This archive contains a modified version of the standard GTAP model,
and is meant to provide applied examples of extensions on capital
accumulation and imperfect competition, as detailed (for the most part)
in the following GTAP technical papers:

 J.F. Francois, B.J. McDonald, and H. Nordstrom, "Capital Accumulation      
 in the GTAP Model," GTAP consortium technical paper, 1996.                                                     

 J.F. Francois, "Scale Economies and Impefect Competition in
 the GTAP Model," GTAP consortium technical paper, 1998.

The model runs off of the Global Trade Analysis Project (GTAP) dataset, and
fully incorporates the code of the standard GTAP model.  The different
additional features are implemented through additional GEMPACK code pasted
to the bottom of the basic TABLO code.  These additional features are
controlled through different closure swaps and parameter changes.

The additional GEMPACK modules provided with this
file (in the file SIMPLE.TAB) allow for monopolistically
competitive industries (i.e. firm-level product differentiation),
cournot competition under constant and increasing returns,
contestable markets with scale economies and average
cost pricing, and steady-state adjustment to capital stocks under
classical and Ramsey-type savings rules.

The aggregation for these examples is based on a 2 region, 3 sector aggregation
of version 3 of the GTAP dataset.

x                          RUNNING THE MODEL                                X
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

NOTE:  When running this model, model feautures are 
manipulated through a mix of policy shock "switches", paramater file
modifications, and closure "switches."

The model is based on GEMPACK, and GTAP users can work directly with the
*.TAB and *.STI files to produce a compiled version of the model for
replication of results.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
x                              THE EXPERIMENT                               X
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

THE EXPERIMENT:

	The policy experiment for all the *.CMF files (except for EXP6.CMF)
        is identical, and involves global free trade.
	The only difference is the specification of the model, which 
        varies with each experiment.  The model aggregation (defined in
        the file SMALL.TXT) is a Japan-focused 2 region, 3 good model.

	Experiment EXP6 involves a change in Japanese competition policy,
        involving a shift in the allowed degree of collusion in manufacturing
	from relatively collusive (halfway between perfect competition and
	monopoly pricing) to something very close to perfect competition.  The
	model structure is identical to that employed in EXP5.CMF.

	Note:  Experiments 1,2,4,5,6 involve national product differentiation
	(the Armington assumption), while experiment 3 involves firm level
        product differentiation.  For these experiments, the Armington
        structure is non-nested, to accomodate the theory in the
        model on cournot pricing (which as specified involves non-nested
        Armington).

README.1st      this file

	*.CMF FILES
EXP1.CMF        Global free trade under non-nested GTAP model        
EXP2.CMF        Same experiment, with IRTS and AC pricing in manufacturing
EXP3.CMF        Same experiment, with large group monopolistic competition in sector 2
EXP4.CMF        Same experiment, with cournot behaviour and CRTS in manufacturing
EXP5.CMF        Same experiment, with cournot and IRTS in manufacturing

NOTE!! You must run INSERT1.CMF and INSERT2.CMF before EXP4,5,6
This inserts Cournot markups into the base data.

EXP6.CMF	Same model as EXP5.CMF, but with change in competition policy
EXP7.CMF        Global free trade under the standard (nested) GTAP model
EXP8.CMF        Same as EXP1, but with steady-state capital stock adjustment
                under classical savings behaviour
EXP9.CMF        Same as EXP1, but with steady-state capital stock adjustment
                under Ramsey-type savings behaviour
EXP10.CMF       Same as EXP1, but with rigid real wages
EXP11.CMF       Same as EXP5, but with steady-state capital stock adjustment
                under classical savings behaviour
EXP12.CMF       Same as EXP9, but with global capital markets.  This is a
                very unrealitisic experiment (even more so than
                most other CGE experiments!!!)  but does demonstrate the
                long-run implications of capital mobility (compare to
		experiment 1 and experiment 9.)  Global trade
                liberalization tends to boost the productivity of capital,
                in ROW and also in Japan.  At the same time, there
                is an induced substitution away from savings in Japan.
                The result is a sizeable inflow of capital into Japan
                from the rest of the world (even as there is capital
                accumulation globally and in both regions.)  The result
                is an improvement in the steady-state Japanese trade
                balance of approximately $100 billion, as Japan must
                pay for this foreign-ownedcapital.  Of course, this also implies
                that, in the medium-term (not modelled) the trade balance 
		must have deteriorated first as Japan initially drew 
		down savings and consumed it holdings of global capital. 
		This experiment is benchmarked from an assumption 
		(also very unrealistic) that in the initial data, shares of global
                capital stocks are equal, in value, to installed domestic
                capital, AND that capital is a perfect substitute between
                regions for all investors.  Of course, this is not really
                true, so that this closure may greatly overstate the likely
                capital market effects.  Still, for pedagogical purposes, it does
		illustrate long run implications of capital flows.
