BANGALORE, India \ufffd The exodus of Indian engineers mostly to the United States costs India $2 billion annually, according to a recent U.N. study.

While the United Nations Human Development Report 2001 stresses that "technology itself has become a source of economic growth" for countries like India, many of the benefits are being outweighed by the brain drain of engineering talent.

"Rich nations have been opening their doors to developing-country professionals at a high cost to the home countries," the U.N. study warned. Based on the $15,000 to $20,000 average total cost of providing a university education in India, the country losses as much as $2 billion a year in technical investment.
