The economics of love, marriage and dirty dishes

Economics is about choice – and choices occur in all parts of our lives. One area is personal relationships. Are we making the best of our relationships with family, friends and sexual partners? Increasingly economists are examining human behaviour in such contexts and asking what factors determine our decisions and whether such decisions are rational.

A recent book looks at the economics of marriage and goes under the title of ‘Spousonomics‘. Its authors, Paula Szuchman and Jenny Anderson, use economics “to master love, marriage and dirty dishes”. As they say:

Every marriage is its own little economy, a business of two with a finite number of resources that need to be allocated efficiently.

They look at ways in which such resources can be allocated efficiently. They also look at apparently irrational behaviour and seek to explain it in terms of various ‘failures’ (akin to market failures). They also examine how these failures can be rectified to improve relationships.

So is this economics stepping on the toes of relationship counsellors and psychologists? Or is this the legitimate domain of economists seeking to understand how to optimise in the context of scarce resources – including time and patience?
