A budget surplus equivalent to 1 per cent of GDP ratio necessarily reflects a more contractionary fiscal policy stance than a budget deficit equivalent to 1 per cent of GDP.


Question 1:
A budget surplus equivalent to 1 per cent of GDP ratio necessarily reflects a more contractionary fiscal policy stance than a budget deficit equivalent to 1 per cent of GDP.
The answer is False.
The actual budget deficit outcome that is reported in the press and by Treasury departments is not a pure measure of the fiscal policy stance adopted by the government at any point in time. As a result, a straightforward interpretation of movements in the actual outcome is difficult.
While it is true that a larger deficit supports aggregate demand more than a smaller deficit we cannot conclude that this is reflecting the intent of discretionary fiscal policy stance.
To understand that point we need to realise that the actual budget outcome as being the sum of two components: (a) a discretionary component – that is, the actual fiscal stance intended by the government; and (b) a cyclical component reflecting the sensitivity of certain fiscal items (tax revenue based on activity and welfare payments to name the most sensitive) to changes in the level of activity.
The former component is now called the “structural deficit” and the latter component is sometimes referred to as the automatic stabilisers.
The structural deficit thus conceptually 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 budget goes into deficit which might lead people to think the “government” is expanding the economy.
So just because the budget 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 blogs, 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 Budget Balance was a hypothetical construction of the budget balance that would be realised if the economy was operating at potential or full employment. In other words, calibrating the budget position (and the underlying budget 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 budget balance into (in modern terminology) the structural (discretionary) and cyclical budget balances with these unseen budget components being adjusted to what they would be at the potential or full capacity level of output.
The difference between the actual budget outcome and the structural component is then considered to be the cyclical budget 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 budget 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 budget 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 budget 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 budget outcome is presently.
So you could have a downturn which drives the budget into a deficit but the underlying structural position could be contractionary (that is, a surplus). And vice versa.
So the fact that the budget deficit is rising might actually indicate that the fiscal austerity program is more contractionary that the Government initially estimated and the automatic stabilisers (loss of tax revenue etc) are more than offsetting the discretionary cuts in net public spending.
It follows that we could get a situation where the budget deficit of 1 per cent of GDP actually reflected a structural surplus of say 2 per cent of GDP and the automatic stabiliser (cyclical) component creating a 3 per cent swing to the deficit.
In the same light, the 1 per cent surplus recorded could reflect a structural deficit of, say 1 per cent, with the a stronger economy pushing the cyclical component of 2 per cent.
The latter situation would be reflect an intent to stimulate the economy, while the former to deliberately contract the economy.
