What we will do in class tomorrow instead

I plan to review and extend our discussion from last week - mainly about the examples from M&R chapter 1 and additional ones I supply.  Then we'll briefly talk about transaction costs, which is the beginning of new stuff.  That is in the middle of M&R chapter 2.  I will got back to talk about efficiency on Thursday.

I do not plan to go the full time.  For those of you who do not watch the tutorial videos ahead of time, you can use the extra time for that purpose.
