Study Notes
The role of government in microeconomics involves using tools like indirect taxes and subsidies to influence markets and stakeholders. Indirect taxes are levied on goods and services, affecting consumer and producer behavior, while subsidies are financial aids to encourage production.
- Indirect Taxes — taxes on spending for goods and services, collected by producers and paid to the government.
Example: Sales taxes, excise taxes, and customs duties. - Ad Valorem Tax — a tax expressed as a percentage of the value of the purchase.
Example: 10% VAT on petrol. - Specific Tax — a fixed amount of tax per unit of good sold.
Example: $2 tax per gallon of petrol. - Subsidy — a payment from the government to firms to encourage production.
Example: Subsidies for renewable energy production. - Regressive Taxation — lower income earners pay a higher proportion of their income in tax.
Example: VAT affecting lower income earners more. - Progressive Taxation — higher income earners pay a larger proportion of their income in tax.
Example: Income tax with increasing rates. - Proportional Taxation — all income earners pay the same proportion of their income in tax.
Example: Flat tax rate of 15% for all income levels.
