I’ve finally finished Tim Harford’s book “The Undercover Economist”. I highly recommend it to anyone who wants to gain some insight into the economic questions that really effect us.

Forget about the behaviour of small firms or the slope of the IS/LM curve. Think about why people get out of bed in the morning, pay silly prices for a cup of coffee and can’t build a business on Cameroon. Think about how China has grown so fast. How did it happen? Why?

I was lucky enough to attend a lunch last Friday in Wellington (thanks Jim for the head’s up) and hear Tim talk about his new book “The Logic of Life”. I’m looking forward to reading it. It crosses back and forth across the social science spectrum which i believe is incredibly important for an economist to do.

It’s not just about numbers and graphs. As Tim says, it’s about people and the things they do, resources they use and how and why they do it. When I studied economics (University of Manchester 1987!) we lived in a faculty of social science with the option to major in one of 11 different topics as diverse as social anthropology to accounting and finance. These days you’re likely to find economics buried in the commerce faculty.

This approach has failed the student as it presents economics as being about business and numbers. It isn’t at all. Those are merely outcomes and outputs. How people allocate scare resources is a combination of anthropology, psychology, politics, finance, geography , history and so on.

The silo approach that many universities have taken goes counter to the understanding we have developed of systems and the extra efficiencies that coherence or consilience brings.

Economists like Tim Harford will bring new interest to this critical subject and hopefully widen the lens that it is viewed through. After all any economist who can discuss the market for blow jobs with a straight face has to be on to something
