Introductory Courses

We encourage most first-year students who are interested in economics to take an introductory micro course in the fall and an introductory macro and/or introductory data course in the spring. Students have multiple options for introductory micro and macro in both semesters.

Introductory micro is offered in three formats:

  • Econ 115 is a large lecture class. 
  • Econ 110 covers the same topics but is taught in smaller sections that are only open to first-year students and sophomores. This class is restricted by lottery.
    Econ 108 is intended for students with limited or no experience in calculus. It places greater emphasis on quantitative methods and examples.

Introductory macro is offered in two formats:

  • Econ 116 is a large lecture class. 
  • Econ 111 is similar in spirit to Econ 110. It covers the same topics as 116 but is taught in smaller sections that are limited to first-year students and sophomore and are restricted by lottery.

Students who will be in their first or second year in fall 2021 and are interested in taking Econ 108, 110 or 111 in  that semester must enter preference selection between 9:00am on Monday, August 16, and 5:00pm Friday, August 20, 2021 (Click here for Econ 108; Click here for Econ 110; Click here for Econ 111 ).

Because there are a limited number of slots in these courses, places will be assigned randomly to a subset of those that enter preference selection. Assignments will be available on the preference selection site after 5:00 pm on Friday, April 30, 2021.

Questions about the preference selection lotteries should be directed to Also feel free to drop in on the DUS’ office hours for advising.

Introductory data analysis and econometrics:

  •  Econ 117 is a an unlimited enrollment large lecture class offered in both semesters. Given its emphasis on data analysis, the department recommends that even students who have taken statistics in high school should start their Yale econometrics training with 117. Students do not need a programming background to take econ 117.
