Irrational Economic Man

One of the basic underpinnings of economic theory is the concept of Rational Economic Man, the idea that we all make economic decisions based on logic and reason. According to this model, when we’re in a grocery store, our thought process goes something like this: “Hmm…butter is $2.39 a pound in this store, but $3.09 a liter in the store across the street…okay, converting to metric, we get…but, wait a second! Unsalted is 30 cents more per pound than salted…okay, assuming I have a heart attack when I’m 60, amortize the cost of my surgery over 50 years of eating salted butter and…yes, I believe salted is economically more sound in the long run…”

Perhaps Rational Economic Woman works this way (the literature is strangely silent on this issue), but we all know from personal experience that Rational Economic Man does not. Confronted with the choice between butter sold by the pound or by the liter, Rational Economic Man will always choose to buy a dozen bags of barbecue potato chips.

Clearly, a new standard in economics is called for. I would suggest, as our model, Irrational Economic Man in recognition of the fact that not all of our decisions are based on rational self-interest. Do you fit the new paradigm?
