The warm-up for next month’s three-day economic roundtable has begun, and this week we’ll start hearing from worthies who know exactly what we should do to improve our productivity. What’s more, they have the modelling to prove it.

Did you see last week’s headline that “Productivity boost would make workers $14,000 richer”? It was attached to the news that this week Productivity Commission boss Danielle Wood will release a report recommending the government overhaul company tax, speed up planning approvals for infrastructure projects and embrace artificial intelligence.

And doing this would lead to Australia’s full-time workers being $14,000 a year better off within a decade, would it? Well, no. That’s not what she said. It was that if our productivity performance could return to its long-term average, then that would translate into every full-time worker being $14,000 a year better off by 2035.

So, there was no actual link between what she wanted us to do and this mere calculation of what a return to the higher rate of productivity improvement in our past would do to our pay cheques in the present.

But even this simple calculation assumes that, should a return to a higher annual rate of improvement in productivity come about, the workers would get their fair share of the proceeds.

My point is, we’re about to hear many worthies proposing we do more of this or more of that particular thing because it will improve the economy’s “productivity” – its ability to turn the same quantity of labour, capital equipment and raw materials into a greater........
