This is a perfect Valentine’s Economics read which is brilliantly funny and applies the concepts learnt in Economics to the real world of love and dating. It is a semi-autobiographical account of William who is an economist. This means he is good at reducing an infinitely complex world into a set of clear, rational principles about the way people and markets behave. He sets out to apply the rules of economics to save his floundering love life. For a time, everything seems to be clearer. Want to play hard to get? Reduce your supply. Want a girlfriend? Find an undervalued asset. Why are all the good ones taken? That will be the Efficient Market Hypothesis.
