II. EXPERIMENT FILES: SHOCKS, CLOSURES AND SOLUTION METHOD

There are three different experiments, distinguished only by the shocks applied:

exp1  APEC Preferential Free Trade Area.  Import protection
         within the nine APEC regions is removed (both tariffs
         and NTBs) but maintained between the rest of the world
         and APEC.

exp2  APEC Trade Reform on a Most Favored Nation Basis
         (MFN); ROW does not reciprocate.  The nine APEC
         regions remove import barriers for all regions
         including ROW: however ROW does not reciprocate.

exp3  APEC Trade Reform on an MFN Basis; ROW reciprocates.
         Import barriers for all regions are removed, however
         they remain in place for ROW-ROW trade.

The experiments are cumulative: all the exp1 shocks are included in exp2; in turn all the exp2 shocks are included in exp3.

To replicate the experiments with RunGTAP go to the SOLVE page, click on "Load Experiment" and choose either EXP1, EXP2 or EXP3.  This will automatically load the shocks, the closure and the solution method for the experiment of interest.

CLOSURE
The  standard "Book"  multiregional GE closure (MRGE) is used in all three experiments.

SOLUTION METHOD
An interesting feature of these experiments is that they demonstrate the non-linearity of the GTAP Model to a marked degree. This is shown by the variation in results as the solution algorithm breaks down the exogenous changes into more, smaller, steps.

In case your computer is slow, the supplied experiment files specify the solution method as:
     method = Gragg; steps = 2 4 6 ;
but many more steps are needed for reasonable accuracy.  To obtain results similar to those reported in the GTAP book, try
     method = Euler; steps = 10 20 30 ;
It turns out with hindsight that even this is insufficient. Go back to
     method = Gragg; steps = 2 4 6 ;
but this time switch ON automatic accuracy.  This will give better accuracy than the Euler solution, in less time.

Test your RunGTAP knowledge !
In each experiment, the shock statement mentions a set APEC.  Use the View..Subsets and Variables menu command to discover what regions are included in APEC.
Notice that the APEC set is not defined either in the the SETS file (View..Sets) or in the main TAB file. Where is the APEC set defined?
