Upcoming Assignment

Problem Set 4 (on classes 2.4-2.7) is due by 11:59 PM Friday October 21 on Blackboard Assignments.

Overview

Today we briefly discuss revenues before we put them together to solve the firm’s profit maximization problem. We focus on the short run, where the firm incurs fixed costs and must stay in the market regardless. We derive the firm’s (inverse) supply curve.

Next class will be about the long run, and finish up unit 2.

Readings

  • Ch. 8.1-8.3 in Goolsbee, Levitt, and Syverson, 2019

Practice
