04 — Policy Simulation Lab

If you ran the country, what would you change?

Adjust eight policy levers and watch four indicators of mobility, equality, opportunity, and wellbeing respond. This is an educational model — not a real prediction.

Educational simulation. The relationships below are simplified, drawn from cross-country research intuition (OECD, Chetty et al.). Real economies are far more complex. Use this to build intuition, not to make policy.

Policy Levers

4.5% GDP

Public investment in schools, teachers, and learning materials. Higher spending tends to improve equal access to quality education — a core driver of long-run mobility.

2% GDP8% GDP
6.0% GDP

Public health spending per capita. Health shocks are a leading cause of downward mobility; universal coverage cushions families against them.

2% GDP12% GDP
40/100

How steeply tax rates rise with income. More progressive systems redistribute from top to bottom, compressing the income distribution.

0/100100/100
35/100

Targeted financial aid for low-income students. Reduces the income-graduation gap and widens the pipeline to higher education.

0/100100/100
45/100

A wage floor for the lowest-paid workers. Raises bottom incomes but, set too high, may reduce low-skill employment in some models.

0/100100/100
30/100

Subsidised housing and rental assistance. Housing affordability determines whether families can live in opportunity-rich neighbourhoods.

0/100100/100
35/100

Job training, placement services, and wage subsidies. Helps displaced and young workers re-enter the labour market.

0/100100/100
30/100

Subsidised childcare and pre-primary education. Early investment compounds over a lifetime and is among the highest-return mobility policies.

Social Mobility

How easily children can move up the income ladder relative to their parents.

Income Equality

Equality of Opportunity

Whether a child’s starting point — not their talent — determines their outcomes.

The economics behind the sliders

Why each lever moves mobility

A short, plain-language explanation of the mechanism behind every policy in the simulator.

Education Spending

Public investment in schools, teachers, and learning materials. Higher spending tends to improve equal access to quality education — a core driver of long-run mobility.

Healthcare Investment

Public health spending per capita. Health shocks are a leading cause of downward mobility; universal coverage cushions families against them.

Tax Progressivity

How steeply tax rates rise with income. More progressive systems redistribute from top to bottom, compressing the income distribution.

Need-based Scholarships

Targeted financial aid for low-income students. Reduces the income-graduation gap and widens the pipeline to higher education.

Minimum Wage

A wage floor for the lowest-paid workers. Raises bottom incomes but, set too high, may reduce low-skill employment in some models.

Housing Support

Subsidised housing and rental assistance. Housing affordability determines whether families can live in opportunity-rich neighbourhoods.

Active Employment Programs

Job training, placement services, and wage subsidies. Helps displaced and young workers re-enter the labour market.

Childcare & Early Years

Subsidised childcare and pre-primary education. Early investment compounds over a lifetime and is among the highest-return mobility policies.
