Unit 2: Macroeconomic Performance and Policy introduces the key measures of economic performance and the main objectives and instruments of economic policy in an international context. Students will learn how to use a basic AD/AS model to analyse changes in real output and the price level. Students will look at when demand and/or supply-side policies may be appropriate ways of improving an economy’s performance; consider these policies in an historical context; predict the possible impact of such policies and recognise the assumptions involved. Students should understand different approaches that may be used by policymakers to address macroeconomic problems and to identify criteria for success.
