I really don't understand what the intellectual foundation is of your argument. No where have I ever seen a theory put forward that posits that the size of fluctuations in headline inflation has any macro-economic predictive power beyond the limit extent to which it serves as a negative shock. The Keynesian argument is straightforward, inflation is linked to aggregate supply and demand and the imbalance in those we are seeing is putting a drag on investment and consumption.
Furthermore I would say that we are clearly in a depression, albeit a relatively mild one. Interest rates have been at next to zero for more then three years. We are still experiencing sustained elevated unemployment. That is a very workable definition of a depression.
If you want to play the Hayek card then you are really changing the rules quite extensively. For one thing, you are positing that any government spending will crowd out public spending. I would very much like to know through what channel that is supposed to happen. Additionally you need to explain why we aren't experiencing hyperinflation, as Hayek says we should have been doing since 2008.
And the 70s comparison is case in point of what I'm saying. In the 70s, you say huge inflation driven by a feedback cycle of prices and wages. We are clearly not seeing that today:

http://research.stlouisfed.org/fred2/graph/?g=19S
As long as wages and interest rates remain depressed, we are not in an inflationary environment.
All of this really shouldn't be the debate though. Inflation is negatively correlated to unemployment. Have you seen those unemployment numbers lately?
I think I said that inflation or CPI-U are all phenomena observed, and thus are indicators very clearly. First of all, economics is not pure mathematical analysis like other science, its always based on observations. Second, economy is not a machine that push as they want and it do as they said, it's more complex as if organic. Hence if you see there is a phenomena like inflation rate, unemployment rate, GDP change rate, import/export change rate, then you know there are causes behind it.
Something very clear that we are observing a recession (I don't believe that it's going down into depression yet, but will gradually sink into it). By observing there are businesses going out or downsize at large scales, there are mass lay off because of that, and wages are cut because of that. Even the ones are hired back will force to accept lower wages. And the production decreased accordingly (you can see that from PPP, it's easy to understand, no workers no products). They are all direct result of the businesses problems, but it's also an observed phenomena, so what's causing business to loose faith? Then that's a big question. I don't think it can be explained easily but over-all it's coming down to the over-confidence in financial market. People chasing the money gain with way too much risks, and many business credits are busted because of it.
Set that aside, let's see what's causing inflation/deflation. And it's a good question too, and what's the root of depression of credibility translate into
the change rate of currency/commodity ratio on the open market (namely the price). First, about hyperinflation, its the most easy cause and effect from lose of faith into price. Since there are 3 factors in price -
currency,
commodity, and
open market. Hence first thing about hyperinflation is that it always comes with the underground black market. People's lives goes on, they need to eat, but if you loose faith either with the currency itself or the government supervising the open market, people have to buy goods somewhere. With that more and more commodities driven into black market, price rise up even higher in open market, the negative feedback loop is born. It's straight and simple. And not happening in a country like US with very strong governments and large market infrastructures. Also most modern technologies (electronic transaction, tracking) and monetary supervising system in developed countries have minimized this scenario to happen.
So another more common theme with mild lose in business credit will cause - "
deflation". Since business owner lose their credits to borrow more money, or plan future expenses, so they cut their current expenditures. But the market did not changed immediately but slowly, and sometimes more commodities appear in the open market. (Companies may try to sell more commodities to customers in order to compensate future risk). Combining with the reduction of monetary supply (a big cause in this crisis) - not causing by the high interests rate, but simply because financial market went default in their promises, money simply clotting in the financial sectors (liquidity changes). Hence we have less money, and more products on the market - deflation is born. This scenario has its conditions that the economy is running although not in the top shape, but still 90% strong. (only a figure of speech, not real number)
So here comes the solution of the Kenyans' that since the problem is not enough currency, why not just increase them? Well, there are 2 sides of this policies. First, it is right that artificial increasing the supply of money is a way to solve the monetary clotting situation, as long as they are just restricted in financial sectors. Another side is that, increasing currency flow doesn't equal to printing paper. Currency should be backed by government debts (If the extra spending is not raised by other means like increasing taxes, however it's different from debts since government actually paid them back, someday
). Hence the increased currency actually comes from money borrowed from people. But wait! we encounter a question - If the money is borrowed from the people, and paid back to people (government expenditures), why is there more money on the market?
There are again 2 answers of why expenditure policies work. First is due to the process of "money creation" and the multiplier effect. Simply put, it's the effect that you give businesses more money, then they would want to expend their businesses hence borrowed more money from the financial market, and forcing the clotted money flowing out. Second answer is, bonds as a major part of debts are not only sold domestically. Other nations buy US government bonds in large quantities as well. Since US had been trade deficit for very long time. Many nations (epically in South and East Asia) accumulated enormous amount of foreign exchange reserves, as if these nations are US foreign dollars-deposits. And these nations are willing to buy the US bonds using the US dollars they have, as long as the interests of US government bonds are good enough, and the US government always maintains high credit rating and pays interests back in the past. (Won't default). Thus many less powerful country like Greece or Spain copied this method, with policies of expenditure as well, but their credits are not that good, hence although the bonds were issued, no one want to buy them. No one buy, no money flow, situation became worse and worse, and the their money became less and less creditable. Right now, these nations are suffered from the consequences. And recently we are observing the possible downgrade of US credit rating as well. Scared to become the next Greece? I think its a good reason why I think the government expenditure policies won't last long, and I said this again, other countries had suffered from it, Please be careful.
Y'know, people always talk about spending as if spending were sharply rising. Spending doesn't tend to go above 20% of GDP, low on the international scale and very, very low when you consider that it contains both a huge military and the worlds most inefficient healthcare system. The US by and large doesn't have a spending problem.
And I'd like to correct the data again. Not only the total expenditure of US exceeding 20% (over GDP) for a long time, it's even exceeding 30%, at current nearly 39%. (P.S. If you want to use "Government Consumption Expenditures and Gross Investment" as "cleaned up" number, it too over 25%, but it's NOT how other nations calculated their expenditures, for the purpose of compare to other nations I'll use the former, and explained more in next post). And if you are just talking about federal government, without local and state governments spending, than it too exceeding 26% in 2009. But the US total tax revenue is about 28% (Again, it's not a "cleaned up" number), hence its easy to say the difference of 10% in GDP must be compensate from somewhere else, it is mostly from raising debts, and increasing fees. If you want to know how big 10% of GDP is? The 2010 US GDP is 14.66 trillion. The accumulated government debts over GDP is closing 100% (96.3%) in 2010, and increasing at near 10% per years in the last 2 years. You can calculate how much interests needed to be paid at 3.5% with this amount of debts. You can find the detailed statistical data in
http://stats.oecd.org. (OECD is an official international organization with statistic database to developed countries.)
That been said, it's correct that US are not alone in this expenditure game. Most European countries has the same expenditures policies and mostly over 40% for a long time, even some over 50% (crazy French and Italian). And they are traditionally high tax revenue countries as well (over 30% closing 40%). Hence able to afford such expensive game. But compare to Asian countries, like India with 27% and China with 21% spending, and only nearly 20% and 18% of tax revenues. You will see it is a game that the western countries are borrowing the money accumulated in the eastern world because of trade deficit. Money running back to the importing countries through governments' debts/bonds from exporting countries, then through importing goods the money flows right back to exporting countries. Again and again, this process increases more and more debts and payment for interests of the western countries. But one day this game will come to an end (when default happens, like Russia in 1998). Especially when the Eastern world no longer trust the high debts in all western world that unable to pay back debts. (Again the seriousness about credits and faith) This phenomena was not recent and occurred recently in the crisis, but already running for decades. Right about the same time you heard made in China all over the street. And it's probably one of the factors causing the unbalance in financial market in the first place, causing the crisis. (International financial flow is quite unreliable, it has multiple currencies and complex financial instruments like the infamous derivatives.)
So we observed and traced some causes behind the recession, what does it tell us the role of inflation as an economy indicator? First, it's a combination of "production area", "financial area", and "market mechanism" effect. Hence the "unnatural change rate" of inflation means one or all of the relating areas are changing out of norm. The constant small inflation rate since the 1990s means there is a constant change somewhere, and most likely not only because of the economic growth, but the improvement of financial instruments thanks to the Internet and computer age (possibly create some "precise math models" for evaluating future risks as well). Also, in theory that if the growth of production and the growth of people are equal, and the business borrowed money from the financial market growth at the same rate, there should be no change in price. But since businesses tend to reserve a certain amount of revenue in case of emergency and the chasing of higher profits, they tend to earn more than they borrowed, hence the money is always in surplus as long as the revenue lost in default companies are comparatively less. (This is what most people called the "healthy economy")
We can see that as indicators - inflation can be caused by many factors, but if inflation becoming deflation, it means the causing factors of the phenomena were shifted. And the following direct stimulate by governments adding one more factors into it. And the sudden change from negative deflation back into positive inflation of this indicators so rapidly, implied that the factors changed again - and largely contributed by the extra factor - by the stimulate from government. Hence its not ONLY the phenomena I observed that worried me and leading to my conclusions, but the obvious effect in this indicator (and many others like the debt/tax, PPP shifting, financial clotting). The extra factor (government expenditure) causes another shifted in the already complex factors all contributed or related to current recession deeply worried me. The other factors as mainiac said are still there hidden and unknown, and most likely the artificial stimulate is what keeps the current economic "book" pretty. (So I am not rooting for immediately stopping of the government expenditure, since it will most likely end in disasters, but as I said many times, "
a plan for soft landing" is required right now, instead of keeping it till election days)
Mainiac mentioned the famous Phillips curve that describes the negative association of unemployment and inflation. But, it must under the conditions that other sectors are running as usual. (no change on other factors) The simplest explanation about the negative correlation is that since lay off workers don't have income, hence no money to spend, thus the ratio of money and commodities are lower - inflation drops. However IF it's true, it must not be far from "normal" conditions. (no change in financial market and production capability, etc). But this is purely mathematical model, and it needs to be tested. But there is little data from the economic history in the past, and they are almost all under different conditions. So it's hard to get a definitely answer from simply observations. (Some cases supported it, and some didn't not)
Newer generation of economic researches likes to experiment it using computation models. We see very complex results, and not a simple negative correlation. There are many conditions that inflation and wages can both going up, as in real world it happens in Spain. A simple scenario is that the drop of unemployment rate far off the production capabilities like in Spain as over 20%, it hits the commodities supply as well. And a government expenditure program grantee the unemployment workers as customers (high endowments). And the extra currency flow from the government expenditure supports the price to rise up. But the wage of normal working people are reducing from high taxes and their money flows to the unemployment people. And since the expenditure can not be stopped, or there will be riots on the street. Hence we observed the odd phenomena of increasing unemployment rate, increasing inflation, and dropping wages for working class.
Although I don't believe that the above situations already happened in US (maybe in small scale), but more likely that businesses owners are still insecure about the future, and setting up strict budgets and paying less wages. Also the financial market is not recovering enough for entrepreneurs to create new businesses. Thus all these combined keep the unemployment rate high. There are chances that the expenditure policies are having little effects. (How much is in effect is debatable) And the extra government spending could only flow into capital costs like long-term investment in building factories, and costs from importing goods, but not spending on raising the salaries. Hence businesses are more and more relying on foreign productions. It will lead to the strange money flows around the global like what I described above (still happening), and the inflation will goes up as maniac said due to the importing prices rise. And this is bad news for working class. You got paid less, and the price to buy things increases (not just luxuries, everyday stuffs as well). All because the domestic production area doesn't have the capability to absorb extra money supply, and the money flows outward to other nations.
Again I must say that I don't think the stimulate can last long (due to many reasons described above), and not because I observed this the shifting from deflation to inflation (just one of the reasons), but the fact that the stimulate is causing this side effect (phenomena) looks pretty on the surface ONLY, and not enough real effect on the positive side, like actually reducing the unemployment rate, etc. There are price to pay (credit drops, interests for debts, and loosing faith in financial market) in the future for keeping the face pretty. The negative it brings in my opinion is out weight the benefit we gain now. Raising debt ceiling is one of the policies not just for the keep running of further expenditure, but also a signal that US government is willing to raise debts and paying its debts in the future without actually going default. Despite the outcomes, the government will lose credit either way in the process since debts are already piling up whether you like it or not. (One is actually losing credit rating when default happens, and one is that people view the policies as a stalling tactic, and refuse to buy long-term bonds, losing faith. But only the former will make he ruling party look bad)
