News of the Obvious: Warfare Economics Edition

The Reformed Broker highlights an economic study:

The Institute for Economics and Peace is out with a monumental piece of research on how wars affect the US economy...
The bottom line in their findings is that:

• Public debt and levels of taxation increased during most conflicts;
• Consumption as a percent of GDP decreased during most conflicts;
• Investment as a percent of GDP decreased during most conflicts;
• Inflation increased during or as a direct consequence of these conflicts.

Sure, the Institute for Economics and Peace may be biased about the costs of war, but I think these observations are pretty obvious.  I think I probably could have guessed each of those answers without thinking too hard.
