Find below the full text and charts from David Gruen, Head of Treasury’s Macro Group, on productivity and structural change. This is a good speech with which I agree by and large. I only have one major disagreement with it and that is the happy chart showing the slow decline in Australia’s terms of trade boom (chart 4). Commodity booms do not end slowly, they bust. This disrupts Gruen’s conclusion that firms should simply be allowed to adjust to the pressures of the boom, like a high dollar, via improved productivity. If you had 15% margins in 2007 and improved your productivity at an above average 2% per annum, you’re still wiped out by the currency gain. And if it is temporary then that’s a highly productive business that’s been wiped out not because it can’t compete but because markets went nuts for commodities for a few years. If you accept the boom is temporary then your view of how competitive pressures should shape productivity shifts. If it doesn’t, when the commodity crash comes you face a black hole where productive industry used to be.
Productivity and Structural Change
It is a great pleasure to be asked to speak on the subject of economic policy challenges in 2012 and beyond.1
Economic policy challenges are always in generous supply. Rather than seeking to span the breadth of the subject, in the time available I would like to make a few comments about a couple of the bigger challenges for the future: productivity growth and structural change.
Productivity is a measure of how efficiently an economy is operating. Productivity growth comes about by doing things better today—more efficiently—than we did yesterday.
Today, I want to talk about the economics of productivity growth and what happens below the surface, particularly the importance of competitive forces in driving innovation and improving the allocation of resources.
Looking back at two decades of income growth
Perhaps a good place to start is with the purpose of economic policy. Broadly, economic policy is about improving the wellbeing of the Australian people today, and in the future.2 An aspect of improving wellbeing is lifting material standards of living over time, measured by the amount of income we have available. It is only one aspect, but an important one. Increasing incomes over time means not only that people have the capacity to buy more goods and services. It also means that potentially more tax revenue is available to achieve other public ends, such as providing public health care or improving environmental outcomes.In the past two decades, the Australian economy has delivered strong income growth, though the sources of that growth have changed markedly. Chart 1 shows average annual growth in real gross national income (GNI) per person, which is a measure of the purchasing power of income Australians earn from production, net of income flows to foreign owners of factors of production.
The economic recovery after the recession of the early 1990s was led by strong productivity growth. Australia, together with the United States and a small number of other countries, saw a resurgence in productivity growth to rates not seen since the 1960s.3
The resurgence was led by service sector industries, like wholesale trade and banking, that seized on new advances in information and communication technology to transform the way they did business (Parham, Roberts and Sun 2001). This was supported by continued productivity growth in industries like telecommunications and electricity, gas and water supply arising from substantial reductions in their workforces following corporatisation and privatisation of their operations, and a reduction in their levels of investment. Productivity levels in these industries rose towards the international technological frontier.
In the past decade or so, the economy has taken a different path. The boom in Australia’s terms of trade has lifted the exchange rate, lowering the cost of imported goods and boosting the purchasing power of Australian incomes. This has added 1.2 percentage points per year to growth in average incomes since the turn of the century, in contrast to previous decades when the terms of trade made no significant contribution.
The labour market has also done a more effective job of spreading the benefits of economic growth than it did in the 1990s. Overall, there has been an increase in hours worked per capita, with a sharp rise in the participation rate to the highest level on record more than offsetting a decline in average hours worked, particularly by full-time workers. The boom also has seen a decline both in the average rate of unemployment and in the geographic dispersion of the unemployment rate across the economy (Gruen, 2011).
On the other hand, it is now widely recognised that growth in Australian labour productivity—output per hour worked—has slowed since around the turn of the century, notwithstanding stronger data in the past few quarters. Labour productivity growth explained less than half of the growth in average incomes since the turn of the century, compared to an average of around 90 per cent of income growth over the four previous decades.
Multifactor productivity—the output produced from a bundle of labour and capital inputs—has scarcely grown at all this decade (Chart 2). While the deterioration in performance is partly due to unusual developments in mining and utilities, the slowdown from the 1990s is broadly evident across most industries.
Note: Data are for 16 market sector industries. 2011-12 labour productivity data are the average of the first three quarters.

While for households as a group, the mining boom and the higher exchange rate have delivered unambiguously positive benefits in the form of higher average incomes and increased purchasing power, these developments have had a more mixed effect on firms, their owners and the people employed in them.
There has been rapid growth in mining firms, and robust growth in a range of domestic service industries. On the other hand, manufacturers are continuing to come under pressure from competitors in China and other emerging markets, a process that may continue for some considerable time to come.
Some other parts of the economy that depend on household borrowing and spending are also facing pressure as households increase their saving rates to more historically normal levels.4 For some retailers, migration of spending to the internet and away from bricks-and-mortar stores has compounded this weakness. In banking, household demand for loans is growing more slowly following two decades that saw growth rates consistently running ahead of growth in household income. These changes are likely to be enduring.
Labour market trends show this bifurcation in growth (Chart 3). Over the three years since May 2009, employment in agriculture, manufacturing, construction, wholesale and retail trade, and transport, postal and warehousing services has fallen by a combined 140,700 people. At the same time, employment in the rest of the economy increased by 733,000 people, with the mining sector alone accounting for 120,400 jobs. Most households that have lost jobs are finding new ones and benefiting from the mining boom.

The flexible exchange rate has contributed to the pressure facing some industries in recent years as part of its role in maintaining macroeconomic stability. As a shock absorber, it allows the economy to benefit from the increase in demand in one sector without leading to generalised wage and price pressures.5 The significant restraint it imposes on other parts of the economy helps ensure that the economy overall does not overheat.6
In terms of growth in average incomes, however, it is as well to recognise that, in at least two ways, the tail-breezes of the past are becoming the head-winds of the future.
The ageing of the Australian population has added to labour utilisation over the past four decades as the proportion of children in the population has fallen steadily since the baby boom. But Australia’s aggregate labour force participation rate has now hit a sweet spot. The same process of ageing will detract from labour force participation in future, and hence also from growth in output per person, as the baby boomer generation moves into retirement. That process is already underway (Chart 4).
Note: Working age population is the share of 15 to 64 year olds in the population.
Source: ABS cat. no. 5206.0, 3101.0, 3105.0.65.001, and Treasury projections from the 2012-13 Budget.The terms of trade have probably also peaked. Output prices in the mining sector rose to extraordinary heights because the surge in demand, led by Chinese growth, surprised the mining industry, which had insufficient capacity in place to meet demand. There is now an enormous pipeline of mining investment. And every year sees more output come on stream, in Australia and abroad. This process will likely see the mining sector continue to expand as a share of the Australian economy for some time, with a commensurate expansion in the volume of mining exports. Our projections imply, however, that while prices will remain elevated compared to historical experience, they are expected to trend lower over time as global supply expands.
So in terms of generating income growth, the ageing of the population and the terms of trade are likely to work against us in future, rather than for us.
Against this background, productivity improvement will again become the dominant determinant of growth in Australian incomes, as it has been for most of our history.
How, then, do we become more productive?
Productivity: evidence from the firm level
The drivers of productivity growth can be separated into two sets of explanations: the resources and capabilities available in the economy; and how those resources are applied by firms in production.It is widely recognised that governments play an important role in supporting the productive capability of the economy. This includes through investment in education and training, science and research, and infrastructure. Government involvement in these sectors is important. Markets left to their own devices will tend to result in too little investment where there are social or spill-over benefits to the broader community beyond the returns available to a private investor.
However, I want to focus instead on the role of the firm in productivity growth. The decisions made by individual firms in the Australian economy, and the interactions between them, will be a key driver of future productivity growth. Governments influence the environment in which firms engage with each other and make investment and production decisions. They set the rules of the game, if you like, and affect the incentives that firms face, and their flexibility to respond.
Recent international research into the drivers of productivity growth has examined the productivity of individual firms and the movement of resources between them.7 Australian firm dynamics have, to date, been studied to a lesser degree.
The focus on the firm reveals that aggregate productivity grows in a couple of different ways. One source is technical improvement. This is innovation within the firm. It can occur because of the development of new technologies that push out the productivity frontier, or through catch up of firms behind the frontier.
Technical improvement partly comes about through research and development within the firm, or in partnership with the formal research sector. But as a small country, most of the technology put into production in Australia is first developed overseas. Only a small fraction of innovative firms do things that are genuinely new to the world or new to the industry (Chart 5). What usually distinguishes leading organisations is not so much their ability to create knowledge, but rather their ability to absorb technology developed elsewhere and apply it to their own circumstances.

Note: Proportions are for innovating businesses only. Businesses could provide more than one answer.
Source: ABS cat. no. 8158.0.When firms innovate, the overriding motive is the pursuit of profits. Three-quarters of innovative firms report undertaking innovation to improve profits. Another motive is the firm’s position compared to its rivals. Around two-fifths of innovative firms undertook innovation to increase or maintain their market share, and a quarter report needing to develop more competitively priced products (Chart 6).

Source: ABS cat. no. 8158.0.Productivity also grows because of the reallocation of factors of production from low productivity firms to high productivity firms, the exit of low productivity firms and the entry and maturation of new businesses with bright ideas. Indeed, the dispersion in firm performance is remarkable. Analysis of Australian firms in the 1990s found that labour productivity at the 90th percentile was more than four times the level at the 10th percentile of the distribution (Bland and Will 2001).8 Differences of a similar size have been found in international studies. These differences are likely only partly explained by differences in capital investment: international evidence suggests that in narrowly defined industries the multifactor productivity level at the 90th percentile is typically about twice the level at the 10th percentile of the distribution (Syverson 2004b).
Firm level studies show that, even in periods of robust growth in the economy as a whole, there is considerable turmoil. According to the Australian Bureau of Statistics, around 8 per cent of Australian firms close down every year. Churn is particularly savage in the early years. Around two-fifths of all new firms in Australia exit in less than four years.9
With such large differences in productivity levels and rapid rates of firm turnover it is perhaps not surprising that the movement of resources and market share between firms from year to year is a significant force contributing to productivity growth. International estimates suggest that the net effect of entry and exit typically accounts for between one-fifth and one-half of labour productivity growth over time.10 In high-technology industries, in particular, start-ups play an important role in promoting technological adoption and experimentation. Policies that act to slow the movement of resources will tend to limit this source of productivity improvement.
Management practices
A complementary approach to understanding productivity at the firm level is to focus on management practices. The idea is that management, like productivity, is all about how well resources are used in production. If management practices can be rated as good or bad, and aggregated to produce an overall management score, then this can provide insight into the sources of productivity differences across firms and across countries.As it turns out, a major exercise has been underway for some time to collect data on the management practices of more than 9000 medium and large manufacturing firms in 20 countries.11 Management performance is judged based on interviews with plant managers that are designed to reveal the extent to which companies: monitor what goes on inside firms and use this information for continuous improvement; set targets and track outcomes; and promote and reward employees based on performance.
Based on this methodology, management practices in Australia are mid-range. We are well below top performers like the United States, Germany, Sweden, Japan and Canada, but more similar to France, Italy and the United Kingdom (Chart 7).
