Intermediate Microeconomics (Undergraduate)

Announcements:

• Exam #1 is scheduled on Tuesday, October 27, 1PM-3PM at F103. It consists of 5 questions covering Consumer Theory and Choice under Uncertainty (no producer theory). Format is similar to the previous year's exam. Any update, if any, will be posted here.

• Saturday, October 10 is on Wednesday schedule. Because this gives Wednesday class an extra class day that Thurwsday class will not be able to make up, we have decided not to hold a regular class on this day. Instead, we will go over some questions from 2025 midterm and problem sets. The class will be held at the usual location, J101. For students in Thursday class, please note that solutions to the midterm and problem sets are posted below so that you do not miss anything.
Update: We went over 2025 Midterm Questions 1 and 2, 2025 PS2 Question 1, and Consumer Theory Additional Exercisesn Question 22. I am availalbe for appointment if anyone from Thursday class would like to go over these questions with me.

• New Classroom: THURS 1:00 - 3:35PM class now meets at C405. Wednesday class is unchanged.
