In 2016, this subject replaced by 200926 - Macroeconomic Measures and Models. Macroeconomic Issues provides tools to assess competing explanations, predictions and policy recommendations regarding the macroeconomy. Building on the introductory concepts, measures and simple theories, this subject develops a comprehensive model for identifying and quantifying the sources and mechanisms of macroeconomic change. A systematic modelling approach reveals whether differences are rooted in assumptions or empirical claims. We focus on Australia, but consider controversies relating to the USA, Asia and Europe, given their impact on global conditions and the lessons they offer for Australia. Topics include productivity and growth, the determinants of unemployment and inflation, the role of exchange rates in adjustment, and monetary and fiscal policy design.
