As such, comparative advantage is an important concept in global trade, and it's the reason many countries concentrate on trying to produce certain goods or services more efficiently than other countries.
In March 2013, the total cost of the Iraq War to date was estimated at $1.7 trillion by the Watson Institute of International Studies at Brown University. Some argue that the total cost of the war to the U.S. economy will range from $3 trillion to $6 trillion, including interest rates, by 2053, as described in the Watson Institute's report.
The costs of the 2003-2010 Iraq War are often contested, as academics and critics have unearthed many hidden costs not represented in official estimates.The most recent major report on these costs come from Brown University in the form of the Costs of War, which totaled just over $1.1 trillion.or example, in a March 16, 2003 Meet the Press interview of Vice President Dick Cheney, held less than a week before the Iraq War began, host Tim Russert reported that every analysis said this war itself would cost about $80 billion, recovery of Baghdad, perhaps of Iraq, about $10 billion per year.
