On the University of Melbourne’s Parkville campus, there is a building that most guests pass by without giving it much thought. There isn’t a big announcement in front of it. Unlike particle physics or cancer research, the work inside doesn’t often make headlines. However, for more than 60 years, the Melbourne Institute of Applied Economic and Social Research has been discreetly generating some of Australia’s most important economic analysis; if anything, the gap between its public image and its real impact on the country’s governance is widening.
Professor Ronald Henderson founded the institute in 1962, and by the early 1970s, it had grown into a significant organization with about 40 employees. Smaller data sets, slower publishing cycles, and fewer opposing viewpoints characterized that era of economic study. The scope of what the institute currently oversees has altered, not the fundamental goal. Every year, the Household, Income and Labour Dynamics in Australia survey, or HILDA Survey, tracks almost 17,000 Australians and gathers comprehensive longitudinal data on income, work, housing, health, family formation, and wellbeing. It started operating in 2001.
No other study of a similar size and duration tracks the Australian population as HILDA does, and the collection of more than 24 years of continuous data on the same households provides researchers with something genuinely difficult to duplicate: the ability to see how lives actually change over time, rather than just how populations appear in any given snapshot.
The findings of the 2025 HILDA report, which was published in the first half of the year, had some impact in policy circles. Australia’s economic disparity is at its greatest level in over 20 years. The same households were tracked over time to see how their wealth and earnings changed in relation to one another. This is a direct finding rather than a projection or model output. In his commentary on the housing aspect of the statistics, Dr. Kyle Peyton succinctly described the structural issue: Australia’s retirement system was designed with the presumption that the majority of people would be homeowners by the time they retired.
For decades, public policy has prioritized increasing housing demand at the expense of supply, driving up prices and solidifying the kind of intergenerational wealth disparity that the system was never intended to create. He pointed out that superannuation will not be sufficient for the increasing number of younger Australians who are prevented from becoming homeowners. This has significant ramifications for pension policy, funding for aged care, and budgetary planning for the next thirty years.
Some of the institute’s conclusions are more focused but on a smaller scale. The average number of children desired by Australian men has dropped below two for the first time since HILDA started monitoring reproductive intentions in 2005, from 2.22 to 1.99 in 2023. The preferences of women have likewise decreased, from 2.35 to 2.09. Younger age groups saw the biggest declines. These are not abstract demographic numbers; rather, they represent a change in the way younger Australians envision their futures, and they have immediate ramifications for everything from long-term economic growth estimates to childcare policy and immigration settings.
The Melbourne Energy and Decarbonization Analysis Lab, or MEDAL, does research focused on the economics of the energy transition, figuring out what decarbonization actually costs and who suffers those costs. The institute’s work goes beyond HILDA. Professor Meredith Fowlie of UC Berkeley examined electricity pricing and what it means for an equitable energy future in the 2026 Downing Public Lecture, one of the institute’s premier annual events. Although this topic sounds technical, it has immediate practical implications for both household budgets and climate policy. Recognizing that the data processing requirements of large-scale longitudinal research are evolving at the same rate as the policy concerns the research is intended to address, a more recent unit, CALIBER, is developing AI-powered research infrastructure to support economic and business analysis.
What the Melbourne Institute excels at is something that is often overlooked when talking about economic research: it offers the empirical basis that reduces the abstract nature of policy discussions. The HILDA data provides the longitudinal evidence that separates a transient shock from a structural trend when politicians debate home affordability. The institute’s work contributes to the intellectual foundation of arguments around bracket creep, which is the process by which inflation subtly pulls middle-class taxpayers into higher tax bands without really increasing their purchasing power.
