What roles do the World Bank and the IMF play in global finance?

"The International Monetary Fund (IMF) was founded in 1945, one year after the creation of the World Bank, to promote trade through financial cooperation and eliminate trade barriers in the process. The IMF makes short-term loans to member nations that are unable to meet their budgetary expenses. It operates as a lender of last resort for troubled nations. In exchange for these emergency loans, IMF lenders frequently extract significant commitments from the borrowing nations to address the problems that led to the crises. These steps may include curtailing imports or even devaluing the currency. Some global financial problems do not have a simple solution. One option would be to pump a lot more funds into the IMF, giving it enough resources to bail out troubled countries and put them back on their feet. In effect, the IMF would be turned into a real lender of last resort for the world economy. The danger of counting on the IMF, though, is the “moral hazard” problem. Investors would assume that the IMF would bail them out and would therefore be encouraged to take bigger and bigger risks in emerging markets, leading to the possibility of even deeper financial crises in the future."
