Home / Models and tools
Overview

The lab develops integrated modelling tools to support rigorous research, policy engagement, advanced training, and reproducible quantitative analysis.

The lab's models are designed to bring together behavioural detail, institutional realism, and macroeconomic discipline. They are used to evaluate how fiscal reforms affect households, work incentives, savings, inequality, and long-run welfare.

Rather than focusing on a single question in isolation, the model suite allows policy analysis across multiple domains including taxation, retirement systems, social insurance, and health-related risk.

Researchers

Tools are built for researchers who need transparent and extensible structural frameworks.

Policy users

Applied questions can be framed in terms of distributional impact, welfare trade-offs, and fiscal sustainability.

Training

The model suite is also used as part of the lab's methods and capacity-building program.

Flagship frameworks

Core models

Each model speaks to a different dimension of macro public finance while sharing a common focus on heterogeneity and policy evaluation.

Microsimulation

Tax Simulator Australia

A structural lifecycle microsimulation model of Australian households for analysing income tax reform, means-tested transfers, and social insurance.

OLG framework

Stochastic OLG model with endogenous health

A model used to study health capital, insurance design, spending, and wealth accumulation over the lifecycle within general equilibrium.

Structural model

Earnings dynamics and inequality

A framework for studying earnings risk, distributional change, and non-Gaussian shocks using Australian administrative tax records.

Policy tool

Pension and retirement financing

A quantitative framework for pension reform, superannuation design, retirement savings, and the fiscal effects of ageing economies.

Capabilities

What the models are designed to do

The value of the model suite lies not only in the code itself, but in the range of empirical and policy tasks it can support.

Computation

Frameworks are solved with value function methods, policy iteration, and computational workflows suited to large-scale quantitative analysis.

Calibration

Models are disciplined using lifecycle patterns, tax records, household surveys, and other data sources relevant to the policy environment.

Policy analysis

The frameworks support reform evaluation across taxation, transfers, pensions, and health-related policy with distributional and welfare metrics.

Use cases

Researchers, policymakers, and students

The models support different users, from academic collaborators to training participants and policy audiences seeking quantitative counterfactuals.

Research

Academic collaboration

Researchers can use the model environment to extend existing work, test alternative assumptions, or frame new questions in fiscal policy.

Policy

Applied policy design

Government and policy users can engage with the models as part of discussions on tax reform, transfers, pensions, and long-run fiscal trade-offs.

Training

Methods instruction

The same frameworks also underpin workshops and training on lifecycle models, calibration, and quantitative policy evaluation.
