In this witty and revelatory investigation of the so-called dismal science, University of British Columbia professor Marina Adshade skips the usual widgets and uncovers how the market comes to bear on our most intimate decisions: sex, dating, courtship, love, marriage, even breaking up.

The science of 'sexonomics' is born:

• How much money does an ugly guy need to have to attract as many women via an online dating site as a hot man?
• Is modern marriage just an opportunity to consume more goods and services?
• Does raising the price of beer reduce risky sex?
• Why does a spike in the sale of sex toys predict an upcoming recession, while an increase in the number of breast lifts indicates a perkier economy is on the way?
• Which comes first: a prosperous nation or a promiscuous one?

Once you read Dirty Money, you'll never look at your money - or your relationships - the same way again
