Stiglitz on McCain: If He Doesn't Understand the Economy, He Doesn't Understand Security | Posted March 4, 2008

Stiglitz was awarded the Nobel Prize for Economics in 2001. He is the author, with Linda Bilmes, of The Three Trillion Dollar War: The True Cost of The Iraq Conflict, just published in the U.S. Stiglitz spoke with me for my Global Viewpoint on Monday.

Joseph Stiglitz: The war has led directly to the U.S. economic slowdown. First, before the U.S. went to war with Iraq, the price of oil was $25 a barrel. It's now $100 a barrel.
While there are other factors involved in this price rise, the Iraq war is clearly a major factor. Already factoring in growing demand for energy from India and China, the futures markets projected before the war that oil would remain around $23 a barrel for at least a decade. It is the war and volatility it has caused, along with the falling dollar due to low interest rates and the huge trade deficit, that accounts for much of the difference.

That higher price means that the billions that would have been in the pockets of Americans to spend at home have been flowing out to Saudi Arabia and other oil exporters.

Second, money spent on Iraq doesn't stimulate the economy at home. If you hire a Filipino contractor to work in Iraq, you don't get the multiplier effect of someone building a road or a bridge in Missouri.

Third, this war, unlike any other war in American history, has been entirely financed by deficits. Deficits are a worry because, in the end, they crowd out investment and pile up debt that has to be paid in the future. That hurts productivity because little is left over either for public-sector investment in research, education and infrastructure or private-sector investment in machines and factories.

Until very recently, we haven't sharply felt these three factors depressing the economy because the Federal Reserve Bank responded with the attitude that they must keep the economy going no matter how much President Bush spends on the Iraq war. Seeing a weak economy, they kept interest rates low, flooded the economy with liquidity and looked the other way when bad home-lending practices were shoveling money out the door. Regulation was lax. The spigot was wide open. More than $1.5 trillion was taken out of houses in mortgage equity withdrawals alone over the past five years! That is a huge amount of money to be spent. ...

Gardels: The economic costs have now come back to undermine the whole post-9/11 security effort. When John McCain says he's not interested in and doesn't understand the economic aspect of things, and only knows about how to keep America safe, what does that say about his leadership capability?

Stiglitz: If he doesn't understand the economy, he doesn't understand security. If we had infinite resources, we might be able to have perfect security. But America, like every other country, has resource constraints. That means you need to be smart -- that is, economic -- about the money we spend. If you weaken the American economy, you won't be able to find the resources you need for security. The two cannot be separated.
