Why are
you here?

"Individual consumer and firm behavior
under perfect competition.

The role of markets and prices in a decentralized economy.

Monopoly in partial equilibrium.

Economic tools developed from multivariable calculus using partial differentiation
and techniques for constrained and unconstrained optimization."

It's probably not the sexiness of the course description:

• Money and Banking (Econ 111)
• Decision Modeling and Information (Econ 137)

Course Structure and Policies

Before Lecture

• Read the textbook and take online quizzes on the major points to be prepared for learning in lecture

• Presents new ideas
• Illustrate those ideas with simple examples

• Exercises for each lecture are designed to help you understand nuance
• More complex examples and applications than in lectures; work on connecting the dots

• Exam questions will ask you to apply concepts from lecture to new situations you haven't seen before.

Pre-Class Quizzes and In-Class PollEverywhere (10% of your grade)

• Purpose: get the most out of lecture, by providing incentives to
  read the textbook before class and be fully present during class

• Each category counts for 5% of your grade.

• Each category has a 20 percentage point "boost":
  if you get 80% or more right becomes 100%, 70% becomes 90%, etc.

• Realistically, as long as you come to most classes and put in effort
  into each of the quizzes, these don't affect your grade.

• You do not need to email me if you're going to miss class.
  You cannot "make up" PollEverywhere points.
  Just make every effort to make it to every class you can.

If you're going to miss class, what should you do?

Homework (25% of your grade)

• Due each Tuesday and Saturday (none after an exam).

• Each exercise (including old exam questions) is worth 3 points.

• The grade is a message:

  • 3 points (check-plus): You've got this!

  • 2 points (check): You should review the solution set.

  • 1 point (check-minus): You should review this material.

• You do not have to do them all. Recommend doing 2-3 problems in each.

• Full credit (100 points total) for 6.66 points per problem set.

• Maximum 9 points per problem set.

• No homeworks accepted after 8am morning after due (automatic grace period until then)

• You must assign pages in Gradescope to get your work graded!

pollev.com/chrismakler

If you don't have much time for homework, what should you do?

Checkpoint Exams (30% of your grade)

• Fridays of Week 4, 6, and 8

• Meant to be a way for you to self-assess and keep on track

• Three exams means that the stakes are lower for each one than if we had one "killer midterm:"

  • Highest score is 20% of your grade

  • Second highest score is 10% of your grade

  • Lowest score is dropped

• Note: if you miss two checkpoints, your highest possible grade in the course is a 90%.

• Assume you will get COVID for the third exam, which will prevent you from taking it.

Final Exam (35% of your grade)

• Wednesday, June 12 at 8:30am (set by University)

• You must take the exam here in person unless you're traveling on Stanford business, or if you've started a summer job or internship; sorry.

• If you have a summer job or internship, you are responsible for finding someone official to administer the test concurrently with the rest of the class. We need to know who that's going to be by Memorial Day (end of Week 8).

• If you have to miss the final due to illness or emergency, you may take an Incomplete only if:

  • You scored a C or better on at least two Checkpoint exams, AND
  • You have a (curved) score of at least 80% on your quizzes and PollEverywhere grades (so a raw score of at least 60%), AND
  • Your homework score is at least 80 points

Advice for You from Former Students (from course evals)

The Small Print

• Names and pronouns
• Students with documented disabilities
• Stanford University Honor Code
• Econ Department syllabus
• Humor gone wrong

Office Hours

• Come to office hours! Starting later this week...watch ED for details.
• Try your hand at the homework before coming to office hours; don't just come and do the homework in front of me. Then come with points of confusion and we'll talk through it.

Before Next Class

• Be sure you've filled out the section form
• Read Chapter 2 of the online textbook
• Take the quiz
