GTAP Live Forum: GTAP 7 Data Base (January 13, 2009) Chat Transcript Antimiani-Velazquez: yep phouphet kyophilavong: yes Cristina Vinas: yes Andrew Larson: Yes, Andrew can here you, but we don't have a microphone. Andrew Larson: No, thanks. Dinh: As my understanding, the base year can be changed though the I-O table can be kept. So the conversion factor may also matter. Is that right? Dinh: sorry, I dont hear you very well Badri Narayanan Gopalakrishnan: Dinh, can you hear Tom speaking? Regina Fuchs: but the shares across energy goods change a lot! Robert A McDougall: Dinh: We don't have separate currency conversion and updating steps; we just apply one scaling factor to get GDP to a target value in millions of US dollars for the database reference year. Badri Narayanan Gopalakrishnan: Mia Mikic asked about Laos and Cambodia Dinh: thank Mr. McDougall. Somehow I dont really understand the data on GDP aggregates (C,G,I) which are used in FIT (an application of entropy-theoretic methods to adjust an I-O table to various external constrains. Can you explain more a litle bit about that? Thank you very much Badri Narayanan Gopalakrishnan: For these and other IO tables, please refer to the documentation: http://www.gtap.agecon.purdue.edu/databases/v7/v7_doco.asp Antimiani-Velazquez: have youheard our question? Robert A McDougall: Dinh: FIT is a complicated program, but for (C,I,G) targeting it works just like a Leontief (I-O) quantity model. Final demand changes to meet the targets, and the I-O table adjusts to maintain the I-O coefficients. Badri Narayanan Gopalakrishnan: For detailed information on FIT please refer to v6 Documentation from http://www.gtap.agecon.purdue.edu/databases/v6/v6_doco.asp Dinh: I see. However, in slice 22, Alternative format, the last scentence is ''Adop standard SNA and I-O terminology: i.e,, leanrn to talk their language''. What does it mean? Is it suggests that we use I-O analysis in addion to CGE analysis? Thank you. Antimiani-Velazquez: Could you please confirm that TF for agriculture in EU27 Member States is implemented considering a full implementarion of the 2003 reform? if yes this wouldmean that TF corresponds to 2010. Mia Mikic: slide 22 Mia Mikic: can someone at GTAP take stock of all question and follow up with short refereces for answers through email? Antimiani-Velazquez: we cannot hear you Willem Ruster: What is the normal procedure to extract an IO table out of the database/HAR-files? I've constructed several tables, but my problem still is that the rows differ from the columns. Regina Fuchs: again an energy question: in GTAP7, are the renewables, biomass, nuclear,... still discarded? Robert A McDougall: Regina Fuchs: Yes, the energy volume processing is still very much as in release 6. Badri Narayanan Gopalakrishnan: Here is a link that Willem needs to see for SAM extraction: http://www.gtap.agecon.purdue.edu/resources/res_display.asp?RecordID=1645 Antimiani-Velazquez: For Domestic support in general in EU25 is not available at country level (we confirm OECD does not calcualte it at MS level) then it is equal for all MS. In that case, are the observed differences, e.g. in TF due to differences in land values? Badri Narayanan Gopalakrishnan: Antimiani: could you please clarify what's TF? Dinh: I understand the importance of data contributed. So can I ask what is the benefit of the contributor? Terrie L Walmsley 2: For relatiopnship between IO table and GTAP Data Base see http://www.gtap.agecon.purdue.edu/databases/contribute/documents/gtaptoAI.pdf Antimiani-Velazquez: tax or subsidies on factors Badri Narayanan Gopalakrishnan: Contributor recieves full database free of cost Terrie L Walmsley 2: For reltionship between SAM and GTAP Data Base see : http://www.gtap.agecon.purdue.edu/resources/res_display.asp?RecordID=1645 Dinh: what about the license of the program Antimiani-Velazquez: we cannot hear you badri Antimiani-Velazquez: thanks Antimiani-Velazquez: PLs remeber we asked 2 questiosn Badri Narayanan Gopalakrishnan: We recieve domestic support data on EU member countries separately Antimiani-Velazquez: now we here you Antimiani-Velazquez: it is not! Antimiani-Velazquez: not lear to us. Because we noticed TF is the same in one country for all commodities Antimiani-Velazquez: ok this menas full decoupling roberto telleria: What about domestic support data for Latin American countries? Dinh: can I ask about the numeraire? Is it pfactwld (world price index of primary factors) or what? thank you. Antimiani-Velazquez: For Domestic support in general in EU25 is not available at country level (we confirm OECD does not calcualte it at MS level) then it is equal for all MS. In that case, are the observed differences, e.g. in TF due to differences in land values? Antimiani-Velazquez: thanks Dinh: thanks Badri Narayanan Gopalakrishnan: http://www.gtap.agecon.purdue.edu/events/Short_Courses/2009/default.asp Badri Narayanan Gopalakrishnan: PLease see this link for details on the short course Rehab Osman: hello, i have noticed that many modification have been done in trade data; updating goods trade data and modifying the underlying methodology for collecting service trade data. What about trade elasticities; are they altered concequently? If no, is it on oyur improvment agenda? Thanks Dinh: Before I ask about the defence for the time difference between country I-O table when analysing trade partners changes due to tariff reduction. Is there any good execue for that? Thank you. Antimiani-Velazquez: About import tariffs, the data base is from the MAcMap, based on UNCTAD Trains. I know that the way they are weighted is different, i.e. reference group for macmap, what one have you used in this databse version? Dinh: you meand GTAP Aggregate licence or RunGTAP licence, or GEMPACK licence? Robert A McDougall: Dinh: Whatever the reference years for the I-O tables, we fit them all to GTAP reference year trade data. So the final data base should be time-consistent. Antimiani-Velazquez: ok, thanks Stuart: Australia, NZ, Canada have been on the most wanted list, Australia was 1998. GTAP7 documentation says it is still 1998 but presentations today suggest these are now updated. What is the background to this situation please? Dinh: oh, I see, thanks Mr. McDougall. Antimiani-Velazquez: we cannot hear t Hertel Dinh: ok Antimiani-Velazquez: good Andrew Larson: Is it possible to extract a SAM for an economic region that overlaps with parts of two or more countries? Antimiani-Velazquez: yesss Robert A McDougall: Andrew Larson: It's possible to extract a SAM for a region that includes several GTAP regions: first aggregate the data base, then extract. Dinh: Mr. Hertel, so the trade elasticities will be different from database version to version? Stuart: Is GTAP moving from IO to UV? If so, will the Make matrices become full rather than diagonal at present? Regina Fuchs: is it possible, to provide more detailed information/documentation on the allocation rules of energy? we compared IEA data with GTAP6 energy volume data (2001). some of the discrepancies could be explained by the documentation: electricity losses, transport fuels, etc. I know your resources are limited but sometimes it feels a little like a black box! Dinh: Thank you. Hoda El-Karaksy: No sound Stuart: Terrie, can't hear you! Regina Fuchs: no Antimiani-Velazquez: no sound phouphet kyophilavong: I can not hear Rehab Osman: i can not hear your answer Badri to Dinh qes!! Terrie L Walmsley: License info is at http://www.gtap.agecon.purdue.edu/products/requirements.asp. Robert A McDougall: Stuart: What is UV? Anyhow, there is no plan to provide full make matrices for the standard data base (we may use them a bit behind the scenes). Stuart: Thanks Robert (U is Use, V is Make) Badri Narayanan Gopalakrishnan: ok, my answer to Dinh's question was that trade elasticities need not vary from version to version Badri Narayanan Gopalakrishnan: They are updated using literature, but not necessarily in all versions Badri Narayanan Gopalakrishnan: They have not been updated in v7 Rehab Osman: thanks but no sound at the moment Terrie L Walmsley: Australia and New Zealand are not on the most wanted list. Australia was updated in v7 by the Productivity Commission in Australia and hence this is the best they have. Badri Narayanan Gopalakrishnan: Since many users are unable to hear, we'll respond by typing henceforth Stuart: Thanks Terrie for Australia position Terrie L Walmsley: For latest info on IO tables see http://www.gtap.agecon.purdue.edu/databases/contribute/iotables.asp Badri Narayanan Gopalakrishnan: I would also like to remind users about the 2009 Chile conference Xiaolin: are you plan to add the biofuel data for gtap 7 soon? will celulosic ethanol be added too? Badri Narayanan Gopalakrishnan: Deadline for abstract: coming Thursday Hoda El-Karaksy: so elasticity in v6 same as v7 Badri Narayanan Gopalakrishnan: Yes Robert A McDougall: Regina Fuchs: We have a long-term goal of releasing the construction programs themselves. I'm not sure whether there's a useful intermediate step between that and the documentation as currently released, but suggestions are welcome. Dinh: back to the benefit of the contributor, I think it is very costly to contruct an I-O table. So it seems may not be satifactory to have only full use of database. Terrie L Walmsley: Andrew, yes. Tech paper oon SAMs takes GTAPAgg output and constructs SAM for this country/region. Uses a batch file - very easy. See gempack version. Badri Narayanan Gopalakrishnan: Xiaolin's q'n: There is no plan to add bio-fuel and cellulosic ethanol data for GTAP 7 Xiaolin: thanks Stuart: Terrie, thanks for your SAM program, it is very good, only issue is that all identified matrices in Working Paper are not available in the database. Badri Narayanan Gopalakrishnan: But there has been some work in the center on biofuels, so you may refer to this working paper: http://www.gtap.agecon.purdue.edu/resources/res_display.asp?RecordID=2413 Xiaolin: thanks, Badri Terrie L Walmsley: Stuart, send me more details and I will check with author. Stuart: Terrie, will send some thoughts Robert A McDougall: Dinh: According to standard GTAP doctrine, the best motive for contributing an I-O table is that you want it in the GTAP Data Base. Yes, it is a lot of work, but much less than doing a multi-country data base by yourself. Terrie L Walmsley: Dinh, agreed contributors would like more, but we can't afford to pay for data. Rehab Osman: What about income and factor taxes - previously, income taxes were summed within the distribution of income of the regional households as fixed sahers. Does this change in G7? Terrie L Walmsley: GTAP not planning on moving to non-diagonal matricies in near future. Badri Narayanan Gopalakrishnan: No the treatment of income/factor taxes did not change in v7, it remains as in v6 Terrie L Walmsley: But hoping to support contributors with more programs to convert alternative formats. Badri Narayanan Gopalakrishnan: Rehab, hope I answered your q'n? Dinh: I see. Thanks for your answers. Rehab Osman: yes, but i wonder if terrie's respond is for my qes? Badri Narayanan Gopalakrishnan: No, Terrie's was for Dinh's Terrie L Walmsley: Dinh - not sure I understand question about different time periods for tariffs. Assume this is a problem that policy makers are saying you have data which is 2004 and we want 2007. If so you can update the data first by running a sim to move you to 2007 first and then do your policy shock. Also might want to look at altertax if you want to change protection you disagree with. Rehab Osman: thanks Badri it is just confusing since no audio interact exists Regina Fuchs: from the GTAP-List and the FAQ I found out that there are people trying to link national I/O data to GTAP for single countries. Are there any papers concerning this issue, or what's your opinion about that? Dinh: sorry, how can I do the simulation for 2007 based on base year 2004? Dinh: yes Cristina Vinas: yes Antimiani-Velazquez: yes Andrew Larson: Is there anything new for Brazil? phouphet kyophilavong: yes Rehab Osman: yes Hoda El-Karaksy: yes Stuart: Badri, can hear you Xiaolin: yes Andrew Larson: Yes I can hear. baowhwh: yes Terrie L Walmsley: Ues altertax when you don't like your protection data. Robert A McDougall: Regina Fuchs: Several papers, probably. One old one (1995) is Center of Policy Studies General Paper No. G-111, a GTAP-MONASH link (MONASH is model of Australia). Regina Fuchs: thx Terrie L Walmsley: Regina, yes alot of people do this if they want more detailed country info. An early example of this is: http://www.gtap.agecon.purdue.edu/resources/res_display.asp?RecordID=126 and the US are doing alot of this too. Badri Narayanan Gopalakrishnan: Andrew: for Brazil, the domestic support data and other non-IO features have been updated for 2004 Dinh: I see, thank you very much. But I thought without alter tax program, we can do simuation by adding new shocks to changes in protection. Is that OK? Badri Narayanan Gopalakrishnan: Dinh: Yes, you can do that, for changing the base year, where you will have many variables to be updated Dinh: thank a lot. Rehab Osman: Thomas please about Altertax program is it applicable only with RunGtap or I could use it under GAMS? Badri Narayanan Gopalakrishnan: Rehab: currently we have Altertax only with RunGTAP, but you can write a similar program in GAMS too Dinh: Thanks Mr. Hertel. Rehab Osman: thanks Hoda El-Karaksy: Is there any way to give us the link for this paper? Robert A McDougall: Hoda El-Karaksy: Which paper? Terrie L Walmsley: http://www.gtap.agecon.purdue.edu/resources/res_display.asp?RecordID=315 baowhwh: you can google Hoda El-Karaksy: sorry, about altertax Badri Narayanan Gopalakrishnan: ok Badri Narayanan Gopalakrishnan: Dear All, we just have 10 more minutes, so please remind us if we have'nt answered any of your questions! Apologies for the issues with technology. Hoda El-Karaksy: thanks! Antimiani-Velazquez: Thanks from us too Regina Fuchs: yes Hoda El-Karaksy: yes Antimiani-Velazquez: yes Cristina Vinas: yes Andrew Larson: yes baowhwh: yes Stuart: fine Xiaolin: yes phouphet kyophilavong: yes Dinh: technical change can be altered. But at the baseline, how did you estimate the technical parameters? Thank you Rehab Osman: it is not clear in the handout nor on the website how further dis-aggregation for labour, skilled and unskilled, could be done? Stuart: thankyou for this very useful session! Regina Fuchs: Thank you! Willem Ruster: One last question: i've received the following link: http://www.gtap.agecon.purdue.edu/databases/contribute/documents/gtaptoAI.pdf phouphet kyophilavong: thank you Willem Ruster: where can I find DFtax adn DPTAX Andrew Larson: Thank you very much from Minnesota! Willem Ruster: (and also IPTAX and IGTAX, IFTAX, ETAX) Jose Tongzon: thanks for a very informative session. hope we can have more of this. Terrie L Walmsley: Willem, this is for IO to GTAP Data Base Willem Ruster: Can you type that for me, please (about tax)? Cristina Vinas: Thanks for the session Dinh: ok, thanks for all Hoda El-Karaksy: Thanks for this session!!!!!!!! Terrie L Walmsley: Willem, see baserate.har Robert A McDougall: Rehab Osman: You'd have to get your own data source, and write your own program to do the splits. Willem Ruster: ok, thank you Antimiani-Velazquez: thanks for the session from Brussels phouphet kyophilavong: Thank you for this session Rehab Osman: Thanks a lot for you all it would very useful and appreciated if we could hold similar sessions in the fututre baowhwh: thand for this session Xiaolin: thanks for the session Willem Ruster: thanks for the session, have a nice day Badri Narayanan Gopalakrishnan: You are all most welcome. Thanks for participating in the session Badri Narayanan Gopalakrishnan: We shall post this session in the website and mail you all soon baowhwh: thank very much
