Albanese's big chance to improve inflation, productivity and wages

Are Anthony Albanese and his ministers a bunch of nice guys lacking the grit to do much about their good intentions? Maybe. But this week’s announcement of a review of competition policy raises hope that the nice guys intend to make real improvements.

The review, which will provide continuous advice to the government over the next two years, has been set up because “greater competition [between Australia’s businesses] is critical for lifting dynamism, productivity and wages growth [and] putting downward pressure on prices”, Treasurer Jim Chalmers says.

As I wrote on Monday, the great weakness in our efforts to reduce high inflation has been our assumption that its causes are purely macroeconomic – aggregate demand versus aggregate supply – with no role for microeconomics: whether businesses in particular industries have gained the power to push their prices higher than needed to cover their increased costs.

But it seems Chalmers understands that. “Australia’s productivity growth has slowed over the past decade, and reduced competition has contributed to this – with evidence of increased market concentration [fewer businesses coming to dominate an industry], a rise in markups [profit margins] and a reduction in dynamism [ability to change and improve] across many parts of the economy,” he says.

The former boss of the Australian Competition and Consumer Commission, Rod Sims, had some pertinent comments to make about all this at a private business function last week.

He observes that “companies worked out long ago that the essence of corporate strategy is to gain market power and erect entry barriers. Profits from ‘outrunning’ many competitors from a common starting point are generally small; profits from gaining market power are usually large.

“Businesspeople know that when the number of competitors gets too large, price competition is often the result, and that this ‘destroys shareholder value’ or, alternatively put, helps consumers.”

Sims says the goals of growing and sharing the economic pie are being damaged in Western economies, and in Australia, by inadequate competition leading to market power. But, aside from the specialists, the economics profession more broadly has been slow to realise this and factor it into policy responses.

Australia has an extremely concentrated economy, Sims says. We have one dominant rail freight company operating on the east coast, one dominant airline with two-thirds of the market, two beer companies, two ice-cream sellers and two ticketing companies, all with a 90 per cent share of their markets.

We have two supermarkets with a combined market share of about 70 per cent. We have three dominant energy retailers and three dominant telecommunications companies. We have four major banks, with a 75 per cent share of the home mortgage market.

This is much greater concentration than in other developed countries. And, as you’d expect, the profit margins of these companies generally exceed those of comparable companies overseas.

The centuries that businesses have spent pursuing economies of scale explain why we don’t have – and shouldn’t want - the huge number of small firms assumed by the economic theory burnt on the brains of most economists.

But, Sims argues, our relatively small population doesn’t justify the much greater concentration of our industries. For one thing, studies of Australian industry sectors show that the returns to scale stop increasing well before market shares are anything like as high as they are in Australia.

For another, Australia’s modest size doesn’t explain why our industries are getting ever more concentrated, so that our key players are less likely to be challenged by competitors.

And it’s not just our high concentration, it’s also that we see large asset-managing institutions with big shareholdings in most of the firms dominating an industry. Thus, asset managers have an interest in keeping the whole industry’s profits high by limiting price competition between the companies.

One study, of 70,000 firms in 134 countries, found that the average prices charged by our listed companies were 40 per cent above the companies’ marginal cost of production in 1980, and about the same in the late 1990s. But by the early 2000s, average prices were 40 per cent above marginal cost. By 2010, they’d risen to 50 per cent above, and by 2016 it was nearly 60 per cent.

Analysis by federal Treasury has found that our companies’ markups increased over the 13 years to 2017.

The evidence in Australia and overseas is that in concentrated industries we see less dynamism, lower investment and lower productivity, Sims says. Our productivity performance has been very poor at a time when our focus on pro-competition public policy appears to have been lost.

It’s not hard to believe that the latter explains the former. “We run harder when competing versus when we run alone,” Sims says.

Our Treasury’s research also shows that firms in concentrated markets are further from the productivity frontier as there’s less incentive to keep up.

And market concentration also has implications for wage levels. Where labour mobility – the ease with which people move between employers – is reduced, wage levels are lower.

But high industry concentration means fewer firms that workers can move to, bringing relevant skills, and fewer new firms entering the industry. Less competition for workers means lower wages.

“Non-compete clauses” make the problem worse. Recent Australian studies have shown that more than one in five employees are prevented from working for competitors under such contract terms, often even in fairly low-skilled jobs.

Another finding is that the benefits of improved productivity are less shared with workers in concentrated industries. The share of productivity gains going to workers has declined by 25 per cent in the last 15 years, Sims says.

So next time some business person, politician, Reserve Bank governor or other economists tells you higher productivity automatically increases everyone’s wage, don’t fall for it. Used to be true; isn’t any more.

All this says that if the Albanese government is fair dinkum about getting inflation down and productivity and wages up, it will at least ban non-compete clauses and tighten up our merger laws.

Less competition reduces the power of interest rates to cut inflation

The ground has been shifting under the feet of the world’s central bankers, including our own Dr Philip Lowe, the outgoing chief of the RBA. This has weakened the power of higher interest rates to get inflation down.

Like all economists, central bankers believe their theory – their “model” – gives them great understanding of how the economy works and what they have to do to keep inflation low and employment high.

They know, for instance, that inflation – rising prices – occurs when the demand for goods and services exceeds the economy’s ability to supply those goods and services. So they can use an increase in interest rates to discourage businesses and households from spending so much.

This will reduce the demand for goods and services, bringing it into alignment with supply and so stop it causing prices to rise so quickly. It will also slow the rate at which the economy’s growing, of course.

But, with a bit of care, they won’t need to push interest rates so high the economy goes into “recession”, when demand (spending) becomes so weak that the economy gets smaller, causing some businesses to go bust and many workers to lose their jobs.

This theorising has worked reasonably well for many years, leading central bankers to be confident they know how to fix the present surge in inflation.

But the economy keeps changing, particularly as we keep using advances in technology to improve the range of goods and services we produce, and the way we produce them.

One consequence of our businesses’ unending pursuit of labour-saving technology – more of the work being done by machines and less by humans – has not been fewer jobs, but bigger factories and businesses.

As in all the rich economies, many industries are now dominated by just a few huge companies. In our case, we’re down to just four big banks, three big power companies, three big phone companies, two airlines and two supermarket chains. And that’s before you get the handful of giants dominating the rich world’s internet hardware, software and platforms.

Trouble is, when just a few firms dominate an industry, they gain “market power” – the power to hold their prices well above their costs; to increase their “markup”, as economists say.

The size of markups is a measure of the degree of competition in an industry. When competition between firms is strong, markups are low. When competition is weak, markups are high.

There is much empirical evidence that industries in the rich countries have become more concentrated over time, and markups have risen. And, as I’ve written before, Australia’s no exception to this trend.

In economics, “monopoly” means just one seller. “Monopsony” means just one buyer. So, when a firm has a degree of monopoly power, it can overcharge its customers. When a firm has a degree of monopsony power – when workers don’t have many employers to pick from – it can underpay its workers.

Researchers have found much evidence of labour-market power. And again, I’ve written before about the evidence this, too, is happening in Australia.

But this week, at the annual Australian Conference of Economists, federal Competition Minister Andrew Leigh, himself a former economics professor, drew attention to two recent International Monetary Fund research papers suggesting that a lack of competition is reducing the effectiveness of monetary policy – the manipulation of interest rates – in influencing inflation.

The first paper, by Romain Duval and colleagues, uses American data and data from 14 advanced economies to find that, compared with low-markup firms, high-markup firms are less likely to respond to changes in interest rates. The level of their sales changes less, as do their decisions about future investment in production capacity.

So, fat markups mean companies are less likely to change their behaviour. They’re not likely to cut their investment spending, for example.

This means more of the pressure to respond to higher rates will fall on households with big mortgages, but also on firms with low markups.

The second paper, by Anastasia Burya and colleagues, uses online job ads from across the United States to find that in regions where firms have a lot of labour-market power – that is, where workers don’t have much choice of where to work – those firms can hire workers without having to offer higher wages to attract the people they need.

This is the opposite of what standard theory predicts. It’s bad news for workers, who could have expected strong demand for labour to push up wages.

But another way to look at it is that, where big firms have labour-market power, there’s little relationship between employment and the change in wages. If so, conventional calculations of the “non-accelerating-inflation rate of unemployment” – the lowest point to which unemployment can fall without causing wages to take off – will give wrong results, encouraging central banks to keep unemployment higher than it needs to be.

And at times when price inflation is too high, unemployment will have to rise by more than you’d expect to get the rate of inflation back down to where you want it. How do you bring about a bigger rise in unemployment? By increasing interest rates more than you expected you’d have to.

So, whether it’s inadequate competition in the markets for particular products, or inadequate competition in the market for workers’ labour, lack of competition makes monetary policy – moving interest rates – less effective than central bankers have assumed it to be.

The model of how markets work that central bankers (and most other economists) rely on assumes that the competition between firms – including the competition for workers – is intense.

In the real world, however, markets have increasingly become dominated by just a few huge firms, which has given them the power to keep prices higher than they should be, and wages lower than they should be.

Leigh, Minister for Competition, gets the last word: “If you care about central banks being able to do their jobs, then you should care about a competitive and dynamic economy.”

Ever wondered why your wages aren't rising?

It’s dawning on people that when the competition between businesses isn’t strong, firms can raise their prices by more than the increase in their costs, and so fatten their profit margins. What’s yet to dawn is that weak competition also allows businesses to pay their workers less than they should.

In standard economic theory, it’s the intense competition between firms that prevents them from overcharging for their products and earning more than a “normal” profit.

Normal profit gives the owners of the firm just sufficient return on the capital they’ve invested to stop them leaving the industry and trying their luck elsewhere.

The theory assumes the industry has numerous firms, each one too small to influence the market price. In today’s world, however, many markets are dominated by just two, three or four huge firms.

These firms are big enough to influence the market price, especially when it’s so easy for them to collude tacitly with their rivals.

We see the four big banks doing this every time interest rates are raised. They have an unspoken agreement not to compete on price.

EverI say they have “pricing power”, but many economists say they have “monopoly power”. How can a handful of firms have monopoly power? Because economists don’t use that term literally. On a scale of one to 1000 firms, we’re right down the monopoly end.

Dr Andrew Leigh, the Assistant Minister for Competition, and a former economics professor, has been giving a series of speeches about recent empirical studies on how competitive our markets are.

In one, he quoted the findings of Jonathan Hambur, a researcher who pivots between Treasury and the Reserve Bank, that Australian firms’ “mark-ups” – the gap between their cost of production and their selling price – have been rising steadily.

But in a further speech this month, Leigh turned the focus from what “market concentration” (among a few massive companies) means for the industry’s customers, to what it means for its employees.

So, in econospeak, we’re moving from monopoly to “monopsony”. Huh? Taken literally, monopoly means a market in which there’s a single seller meeting the demand for the product. Monopsony means there’s a single buyer from the people supplying the inputs to production. Workers supply the firm with the labour it needs.

The term was introduced by Joan Robinson, a colleague of Keynes at Cambridge, who was among the first to question the standard theory of how markets work. She was 30 in 1933 when she published her dissenting view that truly competitive markets were rare.

She argued that monopsony was endemic in the labour market and employers were using it to keep wages low. If there are few employers competing for workers, those workers have fewer “outside options” (to move to another firm offering higher pay or better conditions).

This limits workers’ bargaining power and gives employers the power to keep wages lower.

At the time, few economists took much interest. But in recent years there’s been a growing focus on market power by academic economists.

For instance, monopsony was cited in a US Supreme Court ruling against Apple in 2019. A report by Democrats in the US House of Representatives accused Amazon of using monopsony power in its warehouses to depress wages in local markets.

Evidence from the US, Britain and Europe has demonstrated that increases in labour market concentration – fewer employers to work for – are associated with lower wages.

Leigh says economists have long known that people in cities tend to earn more than those in regional areas. His own research found that when someone moves from a rural area to a major Australian city, their annual income rises by 8 per cent.

“The economics of monopsony suggests that an important part of the urban wage premium can be explained by greater employer competition in denser labour markets,” Leigh says.

Leigh reminds us that Australia’s average full-time wage ($1808 a week last November) was only $18 a week higher than it was 10 years ago, after allowing for inflation. Many things would explain this pathetic improvement, but one factor could be employers’ monopsony.

We know that the rate at which people move between employers has fallen. But over a person’s working life, the biggest average wage gains come when people switch employers. And when some people leave, the bargaining power of those who stay is increased.

This decline in people moving could be caused by increased employer monopsony. Hambur has done a study of employment concentration between 2005 and 2016.

He found that, within industries where concentration rose, growth in real wages over the decade was significantly lower.

When a firm has a large share of the industry’s employment, the gap between the value of the work a worker does, and the wage they’re paid in return, tends to grow.

He found that employment in regions close to major cities is twice as concentrated as in the cities. In remote areas it’s three times.

Read this carefully: Hambur found that labour markets had not become more concentrated over the decade. But at every degree of concentration, its negative impact on wages had more than doubled.

So, employers’ market power could well be a factor helping to explain the virtual absence of real wage growth over a decade. Hambur finds that the greater impact of employer concentration may have caused wage growth between 2011 and 2015 to be 1 per cent lower than otherwise.

This would help explain why not all the (weak) growth in the productivity of labour during the period was passed through to real wages – as conventional economists and business people always assure us it will be. Weak competition allowed employers to keep a lot of it back for themselves.

Part of the competitive process is new firms entering the industry. New firms usually poach staff away from the existing firms. But we know the rate of new entry has declined.
