This macroeconomics assignment, completed for ECON1007 at the University of South Australia, addresses key macroeconomic concepts. The assignment begins by analyzing the relationship between weak wage growth and short-term economic growth using the aggregate expenditure model, examining the impacts of consumption, investment, and net exports. It then explores the effects of cutting interest rates, considering factors like inflation, wage growth, business investment, and overall economic growth. The assignment also delves into the implications of an increasing part-time workforce, discussing unemployment rates and the natural rate of unemployment, including the long-run aggregate supply curve. Finally, it examines the consequences of the government misestimating the NAIRU and stimulating demand, leading to inflation. The document provides detailed explanations, diagrams, and references to support its analysis, offering a comprehensive understanding of macroeconomic principles.
