[User story proposal] Xarray for Economics (Econ-ARK)

Start by reviewing existing posts in src/posts and copy one as a Markdown template with front matter. Shape the post around the proposed Econ-ARK outline, adding images, code blocks, and links only where they support the story. Done means a short, non-technical economics user story is ready for publication on Xarray's blog.

This is a proposal for an economics use case story for Xarray. The story will be published on Xarray's blog (https://xarray.dev/blog).

Why?

We've seen Xarray is used in a number of economics applications (e.g. Econ-ARK) and we've heard its used in other financial modeling context (@max-sixty could likely list a few). A user story blog post showing how Xarray can be used to represent and analyze economics data (in Econ-ARK) would help socialize the concept across the Xarray developer and broader economics communities.

What?

We are targeting a short and non-technical post that illustrates how Xarray is used in the Econ-ARK context. Below is a template outline that you should feel free to modify:

1. Who am I?
2. What problem am I trying to solve?
3. How does Xarray help?
4. Why did I choose Xarray?
5. Current pain points (or ways that Xarray could better serve your use case)
6. Technology I use around Xarray
7. Anything else to know?
8. Links and references

Feel free to insert images or short code blocks if they help you tell your story.

How?

Xarray's blog using Markdown with some front-matter. You can copy one of the existing posts to get started or you can write in a google-doc-like-thing and ask us to do the markdown formatting. If you copy a previous post, use a name like user-story-econ-ark or whatever makes sense for your application.
