@goescarlos Thanks! The opponent at the defense was Ralph Luetticke (University of Tuebingen).

[Matthias Hänsel @MHaensel1]

I haven't used this platform much recently, but can't resist sharing that I successfully defended my PhD thesis earlier this week.

I am now looking forward to start a new job at Aarhus University after the summer.

[Matthias Hänsel @MHaensel1]

Many thanks to my advisors, Lars Ljungqvist and David Domeij, and also everyone else who supported me and/or provided me with comments and feedback over the years.

@ek_oberg The 2023 EER paper by de Graeve and Mazzolini (https://t.co/R5cFiZJtW2) constructs market values of public debt for a range of OECD countries, including Sweden, covering the period 1995-2020, and their database is free to download from the journal website.

@BachmannRudi ..aber nur wenn die NKPC sehr flach ist und die Zentralbank nur begrenzt auf Inflation regiert (Table 2).

[Matthias Hänsel @MHaensel1]

In particular, I show how to use an alternative approach that has a bit more of a "Dynare flavour".

Of course, everything is again coded from scratch in Julia.

[Matthias Hänsel @MHaensel1]

As many people seemed to have appreciated my previous SSJ notebook, I wrote a sequel.

You want to use Sequence Space Jacobians to analyze HANK models but don't warm up to representing models using DAGs? I discuss some alternatives.

@HannoLustig This recent paper studies taxes on price increases in a New Keynesian model: https://t.co/diYBorMVg1

[Matthias Hänsel @MHaensel1]

The paper "HANK faces Unemployment" by by A . Consolo (ECB, @egostino ) and me is now available as ECB Working Paper.

See below for link and short thread. 👇

[Matthias Hänsel @MHaensel1]

@gp_mihalache @pzoch5 I see. For the former case, perhaps ideas from this recent work are interesting: https://t.co/onM5oUg6Jo. It seems to build on SSJ and aims to improve the computation of perfect foresight dynamics after big (and potentially permanent) shocks.

[Matthias Hänsel @MHaensel1]

Thus, spending a bit of time to provide a seemingly useful public resource helped me to attend a cool conference.

I am sharing this to encourage others to do the same.

Below a link to said notebook that I posted a while ago:

Back home after a few intensive days at the Vigo Workshop on Dynamic Macroeconomics.

Not only did I learn a lot about macroeconomics, but also that putting some work into providing public goods can benefit you: 1/n

[Matthias Hänsel @MHaensel1]

In particular, one of the program committee members told me that while there were concerns on how my work would fit the program (no other monetary/HANK papers), he appreciated my SSJ notebook (see below) and thus pushed more for me to be included. 2/3

@TimKriegerFR Ich befürworte das nicht, aber wenn Dienstpflicht dann scheint es gerechter als Pflicht nur für junge oder alte.

[Matthias Hänsel @MHaensel1]

@TimKriegerFR Man könnte auch in jedem Lebensjahrzent (ab 10, bis 70?) zu Dienstzeit verpflichten, wobei Wehr-/Reservedienst, Elternzeit sowie manche Ehrenämter angerechnet werden. Nutzen für BW, gender equality (Papa nimmt elternzeit), "gesellsch. Zusammenhalt" und scheint gerechter.

[Matthias Hänsel @MHaensel1]

@ToreEllingsen1 One could imagine a natural experiment where some couples are unexpectedly or randomly subject to spatial separation, e.g. due to a draft lottery? And compare outcomes for people whose partner got sent away to others initially cohabiting?

[Matthias Hänsel @MHaensel1]

@gp_mihalache @t_holden If it is just on equilibrium outcomes, I am ok with direct nom. rate -> inflation link. After all, inflation rate is the only effect changing nom. rates would have in a flex price model.

[Matthias Hänsel @MHaensel1]

@gp_mihalache @t_holden Indeed. But P changing requires p's changing. Anyway, I think perceived differences here because I (and perhaps schnabel?) was initially thinking of a "transmission chain", i.e. which agent reacts first to what and so on. Models ofc don't take a stance, only on eq outcome.

[Matthias Hänsel @MHaensel1]

@Cmplcation @gp_mihalache @t_holden Indeed, in standard NK models P adjusts immediately in response to shocks.
