Courses that provide a foundation for the study of business economics may be required in order to be accepted into a business economics major. Principles of Economics; Introductory Microeconomics and Macroeconomics; Probability and Statistics; Mathematics that are relevant to economists, such as Calculus; as well as Management courses on the Principles of Accounting and any required writing classes may fulfill these pre-major requirements.
A major in business economics may require ongoing coursework in intermediate-level economics that build on earlier classes; hence, intermediate microeconomics and macroeconomics, and applied econometrics courses may be appropriate. Some schools may stipulate taking seven additional economics courses, at least four of which must be upper-division classes.
Schools offer a wide array of elective courses to round out the required business economics coursework. While you will have latitude of choice, departments will sometimes have you select courses from a specific field or set of classes, such as those designated "Business Electives," which could include courses in Business Forecasting, the Economics of Risk and Uncertainty, Introduction to Financial Investments and Corporate Finance. Courses under "Management Electives" might include Behavioral Economics, Labor Economics and Human Resources, Managerial Economics and Corporate Governance. Alternately, they may list a group of courses and ask you to choose a set number of courses from each group.
Many business economics courses are available online, as well, for the casual studier or the harried full-time student. These courses may not self-describe themselves as "business economics" courses, but the topics will cover many of the topics that a business economics program might offer. Online courses will often have syllabi and handouts, as well as lecture notes, to supplement the readings and problem sets. Dozens of courses are offered by universities such as MIT and the Open University, and may cover topics such as Competitive Decision-Making, Advanced Managerial Communication and Global Strategy.
