The Australian Treasury equates the Non-Accelerating Inflation Rate of Unemployment (NAIRU) with full employment and uses this to calibrate their structural deficit estimates. Accordingly, the structural deficits reported will typically be:
(a) biased downwards, indicating, that at any point in the business cycle, that the government fiscal stance is less expansionary than it actually is.
(b) biased upwards, indicating, that at any point in the business cycle, that the government fiscal stance is more expansionary than it actually is.
(c) difficult to assess because the Treasury forward estimates are subject to forecasting inaccuracy.
The answer is Option (b) – biased upwards thus indicating, at any point in the business cycle, that the government fiscal stance is more expansionary than it actually is..
The question also has one qualifying aspect to it – the use of the word typically – which means that in conventional practice the answer is as given but there are circumstances where the statement would not apply.
We are seeing the use of the term “structural deficit” more often in the public debate as the weak recovery ensues and the talk has turned to credible “exit” plans for fiscal policy.
The mainstream position that fiscal positionss should be balanced or in surplus (and that the deficits being experienced at present will need to be “paid” for by offsetting surpluses then leads commentators to conclude that any estimated structural deficit is a problem. I will briefly come back to that at the end of the discussion here.
But what is a structural deficit? Well it is the component of the actual budget outcome that reflects the chosen (discretionary) fiscal stance of the government independent of cyclical factors.
The cyclical factors refer to the automatic stabilisers which operate in a counter-cyclical fashion. When economic growth is strong, tax revenue improves given it is typically tied to income generation in some way. Further, most governments provide transfer payment relief to workers (unemployment benefits) and this decreases during growth.
In times of economic decline, the automatic stabilisers work in the opposite direction and push the budget balance towards deficit, into deficit, or into a larger deficit. These automatic movements in aggregate demand play an important counter-cyclical attenuating role. So when GDP is declining due to falling aggregate demand, the automatic stabilisers work to add demand (falling taxes and rising welfare payments). When GDP growth is rising, the automatic stabilisers start to pull demand back as the economy adjusts (rising taxes and falling welfare payments).
The problem is then how to determine whether the chosen discretionary fiscal stance is adding to demand (expansionary) or reducing demand (contractionary). It is a problem because a government could be run a contractionary policy by choice but the automatic stabilisers are so strong that the fiscal position goes into deficit which might lead people to think the “government” is expanding the economy.
So just because the fiscal position goes into deficit doesn’t allow us to conclude that the Government has suddenly become of an expansionary mind. In other words, the presence of automatic stabilisers make it hard to discern whether the fiscal policy stance (chosen by the government) is contractionary or expansionary at any particular point in time.
To overcome this ambiguity, economists decided to measure the automatic stabiliser impact against some benchmark or “full capacity” or potential level of output, so that we can decompose the budget balance into that component which is due to specific discretionary fiscal policy choices made by the government and that which arises because the cycle takes the economy away from the potential level of output.
As a result, economists devised what used to be called the Full Employment or High Employment ‘Budget’. In more recent times, this concept is now called the Structural Balance. As I have noted in previous blog posts, the change in nomenclature here is very telling because it occurred over the period that neo-liberal governments began to abandon their commitments to maintaining full employment and instead decided to use unemployment as a policy tool to discipline inflation.
The Full Employment Fiscal Balance was a hypothetical construction of the fiscal balance that would be realised if the economy was operating at potential or full employment. In other words, calibrating the fiscal position (and the underlying fiscal parameters) against some fixed point (full capacity) eliminated the cyclical component – the swings in activity around full employment.
This framework allowed economists to decompose the actual fiscal balance into (in modern terminology) the structural (discretionary) and cyclical fiscal balances with these unseen fiscal components being adjusted to what they would be at the potential or full capacity level of output.
The difference between the actual fiscal outcome and the structural component is then considered to be the cyclical fiscal outcome and it arises because the economy is deviating from its potential.
So if the economy is operating below capacity then tax revenue would be below its potential level and welfare spending would be above. In other words, the fiscal balance would be smaller at potential output relative to its current value if the economy was operating below full capacity. The adjustments would work in reverse should the economy be operating above full capacity.
If the fiscal position is in deficit when computed at the “full employment” or potential output level, then we call this a structural deficit and it means that the overall impact of discretionary fiscal policy is expansionary irrespective of what the actual fiscal outcome is presently. If it is in surplus, then we have a structural surplus and it means that the overall impact of discretionary fiscal policy is contractionary irrespective of what the actual fiscal outcome is presently.
So you could have a downturn which drives the fiscal position into a deficit but the underlying structural position could be contractionary (that is, a surplus). And vice versa.
The question then relates to how the “potential” or benchmark level of output is to be measured. The calculation of the structural deficit spawned a bit of an industry among the profession raising lots of complex issues relating to adjustments for inflation, terms of trade effects, changes in interest rates and more.
Much of the debate centred on how to compute the unobserved full employment point in the economy. There were a plethora of methods used in the period of true full employment in the 1960s.
As the neo-liberal resurgence gained traction in the 1970s and beyond and governments abandoned their commitment to full employment , the concept of the Non-Accelerating Inflation Rate of Unemployment (the NAIRU) entered the debate – see my blog posts – The dreaded NAIRU is still about and Redefing full employment … again!.
The NAIRU became a central plank in the front-line attack on the use of discretionary fiscal policy by governments. It was argued, erroneously, that full employment did not mean the state where there were enough jobs to satisfy the preferences of the available workforce. Instead full employment occurred when the unemployment rate was at the level where inflation was stable.
The estimated NAIRU (it is not observed) became the standard measure of full capacity utilisation. If the economy is running an unemployment equal to the estimated NAIRU then mainstream economists concluded that the economy is at full capacity. Of-course, they kept changing their estimates of the NAIRU which were in turn accompanied by huge standard errors. These error bands in the estimates meant their calculated NAIRUs might vary between 3 and 13 per cent in some studies which made the concept useless for policy purposes.
Typically, the NAIRU estimates are much higher than any acceptable level of full employment and therefore full capacity. The change of the the name from Full Employment Budget Balance to Structural Balance was to avoid the connotations of the past where full capacity arose when there were enough jobs for all those who wanted to work at the current wage levels.
Now you will only read about structural balances which are benchmarked using the NAIRU or some derivation of it – which is, in turn, estimated using very spurious models. This allows them to compute the tax and spending that would occur at this so-called full employment point. But it severely underestimates the tax revenue and overestimates the spending because typically the estimated NAIRU always exceeds a reasonable (non-neo-liberal) definition of full employment.
So the estimates of structural deficits provided by all the international agencies and treasuries etc all conclude that the structural balance is more in deficit (less in surplus) than it actually is – that is, bias the representation of fiscal expansion upwards.
As a result, they systematically understate the degree of discretionary contraction coming from fiscal policy.
The only qualification is if the NAIRU measurement actually represented full employment. Then this source of bias would disappear.
Why all this matters is because, as an example, the Australian government thinks we are close to full employment now (according to Treasury NAIRU estimates) when there is 5 per cent unemployment and 9.5 per cent underemployment (and about 1.5 per cent of hidden unemployment). As a result of them thinking this, they consider the structural deficit estimates are indicating too much fiscal expansion is still in the system and so they cut back.
Whereas, if we computed the correct structural balance it is likely that the Federal fiscal deficit even though it expanded in both discretionary and cyclical terms during the crisis is now too contractionary.

Under a fiat monetary system, the absence of currency convertibility means:
(a) there is no reason for people to hold currency as a hedge against gold price falls.
(b) that the currency is only convertible into government bonds rather than gold.
(c) that the government can motivate people to exchange goods and services in return for public spending by fining anyone of working age who walks down the street.
The answer is Option (c) – that the government can motivate people to exchange goods and services in return for public spending by fining anyone of working age who walks down the street.
In a fiat monetary system the currency has no intrinsic worth. Further the government has no intrinsic financial constraint. Once we realise that government spending is not revenue-constrained then we have to analyse the functions of taxation in a different light. The starting point of this new understanding is that taxation functions to promote offers from private individuals to government of goods and services in return for the necessary funds to extinguish the tax liabilities.
In this way, it is clear that the imposition of taxes creates unemployment (people seeking paid work) in the non-government sector and allows a transfer of real goods and services from the non-government to the government sector, which in turn, facilitates the government’s economic and social program.
The crucial point is that the funds necessary to pay the tax liabilities are provided to the non-government sector by government spending. Accordingly, government spending provides the paid work which eliminates the unemployment created by the taxes.
It is the introduction of State Money (government taxing and spending) into a non-monetary economics that raises the spectre of involuntary unemployment. Involuntary unemployment is idle labour offered for sale with no buyers at current prices (wages).
Unemployment occurs when the private sector, in aggregate, desires to earn the monetary unit of account, but doesn’t desire to spend all it earns, other things equal. As a result, involuntary inventory accumulation among sellers of goods and services translates into decreased output and employment. In this situation, nominal (or real) wage cuts per se do not clear the labour market, unless those cuts somehow eliminate the private sector desire to net save, and thereby increase spending.
The purpose of State Money is for the government to move real resources from private to public domain. It does so by first levying a tax, which creates a notional demand for its currency of issue. To obtain funds needed to pay taxes and net save, non-government agents offer real goods and services for sale in exchange for the needed units of the currency. This includes, of-course, the offer of labour by the unemployed. The obvious conclusion is that unemployment occurs when net government spending is too low to accommodate the need to pay taxes and the desire to net save.
So the point is that for a fiat currency to be used in an economy, people in the non-government sector have to have a motive to get hold of it. The imposition of a tax obligation that can only be extinguished in the fiat unit of account provides that motive.
However, the government could impose any obligation, which could only be met by people in the non-government sector by acquiring the fiat currency and returning it to the government.
The fine would be one alternative to taxation to accomplish a “demand” for the particular fiat currency. Once people have to get hold of that currency they will willingly exchange goods and services in return for public spending.

When a sovereign government issues debt it logically:
(a) increases the assets that are held by the non-government sector $-for-$.
(b) has no impact on the overall holdings of assets held by the non-government sector $-for-$
(c) reduces the capacity of the private sector to borrow from banks because they use their deposits to buy the bonds.
The answer is has no impact on the overall holdings of assets held by the non-government sector $-for-$.
The fundamental principles that arise in a fiat monetary system are as follows.
- The central bank sets the short-term interest rate based on its policy aspirations.
- Government spending is independent of borrowing and the latter best thought of as coming after spending.
- Government spending provides the net financial assets (bank reserves) which ultimately represent the funds used by the non-government agents to purchase the debt.
- Fiscal deficits that are not accompanied by corresponding monetary operations (debt-issuance) put downward pressure on interest rates contrary to the myths that appear in macroeconomic textbooks about ‘crowding out’.
- The “penalty for not borrowing” is that the interest rate will fall to the bottom of the “corridor” prevailing in the country which may be zero if the central bank does not offer a return on reserves.
- Government debt-issuance is a “monetary policy” operation rather than being intrinsic to fiscal policy, although in a modern monetary paradigm the distinctions between monetary and fiscal policy as traditionally defined are moot.
National governments have cash operating accounts with their central bank. The specific arrangements vary by country but the principle remains the same. When the government spends it debits these accounts and credits various bank accounts within the commercial banking system. Deposits thus show up in a number of commercial banks as a reflection of the spending. It may issue a cheque and post it to someone in the private sector whereupon that person will deposit the cheque at their bank. It is the same effect as if it had have all been done electronically.
All federal spending happens like this. You will note that:
- Governments do not spend by “printing money”. They spend by creating deposits in the private banking system. Clearly, some currency is in circulation which is “printed” but that is a separate process from the daily spending and taxing flows.
- There has been no mention of where they get the credits and debits come from! The short answer is that the spending comes from no-where but we will have to wait for another blog soon to fully understand that. Suffice to say that the Federal government, as the monopoly issuer of its own currency is not revenue-constrained. This means it does not have to “finance” its spending unlike a household, which uses the fiat currency.
- Any coincident issuing of government debt (bonds) has nothing to do with “financing” the government spending.
All the commercial banks maintain reserve accounts with the central bank within their system. These accounts permit reserves to be managed and allows the clearing system to operate smoothly. The rules that operate on these accounts in different countries vary (that is, some nations have minimum reserves others do not etc). For financial stability, these reserve accounts always have to have positive balances at the end of each day, although during the day a particular bank might be in surplus or deficit, depending on the pattern of the cash inflows and outflows. There is no reason to assume that these flows will exactly offset themselves for any particular bank at any particular time.
The central bank conducts “operations” to manage the liquidity in the banking system such that short-term interest rates match the official target – which defines the current monetary policy stance. The central bank may: (a) Intervene into the interbank (overnight) money market to manage the daily supply of and demand for reserve funds; (b) buy certain financial assets at discounted rates from commercial banks; and (c) impose penal lending rates on banks who require urgent funds, In practice, most of the liquidity management is achieved through (a). That being said, central bank operations function to offset operating factors in the system by altering the composition of reserves, cash, and securities, and do not alter net financial assets of the non-government sectors.
Fiscal policy impacts on bank reserves – government spending (G) adds to reserves and taxes (T) drains them. So on any particular day, if G > T (a fiscal deficit) then reserves are rising overall. Any particular bank might be short of reserves but overall the sum of the bank reserves are in excess. It is in the commercial banks interests to try to eliminate any unneeded reserves each night given they usually earn a non-competitive return. Surplus banks will try to loan their excess reserves on the Interbank market. Some deficit banks will clearly be interested in these loans to shore up their position and avoid going to the discount window that the central bank offeres and which is more expensive.
The upshot, however, is that the competition between the surplus banks to shed their excess reserves drives the short-term interest rate down. These transactions net to zero (a equal liability and asset are created each time) and so non-government banking system cannot by itself (conducting horizontal transactions between commercial banks – that is, borrowing and lending on the interbank market) eliminate a system-wide excess of reserves that the fiscal deficit created.
What is needed is a vertical transaction – that is, an interaction between the government and non-government sector. So bond sales can drain reserves by offering the banks an attractive interest-bearing security (government debt) which it can purchase to eliminate its excess reserves.
However, the vertical transaction just offers portfolio choice for the non-government sector rather than changing the holding of financial assets.
Option (a) “increases the assets that are held by the non-government sector $-for-$” is thus incorrect.
Option (c) “reduces the capacity of the private sector to borrow from banks because they use their deposits to buy the bonds” is clearly not correct.
This is based on the erroneous belief that the banks need deposits and reserves before they can lend. Mainstream macroeconomics wrongly asserts that banks only lend if they have prior reserves. The illusion is that a bank is an institution that accepts deposits to build up reserves and then on-lends them at a margin to make money. The conceptualisation suggests that if it doesn’t have adequate reserves then it cannot lend. So the presupposition is that by adding to bank reserves, quantitative easing will help lending.
But this is a completely incorrect depiction of how banks operate. Bank lending is not “reserve constrained”. Banks lend to any credit worthy customer they can find and then worry about their reserve positions afterwards. If they are short of reserves (their reserve accounts have to be in positive balance each day and in some countries central banks require certain ratios to be maintained) then they borrow from each other in the interbank market or, ultimately, they will borrow from the central bank through the so-called discount window. They are reluctant to use the latter facility because it carries a penalty (higher interest cost).
The point is that building bank reserves will not increase the bank’s capacity to lend. Loans create deposits which generate reserves.
