I am working with the GTAP in some trade policies simulations. I would like to quantify the impact of some trade policies that include conditions on rules of origin. I am aware that, unless I generate a new sector , I will not be able to properly design the shock. However, I think that I can simulate the trade policy implications by an import subsidy plus a tax on domestic consumption and on exports. The problem is that in the standard closure, taxes on domestic and imported purchases by firms, private households and government are not exogenous (tfm, tfd, tpm, tpd, tgm, tgd). My question is how can I exogenize these variables, that is to say which variable should become endogenous instead. Thank you very much for your help....

I am having a confusion about interpretation of ao [j,r] and aoall [j,r] in RunGTAP Tablo file [Version 5]. They are defined as:
Variable (all,j,PROD_COMM)(all,r,REG)
ao(j,r) # output augmenting technical change in sector j of r #;
Variable (all,j,PROD_COMM)(all,r,REG)
aoall(j,r) # output augmenting technical change in sector j of r #;
Variable (all,j,PROD_COMM)
aosec(j) # output tech change of sector j, worldwide #;
Variable (all,r,REG)
aoreg(r) # output tech change in region r #;
Then, there is an equation:
Equation AOWORLD
# sector/region specific average rate of output augmenting tech change #
(all,j,PROD_COMM)(all,r,REG)
ao(j,r) = aosec(j) + aoreg(r) + aoall(j,r);
What is the diffrence between ao[j,r] and aoall[j,r]? and is ao [j,r] endogenous and aoall[j,r] exogenous? -- what does the equation convey intuitively?...

Can anyone provide me with advice on how to make GTAP mimic a change in exchange rates? For example how would you impose a 10% depreciation of the Canadian dollar against all other currencies?...

How does one efficiently change each country's initial tms for imports of goods from all other regions with x percentage points (ie ordinary change to the tariff rate). How can this be done in GTAP?...

I appreciate if anyone can give me hint regarding the amount of memory RAM we need to run the full RunGTAP. We're thinking in upgrading our computer systems and we have to consider the needs that models as RunGTAP and GTAPDyn impose. In particular we know that, for instance, the full RunGTAP model does not run in my PC with one giga memory -I get a message "unable to allocate sufficient memory. (I0STAT is 912)". Does anyone know how much memory is needed to run the full regional and sectoral specification model? In the case of GTAPDyn, how much is needed? Do you think it is advisable a more powerful computer like those with dou-processors? Are GEMPACK and RunGTAP compatible with UNIX? I have heard that is not feasible to expand the memory RAM further than 2 GB using the standard XP Professional, is that right? Overall, what do you advise: upgrade the memory RAM of the current PCs and run the models with UNIX or any upgrade WINDOWS or the acquisition of a type "server" system?...
