Who pays for tariffs? It’s a simple question that’s surprisingly tough to answer. We often see only a rough aggregate measure of prices at the border or the retail price, missing many steps in the chain.
We tackle this in a new paper w Aaron Flaaen, Ali Hortacsu, Felix Tintelnot and Daniel Xu

In 1921 Thomas Edison created an employment test that absolutely captivated America - 146 questions that he asked potential hires. Einstein famously failed it.
