This business economics assignment delves into various macroeconomic concepts, starting with an analysis of the Aggregate Demand-Aggregate Supply (AD-AS) model and the effects of fiscal policies such as changes in personal income tax, worker skill levels, and net exports. It examines how these factors shift the AD and AS curves, influencing price levels and output. The assignment further explores the limitations of fiscal policies in achieving specific GDP levels, the inevitability of frictional unemployment, and the government's concern regarding structural unemployment. Inflation is discussed through demand-pull and cost-push perspectives, highlighting their causes and differing impacts on output. The assignment contrasts Keynesian and Monetarist views on the sensitivity of price levels to aggregate demand and concludes with an analysis of the foreign exchange market, detailing the demand and supply of Australian dollars and the impact of shifts in these curves on the currency's value.
