Productivity Assumptions Spark Debate Over Australian Economy's Future

The Australian economy's future has been laid out in the latest Intergenerational Report, which contains various economic projections and forecasts.

One of these figures that received significant attention was the assumption for productivity growth at 1.2% per year over the next four decades. This number is relatively low compared to previous decades and does not take into account the potential benefits of artificial intelligence (AI).

Economists have criticized both Treasury's estimate and the Reserve Bank of Australia's (RBA) assumptions for workforce participation and full employment, which differ from Treasury's projections.

HSBC chief economist Paul Bloxham described Treasury's assumption as 'unrealistically optimistic', citing issues with housing supply, energy costs, and infrastructure. On the other hand, Westpac's Luci Ellis argued that the RBA's forecasts might be too pessimistic, implying a repeat of factors that dragged down productivity outcomes in recent years.

The RBA's governor Michele Bullock believes the jobless rate needs to be between 4.5% and 5% to ease inflationary pressure, which is at odds with Treasury's estimate of a stable-inflation unemployment rate at around 4.25%. The current unemployment rate is 4.6%, according to recent data from the Australian Bureau of Statistics.

The RBA has hinted that it may focus on getting inflation back to target soon rather than pursuing full employment, given rising inflation and global economic developments.
