Australia National Data
August 29, 2025
Let’s talk about the versatility of WiNDCNational.jl. Since WiNDC is based in the United States our, default data is the United States national table. However, there are, apparently, other countries1. Since my primary collaborator is Australian, let’s load the Australian national table. Read more
Dynamic Ramsey Model
August 22, 2025
I’ve spent the past week focusing on converting a dynamic Ramsey NLP problem into a format suitable for computation using MPSGE. This is the model I presented during the MPSGE Monthly meeting. Read more
Building the WiNDC National Data
August 15, 2025
Today I am going to discuss the build process for the WiNDC National data. I will demonstrate taking the data from the raw Supply/Use tables and transforming it into the final National data product. Read more
WiNDC.jl Clarifying Sets and Parameters
August 08, 2025
In this post I would like to clarify the concepts of sets, parameters and elements in WiNDC.jl. These terms are borrowed from GAMS and have larger mathematical meaning, but it’s not clear what they mean in the context of WiNDC.jl. Read more
Structuring data for API access and WiNDC.jl
August 01, 2025
How should we be storing and using WiNDC and economic data? We currently use sparse arrays to store sets and parameters. However, this approach means every model is tightly coupled to the specific application, for example the National module has fewer parameters than the Household module. This makes it difficult write generic code that can be used across modules. In this post I discuss a new data model that is more flexible and can be used across all modules. Read more
