Interdepartmental Major in Economics and Mathematics B.A.

Economics models the production and consumption of goods and services, and one of the natural languages of economics is mathematics. Businesses, industries, and government agencies actively seek graduates with analytical training in mathematics, technical training, and knowledge of core economic and financial principles.

The Interdepartmental Major in Economics and Mathematics involves coursework in both the Department of Economics and the Department of Mathematics, each of which is part of the Indiana University College of Arts and Sciences.

When pursuing the Interdepartmental Major in Economics and Mathematics you work with economics faculty and mathematics faculty whose expertise spans economic analysis and policy and the frontiers of mathematical understanding respectively. Both departments are highly ranked nationally, offering comprehensive coverage of the major areas in modern economics and mathematics.

The Interdepartmental Major in Economics and Mathematics can prepare you for graduate work in a variety of fields, giving you the quantitative tools needed to measure economic indicators, make sense of big data, and analyze strategic interactions arising in economics, business, and international relations. The degree also prepares you for a possible career in the actuarial sciences.

Both the Department of Economics and the Department of Mathematics offer undergraduate minors for students majoring in other subjects.


Getting started

Interdepartmental majors in Economics and Mathematics take eight core classes, four in Economics and four in Mathematics. These focus on mathematical modeling, microeconomic theory, macroeconomic theory, and they establish a strong foundation in calculus.

Your starting point with the Economics and Mathematics interdepartmental major is introductory level micro and macroeconomics and the first two semesters of calculus:

  • MATH-M 211 Calculus I
  • ECON-E 251 or B251 Fundamentals of Economics I
  • MATH-M 212 Calculus II
  • ECON-E 252 or B252 Fundamentals of Economics II

These four courses provide you with the foundation to move on to the intermediate level in both Economics and Mathematics. You can satisfy the statistics requirement with either ECON-E 370 Statistical Analysis for Business and Economics or MATH-M 365 Introduction to Probability and Statistics.

Contact an economics or mathematics academic advisor to discuss your options and interests. 

Tracks and concentrations

By pursuing the Interdepartmental Major in Economics and Mathematics, you establish a strong foundation in microeconomic and macroeconomic theory, gaining the ability to model economic questions mathematically and to analyze and solve those models.

You can choose electives at the upper level in both economics and mathematics, concentrating on one particular area of mathematics. Because this is an interdepartmental major, there are no official tracks. Some of the specific areas in which you can take upper level courses are:

  • Financial and monetary economics
  • International and development economics
  • Analysis of economic data using statistical and computational methods
  • Economics of the public sector and labor markets
  • Economics of industry and strategic interaction
  • Calculus and analysis
  • Differential equations
  • Applied mathematics
  • Probability and statistics

The economics department offers a variety of undergraduate seminars (ECON-E 309, E 390, E 490) with topics and titles that vary across semesters. Seminar courses supplement courses in various areas.

In addition, high-achieving students can supplement concentration areas with independent research (ECON-X 398) and honors thesis research (ECON-E 499). Students with an interest in conducting original research should become familiar with the Indiana University Journal of Undergraduate Research (IUJUR)

Contact an economics or mathematics academic advisor to discuss your options and interests.

Upper level coursework

The Interdepartmental Major in Economics and Mathematics allows you to personalize the upper level curriculum through specialization in related courses. You should consult with an economics and a mathematics academic advisor, as well as faculty, to discuss the best courses to suit your interests in both areas.

Beyond the foundation courses you can choose upper level electives to explore in depth areas of interest in both subject areas. Through upper level electives you learn about an array of issues, such as:

  • Supply and control of money
  • Roles government entities play in the economy
  • Functioning of labor markets
  • Trade relations between countries
  • Obstacles to sustained growth in less developed nations
  • The functioning of financial asset markets

In mathematics you will choose upper level electives from these four areas:

  • Analysis
  • Differential Equations
  • Applied Mathematics
  • Probability and Statistics

Commonly pursued majors, minors and certificates

Your major represents about a third of your degree requirements. With the help of your academic advisor, you may be able to combine several areas of interest with additional majors, minors, or certificates.

There are over 90 areas of study in the College of Arts and Sciences, any of which you could potentially add as an additional major, minor, or certificate. Some examples of areas that can complement the Interdepartmental Major in Economics and Mathematics are:
