral economics in personal finance is the “status quo bias.” This bias describes our tendency to stick with our current situation, even when a certain degree of change might be beneficial in the long run. This might remind you of the inertia seen in 401(k) savings. One study for the Quarterly Journal of Economics at the start of the new millennium found that when employees were automatically enrolled in a 401(k) plan, participation rates surged compared to when they had to opt in themselves.


The same can be somehow said in financial markets. Since broader markets are not immune to these psychological quirks, herd behavior (or instances when investors follow what others are doing rather than their own analysis) often leads to market bubbles and crashes. The infamous Tulip Mania in 17th-century Holland is often cited as a good case study of this phenomenon. Here, prices for tulip bulbs skyrocketed not because of any inherent value in the bulbs but largely due to social influences and the fear of missing out. This, of course, eventually led to a spectacular market crash.


Recent behavioral insights have also shaped private and public policy in recent years. In the UK, authorities set up its Behavioural Insights Team back in 2010 to apply behavioral science to its public services. One of their notable interventions was to boost tax payment rates. By changing the wording in a letter to emphasize that the majority of people pay their taxes on time, they leveraged the 'norms' and saw a significant increase in compliance.


Harnessing Behavioral Economics


Given all these theories, studies, and insights, what does that tell us about how today’s consumers react to commercial offerings? One thing that’s for sure is that once we understand the underlying psychological factors at play can help finance professionals and individuals make better decisions.


Finance savants have long practiced careful awareness of these biases. By designing products and services that cater to real human behavior, such as "robo-advisors," which are automated digital platforms that provide financial advice or investment management online, they can better incorporate behavioral economics principles to nudge users towards wiser investment choices.


That goes without saying that, for the common coin saver, awareness should always be the first step. Knowing that you're prone to certain biases can help you take a step back and re-evaluate your decisions. For instance, if you're hesitant to diversify your investments because of an attachment to a particular stock, recognizing this can help you reassess whether that attachment is clouding your judgment.


Constant Study and Personal Review Always Comes Next to Awareness


Behavioral economics pulls back the curtain on the mental machinations that drive our financial choices. It reveals a world where emotion, psychology, and irrationality play a significant role. But this isn't a cause for despair. By understanding these psychological factors, we can better navigate our financial futures and potentially harness our biases for our benefit.


Whether you're a finance student, a professional, or just someone interested in making more informed money decisions, diving into the world of behavioral economics can provide invaluable insights.
