🎁 Subsidies
Definition: A subsidy shifts the supply curve RIGHT (or downward by the amount of the subsidy).
Effect on the market
- Supply shifts right/down → equilibrium price FALLS, quantity RISES
- Consumers pay a LOWER price
- Producers receive a HIGHER effective price (market price + subsidy per unit)
- The government pays the total cost: subsidy per unit × quantity
Subsidies are the opposite of taxes in every way: taxes shift supply left and raise prices; subsidies shift supply right and lower prices.
📊 Who Gets the Benefit?
Just like taxes, the benefit of a subsidy is shared between consumers and producers — and the split depends on elasticity.
- Inelastic demand → consumers get LESS of the benefit (price does not fall much)
- Elastic demand → consumers get MORE of the benefit (price falls significantly)
- The more INELASTIC side gets LESS of the subsidy benefit
- This mirrors the tax incidence rule — just in reverse
Why governments use subsidies
- Make essential goods affordable (food, education, healthcare)
- Correct positive externalities (vaccines, renewable energy — see Topic 2.8)
- Support domestic producers (agriculture, infant industries)
- Encourage merit goods (goods that society believes are under-consumed)

⚖️ Evaluating Subsidies
Advantages
- Lower prices for consumers, especially on essential goods
- Higher output and employment in subsidised industries
- Can correct market failure (increase production of merit goods/positive externalities)
- Can protect strategic or infant industries
Disadvantages
- Opportunity cost — government money could be spent on something else (schools, hospitals)
- Market distortion — keeps inefficient producers in business
- Overproduction — can lead to surpluses (e.g. EU butter mountains)
- Difficult to remove — producers become dependent on subsidies
- May not reach intended recipients — benefits might go to producers rather than consumers
In evaluation, always consider the OPPORTUNITY COST of subsidies. The money has to come from somewhere — higher taxes, less spending on other services, or more government borrowing.
