This three-picture sequence shows images over the years from the New York Stock Exchange (NYSE) in New Tork City. At left traders work the floor of the NYSE in an undated photo; traders on October 19, 1987 (CENTER) when the Dow Jones dropped over 500 points, then the largest decline in modern time; and on October, 6, 2008 (RIGHT) as Wall Street tumbled following the opening bell in the fallout from the credit crisis, triggering concerns about the economy, and the Dow falling below 10,000 for the first time in four years. Economists interviewed by AFP about the reforms likely to result from the current crisis spoke in the broad context of some of the great economic events in the 80 years since the crash of 1929.
