Supply-side policy is action taken by the government to increase the economy’s productive potential by improving the efficiency and flexibility of markets
These policies focus on increasing total (aggregate) supply in the long run, encouraging economic growth without creating inflationary pressure

Macroeconomic aim	How supply-side policy can help achieve it
Economic growth	Increases productive capacity, allowing more goods and services to be produced without inflation
Low inflation	By increasing total (aggregate) supply, growth can occur without upward pressure on prices
Low unemployment	Improves workers’ skills and increases job opportunities through labour market flexibility
Healthy balance of payments	Improves competitiveness in global markets through higher productivity and innovation
Fair income distribution	Well-designed policies (e.g. education access) can reduce inequality by improving opportunities
Sustainability	Investment in green infrastructure and technology encourages long-term, environmentally friendly growth

They increase the rate of growth of an economy
They reduce inflation
They often reduce unemployment
They often increase the value of net exports as an increase in total supply usually results in lower prices, leading to greater exports

The distribution of income worsens as labour market reforms and wage policies lower workers' wages
They are expensive to implement
There are significant time lags between government expenditure and seeing the benefits
- E.g. education and training often take a long time to have a measurable positive impact
Due to the long-term nature, changes in government often result in changes to budgets and scope of projects
Vested interests can result in less effective outcomes
- E.g. There are many examples of privatisation occurring in such a way that the government's preferred bidders obtained an asset at a knockdown price

Supply-side policies can help achieve macroeconomic aims
