The course offerings of the Department are categorized as follows: Introductory Courses ECON 1: Introduction to Microeconomics ECON 2: Introduction to Macroeconomics ECON 10: Introduction to Micro and Macro Economics and its Applications (for Wharton students only. See also Advice for Wharton Students) See Advanced Placement Waivers for information on the Advanced Placement or International Baccalaureate exams and Credit for External Courses for what courses might be eligible to place out of ECON 1, ECON 2, and ECON 10. Courses Intended for Non-Majors These courses have two-digit numbers and have as prerequisites ECON 1 and/or ECON 2, or ECON 10. Some instructors expect students to know some basic calculus. Course Incompatibilites Note: The same course cannot be taken at both the lower level and the advanced (200) level. Thus, the following combinations of courses are incompatible: 30 and 231, 32 and 232, 33 and 233, 35 and 235, 36 and 234, 39 and 236. Intermediate-Level Courses These courses are numbered ECON 1xx and include ECON 101 (Microeconomic Theory); ECON 102 (Macroeconomic Theory); ECON 103 (Statistics for Economists); ECON 104 (Introduction to Econometrics). Mathematics Prerequisite: All intermediate-level courses require MATH 104 and MATH 114 or 115 as prerequisites. Students in their sophomore year or beyond must have at least a B+ in MATH 104 to take ECON 101 and MATH 114 or 115 concurrently. Students who have waived out of MATH 104 and MATH 114 or 115 may proceed to ECON 101 with permission from the Department. Students who have waived out of MATH 104 only must complete MATH 114 or 115 before enrolling in ECON 101. Further Prerequisites: ECON 101: requires ECON 1 and ECON 2. Wharton students who received a grade of at least A- in ECON 10 can use ECON 10 to satisfy the economics prerequisite. Wharton students who take ECON 10 instead of ECON 1 and ECON 2 and have received a grade lower than A- will not be permitted into ECON 101. The ECON 1, 2 prerequisite is waived for Networked and Social Systems Engineering (NETS). Wharton students can satisfy the ECON 101 prerequisite for ECON 102 and ECON 104 with BEPP 250 HONORS. The regular BEPP 250 course does not count as a substitute for ECON 101. ECON 102: requires ECON 1, ECON 2, and ECON 101. ECON 103: requires ECON 1 and ECON 2 ECON 104: requires ECON 1, ECON 2, ECON 101, and ECON 103 Advanced Courses These courses are numbered 2xx. Advanced economics courses require some or all of the intermediate-level 1xx courses as prerequisites. Moreover, these courses require two semesters of calculus (see Mathematics Prerequisite under Intermediate-Level Courses above.) In addition, the Department offers an Independent Study (ECON 199) and an Honors Thesis course (ECON 300). Wharton students can satisfy the ECON 101 prerequisite for ECON 102 and ECON 104 with BEPP 250 HONORS. The regular BEPP 250 course does not count as a substitute for ECON 101.
