Daniel Kahneman, who never took an economics course but who pioneered a psychologically based branch of that field that led to a Nobel in economic science in 2002, died on Wednesday.
His death was confirmed by his partner, Barbara Tversky.
Professor Kahneman, who was long associated with Princeton University and lived in Manhattan, employed his training as a psychologist to advance what came to be called behavioral economics.
(Ms. Tversky had been married to Professor Tversky, who died in 1996.
She and Professor Kahneman became partners several years ago.)
