Project B: QuantEcon Community Library

SCE Working Group 1 · first full-group meeting · 1 October 2026 Project B
Community Library

QuantEcon

A community library of baseline economic models.

Matt McKay · QuantEcon · co-chair

What? Same model. Multiple tools.
Side by side. Built together.

What? · three goals Three goals, each built on the last

Start

Discovery

One place to find every toolkit.

One model, many solutions, discussed openly.

Then

Project A corpus

Real cases for the semantics work.

How?

Community first, corpus second.

How? · step 1 of 3 Start with a directory

How? · step 2 of 3 One model, many solutions, one conversation

How? · step 3 of 3 A corpus for Project A

Future

A designed community space.

Future · prototype Your notebooks, published by model family

Buffer-stock saving · family pagePrototype

The prototype's buffer-stock saving family page: its title, the one-sentence model description and the Family record heading.

Comparison · test pairPrototype

The prototype's comparison chart: the consumption functions from Akshay Shanker's HARK solution and a plain-Python solution generated for the prototype coincide.

Family page One home per model family

Comparison Two methods agree,
never ranked

Future · we propose A space the community shapes

Showcases

Each project’s own choice of problem.

Discussion

A thread beside every solution.

Review

Ideally from another toolkit, credited on the page.

The working group fosters the library

Directory Register your toolkit A short GitHub form. Nothing binding.

Model families Submit a solution Buffer-stock saving first, or propose your model.

Forms: github.com/econ-ark/sce-wg-1/issues/new/choose

Our mission quantecon.org/infrastructure ↗

QuantEcon advances open-source software and open science in economics — freely available, high-quality computational tools and educational resources as a public good for the global economics community.

Which brings me to the ask. This group fosters the library. Its most important contribution isn’t code: it’s the decisions, reviewers from other toolkits, and the consent of the projects involved. It starts with you. So, two things. First, register your toolkit. It’s a short form on GitHub, and nothing in it is binding; the link is on the slide. Second, submit a solution, starting with buffer-stock saving. If that isn’t your model, tell us which one is through the model-family form, and we’ll choose the next families together. In turn, QuantEcon’s mission is open-source software and open science as a public good, and we’ll consult you as we develop the online space. The library is the goal, but it’s the community that produces it and keeps it alive. Let’s build it together. Thank you.
