If you teach an undergrad international trade course and want some hands-on experience with real data & Stata or R, consider my “Gravity for Undergrads” Chapter. It may be useful in econometrics, undergrad seminars, and undergrad theses. Gravity Rules 💪

Good news on trade. Arne, Mario, Philipp and I construct a dataset on ‘trade specialists’. We find that the trade costs for the specialists are four times lower than for non-specialists. The corresponding welfare gain from globally efficient trade is 80%!

Despite the current challenges and prior doubts regarding the ability of GATT/WTO to promote international trade, the evidence from our meta-analysis is that the WTO/GATT effects on trade have been positive and significant. Happy 30th anniversary & thanks, GATT/WTO!

Because of very important differences in their definitions, types, purposes, implementation, and outcomes, tariffs should not be confused with sanctions …
Well, until Donald Trump redefined tariffs as “Sanctions with Revenues” – the best of both worlds.
