• Background
• Implementation in the CAPRI Code
• Exercise 2.5
• Result presentation

Open in the CAPRI 2.7 installation the file gams\capmod\inflation_and_trend_interpolation.gms and add the following line at line 85

$IF NOT %MARKET_M%==ON IOE("COMI")    = NO;

The code block should look like this:

*
*      ----- Check if user tries to set endogenous prices
*
$IF NOT %MARKET_M%==ON IOE(MARR)      = NO;
$IF NOT %MARKET_M%==ON IOE("OLIV")    = NO;
$IF NOT %MARKET_M%==ON IOE("PARI")    = NO;
$IF NOT %MARKET_M%==ON IOE("FEED")    = NO;
$IF NOT %MARKET_M%==ON IOE("SUGB")    = NO;
* new line for the scenario
$IF NOT %MARKET_M%==ON IOE("COMI")    = NO;
*
$IF NOT %YANI_M%==ON   IOE(OMYANI)   = NO;

to be stored in gams\userScens

$setglobal SCENDES price increase of 30%
*
*  Baseline scenario
*
$include ..\gams\scen\base_scenarios\CAP_2014_2020.gms
*
*     Example file for exogenous prices changes
