Evidence

Evidence, contribution settings and careful implementation

Effective inclusionary housing policy depends on evidence, appropriate contribution settings and careful implementation. The MIZ initiative brings together Australian and international research, economic modelling and practical experience.

Quantifying the impact of a coordinated national framework

To support evidence-based policy, independent economic modelling was commissioned to quantify the impact of a coordinated, nationally consistent MIZ framework — examining MIZ's contribution to affordable housing supply, its effect on the development sector, and the timeframe for project viability to stabilise. The modelling was independently funded by Steering Committee members and has undergone a two-stage peer review, incorporating feedback from major developers, peak bodies and academic experts.
