John Pierce: Who have you come across who are the most, I suppose important or insightful economists, and what sort of questions were
they trying to answer?
Ross Gittins: Well, lots of people I guess, but one guy who had a big influence on me is Robert Frank from Cornell. He's the man who first
introduced me to behavioural economics, which is the kind of, which is a combination of economics and psychology. It's saying,
what can the psychologists tell us about the way people behave and the way they make decisions. That's a cutting edge of economics
and I'm very interested in that. It's really, behavioural economics is very useful if you're trying to figure out why politicians
do the things they do, for example. But, so he introduced me to behavioural economics. He's interested in a lot of other subjects
on the edge of economics, such as why, for example, why do people give tips in restaurants that they're not going to visit
again, they know they're not going to come back to because they're just passing through town or whatever. Why do people do
that? Well, you can think of reasons why it makes sense for people to do it. Partly people do it because they're trying to
say something about themselves: 'I'm a decent person. If you give me good service I'll reward it. I won't do this on the cheap.'
They're partly saying something about themselves. But they're also saying, sending a message, and this is the thing that Frank
was on about, they're sending a message that says: 'I'm the kind of person you can trust. I'm a person you can rely on.' That's
an important message and it's actually an economic message if you look at economics more broadly than just the very narrowest
interpretation of the model.
