Mr friend Dr. S. (B.A., Princeton; M.S., MIT; M.D., Yale) shared with me a long time ago a stunningly innovative solution to a difficult group-living problem. I will now share that solution with you, my highly esteemed blog co-participants.
The group-living problem: No one does the dishes. They pile up, festering in the sink. The longer the dishes stay in the sink, the less anyone wants to wash one and use it. The equilibrium is all the dishes piled in the sink and culturing new weapons for germ warfare, and the housemates using papers plates and plastic utensils.
Can economics offer economic man a better life? Indeed it can.
The solution is refrigeration. Actually, freezing. In group living situations, no one goes shopping, either. Thus the freezer is empty. So you just put the dirty dishes in the freezer. Then when someone wants to use a dish, he simply takes it out of the freezer and gives it a quick rinse. This is incentive-compatible, just-in-time dishwashing.
I realize that the parameters might be different for women. I myself have always believed that “economic man” is a ridiculously narrow, unrealistic model of humanity.
