The COVID-19 crisis is mere foreboding of a more serious, existential crisis to come. At the same time, this could still be avoided if we sought an alternative mindset that values the preservation of life and the extension of knowledge. Within this larger approach to life as we know it, concrete economic proposals can start us in the right direction, including the «Modern Debt Jubilee» proposed here.
The world is drowning in debt, and the situation is only getting worse, especially in the wake of the COVID-19 pandemic. All types of debt—government, household and corporate—have been rising, relative to GDP, in almost all countries. Debt in the USA is the highest it has ever been. Debt levels for some selected economies shows a representative sample of major economies since World War II. Australia is the worst on household debt, France on corporate debt, and Japan on both government and total debt. Almost all countries have experienced rising total debt since World War II.  There are only a handful of exceptions, like Germany, where public and private debt have been driven mainly by large current account surpluses that have enabled those economies to grow despite little debt growth from either the private or government sectors.
All schools of economic thought hold that a high level of debt is a problem—they just differ on what sort of debt they worry about. Neoclassical (and «Austrian») economists worry about government debt. They claim that government debt «crowds out» private sector investment, by borrowing money that the private sector could have used to invest, and that it saddles future generations with the burden of paying back that debt  Mankiw, N.G. (2016). Macroeconomics (9th edition). ed. Macmillan.. They do not worry about private debt, because they see changes in the level of private as simply a transfer of spending power from one private individual to another, and they claim that, unless there are huge differences in their tendency to spend money, the effect on the macro economy should be slight  Bernanke, B.S. (2000). Essays on the Great Depression. Princeton University Press..
Post-Keynesian (and «MMT») economists worry about private debt. They claim that bank lending creates money, and this adds to demand, directly affecting the macro economy. Financial crises are caused by too high a level of private debt, followed by credit—the change in debt—turning negative  Keen, S. (2020). Emergent Macroeconomics: Deriving Minsky’s Financial Instability Hypothesis Directly from Macroeconomic Definitions. Review of Political Economy 32 (3), 342-370. doi:10.1080/09538259.2020.1810887. They do not worry about government debt, because they point out that the government «owns its own bank», and can create the money needed to pay interest on its debt, so long as it is denominated in its own currency  Kelton, S. (2020). The Deficit Myth: Modern Monetary Theory and the Birth of the People’s Economy. Public Affairs..
In 2014, The Bank of England came down on the side of the Post Keynesians in this dispute: contrary to what economic textbooks argue, bank lending creates money. This new money is borrowed in order to be spent, so that new private debt adds to aggregate demand, driving both GDP and asset prices. The primary explanation for the savage decline in the Spanish economy from 2008 to 2014 was the plunge in credit—the change in private debt—from plus 35% of GDP in 2008 to minus 20% in 2014.

The boom, bust and recovery of American house prices between 1997 and now was driven by changes in the level of household credit. Though the underlying factor in the stock market boom since 2009 has been quantitative easing, changes in margin debt have driven the ups and downs of the market. Our «post-Global-Financial-Crisis» world is thus characterized by excessive private sector debt and a moribund private sector, with economic performance kept afloat predominantly by government schemes (like quantitative easing) and large budget deficits that in turn lead to high levels of government debt. To escape from this impasse, we need to reduce private debt relative to GDP—and preferably without also further increasing the government debt to GDP ratio.
Conventional ideas about how to reduce the level of debt compared to GDP boil down to three solutions: to simply pay the debt down, to grow GDP faster than debt, or to «inflate our way out of debt.» However, the empirical record implies that none of these methods will work. Irving Fisher, who developed the «Debt-Deflation Theory of Great Depressions» pointed out that the «pay it down» route fails because reducing debt directly also destroys money dollar for dollar: just as a new loan increases the money supply, paying debt down reduces it. The fall in money can cause a greater fall in GDP, thus resulting in a rising debt to GDP ratio from direct repayment of debt—a phenomenon that I call «Fisher’s Paradox.»  Fisher, I. (1932). Booms and Depressions: Some First Principles. Adelphi.  Fisher, I. (1933). The Debt-Deflation Theory of Great Depressions, Econometrica 1 (4),337-357
A higher level of private debt, even with falling interest rates, results in a larger fraction of the economy’s money residing in the financial sector rather than the real economy—the shops and factories where physical output are produced, and profits and wages are actually generated.
A «Modern Debt Jubilee» could achieve this. A Modern Debt Jubilee uses the capacity of the government to create money to reduce private debt by effectively swapping credit-backed money for fiat-backed money:
·Rather than debtors having their debt reduced, everyone—borrower or saver—is given the same amount of government-created money;
·Debtors must reduce their debt; savers get cash that must be used to buy newly-issued corporate shares;
·The proceeds from selling these shares must be used to pay down corporate debt; and
·The Jubilee gives banks the finances needed to buy «Jubilee Bonds,» the interest income from which compensates them for the fall in their income from private debt.
The ideas below reflect a simulation that models a Modern Debt Jubilee using Minsky  https://sourceforge.net/projects/minsky/, an Open Source (i.e., free) system dynamics program. Minsky’s unique feature, called a «Godley Table,» is a double-entry bookkeeping table that makes it much easier to model financial dynamics than it is in standard system dynamics programs. The key outcomes of the model are:
·The Jubilee reduces overall debt levels, relative to GDP;
·The private debt to GDP ratio falls immediately because of the Jubilee;
·Government debt rises as much as private debt falls, but the government debt to GDP ratio rises less because of the stimulatory effects of the Jubilee on GDP;
·The total debt to GDP ratio therefore falls immediately as a result of the Jubilee; and
·Over time, the Jubilee stimulates the economy because the fall in indebtedness boosts aggregate demand, by transferring money from those who spend slowly (primarily bankers) to those who spend quickly (workers).
A policy which requires an initial increase in government debt—as fiat-created money replaces credit-based money—thus ends up reducing both government and private debt relative to GDP, as demonstrated in Figure 1.
How does this magic happen? The basic mechanism is that the Modern Debt Jubilee reduces the inequality that the rising level of private debt has caused.
A higher level of private debt, even with falling interest rates, results in a larger fraction of the economy’s money residing in the financial sector rather than the real economy—the shops and factories where physical output are produced, and profits and wages are actually generated. The Modern Debt Jubilee reverses this: by reducing private debt levels, less debt-servicing is needed, and therefore more of the existing amount of money turns up in the hands of workers, who spend much more rapidly than do bankers. Because they spend more rapidly, that money expands activity in the firm sector, causing GDP to rise. The increase in what mainstream economists call the «velocity of money» (see Figure 2) generates more GDP from the same amount of money, and debt to GDP ratios fall over time. A Modern Debt Jubilee thus reverses Fisher’s Paradox.
The increase in Reserves enables the next step: the sale of Jubilee Bonds by Treasury to the private banks. The Jubilee has increased the Reserves of the banking sector; the sale of Jubilee Bonds allows the banks to swap this non-income-earning, non-tradeable asset for Jubilee Bonds, which can be traded and can earn interest, just like standard Government Bonds. This is the key truth to «Modern Monetary Theory»: because the government is a money creator, government spending is self-financing. Financing, in other words, is not the problem: problems, if any, lie with the consequences of that spending, rather than its financing.
Here we have not spending, but a «gift» to the private, non-bank public: the government gives the public money which must be used to pay down private debt. Of course, the banking sector will accept this gift—which is why every government bond issue in history has been oversubscribed. There are no «Bond Vigilantes,» only «Bond Idiots,» who would turn down not one gift but two.
How much this second gift costs—in terms of the interest payments made on the bonds—depends on how much of the bond issue remains with private banks. It is quite possible for the Central Bank to buy all of the Jubilee Bonds from the private banks if it wishes: all it has to do is credit their Reserve balances (the Central Bank’s Liability to private banks) and put the bonds on its balance sheet as an Asset of equivalent value. This would then mean that the Jubilee would cost the government nothing, because it would be financed by one part of the Government (the Treasury) going into debt with another part (the Central Bank).
But the biggest objectors to that happening would probably be the private banks themselves, because the reduction in private debt—by roughly 100% of GDP in the simulations here—would reduce their income dramatically. Then, the Treasury paying interest on the bonds to the banks is the «cost» of the Jubilee: it’s the amount of interest needed to keep the banking sector happy, after it loses a large source of income from the repayment of private debt. It is quite possible for interest rate on Jubilee Bonds to be set at a level which fully compensates the banking sector for the loss of income from interest on private debt.
The interest itself can be raised by Treasury borrowing from the Central Bank—so if the Jubilee were of the order of 100% of GDP, as in these simulations, the annual «cost» of this would be an increase in the Treasury’s debt to the Central Bank of 5% of GDP, or $1 trillion per year in the USA. There is also a social bonus to paying interest on the Jubilee Bonds: as well as compensating the banks for lost income on private debt, it also creates money: it increases the Reserves (Assets) of the banking sector and its Equity at the same time.  This simple model treats bank equity as «at call,» like deposit accounts; a more sophisticated model would have bank interest income going into an at call account while Equity was long-term. The same overall result would still apply.
So the «cost» of the Jubilee would be a $1 trillion injection of new money into the banking sector every year.
A Modern Debt Jubilee would thus overcome the problem of an excessive ratio of debt to GDP by affecting the denominator—GDP—more than the numerator—debt, both public and private. Its main effects occur because of its effects on the money supply—both who has it, and how it grows. This reallocation of existing money reverses the historic mistake Central Banks have made via quantitative easing, which was undertaken ostensibly to stimulate the economy, and did by making the wealthy wealthier, via higher share prices.
We cannot continue operating on the assumption that the financial system is
More policies would be needed to support a Jubilee: you wouldn’t want to reduce the private debt burden, and then have banks recreate it via the irresponsible lending practices they have followed in the last 40 years. This would include curbs on bank lending for asset purchases, and encouragement to banks to lend to firms and entrepreneurs, rather than to speculators.
Government policy after the Jubilee should be expanded from targeting only unemployment and inflation to include targeting private debt as well. It needs to be kept at sustainable levels—of the order of the 50% of GDP that it was in capitalism’s Golden Age after World War II. It is possible to see this last time we escaped from a private debt trap—the 1930s and 1940s—as a crude version of what I am proposing here. Increased government spending, firstly for the New Deal and then for World War II, enabled the private sector to drastically reduce its debt level.
We just need to avoid the mistakes made back then, of reducing private sector debt by a war rather than a «Jubilee,» and of allowing the private banking genie to get out of the bottle again afterwards. A well-functioning economy needs a balance of fiat and credit money, and once this is restored by a Modern Debt Jubilee, it needs to be maintained by a government that is well aware of the dangers of surrendering control over the money supply to those whom Marx so aptly characterized as the Roving Cavaliers of Credit  Marx, K. (1894). Capital. (Vol. #3). International Publishers. Available on https://www.marxists.org/archive/marx/works/1894-c3/ch33.htm. These actors «can afford to pay a high interest because they pay it out of other people’s pockets,» setting high interest rates for everyone else while living «in grand style on anticipated profits.»
While precisely these «cavaliers» decry debt, they still cling to unquestioned conventional wisdom that bears the worst consequences for those who can least afford it. We cannot continue operating on the assumption that the financial system is self-regulating. Ultimately, following Robert Shiller, economics is more about telling stories than explaining capitalism. Public policy must then draw on authentic knowledge and innovation to reorient society towards the collective benefit, even if it means admitting the beliefs that brought us to this point were mistaken. Such belief systems are the hallmark of being human, but here is where education and the scientific method comes into play: an educated society is a barrier against collectively stupid decisions, and it is time to reverse these decisions before their consequences become irreversible.
