Waldman on "Econometrics, open science, and cryptocurrency"

Econometrics, open science, and cryptocurrency by Steve Randy Waldman

Mark Thoma wrote the wisest two paragraphs you will read about econometrics and empirical statistical research in general:
You are testing a theory you came up with, but the data are uncooperative and say you are wrong. But instead of accepting that, you tell yourself "My theory is right, I just haven't found the right econometric specification yet. I need to add variables, remove variables, take a log, add an interaction, square a term, do a different correction for misspecification, try a different sample period, etc., etc., etc." Then, after finally digging out that one specification of the econometric model that confirms your hypothesis, you declare victory, write it up, and send it off (somehow never mentioning the intense specification mining that produced the result). 
Too much econometric work proceeds along these lines. Not quite this blatantly, but that is, in effect, what happens in too many cases. I think it is often best to think of econometric results as the best case the researcher could make for a particular theory rather than a true test of the model.
What Thoma is describing here cannot be fixed. Naive theories of statistical analysis presume a known, true model of the world whose parameters a researcher need simply to estimate. But there is in fact no "true" model of the world, and a moralistic prohibition of the process Thoma describes would freeze almost all empirical work in its tracks. It is the practice of good researchers, not just of charlatans, to explore their data. If you want to make sense of the world, you have to look at it first, and try out various approaches to understanding what the data means. In practice, that means that long before any empirical research is published, its producers have played with lots and lots of potential models. They've examined bivariate correlations, added variables, omitted variables, considered various interactions and functional forms, tried alternative approaches to dealing with missing data and outliers, etc. It takes iterative work, usually, to find even the form of a model that will reasonably describe the space you are investigating. Only if your work is very close to past literature can you expect to be able to stick with a prespecified statistical model, and then you are simply relying upon other researchers' iterative groping.

Yellen


Yellen: Monetary policy not the right tool to curb financial excesses by Ylan Q. Mui

"...Yellen argued that those weapons would likely be more effective than the blunt tool of monetary policy. To make her point, she rebutted a common criticism that the Fed primed the stage for the Great Recession by waiting too long to raise interest rates, allowing home prices to rise unabated and encouraging investors to pile on risk.

Yellen conceded that policymakers “failed to anticipate” the ensuing global financial crisis but also argued that monetary policy would have been “insufficient” to address the problems that caused it. Higher rates would not have beefed up regulation or increased the transparency of the exotic new financial instruments at the heart of the crisis -- or the firms that helped generate them.

In fact, Yellen said that raising rates would likely have caused greater unemployment, which would likely have led to more people defaulting on their debts."

How does John Taylor respond?

dsquared's comment to Robin's Crooked Timber post:
"As far as I can tell, nothing really important in Piketty’s book depends on the capital controversy; it’s actually a book about wealth rather than capital in the technical sense. It’s just a bit irritating for people who happen to know that his use of “capital” and connected marginal concepts is wrong.

Mark Thoma’s classic crack — “I’ve learned that new economic thinking means reading old books”

We don't need new ideas, we need "old" ideas.

New Thinking and Old Books Revisited by Krugman
I learn from Francesco Saraceno that some people are attacking me for, as they see it, defending an economic orthodoxy that has failed. It’s kind of an odd place to find myself, given how critical I’ve been of the way the economics profession has dealt with the crisis. But it’s not entirely unfair: I am quite skeptical of people whose response to the sorry state of affairs is to declare that what we need is a whole new field.

Why my skepticism? I’m all for new ideas that add to our understanding. But ideas like that aren’t easy to come by! Mark Thoma’s classic crack — “I’ve learned that new economic thinking means reading old books” — has a serious point to it. We’ve had a couple of centuries of economic thought at this point, and quite a few smart people doing the thinking. It’s possible to come up with truly new concepts and approaches, but it takes a lot more than good intentions and casual observation to get there.

So, for example, what do I say when I read something like this from someone who apparently considers himself a bold rebel against orthodoxy?
“Rational thinking is an important aspect of human nature, but we have imagination, we have ambition, we have irrational fear, we are swayed by other people, we get indoctrinated and we get influenced by advertising,” he says. “Even if we are actually rational, leaving it to the market may produce collectively irrational outcomes. So when a bubble develops it is rational for individuals to keep inflating the bubble, thinking that they can pull out at the last minute and make a lot of money. But collectively speaking . . . ”
My answer, to put it in technical terms, is “Well, duh.” Maybe grad students at some departments, who are several generations into the law of diminishing disciples, really don’t know that rational behavior is at best a useful fiction, that markets aren’t perfect, etc, etc. But does this come as news to Robert Shiller? To Ben Bernanke? To Janet Yellen? To Larry Summers? Would it have come as news to Irving Fisher or Walter Bagehot?

The question is what you do with this insight.

There is definitely a faction within economics that considers it taboo to introduce anything into its analysis that isn’t grounded in rational behavior and market equilibrium. But what I do, and what everyone I’ve just named plus many others does, is a more modest, more eclectic form of analysis. You use maximization and equilibrium where it seems reasonably consistent with reality, because of its clarifying power, but you introduce ad hoc deviations where experience seems to demand them — downward rigidity of wages, balance-sheet constraints, bubbles (which are hard to predict, but you can say a lot about their consequences).

You may say that what we need is reconstruction from the ground up — an economics with no vestige of equilibrium analysis. Well, show me some results. As it happens, the hybrid, eclectic approach I’ve just described has done pretty well in this crisis, so you had better show me some really superior results before it gets thrown out the window.

Oh, and if you think you’ve found a fundamental logical flaw in one of our workhorse economic models, the odds are very strong that you’ve just made a mistake.

Does this mean that nothing should change in the way we teach economics? By no means — it’s quite clear that the teaching of macroeconomics has gone seriously astray. As Saraceno says, the simple models that have proved so useful since 2008 are by and large taught only at the undergrad level — they’re treated as too simple, too ad hoc, whatever, to make it into the grad courses even at places that aren’t very ideological.

Furthermore, to temper your modeling with a sense of realism you need to know something about reality — and not just the statistical properties of U.S. time series since 1947. Economic history — global economic history — should be a core part of the curriculum. Nobody should be making pronouncements on macro without knowing a fair bit about the collapse of the gold standard in the 1930s, what actually happened in the stagflation of the 1970s, the Asian financial crisis of the 90s, and, looking forward, the euro crisis.

I’d put my oar in for history of thought, too. Watching highly trained economists reinvent old economic fallacies suggests to me that there would be real payoff to requiring that students have some idea how the current leading doctrines got to where they are.

But must we reconstruct all of economics? No. Most of what we need, at least for now, is in those old books.

Yellen-Greenspan

Izabella Kaminska at FT Alphaville:

Greenspan’s dilemma revived, by Izabella Kaminska: Deficit continues to be a dirty word in the US..., whilst the idea that the US is an unsustainable deficit spender increasingly propagates in mainstream circles.
But, as Ethan Harris at Bank of America Merrill Lynch shows on Monday, nothing could be further from the truth. In reality the US deficit is contracting at a relatively speedy rate... And, bar the employment situation..., all of this comes in the context of an ever more quickly reviving economy...

Which leaves the following as the most notable point being made by Harris, in reference to the natural unemployment rate (NAIRU):
    If inflation persists below 1.5%, we would expect the interest rate forecast to drop further. We also expect the FOMC to cut its unemployment rate guidepost for hiking rates from 6.5% to 5.5% or lower. Ultimately, the Fed may decide to “overshoot” the inflation-neutral NAIRU to force inflation back up to target.
This in itself could become ever more crucial in the months to come. In short, it echoes exactly the same sort of dilemma Alan Greenspan faced all the way back in 1996. Do you raise rates despite little obvious inflationary pressure and risk stagnating growth? Or do you give the notion of a “new economy” — the idea that technological change is fuelling a boom in productivity and alleviating inflationary pressures — the benefit of the doubt?

Janet Yellen, it must be said, is uniquely positioned to make that call if she is confirmed. Not only was she there the first time around, she may have had more input on Greenspan’s ultimate decision than many remember. Call it something akin to mea culpa dotcom crash hindsight.

The Great Recession

The Great Lesson from the Great Recession by Mark Thoma

But we didn't avoid the biggest mistake, which is to try to pop a bubble by causing a recession. 
In fact the conduct of monetary policy on the eve of the Great Depression and the Great Recession are eerily similar. Monetary policy was tightened to such an extent that the yield curve became persistently inverted in January 1928, 19 months before the Great Depression started: 
http://research.stlouisfed.org/fred2/graph/?graph_id=108333&category_id=0 
Similarly monetary policy was tightened to such an extent that the yield curve became persistently inverted in August 2006, 16 months before the Great Recession started: 
http://research.stlouisfed.org/fred2/graph/?graph_id=75581&category_id=0 
So far from being very different, it's "deja vu all over again".
The bank panics in the Great Depression started in small rural banks, so it was far easier to totally ignore it and to allow things to fester for a couple of years in those days. It wasn't until big urban banks started to fail, like the Bank of the United States in New York City in 1931, that the powers that be started to notice that there was financial crisis going on in their midst.
This time the banks are far larger, and thus harder to miss, especially since with the help of Bernanke and Paulson, they informed the Congress that they were holding the nation's economy hostage unless a TARP ransom was paid. So I'm not sure this is a sign of improved economic policy as much as it is a sign of more deeply entrenched and powerful interests demanding and getting first and best servings near the beginning of our depression, while the rest of us have to wait interminably for poor seconds. 
From 1933-37 the US pulled off the greatest economic recovery in history. Real GDP growth averaged 9.5% and unemployment dropped from 20.9% to 9.2%. And we know based on analysis by E. Cary Brown, Christina Romer, Barry Eichengreen etc. that the contribution of fiscal policy to the recovery was minor. Thus this was primarily a monetary policy led recovery. 
Why did monetary policy work so well back then despite the incredible odds against it?  Because by taking the country off the gold standard in April 1933, and allowing the price of gold to rise from $20.67 an ounce to $35.00 an ounce by January 1934, FDR effectively set a Price Level Target (PLT). This PLT was high enough to attract a large gold inflow from abroad which the Treasury monetized by issuing gold certificates to the Federal Reserve. The monetary base skyrocketed upward, reaching a maximum year-on-year rate of increase of 23.0% in February 1935, which essentially was the QE of its day. The economic recovery only came to an end when the decision to start sterilizing gold inflows in December 1936 meant prematurely removing the punch bowl, leading to the 1937 Recession. 
That was very much unlike our recent experience, where no new target has been set (it's just the same old 1-2% inflation rate target, yawn) and, until QE3, monetary base expansion has come in fits and starts. 
It seems to me, rather than evolving over time, monetary policy has devolved back into the "lunged" fish-like gold standard era ancestors from which it evolved, and seems utterly content to wallow in the miasmic swamp from which it came.

KHAAAAAN!

commenter Denim at Economist's View:
Basically the New Deal was slowly bled in order to replace it with fierce dog eat dog competition among us wage slaves and small businesses via deregulation and turning a blind eye toward predatory pricing by the behemoths. That began with Jimmy Carter's Alfred E Kahn inflation and deregulation guru. All Presidents thereafter adopted this meme. All.

Yellen for Fed chair (Romer would be better!)

Larry Summers is the Front-Runner? WTF? by Thoma

and via commenter Sadowski:

Larry Summers is unqualified to be Fed chair by Scott Sumner

Just shoot me by Scott Sumner

Do Larry Summers and Janet Yellen Disagree About Monetary Policy? by Yglesias

In the financial crisis behind-the-scenes books Summers comes off better than I would have guessed. He sided with Romer on somethings. He wanted to nationalize Citigroup. He has argued for more fiscal policy stimulus.

Scott Sumner on blogs:
Saturos asked me for areas where my views have been changed by bloggers.  I’d rather talk about bloggers who have influenced me.  MR is probably my favorite blog, but I’d single out 4 bloggers who often get me to rethink my assumptions; Bryan Caplan, Robin Hanson, Matt Yglesias and Paul Krugman.  In all four cases they often make claims with which I disagree.  After reading their arguments I still often disagree.  But I find that they seriously undermine my confidence in my own position.  That is, I find it hard to refute their arguments, even if the conclusion seems annoying.  Once and a while I am converted. 
In some cases (such as the Cowen and the Tabarrok/Yglesias examples mentioned by Noah Smith), I have vague and free-floating intuitions that suddenly solidify into strong coherent arguments.  In others I go from strongly supporting X, to having some doubts.  It’s rarely a 180 degree turn. 
I’d add that Yglesias influences me more than Krugman for two reasons.  First, he focuses more on narrow issues that interest me, such as progressive consumption taxes. (Has Krugman ever mentioned those?)  Yglesias does read my blog, and seems to be more a part of the monetary policy conversation as I see it.  Krugman almost never even nods to the monetary offset point.  He has a wider audience.  And second, Yglesias seems to come to positions from a more ideologically neutral perspective than Krugman.  That allows me to dismiss some Krugman arguments as “biased,” even if I really should not be doing so. 
I probably shouldn’t have started this list, as I don’t know where to stop.  I like lots of the MM bloggers, but tend to already agree on most points.  Ditto for Ryan Avent.  Other talented bloggers like DeLong I don’t read as often, purely due to lack of time.  I’m always running behind these days.  Even the two teenage econ bloggers (Soltas and Wang), have influenced me on a few points.
 I wouldn't be that surprised if Summers was relatively good as Fed chair. But then again I wouldn't be that surprised if he was complacent as Bernanke was.

MMT and never say never

Warren Mosler, a Deficit Lover With a Following by Annie Lowrey
Still, even for those with some knowledge of economics, the tenets of the modern monetary theory can make your head spin. The government does not tax its citizens to pay for federal spending. It taxes them to ensure they use the dollar and to help to regulate demand. Since the government prints the dollar, it can never run out of money and it need never balance its budget, not even to prevent the crowding out of private investment when the economy is humming along.
I have a problem with the hyperbolic claims. It's Keynesiansism with some suspect claims tacked on employing the word "never." Perhaps it is a straw man. But they are right that we shouldn't be worrying about the deficit and that fiscal policy could take the place of monetary policy. The problem is politics and a corrupt elite. But monetary policy has offest fiscal austerity to some extent so I don't understand the MMTers who denigrate the focus on monetary policy. The more mainstream economists are right to focus on it.

Reconciling Modern Monetary Theory with the Wisdom of Mark Thoma by Dean Baker

Stephanie Kelton has a comment.
On a different point: MMT supports tax increases and/or spending cuts to address demand-pull inflation. No different from, say, Abba Lerner or Marriner Eccles. 

The real point of departure for MMTers and textbook Keynesians is, I think, very much bound up in the loanable funds theory of the interest rate (the former rejecting and the latter accepting it). From that follow all sorts of differences re: fiscal sustainability. Scott Fullwiler has written brilliantly on this.

Yes but the Stimulati were not running things.

ORIGINS OF THE CRISIS by Chris Dillow
After 1997, Asian economies wanted to run big current account surpluses, either as a policy of export-led growth or in order to rebuild reserves depleted by the 97 crisis. By definition, this meant they were net savers, which put incipient downward pressure upon global interest rates. In a parallel universe, these high savings might have financed a boom in real capital spending in the west. But because firms couldn't see good investment opportunities, this didn't happen.Instead, the lower interest rates fuelled a housing boom and the hunt for yield led to strong demand for mortgage derivatives. These bubbles in housing and derivatives then burst, giving us the crisis. 
In this way, we've seen what Marx saw in the 19th century - that a lack of profitable opportunities in the real economy pushes people down "the adventurous road of speculation, credit frauds, stock swindles, and crises." 
I say all this as a corrective to a common view on the non-Marxist left - that our economic problems are due to greedy bankers and to austerity. But this is nothing like the whole story. This has been a crisis of real, and not just financial, capitalism - which is why it is so intractable

IMF Urges Repeal of 'Ill-Designed' Spending Cuts by Mark Thoma

In case you missed this, the IMF estimates that economic growth would be nearly double what it is now without the "excessively rapid and ill-designed" government spending cuts:
IMF Urges Washington to Repeal ‘Ill-Designed’ Spending Cuts, Reuters: The International Monetary Fund urged the United States on Friday to repeal sweeping government spending cuts and recommended that the Federal Reserve continue a bond-buying program through at least the end of the year. 
In its annual check of the health of the U.S. economy, the IMF forecast economic growth would be a sluggish 1.9 percent this year. The IMF estimates growth would be as much as 1.75 percentage points higher if not for a rush to cut the government's budget deficit. ... 
"The deficit reduction in 2013 has been excessively rapid and ill-designed," the IMF said. "These cuts should be replaced with a back-loaded mix of entitlement savings and new revenues." 
The IMF warned cuts to education, science and infrastructure spending could reduce potential growth. ... 
The Fund recommended that the U.S. Federal Reserve keep up its massive asset purchases at least through the end of the year to support the U.S. recovery, but should also prepare for a pull-back in the future. ...
The recovery of output and employment didn't have to be so slow. I'm not saying that reversing these policies (or replacing them with more aggressive fiscal policy measures) would have brought miracles, it was going to be a difficult recovery no matter what polices we pursued. But we certainly could have done better than we did, particularly on the fiscal policy front.

Triffin dilemma

I agree with many of the economic ideas put forward by Yglesias, Thoma, Krugman, DeLong and Baker (among others like Waldman and Bernstein and others on my bloglist). I've  learned a great deal from them and not just about economics, but about other things that surround the dialogue of econblogging. How to argue and have sense of humor and good attitude, etc. I almost always agree with them on the economics and usually on the politics which is much more subjective.

So it's illuminating to me when they disagree, which is rare, or on when they have differences of emphasis. It's not a competition of course it's just interesting to learn how these smart guys think.

For one thing they all want full employment. That's not the goal of glibertarians or cranks like Tyler Durden at Zero Hedge who's main focus is that it's all a scam to give banks money and America's days are numbered.

Anywaying it's interest how Dean Baker emphasizes the trade deficit and the strong dollar policy of Summers-Rubin, while DeLong and Krugman do not.

DeLong started off working for Summers and Krugman started off dismissing liberals' complaints about trade and NAFTA, as did DeLong. Bush's radicalism and nihilism pushed them both to the left.

Anyway I'm not clear on all of this but I don't think Dean Baker has mentioned monetary policy and the Triffin dilemma in regards to the trade deficit, except that monetary policy effects the exchange rate.

His story here from this morning makes sense to me. If I understand it correctly, the Triffin dilemma is where a reserve currency has to do monetary policy for the world and is posed with a dilemma, an example would can be seen in Europe which has a common currency but not a common banking union nor common fiscal policy.

Either have policy too tight in the center and appropriate for the periphery or it's appropriate for the center and too loose for the periphery. This is what happened in Europe which had appropriate policy for Germany during the 2000s after adoption of the Euro, but was too loose for the periphery. And now it is too tight for the periphery while appropirate for Germany.

I'm not sure how this fits with Rubin's strong dollar policy, but it did help our trading partners boost exports to the detriment of the U.S. export business. Clinton replaced this lost demand with demand from an asset bubble and Bush did the same with a housing bubble.

I think ultimately you can derive demand and full employment from some combination of trade/currency policy, fiscal and monetary policy. Each can be stimulative or not depending on the policies.

'In Praise of Econowonkery' by Mark Thoma

In the comment section, I did a link dump about the floor system safe asset paradigm shift genealogy.
