Today in the U.S., couples have a 1 in 3 chance of their marriage ending in divorce. Common stressors include money, parenting techniques, allocation of housework and (of course) the amount of sex. But did you know that such marital problems can be fixed simply by applying a few principles of economics?

Meet Paula Szuchman and Jenny Anderson. Their book, Spousonomics: Using Economics to Master Love, Marriage and Dirty Dishes, uses basic economic tools such as supply & demand, division of labor and allocation of resources to build a roadmap to marital bliss. For example, in any relationship, the resources of time, energy, love and libido are always in short supply. Spousonomics challenges couples to determine what is most important at any one time and then teaches them how best to allocate these limited resources.

Szuchman and Anderson interviewed over 200 couples to formulate their theories and teachings. Now, My Generation is cashing in on their wealth of nuptial knowledge.
