(Feb. 14, 2014) I will mostly use this website to post any additional question/note that I used in the recitation. In addition, from Homework 3 and on, I will add a Q&A section on this website. Any “useful” question I get from email related to the homework will be posted in the file named “Q&A Homework #” pdf file (for example, “Q&A Homework 3 — Updated Feb/15”), and will be updated from Monday to Thursday. Hope this can help you prepare the homework

Recitation materials:

Some Concepts/Reviews on Consumer(Household) Problem

This file is more like demonstrating how this website works. The file is my recitation slide for Intermediate Micro last year. It contains some important concepts e.g. monotonicity, Lagrangian and MRS = Price Ratio method, in addition, at the end, there are Four questions on partial derivatives, hope this helps. Again, you are NOT responsible for the concepts that were not covered in this file for this course
