Supply-side policies aim to improve the productive potential of an economy through various market-based and state intervention approaches. Market-led policies focus on making markets more competitive through deregulation and tax cuts, while state intervention aims to address market failures. The goals are to increase productivity, investment, skills, and competitiveness. This can generate higher long-run economic growth and living standards. However, supply-side policies face limitations such as long time lags and risks of unintended consequences from government intervention in markets. Evaluating their impact requires considering both supply and demand-side factors.
