My Economics journey:
1st year undergrad: I want to understand the origins of financial crises and why some countries are much richer than others!
3rd year PhD: I just want to understand why my code doesn't work as it is supposed to.

- An attempt to provide a small public good: A notebook demonstrating how to implement the Sequence Space Jacobian (SSJ) method by Auclert et al. (2021) in Julia. mhaense1.github.io/SSJ_Julia_Note…
- Recently, I have seen various discussions about Heterogeneous Agents/HANK models here. I hope that this new work can help to make progress in the field. tinyurl.com/76uw6e2s
- Happy to see my first (albeit short) publication now out at Economics Letters! TL;DR: Solve DMP models more accurately with this simple trick. Available Open Access thanks to SSE's publishing agreements: sciencedirect.com/science/articl…
- If you saw me present recently, I likely talked about how public debt affects the neutral rate in HANK models, with important implications for monetary policy. Now, @NunoGalo et al. have released (cool) work on the same issue, so I feel I should say sth. about my own paper. 1/nHow does fiscal policy affect monetary policy? Many economists will think of the fiscal theory of the price level (FTPL), but in a new paper we consider an alternative possibility.

- Happy to announce my new working paper.⚡There is so much left to explore in monetary theory!
- On this beautiful day, I am happy to share the abstract of my new working paper:
- The @CIVICA_EU network enabled me to (virtually) attend @FlorianOswald 's Numerical Methods PhD course at SciencesPo Paris and it was nice: sciencespo.fr/ecole-doctoral…
- It was a really cool event, thanks for including me in the program!Yesterday, we had the pleasure of hosting many talented young economists at the third PhD Workshop in Money and Finance organized with #CeMoF (@Stockholm_Uni) @caterinamendic2 @SorryToBeKurt @RoineVestman @bjornhagstromer #econtwitter #riksbankresearch #riksbank
- Replying to @MHaensel1- It uses the paper's simple Krusell and Smith-style model as example environment. - Everything is implemented from scratch, no reliance on a "black box" package - In Julia, it is easy to get your SSJs using Automatic Differentiation
- Replying to @NunoGalo @dandolfa and 2 othersYou might also be interested in my recent work, where I make essentially the same point: dropbox.com/scl/fi/uydwt0s… However, I focus on a two-asset structure and find that the assumptions on how these markets work matters a lot.
- Replying to @MHaensel1Our code is maybe not particularly great, but runs somewhat faster than the Matlab original and is maybe of interest for some. Hence, find a link to our GitHub repo below: github.com/000martin/HANK…
- Having a great time at DSE 2023 Summer School on Deep Learning for Solving and Estimating Dynamic Models.
