Industrial Production Gain Not As Good As It Looks

Tuesday the Federal Reserve announced that manufacturing output rose 1.1% in July, led by an 9.9% gain in the output of motor vehicles and parts. Over the past year, the output of motor vehicles and parts rose by 32.6%.

But remember, this is an output gain, not a value-added gain. Output measures the number of motor vehicles and parts leaving domestic factories. But it doesn’t take into account any increase in offshoring – that is, use of imported parts.

It turns out that over the past year, imports of motor vehicle “parts, engines, bodies and chassis” rose by 79%. Yowza.

The implication is that there are a lot more imported parts and engines going into ‘American-built ‘ cars and trucks. So value-added in the domestic auto industry – which is what really matters – went up less, maybe a lot less, than 32.6%.
