Benjamin Born

Thrilled to start as Professor of Macroeconomics at @UniBonn — back to my alma mater and many friends. Thanks to @FrankfurtSchool for 7 great years of research & teaching. Excited for the next chapter!

Economist were SHOCKED to find that well-ranked teams were given unfair advantages and favors over lower-ranked and untraditional teams by non-transparent decision-making process of a professional organization.

@Isabel_Schnabel Thanks, Isabel, for engaging with us. A very stimulating discussion!

Interesting discussion with German-speaking economists about monetary policy, financial stability risks from AI, oil markets, the inflationary impact of fiscal policy, central bank communication and the ability of economies to adapt to shocks.

Just posted some new lecture slides: *Reinforcement Learning for Economists* RL ideas are very powerful, yet criminally underused in economics. I think mostly because RL is not typically taught in grad school -- let's change that! All materials here benjaminmoll.com/lectures/

Only three days remaining to submit your papers to the exciting Frontier Research on Fiscal Policy conference, in the the beautiful Tuscan Hills on October 15-16. Keynotes by Marios Angeletos, Benjamin Born, Roberto Perotti. cepr.org/events/frontie…

VAR Toolbox v4.0 is out 🚀 github.com/ambropo/VAR-To… A collection of MATLAB codes for VAR analysis—estimation, identification, IRFs, variance and historical decompositions. v4.0 is a major overhaul: new identification schemes, LPs now in the toolbox, and a long-promised handbook. Short thread with details below 👇

@FlorinBilbiie Ah, that‘s why A=0 in Germany.

in Y = A·Kᵅ · L¹⁻ᵅ "A" stands for "Air-conditioning", right?

@FlorinBilbiie @SEDmeeting @HanbaekLee @RustamJamilov I have given up on trying to get even one paper in 🤷‍♂️😉

Who has the most papers on the program @SEDmeeting? I initially thought (and was impressed) that it was my Cambridge colleague @HanbaekLee with 3, but just saw that another incredible young talent @RustamJamilov has 4! Anyone matches that? (of course, World Cup-inspired post)

Very much looking forward to visiting @bde_Research next week and presenting our joint work with @LeaBest_ and @ManuelMenkhoff. Thanks for the invitation!

Germany’s temporary 2020 VAT cut boosted consumption spending, especially on durables, by 4.4% according to a HANK model disciplined by survey and scanner data. New paper by @BachmannRudi, @bornecon, Goldfayn-Frank, Kocharkov, Luetticke, and Weber restud.com/a-temporary-va…

Really looking forward to this. Do submit your work if you’re working on fiscal policy!

@BachmannRudi Bad choice. In Bonn scheint die Sonne 😎

München. Regen. Frisur sitzt schlecht.
