The Bachelor of Science in Economics at Caltech, offered by the Division of the Humanities and Social Sciences, is a four-year undergraduate program focused on modern, quantitative economic principles seldom available at the undergraduate level. The curriculum covers core economic theory, data analysis, applied microeconomics, and macroeconomics/growth, supported by additional electives in political science and mathematics. This flexible program encourages interdisciplinary integration with engineering, math, or science, and prepares students for both advanced graduate study and professional careers in economics, law, business, and government. Students develop proficiency in modeling economic institutions, analyzing data to test theories and predict outcomes, and acquire a broad understanding of economic growth, crises, strategic behavior, and the role of technology and policy in economics.
