Economists Critique Government's Optimistic Productivity Projections

This optimistic assumption forms the basis for projected growth in both the economy and living standards. The report predicts that Australia's economy will more than double in size in real terms over the next 40 years, with income per capita expected to increase by 55 percent. Chalmers cited the potential of the artificial intelligence (AI) revolution as a significant factor in this economic transformation.

However, under a more conservative forecast suggesting a productivity growth of 0.8 percent annually, which remains above the Reserve Bank's assumption of 0.7 percent, the average Australian's income could be $20,000 lower than the baseline projection of $149,500. This initial forecast from Treasury had relied on productivity returning to its long-term assumption of 1.2 percent, which was downgraded from 1.5 percent in 2022.

The decline in productivity, particularly noted across developed countries, is attributed to structural shifts toward a service-based economy, an aging population, and slower technological advancements. While Treasury is counting on AI and regulatory changes to boost productivity, there has been limited evidence to support this reliance.

HSBC chief economist Paul Bloxham expressed skepticism about the expectation that productivity would rebound quickly, particularly in light of recent declines. He remarked on Australia’s supply constraints, such as housing shortages and energy costs, suggesting that AI alone is unlikely to resolve these issues.

Independent economist Chris Richardson criticized the government's assumption, stating that the reliance on AI appears to be a superficial fix, masking deeper economic challenges.
