Experts at the Organization for Economic Cooperation and Development say growth is slowing for major economies around the world.
An OECD report Monday analyzes data gathered in October that is intended to give a look at future economic growth.
The OECD says Brazil, Russia, India, China, Europe, and the United States all will expand more slowly over the next six months.
Later this week in the United States, officials at the Federal Reserve will review the state of the world's largest economy and set interest rates. New information also is expected from the government about inflation and factory production.
