Dear Jonathan,

I have never tried this before and I have to say I really like it. I had no idea you could record your audio on a ppt. Something to think about down the line is how to host such power points for all of us to see. There are two services that work well. (1) SlideShare and (2)AuthorStream. I am on the latter. (http://www.authorstream.com/Amyaz_M/). I have started to put my invited public talks here. One thing to think about is about if you do not want to mess with upload, and everyone you want to see your slides has ppt, then its best to load it on Google Drive. A brief survey of sharing options is here: 

I will give content suggestions shortly.

Cheers,

Amyaz.

Jonathan:

 

I liked this a lot as well.  As one who suffers valid criticism for slides that are too busy—usually with bullet points that try to be accurate at the cost of wordiness—I think recording will help with this problem.  I plan to experiment with some of my powerpoints to see if I can do this effectively.

 

A couple of minor comments on presentation: (1) Early on I’d realign the leakages/injections labels so that the formulas that appear immediately below them are on the correct side (right now they are reversed).  It’s a small point, as you make clear which is which subsequently in the presentation, but it looked odd to me as I watched it.  (2) Because there was not audio for the next to last slide I initially missed the final one, which I gather you intend to have as an appendix.  Some indication that it’s there of that would help.  I also felt that the presentation ended a bit abruptly, but that may be inevitable and certainly is a problem I’m having as I experiment with my own stuff.

 

Substantively, my only issue was that at times it was unclear (to me at least) whether you were shifting from the ex post identity to the ex ante equilibrium condition for injections=leakages as you progressed into the three balances.  I do like the grouping them as you did and make a point of exploring the various implications myself.
