Gary Becker, widely considered one of the 20th century's most important economists for his work using economics to address social issues, has died at the age of 83. The University of Chicago professor, who won the 1992 Nobel in economics, used what he called "economic analysis" for insight into issues like crime, addiction, family life, and discrimination, Bloomberg reports. In some of his early work, he likened racial or sexual discrimination to a "tax" that hurt biased people as well as those they were discriminating against.
In his Nobel Prize lecture, Becker explained his belief that human behavior is too complicated to be explained by simple self-interest, and that "we'll never have Utopia" because while goods and services may become more abundant, time is still limited to 24 hours a day, Business Insider reports. "He just pushed economics in so many different directions," a professor of economics at the Chicago Booth School of Business tells the Chicago Tribune. "He believed that economics was helpful to understanding and improving people’s lives and that's how he did his research and that's how he taught."
