The 4% Non-Solution

by Kenneth Rogoff

Kenneth Rogoff is Professor of Economics and Public Policy at Harvard University, and was formerly chief economist at the IMF.

PARIS – For some time now, there has been concern that central bankers have “run out of bullets.” Having lowered their policy rates to near zero, they have engaged in increasingly extravagant measures such as “quantitative easing” and “forward guidance.” Given the fog cast over real economic activity by the financial crisis, it is difficult to offer a definitive assessment of just how well or badly those measures have worked. But it is clear that there must be a better way to do things.

There is no longer any reason to let the zero bound on nominal interest rates continue to hamper monetary policy. A simple and elegant solution is to phase in a switchover to a fully electronic currency, where paying interest, positive or negative, requires only the push of a button. And with paper money – particularly large-denomination notes – arguably doing more harm than good, currency modernization is long overdue. Using an electronic currency, central banks could continue to stabilize inflation exactly as they do now. (Citigroup’s chief economist, Willem Buiter, has suggested numerous ways to address the constraint of paper currency, but eliminating it is the easiest.)

A second, less elegant idea is to have central banks simply raise their target inflation rates from today’s norm of 2% to a higher but still moderate level of 4%. The idea of permanently raising inflation targets to 4% was first proposed in an interesting and insightful paper led by IMF chief economist Olivier Blanchard, and has been endorsed by a number of other academics, including, most recently, Paul Krugman. Unfortunately, the problem of making a smooth and convincing transition to the new target is perhaps insurmountable.

When Blanchard first proposed his idea, I was intrigued but skeptical. Mind you, two years previously, at the outset of the financial crisis, I suggested raising inflation to 4% or more for a period of a few years to deflate the debt overhang and accelerate wage adjustment. But there is a world of difference between temporarily raising inflation to address a crisis and unhinging long-term expectations.

After two decades of telling the public that 2% inflation is Nirvana, central bankers would baffle people were they to announce that they had changed their minds – and not in some minor way, but completely. Just recall the market’s “taper tantrums” in May 2013, when then-Fed Chairman Ben Bernanke suggested a far more modest turn in monetary policy. People might well ask why, if central bankers can change their long-term target from 2% to 4%, they could not later decide that it should be 5% or 6%?

Given the likelihood of a confused, mistrustful public, it is hard to find any deep rationale for a 4% target. At least the existing 2% inflation target stands for something, because central bankers can portray it as the moral equivalent of zero. (Most experts believe that a true welfare-based price index would show significantly lower inflation than government inflation statistics indicate, because official data fail to capture the benefits of the constant flow of new goods into the economy.)

There is an analogy to the problems countries faced when they tried to re-establish the gold standard after World War I. Until the war, money was backed by gold and could be redeemed at a fixed rate. Though the system was highly vulnerable to bank runs and there was little scope for a monetary stabilization policy, people’s confidence in the system enabled it to anchor expectations.

Unfortunately, the system completely collapsed after the war broke out in August 1914. Revenue-desperate combatants were forced to turn to inflation finance. They could not simultaneously debase the currency and back it with gold at a fixed rate.

After the war, as things settled down, governments tried to return to gold, partly as a symbol of a return to normalcy. But the revived inter-war gold standard ultimately fell apart, in no small part because it was impossible to rebuild public trust. A move by central banks to a long-term 4% inflation target risks triggering the same dynamic.

Fortunately, there is a much better way. Moving to an electronic government currency would not require a destabilizing change in the inflation target. Minor technical issues could easily be ironed out. For example, ordinary citizens could be allowed zero-interest-transactions balances (up to a limit). Presumably, nominal interest rates would move into negative territory only in response to a deep deflationary crisis.

But when such a crisis does occur, central banks could power out of it far more quickly than is possible today. And, as I have argued elsewhere, governments have long been penny-wise and pound-foolish to provide large-denomination notes, given that a large share are used in the underground economy and to finance illegal activities. Moving to a twenty-first-century currency system would make it far simpler to move to a twenty-first-century central-banking regime as well.

EXTRACTS: "Monetary policymakers are talking tough nowadays about fighting inflation to head off the risk of it spinning out of control. But that doesn’t mean they won’t eventually wimp out and allow the inflation rate to rise above target. Since hitting the target most likely requires a hard landing, they could end up raising rates and then getting cold feet once that scenario becomes more likely. Moreover, because there is so much private and public debt in the system (348% of GDP globally), interest-rate hikes could trigger a further sharp downturn in bond, stock, and credit markets, giving central banks yet another reason to backpedal." ----- "The historical evidence shows that a soft landing is highly improbable. That leaves either a hard landing and a return to lower inflation, or a stagflationary scenario. Either way, a recession in the next two years is likely."
May 26th 2022
EXTRACT: "No, I am not arguing that Powell needs to replicate Volcker’s tightening campaign. But if the Fed wishes to avoid a replay of the stagflation of the late 1970s and early 1980s, it needs to recognize the extraordinary gulf between Volcker’s 4.4% real interest rate and Powell’s -2.25%. It is delusional to believe that such a wildly accommodative policy trajectory can solve America’s worst inflation problem in a generation."
May 26th 2022
EXTRACT: "It will be critical in this context how China will act and whether it will prioritise its economic interests (continuing trade with Europe and the US) or current ideological preferences (an alliance with Russia that makes the world safe for autocracies)."
May 26th 2022
EXTRACT: "The document is full of embarrassing and damming stories of illegal gatherings and bad behaviour. There was “excessive alcohol consumption”, a regular fixture referred to as “wine time Fridays” and altercations between staff. Aides are shown to have left Downing Street after 4am (and not because they had worked into these early hours). Cleaning staff and junior aides were abused, and a Number 10 adviser is on record before the infamous “bring your own booze” party...."
May 17th 2022
EXTRACT: "But even a resounding Russian defeat is an ominous scenario. Yes, under such circumstances – and only such circumstances – Putin might be toppled in some kind of coup led by elements of Russia’s security apparatus. But the chances that this would produce a liberal democratic Russia that abandons Putin’s grand strategic designs are slim. More likely, Russia would be a rogue nuclear superpower ruled by military coup-makers with revanchist impulses. Germany after World War I comes to mind."
May 8th 2022
EXTRACT: "For citizens of states that are members of NATO, taking all possible steps, short of all-out war, to ensure that Russia does not conquer Ukraine is not even an altruistic sacrifice. It is a long-term investment, for themselves and their children, in freedom, democracy, and the international rule of law."
May 4th 2022
EXTRACT: ".....a remarkable transformation is taking place in Ukraine’s army amounting to its de facto military integration into Nato. As western equipment filters through to the frontline, Nato-standard weaponry and ammunition will be brought into Ukrainian service. This is of far higher quality than the mainly former Soviet weapons with which the Ukrainians have fought so capably. The longer this process continues and deepens, the worse the situation will be for the already inefficient Russian army and air force."
May 3rd 2022
EXTRACT: " The conventional wisdom among students of the Russian arts and sciences is that Russian culture is “great.” The problem is that, while there are surely great individuals within Russian culture, the culture as a whole cannot avoid responsibility for Putin and his regime’s crimes." ---- "Russianists will not be able to avoid examining themselves and their Russian cultural icons for harbingers of the present catastrophe. What does it mean that Fyodor Dostoevsky was a Russian chauvinist? That Nikolai Gogol and Anton Chekhov were Ukrainian? That Aleksandr Solzhenitsyn was an unvarnished imperialist? That Aleksandr Pushkin was a troubadour of Russian imperial greatness? May these writers still be read without one eye on the ongoing atrocities in Ukraine?"
Apr 29th 2022
EXTRACT: "The following day Lavrov met his Eritrean counterpart, Osman Saleh, in Moscow. Eritrea was the only African country to vote against the UN resolution condemning the invasion. In this refusal to condemn Russia, Eritrea was joined by only Belarus, North Korea and Syria. Even longstanding allies such as Cuba and China abstained. It’s an indication of Russia’s increasingly limited diplomatic options as this war continues."
Apr 24th 2022
EXTRACT: "Although the milestone lasted only for a brief time, it points to a future in which California runs on 100% wind, solar, hydro and batteries, a future that will certainly arrive even faster than the state plans. As it is, California is ahead of its green energy goals." ...... "A world of 100% green energy and electric cars is not only a healthier and more comfortable world, it is a world where oil and gas dictators like Vladimir Putin are defunded."
Apr 17th 2022
EXTRACT: "Kazakhstan’s authorities have also showed uncharacteristic leniency in allowing public rallies in support of Ukraine. Thousands of protesters holding banners reading “Russians, leave Ukraine”, “Long Live Ukraine” and “Bring Putin to trial” marched across the capital, Almaty, wrapping monuments to Lenin and other Soviet-era figures with yellow and blue balloons symbolising the Ukrainian flag."
Apr 15th 2022
EXTRACT: "People’s identification with the Soviet Union appears to have a clear and growing basis in Russian public opinion. Surveys we have conducted throughout the Putin period show that Soviet identification among the general population – something that had been steadily declining after the collapse of the Soviet Union in 1991 – began to increase in 2014, when the Russian government annexed Crimea and supported rebellions in the Ukrainian regions of Luhansk and Donetsk. By 2021, almost 50% of those surveyed identified with the Soviet Union rather than the Russian Federation."
Apr 13th 2022
EXTRACT: "Worse yet, the Hungarian government has effectively been helping Putin by prohibiting the shipment of weapons to Ukraine across its borders. Hungarian public TV spreads Russian disinformation day and night. The day before the election, an assembly of ordinary people expressing solidarity with Ukraine was framed on state television as a “pro-war rally.” "
Apr 13th 2022
EXTRACT: "It may well be that the Russian army’s fate has already been sealed in what is likely to be a long war. The single qualification to this may be that Russia could default to escalation using “weapons of mass destruction” of one form or another – whether tactical nuclear warheads or chemical weapons."
Apr 13th 2022
EXTRACTS" "Ukraine and Russia produce a substantial amount of grain and other food for export. Ukraine alone produces a whopping 6% of all food calories traded in the international market. At least it used to, before it was invaded by the world’s largest nuclear power." ...... "When it comes to cereals like wheat, corn, rice and barley, the big players talk about millions of metric tonnes, or MMTs. A single MMT of wheat contains about 3.4 trillion food calories,." ....."Ukraine produced about 80 MMT of grain (a category that includes wheat, corn and barley) in 2021, and is expected to harvest less than half of that this year. A shortfall of 40 MMT is enough missing calories that a country like the UK could only make it up by having everyone stop eating for three years. That’s the thing about tonnes of grain: a million here and a million there and pretty soon you’ve got a real issue on your plate."
Apr 11th 2022
EXTRACT: "I don’t even know the little girl’s name. All I do know is what a friend of a friend wrote on Viber: that her relative, a senior nurse in one of Kyiv’s hospitals, “saw in the morgue a child with 20 varieties of sperm on her small body.” Since this information was conveyed in a private conversation, there is no reason to doubt its veracity."
Apr 8th 2022
EXTRACT: "Russian society has so far failed to stop Putin, just as German society failed to stop Hitler. And so, like a poisoned chalice, that task has fallen to the West, as it did in 1939. The West must now treat Putin and his regime the same way that Winston Churchill treated Hitler: Don’t talk to him, just defeat him. Dead-enders such as Putin are too fanatical and desperate to be reliable negotiating partners."
Apr 3rd 2022
EXTRACT: "From 1807 to 1814 on the Iberian peninsula, Napoleon had to fight Spanish, Portuguese and British armies while beset by ubiquitous, ferocious insurgents. He described this war as his “bleeding ulcer”, draining him of men and equipment. It is the west’s aim to make Ukraine for Putin what Spain was for Napoleon. In the absence of a negotiated settlement, Ukraine and Nato will continue to grind away at Russia’s army, digging away at that bleeding ulcer and prolonging Russia’s agony on the military front, as the west continues its parallel assault on its economy. If Putin’s plan is to proceed with the Korea model, he will fail. There is a strong possibility that Putin has only a limited idea of how badly his army is faring. So be it – he’ll find out soon enough that there is now no path for him to military victory."

EXTRACTS: "Policymakers expected that the country would be able to secure its energy supply entirely from renewable sources, so they resolved to phase out coal and nuclear energy simultaneously. The last three of Germany’s 17 nuclear power plants are set to be shut down this year." ---- ".... the share of wind and solar power in Germany’s total final energy consumption, which includes heating, industrial processing, and traffic, was a meager 6.7%. And while wind and solar generated 29% of the country’s electricity output, electricity itself accounted for only about a fifth of its final energy consumption." ----- "If Germany suddenly halted Russian gas imports, gas-based residential heating systems – on which half the German population, approximately 40 million people, rely – and industrial processes that rely heavily on gas imports would break down....."
Apr 1st 2022
EXTRACT: "For Putin, the past that matters most is the one the dissident author and Nobel laureate Aleksandr Solzhenitsyn exalted: the time when the Slavic peoples were united within the Orthodox Christian kingdom of Kievan Rus’. Kyiv formed its heart, making Ukraine central to Putin’s pan-Slavic vision. ---- But, for Putin, the Ukraine war is about preserving Russia, not just expanding it. As Russian Foreign Minister Sergei Lavrov recently made clear, Russia’s leaders believe that their country is locked in a “life-and-death battle to exist on the world’s geopolitical map.” That worldview reflects Putin’s longstanding obsession with works of other Russian emigrant philosophers, such as Ivan Ilyin and Nikolai Berdyaev, who described a struggle for the Eurasian (Russian) soul against the Atlanticists (the West) who would destroy it. ---- Yet Putin and his neo-Eurasianists seem to believe that the key to victory is to create the kind of regime those anti-Bolshevik philosophers most detested: one run by the security forces. A police state would fulfill the vision of another of Putin’s heroes: the KGB chief turned Soviet General Secretary Yuri Andropov."
