Watching as the Federal Reserve juggles priceless eggs in variable gravity…

Is it necessary to say that we hold Ben Bernanke, Mervyn King, Mark Carney, Janet Yellen, Stan Fischer, Lael Brainard, and company to the highest of high standards–demand from them constant triple aerial somersaults on the trapeze–because we have the greatest respect for and confidence in them? It probably is…

Back in 1992 Larry Summers and I wrote that pushing the target inflation rate from 5% down to 2% was a very dubious and hazardous enterprise because the zero-lower bound was potentially a big deal: “The relaxation of monetary policy seen over the past three years in the United States would have been arithmetically impossible had inflation and nominal interest rates both been three percentage points lower in 1989. Thus a more vigorous policy of reducing inflation to zero in the mid-1980s might have led to a recent recession much more severe than we have in fact seen…”

This does seem, in retrospect, to have been quite possibly the smartest and most foresightful thing I have ever written. Future historians will, I think, have a very difficult time explaining how the cult of 2%/year inflation targeting got itself established in the 1990s. And they will, I think, have an even harder time explaining why the first monetary policymaker reaction to 2008-2012 was not to endorse Olivier Blanchard et al.’s call for a higher, 4%/year, inflation target in the coded terms of IMF speak:

The great moderation (Gali and Gambetti 2009) lulled macroeconomists and policymakers alike in the belief that we knew how to conduct macroeconomic policy. The crisis clearly forces us to question that assessment….

The crisis has shown that large adverse shocks do happen. Should policymakers aim for a higher target inflation rate in normal times, in order to increase the room for monetary policy to react to such shocks? Are the net costs of inflation much higher at, say, 4% than at 2%, the current target range? Is it more difficult to anchor expectations at 4% than at 2%? Achieving low inflation through central bank independence has been a historic accomplishment. Thus, answering these questions implies carefully revisiting the benefits and costs of inflation.

A related question is whether, when the inflation rate becomes very low, policymakers should err on the side of a more lax monetary policy, so as to minimize the likelihood of deflation, even if this means incurring the risk of higher inflation in the event of an unexpectedly strong pickup in demand. This issue, which was on the mind of the Fed in the early 2000s, is one we must return to…

But instead we got a very different reaction. Sudeep Reddy reported on it back in 2009:

Sudeep Reddy (2009): Sen. Vitter Presents End-of-Term Exam For Bernanke: “Earlier this month, Real Time Economics presented questions from several economists…

…for the confirmation hearing of Federal Reserve Chairman Ben Bernanke…. Sen. David Vitter (R., La.) submitted them in writing and received the responses from Bernanke….

D. Brad Delong, University of California at Berkeley and blogger: Why haven’t you adopted a 3% per year inflation target?

[Bernanke:] The public’s understanding of the Federal Reserve’s commitment to price stability helps to anchor inflation expectations and enhances the effectiveness of monetary policy, thereby contributing to stability in both prices and economic activity. Indeed, the longer-run inflation expectations of households and businesses have remained very stable over recent years. The Federal Reserve has not followed the suggestion of some that it pursue a monetary policy strategy aimed at pushing up longer-run inflation expectations.

In theory, such an approach could reduce real interest rates and so stimulate spending and output. However, that theoretical argument ignores the risk that such a policy could cause the public to lose confidence in the central bank’s willingness to resist further upward shifts in inflation, and so undermine the effectiveness of monetary policy going forward.

The anchoring of inflation expectations is a hard-won success that has been achieved over the course of three decades, and this stability cannot be taken for granted. Therefore, the Federal Reserve’s policy actions as well as its communications have been aimed at keeping inflation expectations firmly anchored.

This sounds like nothing so much as the explanations offered in the 1920s and 1930s for returning to and sticking with the gold standard at pre-WWI parities, and the explanations offered at the start of the 1990s by British Tories for sticking to the fixed parities of the then-Exchange Rate Mechanism. The short answer is that real useful positive credibility is not built by attempts to stick to policies that are in the long run destructive–and hence both incredible and stupid. As we learn more about the economy and as the structure of the economy changes, the optimal long-run policy strategy changes as well. Credibility arising from a commitment that the Federal Reserve will seek to follow an optimal long-run policy framework and to accurately convey its intentions but will revise that framework in light of knowledge and events is worth gaining and maintaining. Credibility arising from a commitment to stick, come hell or high water, to a number that Alan Greenspan essentially pulled out of the air with next to no substantive analytical backing in terms of optimal-control analysis is not.

Now, however, we have another answer from Janet Yellen: that the zero lower bound is not, in fact, such a big deal:

Janet Yellen: The Outlook, Uncertainty, and Monetary Policy: “One must be careful, however, not to overstate the asymmetries affecting monetary policy at the moment…

…Even if the federal funds rate were to return to near zero, the FOMC would still have considerable scope to provide additional accommodation. In particular, we could use the approaches that we and other central banks successfully employed in the wake of the financial crisis to put additional downward pressure on long-term interest rates and so support the economy–specifically, forward guidance about the future path of the federal funds rate and increases in the size or duration of our holdings of long-term securities.10 While these tools may entail some risks and costs that do not apply to the federal funds rate, we used them effectively to strengthen the recovery from the Great Recession, and we would do so again if needed.

Over on the Twitter Machine, the very-sharp Tim Duy–I take it from his picture that there is ample snowpack for the ski resorts in the Cascade Range–is impressed by how different the tone of this speech is with the get-ready-for-liftoff speeches of last fall:

And Dario Perkins and Mark Grady have chimed in in support: “suddenly she’s realised the rest of the world matters!…” and “lots of common messages, but emphasis v[ery] diff[erent] on the risks. And no mention of lags or falling behind the curve at all…”

I, by contrast, am still struck by the gap that remains between where she seems to be and where I am.

For there is a natural next set of questions to ask anyone who says that the zero lower bound and the liquidity trap are not big deals. That set is:

  • Then why isn’t nominal GDP on its pre-2008 trend growth path?

  • Why is the five-year ahead five-year market inflation outlook so pessimistic?

  • Why hasn’t the Federal Reserve pushed interest rates low enough so that investment as a whole counterbalances the collapse in government purchases we have seen since 2010?

I cannot help but be struck by the difference between what I see as the attitude of the current Federal Reserve, anxious not to do anything to endanger its “credibility”, and the Greenspan Fed of the late 1990s, which assumed that it had credibility and that because it had credibility it was free to experiment with policies that seemed likely to be optimal in the moment precisely because markets understood its long-term objective function and trusted it, and hence would not take short-run policy moves as indicative of long-run policy instability. There is a sense in which credibility is like a gold reserve: It is there to be drawn on and used in emergencies. The gold standard collapsed into the Great Depression in the 1930s in large part because both the Bank of France and the Federal Reserve believed that their gold reserves should never decline, but always either stay stable of increase.

It was Mark Twain who said that although history does not repeat itself, it does rhyme. The extent to which this is true was brought home to me recently by Barry Eichengreen’s excellent Hall of Mirrors

Must-read: Martin Wolf: “Helicopter drops might not be far away”

Must-Read: The central banks of the North Atlantic seem to be rapidly digging themselves into a hole in which, if there is an adverse demand shock, their only options will be (a) dither, and (b) seize the power to do a degree of fiscal policy via helicopter money by some expedient or other…

Martin Wolf: Helicopter drops might not be far away: “The world economy is slowing, both structurally and cyclically…

…How might policy respond? With desperate improvisations, no doubt. Negative interest rates… fiscal expansion. Indeed, this is what the OECD, long an enthusiast for fiscal austerity, recommends…. With fiscal expansion might go direct monetary support, including the most radical policy of all: the ‘helicopter drops’ of money recommended by the late Milton Friedman… the policy foreseen by Ray Dalio, founder of Bridgewater, a hedge fund….

Why might the world be driven to such expedients? The short answer is that the global economy is slowing durably…. Behind this is a simple reality: the global savings glut — the tendency for desired savings to rise more than desired investment — is growing and so the ‘chronic demand deficiency syndrome’ is worsening…. The long-term real interest rate on safe securities has been declining for at least two decades….

It is this background — slowing growth of supply, rising imbalances between desired savings and investment, the end of unsustainable credit booms and, not least, a legacy of huge debt overhangs and weakened financial systems — that explains the current predicament. It explains, too, why economies that cannot generate adequate demand at home are compelled towards beggar-my-neighbour, export-led growth via weakening exchange rates….

The OECD argues, persuasively, that co-ordinated expansion of public investment, combined with appropriate structural reforms, could expand output and even lower the ratio of public debt to gross domestic product. This is particularly plausible nowadays, because the major governments are able to borrow at zero or even negative real interest rates, long term. The austerity obsession, even when borrowing costs are so low, is lunatic (see chart). If the fiscal authorities are unwilling to behave so sensibly — and the signs, alas, are that they are not — central banks are the only players… send money… to every adult citizen. Would this add to demand? Absolutely….

The easy way to contain any long-term monetary effects would be to raise reserve requirements. These could then become a desirable feature of our unstable banking systems…. The economic forces that have brought the world economy to zero real interest rates and, increasingly, negative central bank rates are, if anything, now strengthening…. Policymakers must prepare for a new ‘new normal’ in which policy becomes more uncomfortable, more unconventional, or both…

A world off-balance on monetary policy

Nouriel Roubini writes:

Nouriel Roubini: “Worries about a hard landing in China… China is more likely to have a bumpy landing than a hard one…

…[but] investors’ concerns have yet to be laid to rest…. Emerging markets are in serious trouble…. The Fed probably erred in exiting its zero-interest-rate policy in December…

And it is not clear how the Federal Reserve can correct what is now widely-recognized as a probable error.

First, the Federal Reserve would have to be willing to admit that the asymmetric loss function meant that exiting zero last December was a probable error.

It was a probable error in retrospect today, and was unwise in prospect last December. Right now we are worried about global deflation. It is difficult to envision an alternative counterfactual scenario today in which we are equally worried about global inflation and equally regret that the Federal Reserve did not exist zero last December. When there is a substantial loss associate with a Type A error and only a minor loss associated with a Type B error, one risks making the Type B error unless the odds are overwhelming. The odds last December were to overwhelming.

The problem for the Federal Reserve is that admitting it made a policy error last December requires an all-but-explicit climbdown from the last two years’ worth of public risk judgments, and an explanation of why, given the obvious asymmetries, those public risk judgments were explained. And there is no face-saving way to undertake such a climbdown.

Second, the Federal Reserve would have to take steps to neutralize the contractionary pressure its policy move in December and the previous telegraphing of that move have put on the world economy. And that would be a difficult task indeed.

It looks like Ben Bernanke is about to go through the options. And that will definitely be worth reading.

The most recent data provide much more reason for concern that the economy is slowing more than inflation is accelerating….

There are many other measures indicating that there continues to be considerable slack in the labor market despite the relatively low unemployment. There are no plausible explanations for the sharp drop in the employment rate of prime-age workers at all education levels from pre-recession levels, apart from the weakness of the labor market. The amount of involuntary part-time employment continues to be unusually high…. And the duration measures of unemployment spells and the share of unemployment due to voluntary quits are both much closer to recession levels than business cycle peaks…

Yellen is caught in a tug of war between Fischer and Brainard. At stake is the Fed chair’s willingness to embrace a policy stance that accepts the risk that inflation will overshoot the U.S. central bank’s target. At the moment, Brainard has the upper hand in this battle. And she has a new weapon on her side: increasing concerns about the stability of inflation expectations….

Fischer’s not alone. In his group sit Federal Reserve Bank of San Francisco President John Williams, Kansas City Fed President Esther George, and Cleveland Fed President Loretta Mester.

Must-Read: FastFT: Draghi Day: “Rabobank describes the wild market moves that followed the European Central Bank rates decision and press conference as ‘carnage’…

…Whether that’s the ECB’s fault or the markets’ depends on who you speak to. Here’s a taste…. Jim Reid at Deutsche Bank sees signs of a strop in the market…. “Imagine you were expecting a trip during school holidays in a caravan around the country but instead you can take 2 weeks off school, fly first class to Disneyworld, have a go in the cockpit on the way, stay at a hotel made of chocolate, and then be able to go on every ride every day without queuing and have a private play session with the real Mickey Mouse as each day draws to a close. However if the market was the same kid its reaction yesterday was ‘do I not get unlimited spending money, and where are we going for our summer holidays then?’”…

Frederik Ducrozet at Pictet says ‘don’t fight the ECB’: “Such a policy package designed to boost bank lending and to improve QE implementation should lead to a significant easing of monetary and financial conditions. We are positive on the net impact….” Peter Schaffrik at RBC: “We do not share the negativity and could well imagine that the initiative to engage in risky assets will find more coverage going forward.”… And the economics team at BNP Paribas….

Now for the critics…. Lutz Karpowitz from Commerzbank says the central bank is ‘firing blanks’. He has issues with TLTRO 2, where the banks can effectively fund their lending at negative rates from the ECB…. Grant Lewis from Daiwa…. “The cost of finance is only one consideration for banks when deciding whether to lend or not – of at least equal importance is how the underlying economy, and hence the loan itself, is expected to perform. And on that measure it’s far from certain that today’s announcements will prove transformative to the economic outlook. Indeed, the ECB’s own forecast for 2017 sees growth of just 1.7% and inflation well below target at just 1.3%.” Rabobank’s Piotr Matys says ECB can forget about talking the euro down: “The damage to bearish bets against the euro, however, has been done. Those market participants, including yours truly, who went into the ECB meeting with a bearish view on the euro ended Thursday’s session calculating their losses instead of celebrating profits… after such a massive blow as on Thursday Draghi and other ECB officials may find it even more difficult, if they choose to do so, to talk the euro down.”

Citi‘s rates team says Draghi’s bazooka has ‘backfired’: “The bazooka backfired because the ECB is taking rate cuts off the table. We expect easing to be priced out. The measures do little to convince us that realised inflation will move higher any time soon.” That said, the same bank’s emerging-markets team says ‘the ECB delivered’: “There is now an incentive to move away from a policy fully centered on negative rates, to a toolset centered on further relief of financing in the banking sector. The markets should be cheering that, rather than reacting in a negative way.”

Social credit is the answer

Why is it called: “helicopter money”? Why isn’t it called: “expansionary fiscal policy with monetary support to neutralize any potential crowding-out of private-sector spending”?

Why did Milton Friedman set it forth in his writings as one of the paradigmatic cases of expansionary monetary policy? Why did Ben Bernanke refer to it and so gain his unwanted nickname of “Helicopter Ben”?

In Milton Friedman’s case, I believe that it was a conviction that the LM curve was steep enough and the IS curve flat enough that the fiscal side was fundamentally unimportant–that about the same effects were achieved whether the extra money was introduced into the economy via being dropped from helicopters or via open-market operations. To focus on how open-market operations worked would thus confuse listeners who would then have to think through asset market-equilibrium to no substantive gain in understanding. In Friedman’s view, the entire Tobin analytical tradition, not to mention Wicksell, was largely a distracting waste of time. So why go there?

In the case of Ben Bernanke and of the rest of the participants in today’s debate, I think it is has different causes. I think it is a result of the default Washington-Consensus Great-Moderation assignment of the stabilization-policy role to independent and technocratic central banks. In that paradigm, directly-elected governments are supposed to limit their focus to the “classical” tasks of rightsizing the public sector and adopting an appropriately-prudent long-term government-spending financing plan.

To speak of “expansionary fiscal policy with monetary support to neutralize any potential crowding-out of private-sector spending” is to open a can of worms. To speak of “helicopter money” is to convey the impression that this is the central bank undertaking its proper business, but in a context in which as a result of unfortunate historical accidents of institutional development the independent central bank needs the active support of the directly-elected government. The active support of the directly-elected government is needed undertake what is, after all, a fundamentally monetary policy. And it is, in this line of thinking, a fundamentally monetary policy: Milton Friedman himself said so.

Now comes the extremely-sharp Adair Turner to try to focus the debate in a productive direction.

Many today are unwilling to advocate for more expansionary fiscal policy out of:

  1. a fear that many economies that would find their governments engaging in it lack fiscal space for it to be of much use,
  2. a fear that directly-elected governments allowed to cross the line and engage in open-ended explicitly stabilization policy will not give due weight to the objective of keeping inflation low over the long term, or
  3. a fear that central banks allowed to control fiscal-policy levers will be captured by and use their powers to then take taxpayers’ money and spend it enriching the banking sector.

So what is the solution? How can we build institutions that will:

  1. avoid the Scylla of allowing directly-elected governments that use fiscal levers in support of monetary expansion to enforce fiscal dominance and abandon prudent inflation targets, while also

  2. avoiding the Charybdis of allowing central banks that may well have been partially-captured by their banking sectors of using their powers to spend the taxpayers’ money further enriching the bankers?

The solution is obvious: Social Credit. Adopt the policies of the Social Credit Part of Alberta in the 1930s. Adopt the policies of Upton Sinclair’s campaign for Governor of California in the 1930s. Adopt the policies that are taken as a matter of course and are in the background of Robert A. Heinlein’s 1947 novel Beyond This Horizon.

Central banks should, instead of taking all the revenue from seigniorage they create and transferring it all back to the Treasury, calculate each quarter how much of the seigniorage they hold should be distributed to citizens in the form of that quarter’s helicopter drop.

I am not certain about how the legal-institutional constraints bind the BoJ, and ECB, and the BoE. I believe that the Federal Reserve could start such a policy régime today:

  1. Incorporate–for free–everybody with a Social Security number as a bank holding company.
  2. Let everybody then have their personal bank holding company join–again for free–the Federal Reserve system as a member bank.
  3. Offer every such personal bank holding company a permanent long-term open-ended infinite-duration zero-interest line-of-credit to draw on, up to some set maximum nominal amount.
  4. Raise the amount of the line-of-credit maximum every quarter by that quarter’s desired helicopter drop.

The same institutional forces that have, since the selection Paul Volcker, kept the Federal Reserve focused on avoiding an inflationary spiral would still bind. There would be no way to gimmick such a Social Credit system to turn it into a giveaway to the bankers. It would give the Federal Reserve the power to engage in the one policy that nearly all economists are confident will always have traction on nominal demand. Once the Federal Reserve was off and rolling, other central banks would, I think, quickly find mechanisms within their current institutional-legal competence to accomplish the same ends.

And it would, I think, make the FOMC and its members “very popular”, as Marty Feldman playing Igor in the movie Young Frankensteinsays of the monster they are creating.

Adair Turner: Are Central Banks Really Out of Ammunition?: “The global economy faces a chronic problem of deficient nominal demand…

…But the debate about which policies could boost demand remains inadequate, evasive, and confused. In Shanghai, the G-20 foreign ministers committed to use all available tools – structural, monetary, and fiscal – to boost growth rates and prevent deflation. But many of the key players are keener to point out what they can’t do than what they can….

Central banks frequently stress the limits of their powers, and bemoan lack of government progress toward ‘structural reform’…. But while some [SR measures] might increase potential growth over the long term, almost none can make any difference in growth or inflation rates over the next 1-3 years…. Vague references to ‘structural reform’ should ideally be banned, with everyone forced to specify which particular reforms they are talking about and the timetable for any benefits that are achieved…. Central bankers are right to stress the limits of what monetary policy alone can achieve…. Negative interest rates, and… yet more quantitative easing… can make little difference to real economic consumption and investment. Negative interest rates… [may have the] the actual and perverse consequence… [of] higher lending rates….

Nominal demand will rise only if governments deploy fiscal policy to reduce taxes or increase public expenditure – thereby, in Milton Friedman’s phrase, putting new demand directly ‘into the income stream.’ But the world is full of governments that feel unable to do this. Japan’s finance ministry is convinced that it must reduce its large fiscal deficit…. Eurozone rules mean that many member countries are committed to reducing their deficits. British Chancellor of the Exchequer George Osborne is also determined to reduce, not increase, his country’s deficit. The standard official mantra has therefore become that countries that still have ‘fiscal space’ should use it. But there are no grounds for believing the most obvious candidates – such as Germany – will actually do anything….

These impasses have fueled growing fear that we are ‘out of ammunition’…. But if our problem is inadequate nominal demand, there is one policy that will always work. If governments run larger fiscal deficits and finance this not with interest-bearing debt but with central-bank money…. The option of so-called ‘helicopter money’ is therefore increasingly discussed. But the debate about it is riddled with confusions.

It is often claimed that monetizing fiscal deficits would commit central banks to keeping interest rates low forever, an approach that is bound to produce excessive inflation. It is simultaneously argued (sometimes even by the same people) that monetary financing would not stimulate demand because people will fear a future ‘inflation tax.’
Both assertions cannot be true; in reality, neither is. Very small money-financed deficits would produce only a minimal impact on nominal demand: very large ones would produce harmfully high inflation. Somewhere in the middle there is an optimal policy…. The one really important political issue is ignored: whether we can design rules and allocate institutional responsibilities to ensure that monetary financing is used only in an appropriately moderate and disciplined fashion, or whether the temptation to use it to excess will prove irresistible. If political irresponsibility is inevitable, we really are out of ammunition that we can use without blowing ourselves up. But if, as I believe, the discipline problem can be solved, we need to start formulating the right rules and distribution of responsibilities…

Note also that chapter 23, “Notes on Mercantilism, the Usury Laws, Stamped Money and Theories of Under-Consumption”, of John Maynard Keynes’s General Theory of Employment, Interest and Money can be read with great profit here…
