I did eventually read both Mankiw and Krugman.<br /><br />I started with Romer's grad text though. I figured Econ grad school admitted students that weren't Econ undergrads (e.g. Noah Smith was a physics undergrad) so it would be fine to start at the grad school level.Jason Smithhttps://www.blogger.com/profile/12680061127040420047noreply@blogger.comtag:blogger.com,1999:blog-6837159629100463303.post-9352607539450218162016-03-14T17:06:44.441-07:002016-03-14T17:06:44.441-07:00Say, maybe what you need to get your econ course o...Say, maybe what you need to get your econ course off to a good start is a little name recognition.

I ran that past Nick Rowe and he dismissed that out of hand, sounding a little annoyed... "No! Just a normal intro text... Mankiw or Krugman... doesn't matter!" (paraphrasing) :D<br /><br />I asked John Handley what he read to get up to speed... he just said papers and slides he found online: no books.Tom Brownhttps://www.blogger.com/profile/17654184190478330946noreply@blogger.comtag:blogger.com,1999:blog-6837159629100463303.post-80054236397345767022016-03-14T16:38:18.206-07:002016-03-14T16:38:18.206-07:00Yep, that's the one.

http://www.bondeconomics.com/...If it is this post:<br /><br />http://www.bondeconomics.com/2016/03/models-are-not-frequency-invariant.html<br /><br />then it still misses the point. He is talking about sampling error. That does affect all finite difference models, but isn't what I am talking about.<br /><br />I was talking about the first finite difference not nailing down the curvature without auxiliary assumptions (the graphic is <a href="http://informationtransfereconomics.blogspot.com/2016/03/more-on-stock-flow-models.html" rel="nofollow">here</a>). This only affects models of the type that specify dynamics via a single finite difference (such as G&L's SIM). You could specify a second derivative -- which would push the assumed implicit time scale to a higher order derivative.<br /><br />It's not the discreteness of those red curves in the graphic (sampling error), but the fact that an infinite number of them go through the two end points (therefore the blue curve is an implicit assumption).Jason Smithhttps://www.blogger.com/profile/12680061127040420047noreply@blogger.comtag:blogger.com,1999:blog-6837159629100463303.post-19160349933002452092016-03-14T14:32:20.316-07:002016-03-14T14:32:20.316-07:00BTW, Brian Romanchuk did another post with you fig...BTW, Brian Romanchuk did another post with you figuring in the body of it.Tom Brownhttps://www.blogger.com/profile/17654184190478330946noreply@blogger.comtag:blogger.com,1999:blog-6837159629100463303.post-1901701117061029822016-03-14T14:29:51.139-07:002016-03-14T14:29:51.139-07:00Nice!

I asked you about this once and you gave a brief reply, but this a much more complete answer.<br /><br />"...in the counterfactual world where the information transfer framework takes over all of economics."<br /><br />Lol! Nice positive attitude. <br /><br />BTW, I didn't realize the sad story of Boltzmann's demise. It seems weird he had peers telling him they didn't believe in atoms... I figured the chemists had that pretty well nailed down by the time he started his career.Tom Brownhttps://www.blogger.com/profile/17654184190478330946noreply@blogger.com
