IB Economics explores how societies allocate scarce resources to meet needs and wants, combining theory with real-world applications. The course develops analytical, quantitative, and evaluative skills while encouraging students to engage with contemporary global issues such as inequality, sustainability, and development. Standard Level (SL) students cover the four main sections of microeconomics, macroeconomics, international economics, and development economics. Higher Level (HL) students study the same topics in greater depth, with added emphasis on quantitative methods, advanced theory of the firm, macroeconomic models, and global trade analysis. The course equips students to understand economic decision-making, evaluate policy choices, and critically analyse their impact on individuals, firms, and nations.
