Notes on Microeconomic Theory

The following notes were designed to accompany API 109i and API 111 / Econ 2020a / HBS 4401 (Harvard University).  They provide commentary on the text and contain most of what I cover in lecture.  However, they are not meant as substitutes for the text or lectures, which are the ultimate guide to the material in the course.

The notes are meant to accompany, not replace, the recommended texts for the course.  The recommended texts are:

Main Economics Text:

Mas-Colell, Whinston, and Green, Microeconomic Theory, Oxford University Press (1995).

The notes are still in a preliminary stage.  As such, they most likely contain typographical errors and confusing passages.  I ask that students keep this in mind if they choose to use these notes.  I welcome comments from students regarding errors in the notes or places where they can be made clearer.
