New Econometrics Courses

We have two new econometric courses: Econ 117, Introduction to Data Analysis and Econometrics, and Econ 123, Intermediate Data Analysis and Econometrics. They are both offered in both spring and fall.

Econ 131 and Econ 132 are no longer offered. The new courses cover the topics of Econ 131 but with greater opportunities for students to see modern economic applications and to do hands on data analysis. Students who have taken Econ 131 will not receive major credit for Econ 117. They may take Econ 123.

Although we recommend that majors take two econometric courses, particularly if they are interested in writing a thesis, any one of Econ 117, 123, 131, 132 or 136 fulfills the econometric requirement for the major. Beginning with the class of 2021, two semesters of econometrics are required to write a senior thesis.


Given its strong econometrics content, the department recommends that most students start their Yale econometrics training with 117.

Economics majors must take an econometrics course in the Yale department. If you feel you have covered the material in Econ 117: Introduction to Data Analysis and Econometrics in another course, speak to the professor for Econ 123: Intermediate Data Analysis and Econometrics about taking that course. Students may also fulfill the econometrics requirement with a more advanced course, such as Econ 419: Financial Time Series or Econ 420: Applied Econometrics.

Another option for meeting the econometrics requirement for those with greater math preparation is to take Econ 135 followed by Econ 136. Econ 135 requires Math 118 or 120 and Math 222 or 225. Econ 136 requires Econ 135.
