COMPUTER CODES AND OTHER MATERIAL
(Note: Matlab has introduced a function called sym2cell which conflicts with my function with the same name. I have renamed my function as mysym2cell and had to change all codes accordingly. I could not re-test all codes. Please let me know if you have problems running them. Thanks -- 4 April 2018)
(Note: Matlab (2017b) has introduced two new functions cell2sym and str2sym and modified the way 'sym' works. I have updated the utilities and OPDSGE accordingly. Please if you find inconsistencies report to me. Thanks. -- 11 October 2018)
UTILITIES: NECESSARY to run any of the codes below (IMPORTANT!!)
The Optimal Policy for DSGE folder has been renamed (formerly lq_solution):
The main function name hase been changed to better reflect what the program does.
What does this package do?
These functions compute optimal (Ramsey) policies in closed and open economies (for arbitrary objective functions) and create a .mod (Dynare) clone where policy rules are replaced with non-linear FOCs of the policy problem. Steady state files are also updated (might require small amendments by users due to variety of ways in which users solve for the steady state).
For open economy models OPDSGE can compute both cooperative and non-cooperative (Nash) equilibria.
These function can ALSO be used to derive LQ representations (not priority of this project).
NB: previous versions computed SOCs. This option has been removed as the computation was incorrect (05 April 2018).

Could be used to find state-space solution as alternative to e.g. Dynare (e.g. for x-checking)

(Note: Some codes might not work under Matlab R2012b or newer. I've made some amendments to some codes to fix this problem but I have not checked all the codes.
Please drop me an e-mail if codes don't work. I might find some time to fix them.)
R codes and material
I've written a short memo on basic functions and tricks for R as my personal guide. If you are a beginner, you might find it useful too (HowToR).
