README file for the replication package of the paper "Growth through learning" by Boyan Jovanovic (NYU) and Sai Ma (Fed Board) for the RED special volume honoring Thomas F. Cooley. 1. Software and operating system used All the codes were written and tested under Windows 10 and Matlab 2019a. They are not tested in other operating systems or other versions of Matlab. 2. Any particular computing setup was used? Some of the programs require the CompEcon toolbox available at https://pfackler.wordpress.ncsu.edu/compecon-download/. The toolbox is open source, and please change the directory in the code that loads the CEtool folder. (The default path is Sai Ma's local PC) 3. The order in which the programs need to run To get all the figures in the paper, run the corresponding gen_FigureX.m file on Matlab. Note that Figures 3, 5, and 7 are jointly produced by gen_Figure357. Figures 13, 14, and 15 are jointly produced by gen_Figure131415. 4. Expected computation time Each code should take no more than 1 minute. The corresponding figure will pop up in Matlab. 5. If random numbers are used, the seed needs to be specified, as well as the random number generator. There are no random numbers used in all codes.
