An MMT response to Jared Bernstein – Part 1

There was an article posted by American political analyst Jared Berstein yesterday (January 7, 2018) – Questions for the MMTers – which I thought was a very civilised exercise in engagement from someone who is clearly representative of the more standard Democratic Party view, that the US government has to move towards balancing its fiscal position and reducing government debt in order to meet the social security challenges posed by an ageing population and the accompanying increase in dependency ratios. He is sympathetic to Modern Monetary Theory (MMT), given that he wrote “there’s no distance between my views and a core principal of MMT: the need for deficit spending when the economy is below full employment”.

There was an article posted by American political analyst Jared Berstein yesterday (January 7, 2018) – Questions for the MMTers – which I thought was a very civilised exercise in engagement from someone who is clearly representative of the more standard Democratic Party view, that the US government has to move towards balancing its fiscal position and reducing government debt in order to meet the social security challenges posed by an ageing population and the accompanying increase in dependency ratios. He is sympathetic to Modern Monetary Theory (MMT), given that he wrote “there’s no distance between my views and a core principal of MMT: the need for deficit spending when the economy is below full employment”. In other words, he notes that “MMT or whomever else argues on behalf of expansionary fiscal policy is correct”. But that is a fairly standard ‘progressive’ position when the economic cycle is below full capacity. This position typically alters quite dramatically when so-called longer terms considerations are brought into the picture. Jared Bernstein worries about the inflationary consequences of fiscal policy (so do MMT economists by the way) and thinks central banks should be the primary macroeconomic policy makers (MMT economists reject this). He also thinks that if the government doesn’t sell bonds to match its deficits then there will be “currency debasing”. MMT economists have pointed out the fallacies of that proposition but he is still in the dark about it. And he also things that fiscal position should be balanced at full employment. MMT economists do not agree with that proposition pointing out that it all depends on the state of saving and spending decisions in the non-government sector. It is likely that continuous deficits will be required even at full employment given the leakages from the income-spending cycle in the non-government sector. So while his queries are conciliatory and written in an inquiring fashion, the gulf between this typical ‘progressive’ view of macroeconomics and MMT is rather wide. This is Part 1 of a two-part series that responds to the questions that Jared Bernstein raises and hopefully puts the record a bit straighter.

Jared Bernstein was close to the Obama Administration and has clearly articulated a ‘progressive’ viewpoint within the strange milieu that is American politics.

It is also getting more strange by the week – from the outside anyway.

He currently is associated with the Center on Budget and Policy Priorities, which is a US ‘think tank’ that says it researches “federal and state policies designed both to reduce poverty and inequality and to restore fiscal responsibility in equitable and effective ways”.

Their list of policy priorities conforms squarely with my own values – health, low-income assistance – food, housing, climate change, pension systems.

But the devil is in the detail and I think they over obsess about whether the US government can afford these progressive programs.

Their analysis of the Trump tax cut disaster has focused on the effects on the deficit using statements such as “adding nearly $1.5 trillion to deficits over ten years” to scare people into abandoning political support for the Republicans.

This analysis, has, in turn, been used by Democratic Party politicians and economists supporting them to relentlessly attack the tax cuts on the basis of their implications for the deficit.

For example, Lawrence Summers – he of the “Committee to Save the World” – tweeted late in December (20/12/2017).

An MMT response to Jared Bernstein – Part 1

This view is erroneous in fact but representative of the demise of a true progressive opposition in the US.

I discussed this issue in detail in this blog (November 9, 2017) – When neoliberals masquerade as progressives.

Also, see this blog for my analysis of the track record of Lawrence Summers in the lead up to the GFC – Being shamed and disgraced is not enough (December 18, 2009).

With the idiocy of the Trump administration in full glare, the Democrats should have an open door to regain political control in the US.

But all they seem to obsess about are deficits.

As an aside, on the misleading way in which social media is used, I saw a tweet from a New York Times columnist (Bret Stephens) yesterday, which announced:

BretStephensNYT: What single payer looks like in Britain:…

The inference in Stephen’s tweet was that if the US pursued single payer medical care system it would end up like the British system.

The link was to this NYT article (January 3, 2018) – N.H.S. Overwhelmed in Britain, Leaving Patients to Wait.

It documented the difficulties the National Health System is facing as ideologically-motivated austerity cuts are hacking into the capacity of a formerly excellent health care system to survive.

The state of the British NHS at present tells you nothing about the effectiveness of single payer health systems. It just demonstrates what happens to public services when the government stops funding them.

I would urge subscribers to abandon the NYTs. It has become a neo-liberal mouthpiece.

Anyway, the issue of taxes and more was raised by Jared Berstein in his – Questions for the MMTers – and given his article reflected his curiosity and civility, I thought it would be worth responding because he raises some points that are often misunderstood by the broader MMT community even, as well as the wider audience.

I am also writing this from a global perspective, rather than a US-centric position. Every nation has institutional and cultural nuances that intervene in discussions about political realities.

It may be that the US has more institutional constraints on government than other nations. I doubt that and I am not ignorant of the institutional structure that the US government works within, including the legislative structure.

The point is that when you start digging into the specific structures you usually find commonality – that the elected government has the capacity to change things (change voluntary constraints it has previously embedded) if there is sufficient political will to do so.

For example, it is often claimed that the US central bank is ‘independent’ of the elected government, a point that Jared Bernstein makes (see below).

But the Board of Governors of the Federal Reserve “is a federal government agency consisting of seven members appointed by the President of the United States and confirmed by the U.S. Senate” (Source).

The Federal Reserve Act could also be amended at any time there is legislative will to allow the President to sack the central bank governor when he/she chooses.

Similar arrangements exists in most nations.

The point is that what looks like constraints on government are often just a reflection of the current political outlook and ideology and if there is sufficient support for change then the nation state typically has that power.

As we explain in our latest book – Reclaiming the State: A Progressive Vision of Sovereignty for a Post-Neoliberal World (Pluto Books, 2017) – the Right have used that legislative power to advance their own agenda while the Left has been duped into believing that globalisation, think tanks and lobby groups have rendered the nation state impotent.

Far from it, these powerful political forces (think tanks, lobby groups) have co-opted the state and its legislative machinery. It is just that the progressive side of politics still raves on about the dangers of deficits etc and refuses to organise properly around a truly progressive agenda.

Overheating is possible, and taxing is a lousy mechanism for dealing with it

This is the first thing that Jared Bernstein “doesn’t get” about Modern Monetary Theory (MMT).

He asserts that:

To dial back fiscal stimulus, MMT’ers argue for tax increases.

His objection is that tax increases are politically tricky to engineer and, “don’t happen quickly”. Further, there is a “huge industry to fight you tooth and nail”.

He thinks that the better way to stop an “overheating” is for the central bank to “take money out of the economy” because it can do that “without political interference”.

First, the view that the core (academic) MMT position relies solely on tax increases for counter-cyclical macroeconomic stabilisation is not accurate.

The misunderstanding arises from the discussion within MMT on the role of taxes, which has its roots in the functional finance literature developed by Abba Lerner in the 1940s.

MMT is emphatic that an intrinsic characteristic of a fiat currency system is that tax revenue is not required to fund government spending.

Please read my blog – Taxpayers do not fund anything – for more discussion on this point.

Within that discussion, the MMT literature indicates several other ‘functions’ that taxes play in the monetary system, none of them related to ‘funding’ government spending.

Note, as per above, it may ‘look as though’ taxes are financing spending – if the institutional machinery requires certain accounting machinations to be satisfied – but intrinsically it is not the case.

MMT says that the imposition of taxes creates unemployment within the non-government sector which can then be absorbed through appropriate government spending.

Which means that if there is mass unemployment, then, either taxes are too high or spending too low (or a mix of both).

MMT also points to the resource allocation impacts of taxation (for example, taxes on tobacco or carbon to discourage use).

MMT argues that taxation changes is one of several fiscal instruments that can be used to moderate or stimulate total spending in the economy, which then allows the government to regulate price pressures that arise from nominal demand outstripping the capacity of the economy to respond in real terms (producing goods and services).

Abba Lerner wrote in his 1943 article – Functional Finance and the Federal Debt – (page 39):

Government should adjust its rates of expenditure and taxation such that total spending in the economy is neither more nor less than that which is sufficient to purchase the full employment level of output at current prices.

This was his famous “steering wheel” analogy – where the government adjusts policies to keep the vehicle on the road!

Lerner outlined three fundamental rules of functional finance in his 1941 (and later 1951) works, the first rule being that:

The government shall maintain a reasonable level of demand at all times. If there is too little spending and, thus, excessive unemployment, the government shall reduce taxes or increase its own spending. If there is too much spending, the government shall prevent inflation by reducing its own expenditures or by increasing taxes.

Please read my blog – Functional finance and modern monetary theory – for more discussion on this point.

However, for the record, Lerner’s 1977 article – From Pre-Keynes to Post-Keynes – published in Social Research, 44(2), pp.387-415 is much more nuanced. The link, by the way, is to JSTOR and a subscription is needed.

He was reflecting on policy in the context of stagflation which emerged following the OPEC oil shocks and paved the way for the neoliberal dominance.

Lerner essentially argued that the propensity for wage-price spirals to form as cost pressures mount (say, from an imported raw material rise) made it difficult to apply the simple ‘steering wheel’ approach – turning on the net spending spigot (via tax and/or spending changes).

MMT also consistently advocates government efforts to ensure that real wages broadly rise in proportion to labour productivity growth, as an inflation-suppressing strategy.

In this light, Lerner suggested a range of wage-price measures in his 1977 article. In other words, he introduced additional policy tools to discipline inflation biases.

He thought that unless these institutional biases towards inflation were addressed, ‘demand management’ policies will not work very well.

It is important, though, to understand that he was talking about stagflation, which he separated into two components: “stagnation and inflation”.

He wrote that:

The stagnation component (inadequate total spending at the current wage and price level to yield full employment) calls for macroeconomic governmental measures for increasing total spending. The inflation component, which cannot be excess-demand inflation, calls for microeconomic market adjustments of wages and prices, with the government only internalizing an externality by administering the wage-increase permits.

In other words, an understanding of the context is important. If inflation is accelerating as a consequence of excessive spending yet unit cost pressures are not present, then the basic principles of functional finance remain valid.

One might also read Mathew Forstater’s Levy Working Paper No. 254 – Toward a New Instrumental Macroeconomics: Abba Lerner and Adolph Lowe on Economic Method, Theory, History and Policy – for an excellent account of the way in which fiscal policy can work.

One would argue that the current neoliberal period, where real wages growth have lagged significantly behind labour productivity growth, that any inflationary pressures are likely to be of the more simple type – excessive nominal spending growth.

But the point is that raising taxes to stifle such excessive nominal spending is one option only but not necessarily the preferred MMT option.

Typically, a mix of fiscal responses will be required depending on the circumstances, the existing tax and spending structure, the state of income and wealth distribution in the particular country, how fast inflation is accelerating, and more.

The core (academic) MMT group would never say that any national government should rely on taxes to fight an inflationary spiral.

Further, governments have shown they can cut spending quickly and still prosper politically, if the political forces are aligned.

There are many areas of government spending that can be wound back without impacting significantly on the well-being of most of us or invoking distributional consequences that would have negative impacts at the lower end of the income distribution.

For example, consider the incidence of corporate welfare, which includes “a government’s bestowal of money grants, tax breaks, or other special favorable treatment for corporations”.

The so-called “Socialism for the rich, capitalism for the poor” or “privatising the gains and socialising the losses” is rife in most fiscal systems, especially in this neoliberal period.

While conservatives rail against governments spending on public health and education or income support for the poor, the reality is that corporate welfare spending often dwarfs these progressive targets.

The 1993 article by Daniel Huff and David Johnson – Phantom Welfare: Public Relief for Corporate America – published in the Social Work journal [38(3), pp.311-16)] – quantified the extent wo which federal subsidies in the US benefit the corporate sector.

In 1993, they estimated this largesse to be “in excess of $150 billion a year”, which “represent a major redistribution of wealth that partially accounts for the growing gap between the rich and the poor”.

Not much has changed since they published their research.

There are huge opportunities within the military-industrial complex in the US to make cyclical cuts, which will attenuate nominal demand growth and multiply through the economy.

A social democratic government elected on a broad progressive consensus and a willingness to acknowledge MMT principles would be in a position to resist the neoliberal aspirations of those corporate interests who would fight “tooth and nail”.

During the full employment era following the Second World War and before the neoliberal dominance, governments regularly resisted the conservative lobby groups, which was one of the reasons the corporate sector in the US engaged Lewis Powell.

Please read my blog – The right-wing counter attack – 1971 – for more discussion on this point.

Neoliberalism is not inevitable.

There are other considerations.

Significant forward planning is required to ensure that the fiscal policy can be relatively responsive to the cycle. MMT economists are fully aware of the technical, legislative and implementations lags that can accompany large-scale public spending.

But well thought out preparation and well planned projects can allow the government to turn on spending fairly quickly in a downturn and turn it off (or restrict it) in times of high pressure.

For example, the decision by Norwegian authorities to fast-track the construction of Oslo Airport at Gardermoen was a highly effective fiscal intervention to ease the pain of the 1992 recession.

While the location of the airport was controversial, the intervention was effective and finite. It also carried scale such that components could be expanded or restricted at fairly short notice to meet with the changing cyclical conditions.

Another good example is the highway projects in Japan. The Japanese government has a well-designed infrastructure plan in place that allows it to expand and contract government spending to extend the highway and related infrastructure (bridges, waterways etc) to suit cyclical conditions.

This type of spending can be highly responsive with minimal lags.

There are many other examples.

Further, MMT economists realise that the expansionary and contractionary capacity of tax changes are dollar-for-dollar less than for public spending changes.

Tax cuts in a downturn are in part saved and are subject to longer lags than government spending injections. The reverse occurs in an upturn with tax hikes.

Tax changes operate through shifting private spending decisions as disposable income is impacted. Those behavioural shifts take time.

Whereas government spending shifts are direct and can add or subtract dollars to and from the economy virtually immediately.

So to claim that MMT economists are biased towards the use of tax hikes to pull back an overheating economy is more than inaccurate.

Finally, MMT economists also recognise that inflation can come via exchange rate movements, which may require specialised policy responses.

For example, if there are speculative capital outflows which put downward pressure on the currency in the foreign exchange markets then MMT economists would suggest capital controls are an effective way to stabilise the currency and prevent the inflationary impacts emerging. Iceland’s recent use of capital controls demonstrates the effectiveness of this strategy.

But it is true that discretionary cuts in spending and/or increases in taxes will create unemployment, which is the way that generalised fiscal stabilisation works to curb excessive spending.

In this context, MMT also emphasises the role of the automatic stabilisers, which exploit the inherent fiscal parameters to moderate spending changes (up or down) as the economic cycle changes.

The automatic stabilisers serve to moderate the effects of income changes on spending in two ways. First, the initial income changes impacts on disposable income. Second, changes in disposable income then translate into spending shifts.

Once again, one needs to analyse the specific situation. The automatic stabilisers in the US are somewhat weaker than in other advanced nations because the welfare state is less pervasive.

But the difference has been estimated to be relatively small (see Automatic stabilisers and the economic crisis in Europe and the US.

In general, the cycle impacts on the tax revenue that the government receives. When times are bad and output and employment falls, tax revenue declines, which pushes out the fiscal deficit and attenuates, to some extent, the decline in total spending.

Remember that part of the income that is lost would have been taxed anyway.

But if I was to consider this impact in the US, I would conclude that the stabilisation coming from the tax structure is fairly powerful.

It appears that when the US economic cycle improves tax revenue booms. The Clinton surpluses point to that as do the way in which the fiscal deficit has declined sharply in the US in the current period despite there being significant remaining labour underutilisation remaining.

But can we rely on that degree of stabilisation to ensure there is enough counter-cyclicality in-built into the fiscal structure? I doubt it.

Which is why MMT advocates strengthening of the automatic stabilisers via the – Job Guarantee – a major innovation that many critics seem to hate.

Once you understand the mechanisms through which the Job Guarantee work, you soon realise, for example, that progressives who advocate Basic Income Guarantees have no concept of an inflation anchor.

The link above takes you to the vast number of blogs I have written about the topic.

Essentially, the Job Guarantee renders the automatic stabilisers very powerful and ensures that government spending become highly counter-cyclical.

By shifting workers from the inflating sector to a fixed price sector, the spending associated with the Job Guarantee will provide that inflation anchor without creating mass unemployment and increased poverty, typically associated with contractionary fiscal policy.

The Job Guarantee is an example of spending on a price rule rather than a quantity rule, the latter being the typical fiscal approach. In other words, the government announces a fixed wage at which it will employ any number of workers who cannot find work elsewhere.

Whereas a quantity rule, allocates a certain monetary outlay and then competes at market prices for the resources. Such an approach cannot provide an inflation anchor.

I won’t go into any more detail about that (for space reasons).

The point is that the Job Guarantee creates what I have called ‘loose’ full employment to distinguish the resulting state from an economy where all labour is being employed at market-determined wages.

The desirable outcome is that the Job Guarantee pool is low. But its cyclicality provides a powerful inflation anchor.

But the application of the policy still requires that the government initiates the transfer of workers from the inflating sectors of the economy to the fixed price sector (JG) through spending cuts and/or tax increases.

That is the reality of a monetary economy where nominal aggregates compete for real resources.

Fortunately, we do not get many periods where a government has to invoke these type of measures.

I note that some commentators (no links to stop them getting unwarranted advertising revenue – click bait) have tried to piggy back off Jared Bernstein’s queries by claiming that Modern Monetary Theory (MMT) does not have an inflation theory.

Either they cannot read, cannot understand what they read, have never watched videos from key MMT academics on the subject or are just plain spiteful and seeking attention. Probably the latter.

There is a well articulated theory of inflation embedded in the academic MMT literature and I have written and spoken hundreds of thousands of words on the topic (which was after all the topic of my PhD thesis).

Please read my blog – I wonder what the hell I have been writing all these years – for more discussion on this point.

The MMT textbook (Mitchell, Wray and Watts) has a very well articulated section on inflation. See the introductory version –

The more advanced text will be published by Macmillan in October 2018, which offers a more detailed analysis of how inflation occurs and what can be done about it.

How does a central bank ‘take money out of the economy’?

In rejecting the use of fiscal policy to stabilise an ‘overheating’ economy, Jared Bernstein advocates a reliance on the central bank.

He wrote:

That’s why we have a Federal Reserve that can quickly and without political interference decide to take money out of the economy (to be clear, monetary policy also has distributional implications). That seems like an immeasurably more reliable way to handle the overheating problem, but I don’t think the MMT crowd agrees, or at least I don’t understand where the Fed and interest rates exist is their cosmology.

What does the claim “take money out of the economy” mean?

Does he think that the central bank ‘controls’ the money supply which was the basis of Monetarism in the late 1960s and beyond? Attempts to do so failed badly and were quickly abandoned.

If he believes that then you know he doesn’t understand the way the central bank and the commercial banking system operates.

The fact is that within their remit, central banks cannot control the money supply which means they cannot take money out of the economy as he suggests.

Sure enough, as per above, the US government could change the Federal Reserve Act to allow the Board of Governors to confiscate
reserves from the banking system, which would just compromise financial stability and be a stupid policy. It would have no impact on bank lending, which we know is not reserve constrained.

The main policy tool that the Federal Reserve and all central banks have at their disposable is the ability to set the short-term policy interest rate, which then condition the term structure (other interest rates at longer maturities).

Certainly, the central bank can alter this rate at will. But whether that capacity is sufficient to act as a powerful counter-stabilisation force is moot. MMT academics definitely do not think so.

We have seen many things during the crisis that bear on policy effectiveness. One of the most glaring things that should be obvious to anybody who has been keeping their eye on the ball is that central bank policy tools are very ineffective in influencing the inflation rate.

Central banks around the world have been running near zero interest rates at the short end for nearly a decade now, with the concomitant reductions in the investment rates at the longer maturities.

They have been swapping reserves for government bonds in massive proportions – thinking that the extra cash would lead to a flood of lending and push up prices.

Nary a nudge in the official price indexes has been observed.

MMT economists indicated all along that such quantitative easing would not stimulate aggregate spending. The only way it could have was via the reductions in the investment rates in the maturity ranges the central banks were targetting.

The QE increased demand for bonds in those ranges which suppressed yields and rates associated with other financial assets within that range thus fell as well.

But with the parlous state of the economy, not even lower interest rates would stimulate demand for loans.

The point is that the demand for loans is not determined by the volume of bank reserves. Rather it depends on the expectations of returns and in a gloomy environment no one will borrow even if credit is cheap.

The same works in reverse. In high pressure times, the expectation of high profits would be strong and the demand for credit would remain strong even if rates went up.

It is possible that if the central bank hiked interest rates to very high levels that widespread bankruptcy would occur in the home mortgage market and that would impact on overall spending.

But no responsible government would allow that sort of counter-stabilisation to be used as the default given the devastation it would cause and the fact that it would impact badly on those least able to defend themselves (low income groups etc).

This also raise the additional issue that MMT economists point out.

Monetary policy has ambiguous impacts. An interest rate rise benefits creditors but punished debtors. What is the net effect of this distributional shift? No central banker can tell you.

I thought the Financial Times article (October 5, 2017) – Fed has no reliable theory of inflation, says Tarullo – was interesting in this regard.

It interviews a recently retired US Federal Reserve Board member (Daniel Tarullo), who told the FT that:

The substantive point is that we do not, at present, have a theory of inflation dynamics that works sufficiently well to be of use for the business of real-time monetary policymaking.

Further, MMT economists note that the time lags in the use of monetary policy are uncertain. Even if there is a spending sensitivity to large shifts in interest rates (small shifts are unlikely to carry any sensitivity), the impact works indirectly through changes in the cost of credit which then have to alter other spending behaviour.

And, unlike fiscal policy which can be targetted by demographic cohort and spatially attenuated (to impact on specific regions), monetary policy inasmuch as it works at all is a blunt tool – a short of shotgun approach.

Finally, there is some thought that interest rate rises push up inflationary pressure given their impact on the cost structure of firms that have price setting power.

So it is true that MMT economists favour fiscal policy as the main counter-stabilisation tool over monetary policy. Monetary policy is not an effective tool as the last decade has demonstrated.


I will conclude this series tomorrow with Part 2 where I consider whether a central bank can obstruct a government intent on fiscal stimulus/contraction; whether at full employment the fiscal balance has to be zero (it does not!) and whether in order to spend the national government needs to raise taxes.

That is enough for today!
