Steps when backing up your work: Run clean.bat Zip the contents of your model directory (NOT including the save [or zip  see below] subdirectory) Put date in your file name (so you know when it was created). Possible naming scheme for Tunisia s work on April 3: MAMS-Tun-2007-04-03a.zip, MAMS-Tun-2007-04-03b.zip, Etc.NYZ" Z;ZY;] File ManagementCreate a  zip subdirectory (next to the  save subdirectory)  put your zip files there. A good way of backing up: share zip file across all members of the country team. When discussing problems via e-mail, asking for backstopping: always send the complete zip file (not individual files; the different files are highly interrelated; run clean.bat first).eeS  File ManagementOnly keep necessary files in your model directory (necessary = needed to run the model in GAMS). Keep underlying data files, analysis, papers, etc. in other directories. After having created the full set of country-specific data files, do NOT change the names of the files that you are currently running (i.e., your  current version of DMOD2.GMS never changes name; if you want to keep an alternative version of DMOD2.GMS for future reference, give it a different name: DMOD2-SUPER.GMS.PFile ManagementA good software for comparing text files (like DMOD2.GMS in two different .zip files) is important. Options: Total Commander (www.ghisler.com) Winmerge (winmerge.org)&m:m:>~ File ManagementRationale for the above rules: Put a limit on the size of files that you share with other. Make it easier for others (and you) to understand (recall) exactly what files you are running and what has changed between different work sessions.&   Making progress YTeams are heterogenous; different team members may be doing different things. For GAMS, your model directory includes documentation. The website www.gams.com provides many other materials. For CGE modeling in GAMS, possible steps: Exercises in General Equilibrium Modeling Using GAMS and Key to Exercises in CGE Modeling Using GAMS.

Hans Lofgren, Rebecca Lee Harris, and Sherman Robinson with assistance from Marcelle Thomas and Moataz El-Said. www.ifpri.org/pubs/microcom/micro5.htm4Zr ZrN { r 1>0 Making progress ~Project will address training needs. Sources for learning about MAMS and its data: workshop presentations (.PPT files) the technical model document (Lofgren  Diaz-Bonilla) the Excel data sheet model in GAMS other MAMS applications project website Communicate  inside team; with backstopping group (problems, needs, & )BSPPHPSH Making progress Easy switch between two model versions:  MDG and  non-MDG ;  non-MDG version is very flexible in terms of disaggregation. Easier to make progress and solve problems step by step. Model is  validated through simulations, review of results, adjustments in data/assumptions. (You can t just set up the database; press a button; solve the model; report and analyze results.) wZw  Making progress Given the above, possible steps in testing model and data development. run  non-MDG version using macro database. (See the  test-macro database.) run  non-MDG version using meso database. (A database that includes the same sheets as  test-macro but  full disaggregation of activities, commodities, institutions, and factors). (Labor stock growth by education is exogenous; model does not address MDGs and education outcomes and system.) run  MDG version using MDG database. (See the  test-MDG database; same as (2) except for the addition of data related to logistic and CE functions for MDGs and education.)HZ"" ZH(     0` 33` Sf3f` 33g` f` www3PP` ZXdbmo` \ғ3y`Ӣ` 3f3ff` 3f3FKf` hk]wwwfܹ` ff>>\`Y{ff` R>&- {p_/̴>?" dd@,|?" dd@   " @ ` n?" dd@   @@``PR    @ ` ` p>> $(    6ṕ  `}  T Click to edit Master title style! !  0,܁  `  RClick to edit Master text styles Second level Third level Fourth level Fifth level!
