@alexolegimas Super interesting! A possible reason for the micro–macro gap: who captures the productivity gains.

https://t.co/rsGYJCEaxC finds when productivity rises wage growth expectations barely move. If this generalizes, macro stats based on wages per worker may miss much of AI's impact.

Thanks for inviting me to present "which macro news matters for price-setting?" with @LukasHack_ at @oenb

We use high-frequency event studies & find that inflation & employment surprises imply significant revisions in firms' pricing. Check the paper👇

Hi #EconTwitter, I have an almost complete set of autographs of some of my favorite ifo researchers who were @VfS_econ. To finance my next trip to @ifo_Institut (2. class DB), I will give away a copy of it to the second highest bid.

Very pleased to have joined @almostcertainly and Ian Sheldon over at @TheGeostrata to have discussed the international economic and trade policies of the Trump administration. This was recorded prior to the President's Middle East trip but helps put the deals in context. 1/

Here are some ways in which the world has gotten better.

[Davud Rostam-Afschar @almostcertainly]

What is behind tax elasticities? Often we think firms move when taxes increase. Asked directly, they indeed complain but experimental evidence shows they will not act. Instead tax cuts attract investments. Tax policy works like a ratchet due to home bias: https://t.co/RwkLtNYkJR

📢New WP!
How do firms perceive the competitiveness of their business location and how does that shape their investment decisions?
In a project with @BlesseSebastian, F. Buhlmann and @almostcertainly we study these questions in a firm survey experiment. Check out the thread👇

🎉Thrilled to share my #JMP🎉

It provides a missing piece to understand how people react to income taxation.

Tldr: By changing tax pre-payments governments can - with almost no costs - increase perceived work incentives of secondary earners.
