Directors of undergraduate studies: Ebonya Washington (Economics), Rm. 36, 37 Hillhouse Ave., 432-9901; Andrew Neitzke (Mathematics), DL 425; associate director of undergraduate studies: Miki Havlickova (Mathematics), DL 446; Qazi Azam (registrar)
The Economics and Mathematics major is intended for students with a strong interest in both mathematics and economics and for students who may pursue a graduate degree in economics.
The major has prerequisites in both mathematics and economics: MATH 120; ECON 110 or 115; and ECON 111 or 116. With permission of the directors of undergraduate studies (DUSes), upper-level courses may be substituted for prerequisite courses. Upper-level courses substituted for prerequisites do not count toward the total of twelve term courses (beyond the introductory level in economics and mathematics) required for the major.
Requirements of the Major
A total of twelve term courses is required beyond the introductory level in economics and in mathematics: seven term courses in economics and five term courses in mathematics numbered above 200 (except MATH 470). These courses must include:
- One intermediate microeconomics course chosen from ECON 121 or 125, and one intermediate macroeconomics course chosen from ECON 122 or 126.
- A year of mathematical economics, ECON 351 and one of ECON 350, 417, or 433.
- Two courses in econometrics, ECON 135 and 136. With permission of the DUS in Economics, S&DS 241 and 242 may be taken instead of ECON 135, in which case they count as one economics course and not as mathematics courses. Neither S&DS 241 nor 242 can be counted toward the major in parallel to ECON 135.
- Students in the Class of 2025 and beyond must complete linear algebra (MATH 222 or 225 or 226) and real analysis (MATH 255 or 256). Students in the Class of 2024 and previous classes, may use MATH 300, 301, or 305 to fulfill the real analysis requirement (in place of MATH 255 or MATH 256). They may also use MATH 231 to fulfill the linear algebra requirement (in place of MATH 222 or 225 or 226).
A course must be listed with a MATH number to count toward the mathematics requirements—substitutions from other departments are not allowed.
Distinction in the Major To be considered for Distinction in the Major, students must meet minimum grade standards, as specified under "Honors" in The Undergraduate Curriculum, and submit a senior essay in Economics that earns a grade of A or A–. One-term essays may be written in either an Economics department senior seminar or in ECON 491. Two-term senior essays may be written in either an Economics senior seminar and ECON 492 or in ECON 491 and 492. (The paper must be written in a course or courses taken in the senior year.) For details see Economics. All courses beyond the introductory level in Mathematics and Economics are counted in the computation of grades for Distinction.
Credit/D/Fail Courses taken Credit/D/Fail may not be counted toward the requirements of the major.
Students interested in the major should consult both DUSes, and verify with each that their proposed program meets the relevant guidelines. Registration forms must be signed by both DUSes each term.
REQUIREMENTS OF THE MAJOR
Number of courses 12 term courses beyond prerequisites (incl senior req)
Distribution of courses 7 courses in econ and 5 in math
Substitution permitted S&DS 241 and 242 for ECON 135, with permission of Economics DUS; MATH 300 or 301 may be substituted for MATH 255 or MATH 256. MATH 231 may be used to fulfill the linear algebra algebra requirement, replacing MATH 222 or 225 or 226
