I don't know about you but I am having fun with this discussion.
I agree Buffet as a stock picker is smarter than any and all economists ever put on this earth. I won't argue that.
But he is an analyst of businesses and the general business environment and the econspeak "stagflation" is not really in his area. I don't ask the most brilliant native german speaker to define and characterize words in english and I don't ask the greatest stock picker of all time to characterize a term specific to a rare macroeconomic condition. Is he capable of a good opinion, yes. Should we take it into consideration, yes. But the term came out during a period of double-digit inflation and low growth. We are so spoiled by stable prices (thanks to economists like Volcker and Greenspan) that we forget what real stagflation is. That is my only point.
I am very glad you ask why food and energy don't matter. First, they do matter very much to consumers. Which is to say, all of us.
However, as a class of goods, food and energy represent highly inelastic necessities that consumers have an extremely difficult time substituting. Because of this, policymakers can do little to control for these prices in the short run.
one other reason for separating food and energy prices out from core inflation is that energy and food prices are subject to wider variation and can distort the overall underlying trend. Factors such as OPEC and weather lead to wild swings in these factors. Again, monetary policy can do nothing about the weather or the supply of oil. So factoring out food and energy gives a clearer picture of the underlying price pressures.
The problem of inflation is a big problem. It is a disease on the face of an economy. It represents a tax on Consumers but unlike an income tax nothing is flowing to the government and Nobody Is Gaining Any Benefit from the tax. even worse, inflation alters the behavior of consumers in a way that causes more inflation. Individuals, acting in their own self interest, actually make this situation worse by spending more rapidly and feeding inflation. When inflationary expectations became embedded in psychology of the American consumer, producers became more able to pass on higher import costs from factors such as energy back on to consumers. And consumers again continue to spend as fast as possible factor than prices can rise. The cycle just feeds off of itself.
Now here's the catch. In the short-run the amount of dollars able to be spent is fixed. If food energy prices are rising, that represents a cost to consumers that causes them to spend less on other goods. This is the case now and it is not an environment where producers can't raise prices on consumers very easily. What we see is that the economy will actually contract, and for the most part we are seeing that right now.
Whenever an economy is in recession it is extremely difficult for prices to rise. Demand shifts to the left, businesses layoff, and eventually inventories pile up and need to be sold off at lower prices.
During the 1970s we were able to see a period of high inflation and low growth. This was a special situation and there were some very important factors that were largely responsible. The first that was loose monetary policy when we needed to be tight. Most people blame political reasons on this and if you look into history books you'll find that President Nixon put a Fed chairman in and that would do exactly what he wanted to do -- speed up the economy and get him reelected. Secondly, we went off the gold standard which was a major realignment in our monetary system that allowed for prices to rise. Next, the baby boomers all came of age at about the same time and started buying things like houses and furniture, etc.. That is to say aggregate demand became more inelastic. Now throw an oil embargo and the Nixon administration's attempt at price controls. The 1970s were a true stagflation because the economic environment was a perfect storm for price is to start rising rapidly and for people to adjust the way they behave.
The economic environment right now is extremely challenging but it is eons away from being consistent with a stagflation environment. first of all, we are in a credit crunch. Businesses might want to raise capital right now and take their positive net present value projects to increase the value of their companies but they cannot because they cannot get funding.
Businesses are not expanding they are contracting. The labor market is not expanding it is contracting. And most importantly, incomes are not rising (you can ignore today's personal income and spending report as it is only indicative of economic stimulus checks and will not represent more than a blip on the radar screen). In real terms incomes are falling rapidly because of the energy inflation.
So in a nutshell this environment is not consistent with noncore inflation spilling over into core inflation and giving us a real stagflation.
I put together an econometric model with a student of mine last week based on fundamental factors. We cannot force-feed numbers into it that bring fair value of oil a barrel above $100. This situation cannot persist. Of course as Keynes said, "the market can stay irrational longer than you can stay solvent."
Gas belongs at about $2.50 right now and the idea of $7.00 gas is fantasy. We will have massive global instibility of epic proportion if this happens. I believe markets will at some point self resolve.
Finally, I appreciate your comments about houses being left out of the consumer price index but my guess is that it is because we don't consume houses. They represent an investment more than a consumer good.
Thanks for your stimulating comments. This is a great website!!
