141: Unraveling the Mysteries of Behavioral Economics in Richard H. Thaler's 'Misbehaving'

Resúmenes de lectura rápida

How does Thaler define 'misbehaving' within the context of economics, and what are some examples he uses to illustrate this concept?

Richard Thaler, one of the pioneers of behavioral economics, uses the term "misbehaving" to describe actions or decisions that deviate from traditional economic models and rational choice theory. In the context of economics, "misbehaving" refers to the ways in which actual human behavior often violates the principles of classical economic theory, which assumes that all individuals are rational and consistently aim to maximize their utility.
Thaler argues that humans are predictably irrational in many ways, influenced by biases and heuristics that lead to decisions that are not always perfectly aligned with their best interests or economic predictions. "Misbehaving" in this sense is not so much about misbehavior in a moral or ethical context, but rather about illustrating the quirks and idiosyncrasies of human behavior that cause deviations from expected economic models.
In his book "Misbehaving: The Making of Behavioral Economics," Thaler provides numerous examples of such behavior:
1. **Loss Aversion**: People tend to prefer avoiding losses over acquiring equivalent gains. For instance, losing $100 feels more painful than the pleasure derived from gaining $100. This asymmetry can lead to decisions that seemingly contradict economic rationality, such as holding onto losing stocks to avoid realizing a loss.
2. **Endowment Effect**: Individuals ascribe more value to things merely because they own them. Thaler demonstrated this with experiments involving coffee mugs and chocolate bars, where participants valued these items more highly once their ownership of the items was established, compared to how they valued them before taking ownership.
3. **Mental Accounting**: People often segregate money into different accounts based on subjective criteria, which can lead to irrational spending behaviors. For example, someone might treat a $1000 tax refund differently from a $1000 paycheck or a $1000 lottery win, even though all three sum up to the same amount of money in economic terms.
4. **Planner-Doer Model**: Thaler explores the conflict between a person's long-term plans and short-term actions. People might plan to save for retirement or stick to a diet, but often give in to the temptation to spend money or eat unhealthily in the short term.
5. **Social Preferences**: People care about fairness and cooperation. Thaler notes that people are willing to sacrifice their own gains to punish someone who is behaving unfairly, a behavior that classical economics would consider irrational as it does not maximize individual utility.
Through such examples, Thaler illustrates how traditional economic models, predicated on rational actors making decisions purely to maximize utility, often fail to predict actual human behavior. His work in documenting these deviations has been instrumental in developing the field of behavioral economics, which seeks to provide more accurate models by incorporating psychological insights into economic theory.
What role do social norms play in shaping economic decision-making, according to "Misbehaving"?

In Richard H. Thaler’s book "Misbehaving," social norms are highlighted as a significant influence on economic decision-making, diverging from the traditional economic theory that assumes individuals always make rational choices to maximize their utility. Thaler, a pioneer in the field of behavioral economics, argues that people are deeply influenced by social norms, which are the usual, culturally expected behaviors in a society.
Social norms can affect economic decisions in a variety of ways:
1. **Fairness**: Thaler discusses how notions of fairness, which are guided by social norms, can influence pricing strategies, wage setting, and market transactions. For instance, during times of high demand or scarcity (like during a natural disaster), sellers who raise prices excessively may be viewed as violating fairness norms, leading to consumer backlash despite the potential for higher profits.
2. **Reciprocity**: Economic transactions are not always carried out with immediacy and strict adherence to the profit maximization principle. Instead, decisions can be based on reciprocal relations. If a business treats its customers or employees well, these groups are more likely to remain loyal, reciprocating the goodwill, even if it's not the economically "rational" choice in a narrow sense.
3. **Conformity**: Individual economic behaviors are also influenced by observing and conforming to the actions and preferences of others. For example, if people see others investing in a certain stock or buying a particular product, they might be inclined to do the same, regardless of the intrinsic value or utility derived from that decision.
By incorporating these factors into the analysis of economic behaviors, Thaler suggests that models predicting human behavior can be made more accurate and reflective of real-world scenarios, where social expectations and norms significantly shape decision-making processes. This perspective helps in understanding why people often make choices that seem to defy traditional economic rationality.
What is the endowment effect, and how does this phenomenon challenge classical economic theories? How does Thaler use it to support his arguments in "Misbehaving"?

The endowment effect is a psychological phenomenon where people assign a higher value to objects they own compared to objects they do not own. This effect suggests that once possession is established, people are likely to demand much more to give up an object than they were willing to pay to acquire it. Essentially, ownership increases the item's perceived value.
The endowment effect challenges classical economic theories, particularly those relating to rational choice and market behavior, which assume that economic agents behave in a manner that maximizes their utility based on stable preferences. According to these classical theories, the value of an item should be consistent regardless of ownership. However, the endowment effect demonstrates that people's preferences can be inconsistent and influenced by factors unrelated to the intrinsic value of the goods, such as their sense of ownership.
Richard Thaler, a leading behavioral economist, uses the concept of the endowment effect extensively in his book "Misbehaving" to illustrate how real human behavior often deviates from theoretical predictions made by classical economics. Thaler argues that these deviations are not anomalies but rather systematic and predictable patterns that need to be understood and incorporated into economic theory.
In "Misbehaving," Thaler uses the endowment effect among other behavioral concepts to argue for a more realistic and accurate representation of economic behaviors in economic models, which he terms "behavioral economics." He posits that traditional models fail to account for how real people actually think and make decisions. Thaler's work, including his discussion of the endowment effect, has been instrumental in questioning and expanding the boundaries of economic theories to include psychological insights and more complex, nuanced understandings of human behavior in economic contexts.
