Perhaps I should reign in the topic and interject with my (semi-) qualified opinions....
If energy prices go up, then everything goes up. Oil is both an input to production and a necessity to transporting those products. Oil costs = inflation. This is why looking at the core CPI is pure bullshit; it doesn't reflect one of the most important factors of inflation (cost-push).
Prices of most things are going up. If one uses inflation (agian, non-core) figures from the CPI-U over teh last three months, our 10-yr yields are around -2.4%. Yields are still negative if you use the PPI for an inflation estimate. Saying that oil price increases are not an issue is absolutely stupid.
If production declines in this circumstance, it means that goods are not being sold, probably because the higher costs have reduced consumer spending. This is absolutly inflationary.
On the other hand (lol) the Fed looks at the core CPI when assessing inflation. the core is steady, so the Fed had ease up of the rate hikes. Personally, I think this is royally stupid, as the inflationary effects of high energy will be seen for an entire inventory cycle. So we will see an even higher discrepancy between yeilds (assuming the current bond trends don't continue) and inflation. Having high negative real rates is not good for investment, especially when so many dollars are held abroad.
As far as economics as a science, I have to agree that the whole subject is as soft as jello. Economics is an exercise in rational thought and debate, not a science (but then why do I have a BS?????). And, though I am against welfare personally from moral and economic standpoints, economics is the study of welfare and resources. It can be argued that by increasing the general standard of living through welfare, it is economically beneficial to all Americans.
On the other hand..........
