Who has a deeper sense of fairness, a mortgage banker or a chimpanzee?

In effect, both chimpanzees and bankers have been made to take to a test called the “Ultimatum Game.” Commonly conducted in behavioral economics research, the procedure involves giving the first of two players a certain sum of money to divide.

This person can keep as much of it as he wants and pass the rest along to the second player. The second player can either accept what the first player offers or cancel the whole deal, in which case neither player gets anything.

...

Not that well. According to short-sale broker Jeremy Brandt, bankers holding the first mortgage are typically offering the second mortgage holders only a pittance— about 10 percent of the value of their loans. In the case outlined above, that means they get $6,000 to go along with a deal that will save the first lien holder $40,000. In ultimatum-game terms, that’s an 85/15 split—a deal that would appeal to a chimpanzee but not most normal humans. In conclusion, you could say that bankers behave in a more economically rational manner than either human or chimpanzee test subjects in a lab. Or, alternatively, you could say that bankers are greedier than jungle animals.

The test subjects are poorly chosen. It should be redesigned to work with sharks for an accurate comparison.
