Lecturer Paul Hansen lives halfway between the beach and the University - perfect for a guy whose love of surfing is rivalled only by his passion for Economics.
"It's a fascinating subject," says Hansen. "It's not just about money and business but about interactions between people. You can use the principles of supply and demand, cooperation and competition to try to explain the society we live in - even things like love and marriage and criminal behaviour."
Hansen caught the surfing bug as a teenager in Dunedin. He turned on to Economics a year later, inspired by a great teacher at school.
Hansen did a BCom and a Postgraduate Diploma in Economics at Otago, followed by a Master's in Australia and a PhD back at Otago.
After 22 years studying Economics, he feels he's just explored the tip of the iceberg. "I still haven't figured it all out. I'm still a long way off."
But he's still fascinated - even when the surf's up. "I find myself sitting on my surfboard thinking about work, just because I enjoy it so much."
And although he's lived in Stockholm, Canberra, and Wellington, he still loves Dunedin, where "you can live like a student if you want to. It's cheap and interesting - and the surf's good."
