Fighting against statism in Washington is a lot like trying to swim upstream. It seems that everything (how to measure spending cuts, how to estimate tax revenue, etc) is rigged to make your job harder.
A timely example is the way the way government puts together data on economic output and the way the media reports these numbers.
Just yesterday, for instance, the government released preliminary numbers for 4th quarter gross domestic product (GDP). The numbers were rather dismal, but that’s not the point.
I’m more concerned with the supposed reason why the numbers were bad. According to Politico, “the fall was largely due to a drop in government spending.” Bloomberg specifically cited a “plunge in defense spending” and the Associated Press warned that “sharp government spending cuts” are the economy’s biggest threat in 2013.
To the uninitiated, I imagine that they read these articles and decide that Paul Krugman is right and that we should have more government spending to boost the economy.
But here’s the problem. GDP numbers only measure how we spend or allocate our national income. It’s a very convoluted way of measuring economic health. Sort of like assessing the status of your household finances by adding together how much you spend on everything from mortgage and groceries to your cable bill and your tab at the local pub.
The same principle is true – or should be true – for a country.
That’s why the better variable is gross domestic income (GDI). It measures things such as employee compensation, corporate profits, and small business income.
