Iraq war hits U.S. economy: Nobel winner

By Daniel Trotta

NEW YORK (Reuters) - The Iraq war has contributed to the U.S. economic slowdown and is impeding an economic recovery, Nobel-winning economist Joseph Stiglitz says.

Meanwhile, the U.S. government is severely underestimating the cost of the war, Stiglitz and co-author Linda Bilmes write in their book, "The Three Trillion Dollar War" (W.W. Norton), due to be published on Monday.

The nearly 5-year-old war, once billed as virtually paying for itself through increased Iraqi oil exports, has cost the U.S. Treasury $845 billion directly.

"It used to be thought that wars are good for the economy. No economist really believes that anymore," Stiglitz said in an interview.

Stiglitz and Bilmes argue the true costs are at least $3 trillion under what they call an ultraconservative estimate, and could surpass the cost of World War Two, which they put at $5 trillion after adjusting for inflation.

The direct costs exclude interest on the debt raised to fund the war, health care costs for veterans coming home, and replacing the destroyed hardware and degraded operational capacity caused by the war.

In addition, there are costs not accounted for in the budget such as rising oil prices and social and macroeconomic costs, which the book details.

To illustrate how the money could be spent elsewhere, Bilmes cited the annual U.S. budget for autism research -- $108 million -- which is spent every four hours in Iraq. A trillion dollars could have hired 15 million additional public school teachers for a year or provided 43 million students with four-year scholarships to public universities, the book says.
