Nobel Prices for Literature

According to its official website, the Royal Swedish Academy of Sciences "administers a researcher exchange with academies in other countries and publishes six scientific journals. Every year the Academy awards the Nobel Prizes in Physics and Chemistry, the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel, the Crafoord Prize and a number of other large prizes".
Each September the Academy's Economics Prize Committee, which consists of five elected members, "sends invitations to thousands of scientists, members of academies and university professors in numerous countries, asking them to nominate candidates for the Prize in Economics for the coming year. Members of the Academy and former laureates are also authorised to nominate candidates." All proposals and their supporting evidence must be received before February 1. The proposals are reviewed by the Prize Committee and specially appointed experts. Before the end of September, the committee chooses potential laureates.
If there is a tie, the chairman of the committee casts the deciding vote. Next, the potential laureates must be approved by the Royal Swedish Academy of Sciences. Members of the Ninth Class (the social sciences division) of the Academy vote in mid-October to determine the next laureate or laureates of the Prize in Economics. As with the Nobel Prizes, no more than three people can share the prize for a given year; they must still be living at the time of the Prize announcement in October; and information about Prize nominations cannot be publicly disclosed for 50 years.
With the Nobel Laureates in Physics, Chemistry, Physiology or Medicine, and Literature, each Laureate in Economics receives a diploma, gold medal, and monetary grant award document from the King of Sweden at the annual Nobel Prize Award Ceremony in Stockholm, on December 10—the anniversary of Nobel's death.
On October 15, 2007 the Royal Swedish Academy of Sciences, the Bank of Sweden, and the Nobel Foundation announced the Academy's award of the Prize in Economic Sciences to three Americans, Leonid Hurwicz, Eric Maskin, and Roger Myerson, "for having laid the foundations of mechanism design theory.
