Summary and Exam Tips for Supply side policy
Supply side policy is a subtopic of Government macroeconomic intervention (AS Level), which falls under the subject Economics in the Cambridge International A Levels curriculum.
Supply-side policies aim to enhance the long-run aggregate supply (LRAS) by increasing productivity and productive capacity. These policies focus on improving the efficiency of product and factor markets, which can involve either reducing or increasing government intervention. The primary objective is to shift the LRAS curve to the right, indicating an increase in the economy's productive capacity. Key tools include investment in education and training, which enhances workforce skills and productivity, and infrastructure development, which reduces production costs and facilitates market access. Technological improvement is also crucial, as it allows for increased output at lower costs. Other tools include tax cuts, trade union reforms, privatization, deregulation, and encouraging immigration. The impact of these policies can be seen in increased national income, real output, and employment, while also managing inflation. However, the effectiveness of these tools can vary, with challenges such as time, cost, and uneven distribution of benefits.
