A note drawing strands together from Lecture 1 is here.
Outside my office door, please find (and help yourselves to) the article on orca preservation -- it's two sheets long. As mentioned today, local and planetary extinctions are not to be taken lightly: the State of Washington is willing to spend $1billion avoiding the former.
In preparation for next lecture, you might take a look at the Introduction to J-J Laffont's classic text. The formality is a large part of what is important here. (I like the way he puts it: "Before beginning this book, the reader should have a complete understanding of the two fundamental theorems of welfare economics derived from the 'basic microeconomic model.' " No less...!)
Arrow-Debreu (1954) is the classic of the genre. You will find a copy outside.
(Arrow was a very remarkable scholar. His NYT obituary from February 2017 is worth reading.)
Next Tuesday, January 22, the lecture will begin a bit after 5:30pm, in light of Max Kasy's talk in GE 106, starting at 4:10pm. I recommend that everyone who is free should attend. (More to follow on that...)
