I also presented it at @cepr_org MEF Annual Symposium, @ifo_Institut survey conference & the @bundesbank real time data conference.
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

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/
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: shorturl.at/PkfCC
📢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👇
