Should monetary policy "look-through" the current energy price shock?
➡️Old debate: energy shocks are "temporary" in nature. Central banks should look them through
➡️We argue in our work that the look-through doctrine does not hold when *supply chain uncertainty * is elevated👇
It has become received wisdom in Brussels and Washington that there is a new “euro-sclerosis”: that the EU economy is lagging the US
This view is wrong
A little primer on the measurement of productivity – and why reports of the economic death of Europe are greatly exaggerated🧵
Our paper on the long-term effects of Trump 2.0 tariffs is published in the JIE (open access link below).
TLDR: While tariffs may deliver short-term revenues & welfare gains for the US, the long-term cost of undermining global cooperation is enormous.
A thread on key results🧵
While the USTR tariff calculator cites the findings from Cavallo, Gopinath, Neiman & Tang (2021) it is not entirely clear how they use our findings. Based on our research, the elasticity of import prices with respect to tariffs is closer to 1. If that figure were used instead of 0.25, the implied reciprocal tariffs would come out about four times smaller.
This type of error is why people need to learn macro. The general equilibrium (and exchange rate effects!) are *not* small for a policy of this scope. The assumptions that lead to this formula are not satified, so this formula cannot be used for the stated goal.
📣New working paper: "Tariffs and Monetary Policy"
⏺️I study the effects of tariffs in a workhorse New Keynesian open economy model
⏺️ Key insight: the effect of tariffs depends crucially on the endogenous behavior of monetary policy

New paper on Fiscal Stimulus with Supply Constraints https://t.co/v9uqsB5Iyc
Main idea: fiscal stimulus has a large impact on inflation when firms cannot increase output due to technological supply constraints.
Paper is preliminary, comments are welcome
Interesting and important article: "Why Labor Supply Matters for Macroeconomics" by Richard Rogerson in the Journal of Economic Perspectives.
"In this paper, I argue that labor supply indeed matters for macroeconomics..."

Wir haben das #Wachstumschancengesetz durchgespielt. Wie viel #Wachstum bringt es? Welche #Investitionen werden angstoßen? Was bringt es an zusätzliche #Beschäftigung und wieviele #Steuern werden damit wieder eingespielt? Spoiler: Es ist ein richtiger, aber nur erster Schritt.🧵
Another statement from leading AI experts and entrepreneurs has come out: https://t.co/6VDQC9cSbX. It states “Mitigating the risk of global extinction from AI should be a global priority along other societal-scale risks such as pandemics and nuclear war”.
