A British-born Jewish American professor has been awarded the Nobel Prize in economics, winning half of the $924,000 prize money.
Oliver Hart received the honour alongside Bengt Holmstrom, a professor of economics and management at the Massachusetts Institute of Technology.
Mr Hart, who is a professor of economics at Harvard University, was awarded for his work on contract theory, which studies how contracts allow people to deal with conflicting interests, on Monday.
According to information provided by the academy, the 68-year-old carried out his Nobel-winning work in the 1980s.
