In the last decade, new federal regulations have forced academics who receive money from drug companies to disclose those ties when writing and speaking about their products. An article in The New York Times  suggests that such conflicts of interest may have been going on for some time -- undisclosed -- involving academics who defend controversial Wall Street trading practices. A number of such academics do work for parts of Wall Street, or their academic programs receive gifts from businesses that benefit from the research. In many cases, the Times said, these ties have not been reported. Professors told the newspaper that their views were not influenced by the ties to the finance industry.
