Supply-Side Policy Simulator

Supply-side policies are government policies designed to increase the productive capacity, productivity, efficiency, or competitiveness of an economy. Their main goal is usually to increase long-run aggregate supply.

Diagram shifts are slightly exaggerated for educational clarity. Not numerical forecasts. E₁ and E₂ are short-run equilibria. AD is held constant to isolate the supply effect; full long-run adjustment is not modeled.

Start with a policy

Choose one of the 14 policy cards. Change the time horizon to distinguish immediate effects from longer-term productive capacity.

MATCH THE POLICY TO THE PROBLEM

When should supply-side policies be used?

These policies mainly target longer-term improvements. They usually cannot quickly fix a recession caused by weak aggregate demand.

Low productivity growth

Education, training, technology, and infrastructure can raise output per worker and productive capacity.

High structural unemployment

Retraining, education, and labor mobility programs can help workers gain relevant skills and reach available jobs. More AD alone cannot fix every mismatch.

Cost-push inflation

Lower bottlenecks and improved productivity can reduce unit costs, increasing SRAS. These changes may take too long to offset an immediate oil-price shock.

Long-term economic stagnation

Skills, infrastructure, research, and business investment incentives can improve the economy’s long-term capacity to grow.
