These are questions that might help us getting a better understanding of what went wrong in the first place and, perhaps, how we can avoid or mitigate the next worldwide economic collapse.
Wikipedia defines rationality as follows:
Individuals or organizations are often called rational if they tend to act somehow optimally in pursuit of their goals.In economics, "goal" is usually translated into optimizing one's expected payoff according to a utility scale, or in a simpler sense, into maximizing one's expected profit. Therefore, loosely speaking, people are economically rational if they try to maximize their expected profit.
There are, however, many ways in which we can see people behave systematically against their own goal. In an earlier post, we talked about wishful-betting and wishful-thinking, which could be considered as examples of how people behave irrationally in a systematic way.
Peter Ubel in his book "Free Market Madness: Why Human Nature is at Odds with Economics" argues that a completely free-market, which is a concept based on rational behavior, is dysfunctional. That is, people's potential to behave irrationally always necessitates a level of market regulation. These regulations should prevent people from making irrational decisions on a large scale.
The author believes that the roots of the current economic disaster can be found in the irrational behavior of individuals.
Ubel, too, believes in wishful-thinking as a source of irrational behavior. However, he gives it a new name: unrealistic optimism.
As an example, unrealistic optimism in believing that the housing prices always go up, was one of the reasons that we fell into this economic downturn in the first place.
I received these feedbacks through my communication with my valued friend Amir Kermani (his points but in my words).
- Wishful thinking might lead to wrong expectations. We should keep in mind that this is only one of the sources that might lead to irrational behavior.
- Before the government can prevent any wrong expectations, it should have the ability to obtain more accurate ones itself. There is no gaurantee that the government can set its expectations more accurately than the firms or individuals. Therefore, government regulations cannot be the ultimate solution for this probem.
- We should also look for the sources of wrong expectations. That is, why and how people fall into this trap in the first place. We should look for the root causes not just the symptoms.
Ubel talks about his book in an interview with Harvard Business Online. You can listen to this interview by clicking here.
