We combine Romer-Romer's identification with Wu-Xia's shadow rate. Using the same identification across conventional and unconventional episodes, we can test differences in MP holding identification constant.

📣 Level up in HANK modeling: BASEforHANK is back!

Following our Winter School, @christianbaye13, @bornecon and I are running the BASEforHANK Spring School, March 1–10, 2027, at @DIW_Berlin.

Want to solve and estimate HANK models for your own research? Join us for hands-on training in Julia with BASEtoolbox.jl; from household problems and equilibrium computation to solving and estimating heterogeneous-agent business-cycle models.

Already working with HANK? We’ll also cover:
Two-country HANK models
Aggregate uncertainty with ambiguity-averse agents
Higher-order perturbation using the DEGM approach

💻 March 1–5: foundations, online
📍 March 8–10: advanced HANK methods, in person at DIW Berlin.
Morning lectures, afternoon hands-on sessions in small groups.
For PhD students, postdocs and professionals—whether you’re getting started or extending your HANK toolkit.

⏰ Apply by November 15, 2026. An early-bird academic discount is available for eligible PhD students and postdocs, with enrollment by December 6. Enrollment runs until mid January 2027.

Details & applications: diw.de/en/diw_01.c.10…

Please share with interested students and colleagues. See you online and in Berlin!

Update to this thread from the NBER SI: our paper is now out as CEPR DP21913. And it has grown: the paper now combines a method, a measurement, and a “new” model of household debt. ralphluetticke.com/files/BBLWW_20…

Today @nberpubs there is great stuff on the solution of HANK models by @GregWKaplan @JavierBianchi7 and @a_auclert @ludwigstraub Rognlie Rigato in the session of @ChristianKWolf @JesusFerna7026 @luigi_bocola.

This is exactly one of the questions of my ERC project: how far can we push perturbation HANK?

So let me share some thoughts and a simple new method that is as fast as a linear solution, but almost as accurate as the fully nonlinear transition.
