THE CHANGING MACRO POLICY MIX

Economics Seminar Day, Pymble Ladies’ College, Friday, June 13, 2014


The mangers of the macro economy have various economic policy objectives. They also have various instruments, or tools, available to use to meet those objectives. So they have to decide which instruments are best-suited to use to achieve which objectives. This choice of ‘policy mix’ is fairly settled, but does change over time in line with changing circumstances and changing views. The other thing that changes with the economy’s circumstances - and particularly its present position in the business cycle - is the ‘stance’ or setting of the key policy instruments.

I’m going to discuss four objectives: internal balance, external balance, fiscal sustainability and faster growth with greater flexibility. Then I’ll discuss the three instruments we use to achieve those four objectives: monetary policy, fiscal policy and micro-economic policy. I hope this will help you put together a lot of the topics you’ve learnt about this year, by taking you up in a helicopter, so to speak, and letting you look down on the whole course and see how it fits together.

Internal balance

Achieving internal balance is the single most important objective of the macro managers. It means achieving ‘full employment and price stability’ or, in more modern language, low unemployment and low inflation. The RBA regards its inflation target - ‘to maintain inflation between 2 and 3 pc, on average, over the cycle’ - as the achievement of ‘practical price stability’ and regards full employment as being the level of the non-accelerating-inflation rate of unemployment (the NAIRU) - that is, the rate below which unemployment can’t fall without labour shortages leading to an upsurge in wage and price inflation. It could thus be regarded as the lowest sustainable rate of unemployment. Economists’ best guess is that, at present, the NAIRU is sitting at about 5 pc, meaning the economy at present is travelling at less than full capacity.

The other way to think of internal balance is that it involves achieving a fairly stable rate of growth. Macro management aims to be ‘counter-cyclical’ - to speed the economy up when demand is growing too slowly and slow it down when demand is growing too fast. So macro management is also known as ‘demand management’ and ‘stabilisation policy’. The greatest swearword in demand management is to call some policy decision ‘pro-cyclical’ - something that will increase the amplitude of the business cycle rather than narrowing it.

External balance

The objective of external balance (or external stability) was a hangover from the world of fixed exchange rates, before the Aussie dollar was floated in 1983. Sometime after the election of the Howard government in 1996, however, academic economists led by the ANU’s John Pitchford finally succeeded in convincing Treasury that seeking to influence the CAD was not an appropriate objective of macro management. In the early 2000s, the Howard government quietly abandoned external stability as a policy objective. This has not changed under subsequent governments.

Fiscal sustainability

In the 2012 budget papers, the Gillard government formally articulated a new macro policy objective: ‘fiscal sustainability’. This means avoiding the build-up of an excessive stock of government debt as a consequence of many years of running budget deficits. The perils of excessive debt are now painfully apparent in Europe, where the financial markets’ unwillingness to continue funding some governments is forcing them to adopt policies of ‘austerity’ that are actually counterproductive (pro-cyclical).

Faster growth, with greater flexibility

It was under the Hawke-Keating government (1983 to 1996) that the policy makers acquired another explicit objective: faster economic growth, combined with a more flexible economy - one capable adapting to economic shocks (shifts in the aggregate demand or aggregate supply curves) without generating as much inflation and unemployment. Stable economic growth minimises inflation and unemployment, whereas faster growth in GDP per person causes a faster rise in material living standards.

That brings us to the end of the policy objectives, so now let’s look at the three policy instruments used over the years.

Monetary policy

Monetary policy - the manipulation of interest rates to influence the strength of demand - is conducted by the RBA independent of the elected government. Monetary policy has been assigned the objective of achieving internal balance. The 2012 budget papers said monetary policy plays ‘the primary role in managing demand to keep the economy growing at close to capacity, consistent with achieving the medium-term inflation target’.

Monetary policy is conducted in accordance with the inflation target: to hold the inflation rate between 2 and 3 pc, on average, over the cycle. The primary instrument of monetary policy is the overnight cash rate, which the RBA controls via market operations.

Fiscal policy

Fiscal policy - the manipulation of government spending and taxation in the budget - is conducted according to the Abbott government’s medium-term fiscal strategy: ‘to achieve budget surpluses, on average, over the medium term’. The 2012 budget papers nominated a new and different role for fiscal policy: ‘the primary objective of fiscal policy is to maintain the budget in a sustainable position from a medium-term perspective’. That is, the primary objective of fiscal policy is now maintaining ‘fiscal sustainability’.

However, it has also been made clear the budget retains an important role in assisting monetary policy achieve internal balance. How? By allowing the budget’s automatic stabilisers to be unimpeded in doing their job of helping to stabilise demand as the economy moves through the business cycle. The stabilisers bolster aggregate demand when private demand is weak and restrain aggregate demand when private demand is strong. The latter process is known as ‘fiscal drag’ - which is, of course, a helpful thing when you’re trying to keep the growth rate stable.

What does it mean to say fiscal policy’s primary objective is to achieve fiscal sustainability but the automatic stabilisers must be free to assist monetary policy in attaining internal balance? It means the policy makers are drawing a very Keynesian distinction between the effect of the automatic stabilisers (producing the ‘cyclical component’ of the budget balance) and the operation of discretionary fiscal policy (producing the ‘discretionary component’ of the budget balance). It’s discretionary fiscal policy that’s used to achieve fiscal stability over the medium term.

Everything I’ve just said about the modern roles of fiscal policy is consistent with the ‘medium-term fiscal strategy’. This strategy has been carefully worded to, first, permit the free operation of the automatic stabilisers and, second, permit the use of discretionary fiscal policy to stimulate the economy during a recession - provided this stimulus is withdrawn (wound back in) as the economy begins to recover. That is, the strategy has been designed to accommodate what you could call ‘symmetrical Keynesianism’.

Micro-economic policy

Micro-economic policy (also known as structural policy) was recognised as a policy instrument when the Hawke-Keating government began pursuing what it called micro-economic reform. The objective of micro reform is faster growth, with greater flexibility.

Note that, despite its name, micro-economic policy is an instrument of macro management. What distinguishes it from the other instruments is that rather than working on the demand (spending) side of the economy, it works on the supply (production) side. As well, demand management has a short-term focus, whereas micro-economic policy works over the medium to longer term. Over the medium term, the rate at which the economy can grow is determined by the rate at which the economy’s ability to supply additional goods and services is growing.

Micro policy works mainly by reducing government intervention in markets to increase competitive pressure, which leads to increased efficiency and productivity. Much microeconomic reform since the mid-80s - including floating the dollar, deregulating the financial system, reducing protection, reforming the tax system, privatising or commercialising government-owned businesses and decentralising wage-fixing - is assumed by most economists to have led to a surge in the rate of productivity improvement in the second half of  the 90s.

Micro reform seems to have been more successful at making the economy more flexible and resilient in the face of economic shocks. Greater competition within many product markets, the floating of the dollar and the move from centralised wage-fixing to bargaining at the enterprise level, in particular, have greatly reduced the problem of cost-push inflation pressure and made the economy significantly less inflation-prone. It may also be argued the greater flexibility accorded to employers by industrial relations reform has made the economy less unemployment-prone, as shown by their changed response to staff retention (their preference for shorter hours rather than lay-offs) in the mild recession of 2008-09. The more flexible the economy becomes, the easier it is for the macro managers to achieve internal balance and a stable rate of economic growth.  

While micro reform focused initially on reducing government intervention to encourage efficiency, under subsequent governments the focus has shifted to achieving higher productivity by reforming and increasing the investment in human capital (education and training) and infrastructure.
