Lars P. Hansen is a professor at the University of Chicago. He says Monday morning's phone call from Sweden came when he was on his way to the gym. He calls the win a surprise.
Hansen won along with Eugene Fama, who teaches at the University of Chicago's Booth School of Business. A Yale professor also won.
Hansen has taught at the Hyde Park school since the early 1980s. He considers himself an "econometrician." His work studies the intersection of economics and statistics.
The 60-year-old is still actively performing research and hopes the prize will help promote "good research" in his field.
