CGE Modeling Query | Developed using GAMS

I am building a computational general equilibrium model with 37 sectors, combining elements of SAGE and Nohuhiro Hosoe’s dynamic model. I am optimizing the utility equation, and while the file runs without errors, the software reports zero values for all variables. What could be causing this issue, and how can I resolve it?

Hi Esha,

I think without access to your code, it’s challenging to provide direct guidance.

Could you provide more context about what you mean by “zero values”? Does this mean the baseline values are not being replicated? Or are the optimization results all zero?

Best regards,

Hi Rodrigue,

Thank you for your response. I am currently maximizing the consumption function after incorporating CES nested production functions, which account for energy composites, household behavior, government behavior, and private corporations’ behavior. When I ran the code, the parameter values were reported correctly. However, the values of the variables after initialization and within the equation block are being reported as zero.

I am sharing the link to the code file and would greatly appreciate your help in resolving this issue.
