This economics tutorial project explores fundamental concepts in both microeconomics and macroeconomics. The assignment addresses six key questions, starting with the calculation of price elasticity of demand using the midpoint formula for petrol and air conditioners, and interpreting the implications of elastic and inelastic demand, including the incidence of tax. It then delves into the differences between accounting and economic profit, providing advice on which is a better parameter for a business owner, and analyzes the characteristics of a monopoly firm, discussing its demand curve, benefits, long-run profit scenarios, and consumer effects. The macroeconomics section covers calculating nominal and real GDP, examining the impact of various components on GDP growth, and discussing the role of a central bank in managing money supply. The project provides detailed calculations, explanations, and graphical illustrations to aid in understanding the core economic principles.
