Alan Krueger, an economist who advised presidents Bill Clinton and Barack Obama, was found dead on Saturday at his home in Princeton, New Jersey.
He was 58.
Krueger's family said in a statement released by Princeton University, where he taught since 1987, that the cause of death was suicide.
Krueger was the chief economist for the US Department of Labor in 1994 and 1995 under former US President Bill Clinton and was an assistant secretary of the Treasury from 2009 to 2010 and the chair of the White House Council of Economic Advisers from 2011 to 2013 under former US President Barack Obama.
“Alan was someone who was deeper than numbers on a screen and charts on a page,” Obama said in a statement. “He saw economic policy not as a matter of abstract theories, but as a way to make people’s lives better.”
Krueger's latest book, which is scheduled to be released in June, discusses the economics of the music industry, according to The New York Times.
Krueger, Harvard economist Lawrence Katz and economist David Card are known for their research in the early 1990s that found that raising the minimum wage did not, as had been believed, reduce employment rates for low-wage workers - a claim disputed by subsequent studies, including one research projected conducted by economists David Neumark and William Wascher.
Krueger graduated from Cornell in 1983, and earned a doctorate in economics from Harvard in 1987.
He is survived by his wife, Lisa, and two children.
