MPSGE Overview
February 27, 2026
At its core, the MPSGE.jl package creates a JuMP.jl model with the necessary constraints of a CGE model. Namely: zero profit, income balance, market clearance, and any auxiliary constraints. This appendix gives the mathematical background on how these constraints are created given a model specified by MPSGE. Read more
Basic Structure of a Scalar MPSGE.jl Model
February 16, 2026
This example will create a model three ways: in MPSGE/GAMS, in MPSGE.jl, and as an explicit algebraic MCP using JuMP.jl. This example will assume that you are familiar with MPSGE/GAMS syntax and are interested in experimenting with Julia. The MPSGE.jl syntax is designed to mirror the MPSGE/GAMS syntax as closely as possible, so if you are familiar with MPSGE/GAMS, you should be able to understand MPSGE.jl with ease. Read more
A Julia/JuMP Introduction
January 31, 2026
This example will introduce the basic syntax of JuMP, a modeling language for optimization problems in Julia. We start with a simple example to introduce syntactic elements of JuMP and compare it to GAMS syntax. Then we will detail a slightly larger example. Read more
Aggregating WiNDC National
January 06, 2026
This example will walk through the code in this repository. This repository contains an example aggregating the WiNDC National dataset to a size that can be run with a trial PATH license (less than 300 variables in the model). Read more
Updating WiNDCNational with the Latest US Data
November 14, 2025
The United States released 2024 updates to Supply/Use tables a few months ago. I have been working on a larger project and have not yet had time to view the updates and incorporate them into WiNDCNational. This past week I spent some time refining WiNDCNational and updating the documentation. Read more
