The purpose of this course is to prepare for the study of undergraduate-level introductory basic concepts of economics. This course aims to present economics as the basic workings of markets and the reasons they improve people’s lives. Economics is a two-semester course presenting the core principles of microeconomics and macroeconomics. In the first semester, we concentrated on microeconomics. Topics include demand and supply, consumer behavior, price elasticity, produce and cost, complete competition market, and imperfectly competitive market. In the second semester, we concentrate on Macroeconomics, the study of the economy as a whole. Topics include basic concepts in measuring a nation’s production and income, banking system, money creation and monetary policy, fiscal policy, equilibrium income decision, aggregate demand and supply, inflation and the business cycle, unemployment and economic growth, and international finance.
