The program Rice020899.gms sets up the RICE model and solves for the optimal paths of capital, CO2 emissions, and other endogenous variables. It also solves a "base" run in which the negative effects of CO2 are ignored. Rice020899.gms calls the files macro1.gms (a table of input data) and startval.gms (GAMS program to provide starting values for the solution algorithm) via include statements. The startval program is optional, but we recommend it as a way to help the solver find a solution faster. We do not include any put or display statements in Rice020899; output display is left up to the user's preferences. Rice020899 calls MINOS5 as its solver and calls the options file Minos5.opt, which overrides the MINOS5 default to increase the maximum number of iterations.
