Even the big boys make mistakes: Economist err compiling "Doing Business Index"

From today's WSJ:



The World Bank repeatedly changed the methodology of one of its flagship economic reports over several years in ways it now says were unfair and misleading.



The World Bank’s chief economist, Paul Romer, told The Wall Street Journal on Friday he would correct and recalculate national rankings of business competitiveness in the report called “Doing Business” going back at least four years.



The revisions could be particularly relevant to Chile, whose standings in the rankings have been especially volatile in recent years and potentially tainted by the political motivations of World Bank staff, Mr. Romer said.
