Chicago -Gary Becker, whose work applying the principles of economics to a wide range of human behavior won the Nobel Prize in 1992, has died at age 83, the University of Chicago said on Sunday.

Becker, a student of free-market economist Milton Friedman, died on Saturday after a long illness, the university said on its website. It gave no more details.

Becker used economic analysis to study such subjects as crime, discrimination, addiction, population and the family, the university said.

“Gary was a transformational thinker of truly remarkable impact on the world and an extraordinary individual,” University of Chicago President Robert Zimmer said in a statement.
