FINALLY the field of Economics is waking up to the 20th (yes) century...

I've always loved the questions economics asks, but found the methodology for finding answers to miss out on ideas from computer science

View on HN

Econ has used maths and computers for a long time.

I got lost at part 1.4.1 on page 6. I know python, but what would I need to learn to actually follow this pdf?

looks like linear algebra

Thanks, I'll hit youtube over the weekend

i recommend this series

Thanks, I'll check it out. This is one of those things which I never knew I didn't know about.

Goes very well with your username.

I would recommend 3blue1brown only if you've already covered the material in another way. It's a great way to get some new intuition about things, the videos can help something 'click' and are a pleasant watch with an obviously high production quality. I just don't think they are great for being your first exposure to a topic.

Chapter 21 in the attached pdf gives a brief overview.

There's also a (very challenging, I would guess 150-300 hours time commitment) MIT course online: https://ocw.mit.edu/courses/mathematics/18-06sc-linear-algeb... But it has videos.

I would focus on Chapter 21 in the pdf because it tells you exactly what you need for this application. And supplement it as needed.

Some mathematics background would help. It is a book about quantitative economics after all.

It basically assumes you have at least one year's grad school level background in economics. It does give some overview, but probably not enough to learn it from the book alone.

No, this is advanced undergrad economics or at the most it is in the first year of grad school.

Eh, these authors have been doing computational books for years in econ

Which ideas from CS?

You mean optimization techniques that don't work in the real world of finance?

Even though finance and economics overlap, I think that comment was referring to the social and psychological side of economics.

Was it? Because I have no clue what the poster was referring to.

And economists have been writing code since PL/1.
