Economic objectives and the role of government Study Guide

Supply-side policies are government policies aimed at increasing the productive capacity of an economy. Unlike demand-side policies that focus on stimulating aggregate demand, supply-side policies seek to improve the supply side of the economy by making markets work more efficiently and encouraging investment, innovation, and competition. The ultimate goal is to shift the long-run aggregate supply curve to the right, leading to sustained economic growth, lower inflation, and reduced unemployment. These policies can take various forms, including deregulation to reduce barriers to entry and competition, privatisation of state-owned enterprises to improve efficiency, tax reforms to incentivise work and investment, and investments in education and training to boost human capital and productivity. Additionally, subsidies for research and development encourage innovation, and improvements in infrastructure (e.g., transport, communication) enhance the overall efficiency of production and distribution. While often associated with long-term benefits, supply-side policies can take time to implement and for their effects to be fully realised. They may also face political opposition due to initial costs, potential inequities, or disruption to existing industries. Evaluating their effectiveness requires considering both their short-term impacts and their long-term contributions to economic stability and growth.

Low unemployment is a key macroeconomic objective for most governments. It refers to a situation where a very high proportion of the available workforce is employed, or actively seeking and finding employment. While 'zero unemployment' is practically impossible due to frictional and structural unemployment, a low unemployment rate often signifies a healthy and growing economy. When unemployment is low, more people are earning incomes, leading to higher aggregate demand for goods and services. This increased demand stimulates businesses to produce more, invest, and potentially hire even more workers, creating a positive cycle of economic growth. Conversely, high unemployment leads to lower consumer spending, reduced business confidence, and a waste of human capital, which can drag down economic growth. Governments usually aim for an unemployment rate that is close to the natural rate of unemployment, which accounts for the unavoidable types of unemployment like people temporarily between jobs or those whose skills are no longer in demand. Achieving low unemployment can have several benefits, including higher tax revenues for the government, lower welfare costs, and improved social stability. However, persistently very low unemployment can sometimes lead to inflationary pressures as employers compete for scarce labour, driving up wages and, consequently, prices.
