I am a macroeconomist, which implies that as a first approximation (a phrase beloved of economists meaning that caveats will follow — extremely important caveats in this case) I think trade is good and more trade is better. It’s not just trade, either — cross-border flows of anything legal: goods, services, people, money, ideas. All of these are good and more of them are better. Globalisation is good.
Except when it isn’t.
