Excerpt:
Economist Shoshana Grossbard admits she was naive when she did her doctoral thesis on polygamy more than 30 years ago at the University of Chicago.
Then, she believed that a simple supply-and-demand analysis would explain the economics of polygamous societies.
Besides, she says, "I thought it was cool to say that polygamy might be advantageous to women and repeat what Gary Becker (her thesis adviser and Nobel laureate) has said."
Now, having written several books on the economics of marriage, Grossbard says, "I know better."
