Lean Economics now has own @LeanEcon. Formalized lots of textbooks, every result.
Formalized textbooks:
Dynamic Programming: Sargent & Stachurski (Vol 1 & 2); Stokey, Lucas & Prescott
Monetary: Gali (NK); Woodford (interest & prices); Cochrane (fiscal theory).
International: Obstfeld & Rogoff
500+ corrections (mostly tiny or typo)

Current: prove existence of stationary general eqm for Aiyagari 1994, plus uniqueness for mu=1 (already known, now Lean formalized).

and live! The Economist locks theirs so you cannot use in teaching. 17 Big-Mac-Less countries: Iraq is included with the substitute "MaDonal BigMack", and Iran with "Mash Donalds Tehran Combo", North Korea is burger-less.

Publication using VFI Toolkit:

OLG model with two endogenous states, assets and human capital. Toolkit commands solve the OLG and calibrate eqm to match life-cycle microdata. Then perform optimal tax exercise.
VFI Toolkit handles it all comfortably!

Life-Cycle Model 27 demos how to use the Guvenen, Karahan, Ozkan & Song (2021) earnings processes. My new article explains the discretization method, and the implications.

GMM Estimation of Life-Cycle models
shorturl.at/lvnU9
Life-Cycle models 45-50 in the Intro to Life-Cycle models show how to do GMM estimation in VFI Toolkit with just 5-10 lines of code (after model and data work). I'm excited about this! :D

getIMFData() adds GFS databases. Requires minor update to inputs for CPIS and DOT databases. See github for example using GFS.
getHDRData: download data from Human Development Report directly from within Matlab:
