Obama won the presidential election in November 2008 and was inaugurated in January 2009.

The winners of Nobel Prizes for medicine, physics, chemistry and literature have been announced in the previous days and the economic prize will be announced next Monday.

The Nobel prizes have been awarded annually since 1901 to those who “conferred the greatest benefit on mankind during the preceding year.”

The prizes are usually announced in October and are handed out on Dec. 10, the death anniversary of Alfred Nobel, a Swedish industrialist and the inventor of dynamite.

Each prize consists of a medal, a personal diploma and a cash award of 10 million Swedish kronor (about 1.4 million U.S. dollars).
