**The Registrar’s deadline to declare a secondary field in my.harvard for May 2026 and November 2026 graduates is March 18, 2026.** No secondary field may be added to the degree after the deadline; no exceptions will be made.

You must also connect with an [Ec concentration advisor](https://www.economics.harvard.edu/advising) to complete your Ec Secondary Field Form (see details below), either live during office hours or via email to the Ec advisor associated with your House. The deadline to complete this form for May 2026 and November 2026 graduates is May 1, 2026.

**Secondary Field submissions can only be approved once you are enrolled in and attending the last class that fulfills the secondary field requirements. In order to have your secondary field approved:**

1. **Declare your secondary on my.harvard.edu. Instructions** [**here**](https://harvard.service-now.com/ithelp?id=kb_article&sys_id=529e5ecadb6f4f04a914fff31d96190c)**.**
2. **Fill out a** [**Ec secondary field form**](https://www.economics.harvard.edu/sites/g/files/omnuum5991/files/2026-04/Secondary%20Field%20Form_v2_0.pdf)**.**
3. **Have your form approved by an** [**Ec concentration advisor**](/advising), either live during office hours or via email to the Ec advisor associated with your House. If you have questions about this form or the secondary field in economics, we encourage you to meet with an advisor during office hours.

## Requirements: 6 courses

1. **Economics 10A and 10B**: Principles of Economics. (see here for [information](/ec-10ab) on EC 10AB. SF students who skip EC 10A and/or EC 10B must replace each course with an additional economics elective.)
2. **One course** from:  
    --**Economics 1010A/1011A**: Microeconomic Theory  
    --**Economics 1010B/1011B**: Macroeconomic Theory  
    These courses teach the analytical tools used by economists. 1011AB assumes background in multivariate calculus; 1010AB assumes only single variable calculus. A minimum grade of B- is required. Students receiving a grade below B- should speak with a Concentration Advisor to discuss options.
3. **Three economics electives** from the Economics courses in [my.harvard.edu](https://my.harvard.edu/). See also [here](https://www.economics.harvard.edu/courses-tutorials-and-seminars).  
    --All Economics courses and cross-listed courses are eligible **except for** 910R, 970, 975AB, 985, 990, and graduate-level research seminars/workshops. Taking both 1010A/1011A and 1010B/1011B meets requirement 2 above and one of the courses in requirement 3.
