Excellent workshop, great discussions, and a fantastic venue! I presented new work (in progress) with Eckhard Janeba, Felix Köhler and Paul Steger on what the city of Mainz did with its excess tax revenue of 3.3 billion € or about 12,600 per capita due to a business breakthrough

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. Please vote how much you are willing to pay!

New evidence on what moves price-setting 👇

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.

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:

📢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👇

It is our pleasure to introduce the full line up of speakers for the 2025 Oceania Stata Conference, featuring Chuck Huber (@ChuckHuber8), John Kane (@UptonOrwell), Davud Rostam-Afschar (@almostcertainly), Jan Kabatek (@JanKabatek) and David White (@m0457356748) to just name a

🎉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. Thread👇🧵 #EconTwitter

I will be presenting my poster on "Taxes and Pay without Performance: Evidence from Executives" at #CEPRParis2024 today at 12.30. Make sure to check it out!

Gender norms are extremely persistent and constrain women's life opportunities, especially so in poor countries. In my Job Market Paper, I show that grassroots media are an effective policy instrument to address gender norms at scale. #EconJMP #econtwitter

Informal institutions, like local networks and informal bargaining, play a crucial role in governance in lower income countries. But how do these informal institutions shape tax compliance? My job market paper explores this question. #EconJMP #EconTwitter

So, how to balance a priori knowledge & exploration? Before you run your next RCT, check out bbandits at https://t.co/ZTkNdjLley It is a simple solution & available in Stata. Pre-register your full analysis plan with bbandits & let an algorithm do the exploration. It's fun! :)

Yanai and Lercher (2020) show in an experiment that "students without a specific hypothesis were almost five times more likely to discover the gorilla when analyzing this dataset…"

William Easterly cites Samuel Eliot Morison: America was discovered accidentally by a great seaman who was looking for something else" and writes a pre-analysis plan for Columbus. :)
