Question

Consider the following story taken from the New York Times on housing prices: “From 1989 to 1992, prices in Boston fell sharply, with condominium prices dropping as much as 40 percent. For a great many of those who bought condominiums during that period, selling could be done only at a significant loss. And, basically, many people refused to sell....For essentially identical condominiums, people who had bought at the peak and were facing a loss generally listed their properties for significantly more than those who had bought at a time when prices were lower....Properties listed above the market price just sat there.” What behavioral biad can explain why more people did not sell their home during this time?

Status quo bias.

The mechanics of the reflective system.

The decoy effect.

Loss aversion.

Explanation / Answer

the decoy effect (or asymmetric dominance effect) is the phenomenon whereby consumers will tend to have a specific change in preference between two options when also presented with a third option that is asymmetrically dominated. An option is asymmetrically dominated when it is inferior in all respects to one option; but, in comparison to the other option, it is inferior in some respects and superior in others. In other words, in terms of specific attributes determining preferability, it is completely dominated by (i.e., inferior to) one option and only partially dominated by the other. When the asymmetrically dominated option is present, a higher percentage of consumers will prefer the dominating option than when the asymmetrically dominated option is absent. The asymmetrically dominated option is therefore a decoy serving to increase preference for the dominating option. The decoy effect is also an example of the violation of the independence of irrelevant alternatives axiom of decision theory.
