The Economics of Men Behaving Badly

From Economix:

One controversial study by Christin L. Munsch, a doctoral candidate in sociology at Cornell, found that men who are more financially dependent on their wives are more likely to cheat. Again, this goes against what economics would predict, but seems to indicate that a lower level of power and threatened masculinity may also tempt men to transgress.

When it comes to the economic point of view in this debate, I do think that institutional economics, behavioral economics, and even some evolutionary approach to economics have more to say than a neoclassical microeconomic approach (costs and benefits, maximizing utility, etc.).
