Supply-side policies aim to improve the productive potential of an economy through various market-led and state intervention approaches. Market-led policies focus on making markets more competitive through deregulation and tax cuts, while state intervention aims to overcome market failures. The objectives of supply-side policies include improving skills, productivity, investment, and competitiveness. Successful supply-side policies could achieve sustained low inflation growth and reduce unemployment. However, the effects of supply-side policies can take a long time to materialize and not all policies effectively pick winners. Evaluating their impact also requires considering demand-side conditions and issues like inequality and sustainability.
