ROSS GITTINS. Hey pollies: weak wage growth won’t fix itself. (SMH 4.2.2019)

Sorry, that possible explanation gets harder to believe as each quarter passes without any sign of nominal wage growth moving ahead of weak inflation, so as to give employees their rightful share of the improvement we’ve achieved in the productivity of their labour.

(And thus – ScoMo please note – giving the boost to real household disposable income, then consumer spending and then business investment spending, that has always been the greatest single contributor to “delivering a strong economy”.)

No, as years pass without the cycle restoring real wage growth, it becomes easier to believe the problem arises from some deeper issue with the structure of the economy.

The most popular structural explanation – best espoused by Professor Joe Isaac, an eminent labour economist – is that the “reform” of wage fixing went too far in shifting the balance of industrial bargaining power in favour of employers.

But another noted labour economist, former top econocrat Dr Mike Keating, has his doubts. He says he has no great objection to Isaac’s wage-fixing reforms, but doubts they’ll get wages moving because the structural problem is much deeper.

As argued in detail in his book with Professor Stephen Bell, Fair Share, and many articles and blogs, Keating sees our wages problem in the much broader context of the malaise of “secular stagnation” that’s been gripping the US and other advanced economies for at least a decade.

Keating reminds us that wage growth has been weak in most of the advanced economies for several decades, accompanied by rising inequality.

The distribution of earnings (that is, wages, rather than income from all sources) has become more unequal, Keating argues, mainly because of technological change and, to a lesser extent, globalisation.

Technological change has been “skill-biased”, with strong growth in high-skilled employment, and reasonable growth in unskilled jobs, but a decline in middle-level jobs, where routine jobs are being done by computers.

The result is a change in the structure of employment, one which increases earnings inequality. If so, it’s not a problem that could be fixed by higher wage-rates.

Keating says we’ve been slow in Australia to see what’s increasingly been realised overseas and by the international economic agencies: income inequality is bad for economic growth (mainly because the high-paid save rather than spend a higher proportion of their incomes).

But Keating’s more fundamental policy response to the problem of technology-driven weak wage growth and increased inequality is enhanced education and training, to help workers adjust to the challenges posed by new technologies, as well as spur the adoption of those technologies.

He’d give priority to early childhood learning and life-long learning through the TAFE system. He’s happy to note this would require us to pay more tax rather than less – another thought the pollies don’t want us thinking about right now.
