"GTAP-DD: A Model for Analyzing Trade Reforms in the Presence of Duty 
Drawbacks" by Elena Ianchovichina

Notes:
All initial data files, sets and parameters files are stored in 
\techpaper\data. The sets file is sets.har 
GTAP model in \gtap6.1\gtap.tab 
GTAP-DD in \gtap6.1\gtap-dd.tab
Please look at the cmf file for a description of the input and output files.
Use techpaper\data\dechk.tab to check the split data 
Use techpaper\data\gtapview.tab to view the split data
Shocks to eliminate tariffs and export taxes are computed with split.tab
Shocks for the WTO experiments are computed using 
\techpaper\shocks\tmshockchn.tab for China and tmshocktwn.tab for Taiwan

1. Producing data for GTAP-DD 
1.1 Initial data 
1.1.1. with tariffs in China at 1997 levels
\techpaper\data\gdata97.upd
1.1.2  with tariffs in China at 1995 levels
\techpaper\data\gdata95.upd
1.2 Spliting the data
1.2.1 Almost all imported investment goods in China are duty exempt
1.2.1.1 Use split.tab and split97.sti to obtain split97.har and 
then modhar with modhar97.sti to obtain newdata97.har
1.2.1.2 Use split.tab and split95.sti to obtain split95.har and 
then modhar with modhar95.sti to obtain newdata95.har
1.2.2 Alternative specification of duty exemptions for imported investment 
goods
Use splitv2.tab and split97v2.sti to obtian split97v2.har and 
then modhar with modhar97v2.sti to obtain newdata97v2.har
1.3 Removing tariffs on imported inputs used for the production of exports
1.3.1 Data with 1997 tariffs and almost all imported investment goods 
are duty exempt 
Run \gtap6.1\gtap-dd.tab using \techpaper\data\tmsexpchn97.cmf 
The experiment produces the initial data \techpaper\data\gdata-dd97.upd
for the WTO accession experiment which involves liberalization from 
1997 tariffs
1.3.2 Data with 1997 tariffs and alternative specification of duty exemptions
for imported investment goods
Run \gtap6.1\gtap-dd.tab using \techpaper\data\tmsexpchn97v2.cmf. 
The experiment produces the initial data \techpaper\data\gdata-dd97v2.upd
for the WTO accession experiment which involves liberalization from 
1997 tariffs and uses the alternative specification for imported investment
goods
1.3.3 Data with 1995 tariffs
Run \gtap6.1\gtap-dd.tab using \techpaper\data\tmsexpchn95.cmf. 
2. Conducting the experiments
2.1 WTO accession from 1997 tariffs without duty exemptions
Run gtap6.1\gtap.tab using \techpaper\wto97.cmf
2.2 WTO accession from 1997 tariffs with duty exemptions
Run gtap6.1\gtap-dd.tab using \techpaper\wto-dd97.cmf
2.3. WTO accession from 1995 tariffs without duty exemptions
Run gtap6.1\gtap.tab using \techpaper\wto95.cmf
2.4 WTO accession from 1995 tariffs with duty exemptions
Run gtap6.1\gtap-dd.tab using \techpaper\wto-dd95.cmf
2.5 WTO accession from 1997 tariffs without duty exemptions and alternative 
specification of duty exemptions for imported intestment goods
Run gtap6.1\gtap-dd.tab using \techpaper\wto97v2.cmf
2.5 WTO accession from 1997 tariffs with duty exemptions and alternative 
specification of duty exemptions for imported intestment goods
Run gtap6.1\gtap-dd.tab using \techpaper\wto-dd97v2.cmf
