4.3.2 MR_DD(r,d,t)
Description:
Purpose and
Occurrence:
Demand coupling equation that associates the flexible demand variable (R_D)
with the level of output from each of the demand devices.
To determine the level of the endogenous energy demand services.
This equation is generated for each region, demand sector and period.
GAMS Routine: MMEQUA.MM (single-region), MMEQUAMM.REG (multi-region).

4.3.3 MR_IVECBND(r,t)
Description:
Purpose and
Occurrence:
Limit on the sum of overall investment and energy costs.
To establish the relationship between total investment and energy costs versus
initial production and labor growth.
This equation is generated in each region for all the projection periods.
GAMS Routine: MMEQUA.MM (single-region), MMEQUAMM.REG (multi-region).
