Government spending doesn't just fund services — it directly adds to total economic demand. Every dollar spent becomes someone's income, every tax dollar taken shrinks their spending power. Adjust the budget levers below to see aggregate demand shift in real time.
When government spending increases, the G component of AD rises directly — every dollar flows into the circular flow as income for contractors, employees, or suppliers. This immediate injection boosts total demand without any time lag. The multiplier effect then amplifies the impact as recipients spend their new income, generating further rounds of consumption. This is why fiscal stimulus through spending is considered the most direct demand-side lever available to policymakers.
