The Theory of Moral Sentiments by Adam Smith (page 213):
We suffer more, it has already been observed, when we fall from a better to a worse situation, than we ever enjoy when we rise from a worse to a better. Security, therefore, is the first and the principal object of prudence. It is averse to expose our health, our fortune, our rank, or reputation, to any sort of hazard. It is rather cautious than enterprising, and more anxious to preserve the advantages which we already possess, than forward to prompt us to the acquisition of still greater advantages.
Adam Smith’s essay, published in 1759, explains a question that I believe is the basis of behavioral and experimental economics: the question of wealth maximization versus the economics of survival, and their different implications for behavior. Markets cannot be rational if users are not fully rational. When users are forced with the option of wealth or survival, irrational decisions are often made. Would your spending habits change if you were diagnosed with a deadly disease? Would your investment strategy adjust if it were assumed that you would survive forever? Studies have shown that firms (and individuals) that maximize profits are the least likely to be market survivors (3). But what if you do not want to be a survivor, but rather a wealth maximizer? Case-in-point: rational behavior cannot be defined, and your idea of rational may not be the ‘right model’ of rational behavior.
Supporting of the Adam Smith quote above, irrational behavior is most often noted during a downfall. Consider Facebook (FB) who recently surpassed – after one year of trading - their pre-market IPO price. Those who invested in FB made a rational decision: they paid $38 a share. However, as news headlines questioned their rationality (2), many made an irrational decision to sell, buy or hold. Some held even though their ‘rational’ said no because they were anchored to the $38 IPO price; some sold although their ‘rational’ initially believed that the company was worth its selling price today of $45; and some bought although their ‘rational’ initially said the company was a flop. In summary, ‘rational behavior’ is ill defined considering everyone has a different goal and outlook on life. There are many other examples in which people did not act in ways to best suit their needs, but rather got stuck because the numbers did not match (1). For example, consider the recent rise in mutual and index fund investors over the last year due to the surge in US markets; consider the homebuyers prior to the Global Financial Crises who, amongst many other reason, signed considerably generous loans because ‘times were good.’
Irrational behavior is common when it comes to consumer spending as well. Considering I have already wrote a lot more than what is necessary for a discussion board, I will not drift into another subject and turn this into an essay. However, look at the following marketing research recently published by the USF College of Business (4):
1. If there is a situation with a monetary prepayment, consumers will likely spend more. For example, if a person is charged a cover charge to get into a bar, he will spend more money on drinks to make up for the fact that he paid to get into the establishment.
2. If consumers are forced to make a significant effort prior to a purchase decision, they will be apt to, again, spend more money. An example of this would be if a person left his ID card in the car and had to retrieve it to gain entrance into the movies, he would spend more money at the concession stand to compensate for his efforts.
3. If consumers make a considerable time investment to spend, they will be inclined to over-consume and over-indulge. For instance, if a person has to wait in a long drive-thru line at a fast-food restaurant, he will buy more food than he had originally intended to offset the time he invested waiting.
