Supply side economics - April 2019

Supply-side policies are mainly micro-economic policies aimed at making markets and industries operate more efficiently and contribute to a faster underlying-rate of growth of real national output.


 

• Successful policies have the effect of shifting the LRAS curve to the right leading to a rise in potential output
• Most governments believe that improved supply-side performance is the key to achieving sustained growth without causing a rise in inflation.
• Supply-side reform on its own is not enough to achieve this growth. There must also be a high enough level of AD so that the productive capacity of an economy is actually brought into play.
• Supply-side policies can be implemented by the public or the private sector

Supply-side objectives

Key concepts to focus on are incentives, enterprise, technology, mobility, flexibility and efficiency.

• 1.Improve incentives to look for work and invest in people’s skills
• 2.Increase labour and capital productivity
• 3.Increase occupational and geographical mobility of labour to help reduce the rate of unemployment
• 4.Increase investment and research and development spending
• 5.Promoting more competition and stimulate a faster pace of invention and innovation to improve competitiveness
• 6.Provide a platform for sustained non-inflationary growth
• 7.Encourage the start-up and expansion of new businesses / enterprises especially those with export potential
• 8.Improve the trend rate of growth of real GDP
