This assignment delves into key microeconomic concepts, beginning with an analysis of dollar valuation, distinguishing between nominal and real values, and examining the impact of inflation. It then differentiates between economic recessions and depressions, outlining their characteristics and the varying saving behaviors of individuals who have lived through different economic periods. The assignment continues by exploring supply and demand dynamics, calculating equilibrium prices and quantities in a closed economy and subsequently analyzing the effects of opening up to international trade and the application of tariffs. Finally, the assignment addresses different types of unemployment, including natural, cyclical, frictional, and structural unemployment, and discusses key trends in the Australian labor market, such as changes in employment and unemployment rates. The analysis is supported by relevant economic theories and practical examples, making it a comprehensive study of microeconomic principles.
