These linked modules are the intermediate macroeconomics modules. They consider theories of behaviour of the aggregate economy beyond the introductory Principles of Economics module. The main purpose of these modules is to provide richer theoretical foundations for the study of macroeconomics in the short- and long-run and to equip students with the basic toolbox of macroeconomic analysis. The topics covered include: IS/LM and AD/AS in closed and open economies, inflation, unemployment, monetary policy, growth, fiscal policy and theories of consumption and investment. Issues arising from modern behavioural macroeconomics are also discussed.
