The Rise Of Behavioural Economics In The 21st Century
The Rise Of Behavioural Economics In The 21st Century What Is Behavioural Economics? ChaptersBehavioural FinanceKey Figures in Behavioural EconomicsFind Out More By Reading Popular Behavioural Economics BooksBehavioural economics is a relatively new field within economics, compared to more established areas, such as neoclassical economics or post-Keynesian economic theory.Essentially, behavioural economics stands in opposition to classical economics. This is because behavioural economics, through a combination of both psychology and economics, is based on the assumption that people, when presented with economic decisions, do not always go with the rational option.Behavioural economists would argue that this is because individuals are not completely detached from their emotions when making economic decisions, and as such the heart can overrule the head at times.Classical and neoclassical economic schools of thought, on the other hand, believe that individuals:Are rational economic agents;Who are able to weigh up the benefits and drawbacks of a decision with objectivit y; andAre able to adjust and account for new information when making decisions.Until recently, neoclassical economics has enjoyed a period of almost unrivalled popularity, with many of the schoolâs theories and models taking pride of place among economics students and economists alike.However, with the rise of global events, such as the 2008 financial crisis, that could not be explained by traditional neoclassic economic models, other schools of economic thought are gaining even more traction. Behavioural economics, as a result, is enjoying a period of increased attention, and itâs easy to see why.With a number of Nobel prize-winning economists in the field, along with the fact that behavioural economics helps to better explain why we make the decisions we do, this relatively new, and growing field, will only gain traction.This article outlines some of the key areas of behavioural economics theory, while also highlighting some of the key figures within the field and their respec tive works.Behavioural finance examines trends in the stock markets.

For example, fund managers have a vested interest in understanding how behavioural finance may affect the investment decisions that they make, by helping such managers to understand the unconscious biases that they may hold which influence a decision to buy or sell an investment.Some of the main concepts of behavioural finance are outlined below.Confirmation BiasConfirmation bias is one way through which individuals have a tendency to interpret information in a biased manner. This happens because individuals tend to acknowledge evidence that supports their own interpretations or beliefs while ignoring evidence that may contradict them.Herd InstinctThe idea behind the herd instinct is peopleâs tendency to follow the actions of others without giving much con sideration as to whether they should actually be doing it.Herd instinct can be used to explain changes in the stock market, notoriously bubbles, for example, the dotcom bubble in the 1990s, and large-scale stock sales.Loss AversionLoss aversion is one of the cornerstone concepts of both behavioural finance and behavioural economics more generally. The theory posits that individuals feel the loss of something much more keenly than they feel about the prospect of gaining something. This means that individuals are happier to take a risk to prevent losses.Self-Attribution BiasAlso known as the self-serving bias, this concept has been studied in great detail within psychology. It describes individualsâ tendencies to attribute positive outcomes to their own abilities and knowledge, but to assign negative outcomes with events that were out of their control.Behavioural economics tries to make sense of stock market bubbles and crashes.

Below are just a few of those pioneering economists, although you will come across many more if you end up studying behavioural economics in further detail.Daniel Kahneman and Amos TverskyKahneman and Tversky are, in some circles, considered to be some of the founding figures of the field of behavioural economics.Although Daniel Kahneman has done much to contribute to the field of behavioural economics, oddly enough, he is not actually an economist himself. A psychologist by profession, Kahneman worked with his late friend Tversky on a number of projects, with their collaboration spanning decades.In 2002, Kahneman received the Nobel Prize in economics for his contributions, although Tversky could not be in receipt of the award as well, as the awarding body does not grant posthumous Nobel Prizes.Some of their main contributions to the field of behavioural economics have been concepts such as:Loss aversion (as outlined above); andProspect theory, which in brief, posits that net losses and gains are valued and assessed by individuals differently.Richard ThalerRichard Thaler has certainly received a lot of media attention over the past few years and deservedly so. With a Nobel Prize in Economics under his belt, which was awarded in 2017, the general publicâs interest in behavioural economics has continued grown along with the rise of Thalerâs ideas.Although Thaler has worked with Kahneman and Tversky previously, he is also known for his own achievements. He is perhaps most well-known for theories such as:Bounded rationality;Individualsâ inherent lack of self-control; andNudge theory.Of course, as with any area of economic thought, there are those that support the concepts outlined in behavioural economics, just as there are those that critique the fieldâs ideas.The main detractors of behavioural economics a re economists who believe in the concept of an efficient market, which is understandable, as essentially those that believe in efficient markets believe almost the opposite of what a behavioural economist would when it comes to analysing and predicting consumer behaviour!For instance, Eugene Fama, known as the founder of the theory of market efficiency, is not a fan of behavioural finance. One of his main arguments against behavioural finance is the fact that, while the efficient market hypothesis isnât perfect, itâs better at predicting economic trends and behaviour compared to what behavioural finance or economics is capable of.There are lots of behavioural economics books you can read if you'd like to learn more about this area of economics.
