    Camoflation



    In today's Wall Street Journal, Kevin Warsh, one of the Governors of the Federal Reserve, brings back the M word to justify borrowing $75 million pro-liquid and pro-growth dollars.:

    The New Malaise and How to End It

    After a cyclical boost early this year, the current state of the U.S. economy is unimpressive: modest growth, high levels of unemployment, stagnant wages, low levels of consumer and business sentiment, and volatile financial markets. Extrapolating from recent data, many predict only a middling recovery in the next several years. They call it "the new normal." I call it the new malaise.


    Usually, no one likes to talk about malaise, except the opposition party, of course. After President Jimmy Carter's well-received speech about tightening our belts, candidate Ronald Reagan gleefully beat Carter about the head with malaise. Even though Carter never used the term, the "malaise speech," and Carter's sweater, are now symbols of political failure.

    For a Fed Governor to use the term is striking, because malaise goes hand-in hand with the stagflation Carter inherited due to an expensive war (Obama has two), an energy crisis (Obama has that, too), and Nixon's suspension of the direct convertibility to gold (aka the Nixon Shock). Of course a key part of stagflation is inflation, which is not supported by the 1.1% rate under CPI-U. Besides, Walsh intends to make the case that we need pro-growth policies, not anti-inflation policies:

    Pro-growth policies include reform of the tax code ... more conducive to long-term investment. ... real regulatory reform ... succeed or fail. ... the creep of trade protectionism is anathema to pro-growth policies. The U.S. should signal to the world that it is ready to resume leadership on trade. ... deleveraging ... is not a pattern to be arrested, but good prudence to be celebrated. Larger, more liquid corporate balance sheets and higher personal saving rates are the reasonable and right responses to massive government dissaving and unpredictable government policies. The steep correction in housing markets, while painful, lays the foundation for recovery, far better than the countless programs that have sought to subsidize and temporize the inevitable repricing. ... the adoption of pro-growth fiscal, regulatory and trade policies ... lay the essential groundwork for greater, more sustainable prosperity. ... Federal Reserve is not a repair shop for broken fiscal, trade or regulatory policies. Given what ails us, additional monetary policy measures are poor substitutes for more powerful pro-growth policies.


    That was the justification, and here's the pitch:

    Last week, my colleagues and I on the Federal Open Market Committee (FOMC) engaged in this debate. The FOMC announced its intent to purchase an additional $75 billion of long-term Treasury securities per month through the second quarter of 2011.


    Correction: I had heard $600 Billion. Update: Apparently they're looking at an eight month plan. Though he did vote for it, another WSJ article makes it sound like Warsh is already backing away from the move. Talk about malaise ...

    Fed’s Warsh Skeptical Bond Purchases Can Boost Economy





    But back to stagflation. You can't have stagflation without inflation, which is measured by the Consumer Price Index (CPI), but consideration of the CPI is complicated because there are the CPI, the CPI-U, the CPI-W, the C-CPI-U and the CPE. Calculation of the CPI has been significantly revised in the past few decades. John Williams at ShadowStats has generated the chart above to show the divergence between the government's calculation of the CPI, and how he feels it was calculated about 1980, and how it should be calculated to really show the cost-of-living. Based on following Shadowstats, and other sites, and yes, my feelings, I felt that there is enough inflation in prices to say we are back in stagflation. Doc Cleveland has asked why he should believe Shadowstats instead of the normal CPI. The Bureau of Labor Statistics asked the same question back in 2008, and Williams responded here:

    The Traditional CPI Concept Has Been Politically Mauled. At the heart of the differences over CPI reporting is the way CPI is viewed or defined. My basic approach to looking at CPI inflation is from the standpoint of common experience and traditional expectations that the CPI measures the cost of maintaining a constant standard of living, that reflects costs out of pocket to get a products or services in hand, not some nebulous benefits estimated by the BLS of having to pay for an expensive new gasoline additive when filling a gas tank.

    The reason for the preceding is that inflation measures commonly are used as an indication of how much income has to increase, in order for living standards to be maintained, or of how much return is needed on an investment in order to stay ahead of inflation. Changing BLS methodologies have caused CPI inflation reporting to stray sharply from those needs

    I contend that most people view inflation as being much higher than currently reported by the BLS, due largely to those methodological changes over the decades that have moved CPI inflation away from basic, traditional reporting. Changes tied particularly to quality, weighting and definitional issues have moved reported inflation ever further from broad, common experience, with resulting reporting biases in the CPI that usually are to the downside. Consumers have a pretty good sense of where basic inflation stands, and whether or not they are able to make ends meet, let alone maintain a constant standard of living.

    One of the justifications in changing the CPI calculation was the idea that consumers were actually maintaining their standard-of-living by buying items that were cheaper, but just as good.

    What happened was that geometric weighting (replacing arithmetic weighting) was introduced for narrow product categories in the CPI. The categories were narrow enough to allow weight shifts between different types of steak, but the "mimicking" of the steak versus hamburger or steak versus chicken substitution was not possible based on geometric weightings, since steak, hamburger and chicken all were in different categories.

    Nonetheless, if steak prices were to rise, strapped consumers indeed likely would shift to cheaper meats, and such would be reflected in the broader weighting categories. The problem from the BLS standpoint, though, was that those weightings traditionally were recast only every ten years. So, the broad-category reweighting process was accelerated, with a reweighting in 1998, and, thereafter, reweightings were structured formally for every two years starting in 2002. This process moved the CPI closer to a fully substitution-based index.

    These approaches, in conjunction with other methodological changes ranging from increased use of discount-store surveying to shifting quality and hedonic adjustments, resulted in meaningful downside adjustments to reported annual CPI inflation of roughly 300 basis points (3%), of which 28 basis points currently is estimated by the BLS as the effect of geometric weighting. The period involved here, from the early-1990s to date, was dominated by efforts to address the Greenspan/Boskin contention that the CPI "overstated" inflation.


    In short, Greenspan saw buying store brands of shredded wheat, or going to discount plaza stores instead of the mall, as maintaining one's standard of living. Williams does not. I call it, "getting by."

    Geometric Weighting is a Mathematical Adjustment, Not a Model of Consumer Behavior. The BLS touts the use of geometric weighting in the narrow CPI categories as a way of measuring shifting consumer preferences based on changes in prices in related items. The weights that shift based upon price changes (relatively higher price changes end up with relatively lower weightings) do so by straight mathematical adjustment that the BLS once described as "mimicking" substitution effects. The shifts are not calculated based on any consumer surveying done, for example, as to how candy bar consumption would vary given relative price changes.

    The BLS claims support for using geometric weightings in the CPI, because everyone else does it. One also could argue that other sovereign statistical agencies, by their nature, have a tendency to want to reduce reported inflation as much as possible, as did Messrs. Greenspan and Boskin.

    On page 6 of the article, the authors argue that the shifting of weights within geometrically weighted categories does not affect a consumer’s standard of living, since the earlier arithmetic weighting always overstated cost of living, based on common academic thinking.

    "There is also no dispute among economists [except for John Williams as at least one] that the price index formula used in all of the basic CPIs prior to 1999 (called the Laspeyres formula) tends to overstate changes in the cost of living; specifically, the change in a Laspeyres is an ‘upper bound’ on the change in the cost of maintaining a [note: no "constant"] standard of living. …"

    "The Laspeyres answer is correct, however, only if the consumer is completely unconcerned with changes in price …"

    I would argue, to the contrary, that it is the so-called "overstatement" in the cost of living that enables the maintenance of a constant standard of living, where the consumer does not have to be concerned with changes in price. The BLS claims that with the geometric weighting, weighting shifts are measuring a "constant level of satisfaction," that there is no "declining standard of living" in the numbers, because geometric weighting is not applied to broad enough categories to allow hamburger substitution for steak.

    Nonetheless, the geometric weighting shifts have impact on a constant standard of living basis, as discussed above. Further, as mentioned earlier, the increased frequency of the reweighting of the broader categories impacts the standard of living on the steak to hamburger issue.


    As I see it, after what happened to Carter, no administration ever wanted to see that stagflation/malaise label  applied to them. (And I note that Palin is doing so right now). Greenspan reacted by redefining the calculation of inflation with a CPI that still moves up and down, but that would spit out more acceptable political numbers.

    But when some exurbanite shops at Stop N Shop instead of Stew Leonard's, or Giant instead of Whole Foods, that is a real change in standard-of-living. And when you buy cheap socks at the Dollar store instead of better ones at Sears or JC Penney, or even better ones at American Eagle, that is a real change in standard-of-living. And when the box of crackers you bought last month is now 10 ounces instead of 12 ounces, that is change, not maintenance, of standard-of-living. And while it might not be a bad thing to buy store brands instead of over-priced name brands, it is a change, it costs somebody profit somewhere, and it should be measured.

    So you're saying the big banks are accepting a real return of negative 6 to 8% on those trillions in Treasuries and excess reserves they're holding, and artificially keeping down the price of stocks relative to bonds in general?

    I'm not saying it CAN'T be true, bankers do seem phenomenally stupid, but still, there are limits...

    Okay, I'm in. I'm investing all my savings in cans of spam!


    Actually I recall the change in the way the CPI is weighted, back in the 1990s, and I disliked it at the time, but I recall it operating just in the opposite way from what you say.

    The justification for changing the CPI was that the quality of good should be taken into account. If the price of a mid-list PC hovered at around $1000 for six years, but that mid-list PC doubled in processer speed every eighteen months (so that at a $1000 PC in 2000 was about 16 times faster than a $1000 PC in 1994), that should be construed as prices falling. There are problems with that, but the PC example realistic. The machine that cost a grand in 1994 really did cost only six hundred bucks in 1996. And the point is that the difference in the value of goods now gets paid more attention, not less, in the CPI.

    I will freely admit that I view Shadowstats as fringe. "Adjusting" 1.1% inflation to 8.5% requires some big, big evidence. And although I'm no slave to conventional wisdom among economists, I'd like to see other professionally competent parties using (and explaining) Williams's numbers before I take them as solid.

    And I defy Shadowstats' appeal to consumers' gut feelings. The basic rule of psychology is that the price of whatever you want to buy always seems too high. If I went out shopping for a house today, at the rock bottom of the real estate market, I would feel that the price of a house was a lot higher than I would like, because it's my money. This is precisely the trick that allowed the right-wing Wurlitzer to persuade people that Obama had raised their taxes: it always feels like your own taxes are going up.

    Even so, I do most of the grocery shopping in my household, and prices have been pretty steady. I would really notice prices going up eight percent this year. And that just didn't happen.


    Doc, if I may butt in, I think the mechanics of hedonics works both ways: inflation gets overstated as regards technological products - it doesn't adequately take into account the improvements in products over time, and inflation gets understated for stuff like food where it doesn't take into account the loss in quality across substitutions - prime steak gets replaced by faeces invested hamburger meat.

    As a corrollary, as inequality rises, the whole idea of a 'typical basket of goods' becomes nonsensical. Food and energy are a huge part of lower-middle class consumption and a tiny part of upper-middle-class consumption. So headline inflation numbers will tend to paper over differences in effects as the poor face real hardship at rising commodity prices and the rich feel no effect at all thanks to vast improvements in tech products.

    Not that i'm endorsing shadow-stats or standard CPI numbers, it's just the debate about what the REAL inflation rate is has lost its hold on, well, ... reality.

    Just my pretty amateur take on this hard stuff...


    Okay, fair enough. And that was my (obviously amateur) objection to rejiggering the CPI at the time: that it disguised the *minimum* cost of living. Obviously an economy in which the cost of luxuries falls and the cost of necessities rises is not holiding the course.

    That said, 1) the financial powers-that-be have powerful reasons to overstate, not understate, inflation. And as you said, if real inflation were over eight percent, all of the bankers would be behaving very differently.

    and 2) the groceries thing is just a fantasy.


    Williams addressed that computer example in the linked article:

    Getting more into the hedonics area, I’ll get personal. I use two personal computer systems purchased about 10 years apart for roughly the same price in nominal terms, about $800. While the most recent computer has greater memory and is faster than my old system, both systems generally perform the same tasks for me. Based on the BLS’s adjustments to computer prices, in terms of quality/hedonics, my old system should have been replaceable for about $85.00 in current dollars, which was not doable. I do have a nicer picture screen, with the new system, but I also unexpectedly had to buy a new printer, because the new system was not able to function with my antique work-horse printer. The new computer also was not able to use certain key programs that had not been rewritten to the standards of the new system. How does one compare and value such systems in the CPI? While some quality adjustment in the case of computers seems appropriate, I argue it has been heavily overdone from the practical standpoint of the average consumer.

    My wife and I always shop together. Around 2001, we'd wander into Shaws and buy the best of everything. Since then we've been torn between a steady search for cheaper and cheaper ways to stretch the dollars, and a search for real food on the shelves. I don't think the 8.5% is across the board, but real food is getting very expensive.

    Of course Williams is fringe. So is Roubini. But during the crash of 2008, Roubini suddenly became a prophet, and The Sunday Times found some folk that agreed with Williams:

    That's the dark thinking beyond what is known as Pollyanna creep, a phrase coined by an economist named John Williams. He runs a website called Shadowstats.com that trades in the idea that some key US government statistics have become so optimistically misleading as to become useless. Now, this might sound a bit like a plotline from one of those Matrix movies - we're all living in an illusion to inure us from dire reality. But given what's gone on with Freddie and Fannie, Lehman, Merrill, AIG, Washington Mutual and more, it doesn't sound so fringe.

    Indeed, over the past few years, some of Mr Williams's views on economic indicators - the consumer price index, in particular - have been echoed by better-known and leading investment community figures, such as the bond investor Bill Gross, the strategist Stephen Roach and James Grant.

    “The numbers are misleading, and Wall Street uses the numbers to help sell their products,” says Mr Williams, whose chief bugaboos, in addition to the CPI, are GDP and unemployment rates. “Recently, I'd contend that what we've been getting is absolutely junk on the GDP,” he says, despite recent official figures that US GDP grew 3.3 per cent in the second quarter. “There's no question that we're in a recession and probably have been in one since the last quarter of 2006. It didn't start with the housing mortgage crisis.”

    According to Mr Williams, all the big measures have had their methodologies revised over the past few decades to paint the US economy in the best possible light. However, he says, changes in methodology were always spelt out at the time - with rationales for doing so - thus it's not as though this has gone on in the dark of night.

    In his recently published and rather depressing book, Bad Money: Reckless Finance, Failed Politics, and the Global Crisis of American Capitalism, one-time Nixon White House advisor Kevin Phillips discusses Pollyanna creep as part of an era of “bullnomics: the pied-piping of America toward a misleading financial ideology [the efficiency and reliability of markets], buttressed by a spectrum of dubious thinkers, doctrines and enablers”. In popular culture, he notes, this coincided with a surge in self-help and get-rich media, perhaps best exemplified by the 2007 bestselling book, The Secret, which effectively argued that you can make money by imagining it.

    More practically, he writes that some of the biggest changes to CPI calculation happened between 1997 and 1999 “while the public and the politicians were preoccupied by bull market euphoria and the actions in Congress to impeach Bill Clinton”. In their effort to reduce social security outlays - and buttressed by a belief that CPI in fact overstated inflation - Alan Greenspan and others implemented some controversial modifications that factored in such issues as “hedonics”: an abstruse way of measuring increased satisfaction from goods. (Example: as described in a 2005 Wall Street Journal story, a specialist in the Bureau of Labor Statistics (BLS), which compiles the CPI, adjusted the price of a $329.99 TV down to $194.99 after concluding that an improvement in the quality of its screen over a previous model of the same size was worth at least $135. The TV still cost $329.99 retail, but the CPI recorded it as being worth nearly 30 per cent less.)

    Pollyanna creep did not arise from any single decision, nor was it the product of a conspiracy. It's not unlike the advent of “earnings before one-time items” reporting in the private sector - an accountancy practice virtually unheard of 20 years ago but which has become commonplace and presents a rosier view of a company's performance. These practices are accepted because they suit the purposes of all involved. But that doesn't make them the right thing to do.

    Four years ago, the bond investor Bill Gross, of Pimco, made waves when he published a newsletter calling the CPI an “haute con job”. He recently penned an update, arguing that it was hard to reconcile America's reported CPI rates with the much higher rates from a basket of 24 other countries. Noting that he does not write for a “conspiracy blog,” Gross went on: “Just as many in the global economy are refusing to mimic the American-style fixation with superficialities in favour of hard work and legitimate disclosure, investors might suddenly awake to the notion that US inflation should be, and in fact is, closer to worldwide levels than previously thought.”

     


    The CPI is to my mind an artificial term dreamed up by administration economists and mathematicians to justify whatever god awful economic policy they come up with.


    Not sure where to start here.  I suppose that first I should note that the way this has been written has an overtone of conspiracy that I don't think is really necessary.  It could have been avoided by a more grounded talk about when the CPI has been adjusted, who argued for it, who argued against it, etc.  It's really not a conspiracy, but it sort of sounds that way here.  For some context, the Greenspan argument had to do with the fact that SS COLA is tied directly to the CPI.  If the CPI was overestimating inflation, then it follows that COLAs were more expensive than they needed to be.

    Second, this has been argued to death, but I suppose we shouldn't let that stop us.  The other side of the argument, what you'll hear from BLS, goes something like this:

    The Bureau of Labor Statistics explains;

    In contrast to the fixed quantity weights of the current CPI formula, the geometric mean estimator ... implies that consumers can alter the quantities of goods and services they buy, albeit within the narrow range of a CPI category, when the relative prices of those goods and services change. It is, in part, this property of the geometric mean estimator that led to the Boskin Commission recommendation of its use in the CPI.

    In other words, the crime of a geometric weighting scheme is to assume that people change their behavior when prices change.

    The supposed downfall of attempting to account for substitution effects in the CPI is that you'll end up substituting all the way down to dogfood.  Except that keeping the geometric weights within narrow categories doesn't allow for broad substitutions across categories.  Also: Is there any credible evidence that an invisible deterioration of the standard of living is actually happening?  Krugman reminds us that the answer to this question is "no."  So, what exactly is the grounding for this argument?  I understand what Mr. Williams' motivation is here: He sells alternative data.  If his data is not appreciably different than those from official sources, what does he have to sell?

    Third, we are remiss if we discuss how inflation affects prices while ignoring how it affects wages.  For this, I'll turn to Dean Baker, who wrote a book on this very issue:

    The other point is that you do not just get to change the CPI and leave the rest of the world in place. If the CPI substantially overstates inflation, then everything we think about the world is very different. For example, a 1.0 percentage point overstatement means that real wages and incomes have been rising by 1.0 percentage points more rapidly than our data show. This enormously changes our assessment of the future and the past. It would imply that us middle income types grew up at a standard of living that is lower than the current poverty level.

    It also changes our assessment of the future. If wages and living standards have been rising by 1.0 pp more rapidly than we thought, then presumably they will continue to rise by 1.0 pp more rapidly than currently projected. This means that our children and grandchildren will be far richer than we imagined possible with current projections.
    Such future prosperity may make current concerns about the deficit seem rather silly. Why should be care if our grandchildren will have to pay another 10 percent of their income in taxes, if their standard of living will be 4 times as high current standards of living?

    In absence of any real evidence of the posited substitution spiral, we get some contorted arguments about buying generic versus name-brand shredded wheat as a quality of life issue.  It's not.  Choosing not to pay the bills for Kellogg's ad department is not a quality of life or standard of living issue, at least not a serious one.  It's worth noting here that there are at least one billion people living on this planet who would love to have this type of problem.

    Also, you close with:

    And while it might not be a bad thing to buy store brands instead of over-priced name brands, it is a change, it costs somebody profit somewhere, and it should be measured.

    The changes in profit are measured by the revenue streams of the relevant firms.  That's where it is measured and where it should be measured.  Capturing changes in revenue streams of individual firms, which may or may not be at all related to substitution effects induced by real changes in the overall price level, are not what the CPI is for.

    At the core, this is an argument about methodology, but I'll again defer to Baker about who's really trying to be an honest broker here:

    On this story, I argue that we should leave the call to the umpire, in this case the Bureau of Labor Statistics (BLS), the agency that constructs the CPI. Of course BLS can and does make mistakes, but they have generally been an honest broker on this issue. When economists have presented solid research showing understatements or overstatements in the CPI, BLS has examined the issue and sought to make the appropriate adjustments (We were very fortunate that the Katherine Abraham, the commissioner in the 90s, resisted the political pressure to implement a politically convenient "fix" of the CPI.) I have my own criticisms of the ump, but at this point, I'm going to defer to the ump's call over the anecdotes of the CPI critics.

    Hence why you do not hear scores of economists, especially the ostensibly "liberal" set, screaming about how the CPI is a deceptive measure of the standard of living.  It's not perfect, but this is because what it is trying to measure is complex.

    EDIT: Also, RE: stagflation - even if you prefer a methodology that places inflation at a higher rate, where is the supply shock?

    EDIT #2: From BLS, via Wikipedia:

    Some critics believe that changes in CPI calculation due to the Boskin Commission have led to dramatic cuts in inflation estimates. They believe that using pre-Boskin methods, which they also think are still used by most other countries, the current U.S. inflation is estimated to be around 7% per year. The BLS has demonstrated that these beliefs are based on misunderstandings of the CPI. For example, changes made since the Boskin Commission have lowered the measured rate of inflation by less than 0.3% per year, and the methods now used are commonly employed in the CPIs of developed nations.[8]


    "In politics, nothing happens by accident. If it happened, you can bet it was planned that way." - FDR

    Why did you not hear scores of economists predicting the economic collapse of 2008? Actually I did, but they were all fringey guys like Roubini and Williams. As for BLS being an honest broker, do you really believe the unemployment rate is only 8%? Somewhere in the BLS is a guy who answers to the administration.

    As far as the Dean Baker stuff, remember I'm talking about stagflation not inflation.


    Roubini wasn't that fringe, and you did hear plenty of people predicting the collapse of then housing bubble. Alan Greenspan and his ilk spent a good part of those years denying the existence of a housing bubble. he wasn't arguing against the existence of that danger because no one believed in that danger. Quite the reverse. And anyway, read Atrios's blogging from 2007 and 2008 to see the perfectly orthodox and mainstream prophecies of doom.

    The 2008 collapse was not something no one was predicting. It was "something no one could have predicted" in the same way that deficits from the Bush tax policies could not have been predicted, or the quagmire of the Iraq war could not have been predicted, or the results of a category 5 hurricane directly hitting New Orleans. Not something entirely out of the blue, but the uglier-than-expected outcome of something that any fool could say would get ugly.


    Umm, I did.  Among them Baker (who called it WAY before anyone else, BTW) and Krugman.  And Stiglitz.  And many others.

    I believe the unemployment rate is 8% as measured.  Donal, this is not about what we believe.  If you want to debate the methodology behind measures, fine.  My point is that this debate has occurred and you're completely blowing off the other side of the argument.  You write your post as if Greenspan did this behind closed doors with clandestine political motivations.

    So, is U-6 higher?  Yeah, it is.  Do some economists think that's a better measure of unemployment?  Yeah, they do.  Are there open, honest debates about the models and methodology here?  Yeah, there are.  Are you addressing ANY of that in your statement here?  No, you are not.  All of the same things that can be said about the unemployment survey and subsequent estimates can be said about CPI.  You seem to prefer a conspiracy.

    As for the Baker "stuff" - Baker, BTW, called the bubble back in 2002 using the Case-Schiller data - you haven't analyzed stagflation here AT ALL.  Stagflation is what?  Concurrent inflation and unemployment, which changed minds about economic theory basically because that wasn't supposed to be possible.  But what was the root cause?  A supply shock.  Can you answer whether you see evidence of a supply shock currently?

    Futhermore, I answered you with Baker on the CPI because a.) He was there, actively engaged in those debates b.) He's a trained economist who actually knows these models and measures inside and out AND c.) He's disciplined enough to remember that partial analysis is bogus.  Hence him having to remind the CPI critics that inflation doesn't just affect prices, but also wages.

    Seriously, if stagflation = inflation + unemployment, then you cannot talk about stagflation without talking about inflation.  In fact, that's what your whole post is about: The CPI, which attempts to measure inflation.  If that has nothing to do with stagflation, then why is that what your whole post is about?

    And I can be just as flippant about dismissing whole lines of argument on the basis of suspect motivations.  In fact, I did: Williams' has a vested interest in selling alternative data.  That's another component that you didn't respond to.


    If you keep up with the attitude, there will be a lot of components I don't respond to.


    My attitude is that the argument you've presented has some serious flaws, which I've tried to detail based on substance.  Your attitude is to apparently to just brush those critiques aside.  You can respond to them or not.  I trust that whether you do or not will be apparent to the readers of this post.

    Seriously: I left a long comment with a number of substantive critiques.  Your response to that was a quote from FDR, that economists didn't call the bubble (they sure did) and that Dean Baker's "stuff" was about inflation, not stagflation (which doesn't even make sense, nevermind that the Baker article I linked was precisely about the the events regarding the altering of CPI in 1990s that you spent an entire post on).  And I'm the one with an "attitude"?


    Where is the supply shock? For decades we had an economy based on $20 or $30/bbl oil. In the past three years oil went from $60 to $140, back down to $50 and is now brushing up against $90. How much shock do you need to see?


    Oil is dollar denominated.  You're claiming very high inflation, which causes the nomimal (read: NOT REAL) price of a barrel of oil to rise.  I need to see a shock that isn't substantiated on conflicting arguments.


    Nominal and real track pretty closely in that time period.

    http://en.wikipedia.org/wiki/File:Brent_Spot_monthly.svg


    Can you not read the part of that graph where it says that the figures are calculated based on the CPI, which your whole post has brought into question?  Can you honestly not see the inherent conflict between these arguments?  Seriously, how can you question the methodology behind CPI, then turn around and use it to try to prove your argument?
