Introduction This is a first release of the Second Generation Model code. It includes the Fortran source codes to operate the SGM. The initial conceptual work for the Second Generation Model began in 1990, with implementation starting in 1991. Since then many sponsors and staff have contributed to the model development. Prominent among the sponsors have been the US EPA, presently through the Economic Analysis Branch of the Climate Change Division, Office of Atmospheric Programs, the Integrated Assessment Program within the Office of Science, US Department of Energy, and the Electric Power Research Institute, Climate Change Program. SGM’s documentation (PNNL-14256), overview document (PNNL-14916) and users guide (PNNL-15019-1) are available from http://www.globalchange.umd.edu/?models&page=sgm.

Note that GAUSSJ and ZBRENT are Numerical Recipes routines used in the SGM AN INDEPENDENT LICENCE NEEDS TO BE OBTAINED BY EVERY USER FROM NUMERICAL RECIPES BEFORE THE MODEL CAN BE COMPILED SEE http://www.nr.com/com/storefront.html See SUBROUTINE gaussj(a,n,np,b,m,mp) RETURN END And FUNCTION zbrent(func,x1,x2,tol) RETURN END C (C) Copr. 1986-92 Numerical Recipes Software

SUBROUTINE IMPEXold C********************************************************************** C C This subroutine provides estimates for trade demands/supplies C when less than a full version of the SGM is run. The subroutine C has two modes. The first uses excess demand functions to model C the performance of the relevant external sector. These function C require a price at which there would be zero excess demand C (i.e no trade) and an elasticity. The other fixes imports(negative) C or exports at a level and lets the domestic market solve given this C supply/demand. C C The trade sector is denoted as NIS + 1. The final demand sectors C are all denoted relative to sector NIS, so that the number of productive C sectors can be freely varied.

SUBROUTINE SOLUTN C Modified Newton-Raphson search for market equilibrium prices. C N-R is modified to call a non-derivative based line search when C it finds a discontinuity that causes the derivative to provide C inadequate information for a given market. Also modified in that C derivatives from the previous iteration are recycled for markets C that are within tolerance, which reduces model evaluations. C C********************************************************************** C C Notes and explanations: C C Each period, the markets whose price is fixed or which haven't C come on line are weeded out to avoid a singular matrix error. C Prices are perturbed to get derivatives (elasticities) for the

190

C N-R search. If, after a few calls, any markets are off by a set C amount, the line search SOLVE is called for them before the N-R C procedure continues. SOLVE is also called when an iteration C price causes a market's production to go to zero. In both cases C SOLVE is called because the N-R routine is faced with a discont- C inuity. Also, after 1 iteration, if a market is solved within a set C tolerance, the derivative is recycled for the next iteration, C saving a model evaluation. C C After the first period, the derivatives from the solution set of C the previous period are re-used for the first iteration of the C current period, also potentially reducing model evaluations. C C If the procedure is unsuccessful after a number of tries, the C SOLUTA is called to finish the job. C C*********************************************************************** C .
